Argon plasma coagulation (APC) for interior turbinates reduction

Authors analyze results of argon plasma coagulation (APC) for interior turbinates reduction in patients with chronic nasal obstruction treated ineffectively with nasal drops. Rhinomanometric parameters, clearance of saccharine test results and cytological examinations were statistically analyzed in 70 patients with bilateral hypertrophy of turbinates treated in ENT Department of Medical University of Silesia in Katowice in years 2000-2001. Control group consists of 30 patients without breathing problems. The obtained results confirmed high effectiveness of APC for interior turbinates reduction. Only patients with first degree in T/S (turbinate/septum) nasal septum deviation were enrolled in both groups.     

Argon plasma coagulation for inferior turbinate reduction

Surgical reduction of the inferior turbinate remains a widely used therapy for nasal obstruction caused by hyperplastic turbinates. Current methods are costly and time-consuming, require nasal packing, and cause extended postoperative swelling. Argon plasma coagulation (APC) is a new, innovative technique in otorhinolaryngological surgery that is based on high-frequency electrical current. The current is transmitted through ionized argon gas (plasma) contact-free to the tissue surface and creates a coagulation and devitalization zone with limited penetration. Forty-five patients with nasal obstruction were treated under local anesthesia for reduction of the inferior turbinates with APC. Seventy-six percent of the patients reported an improvement of postoperative swelling within the first week. After 3 months, 86% reported having better nasal airflow than they had before the operation. Macroscopically, after 4 weeks the turbinate was covered by normal mucosa in 51% of the patients. Crust formation was minimal, and no bleeding occurred. Turbinate reduction with APC is an alternative technique with many advantages, and the results are comparable to those of standard techniques. Ninety-five percent of the patients were satisfied with the operation.     

Long-term results of inferior turbinate reduction with argon plasma coagulation

OBJECTIVES: Surgical reduction of the inferior turbinates is a commonly used therapy in patients with hyperplastic inferior turbinates when medical management remains ineffective. Current surgical methods have disadvantages (e.g., necessity of nasal packing, extended postoperative swelling, and high costs). Theoretical considerations render argon plasma coagulation (APC) a promising new therapeutic approach. STUDY DESIGN: In a prospective study, 121 patients with chronic nasal obstruction were treated for inferior turbinate reduction with APC. Hyperplasia of the nasal turbinates was diagnosed rhinoscopically and endoscopically and confirmed rhinomanometrically. The mean follow-up period was 12 months, ranging from 10 to 16 months. The treatment results were evaluated by a questionnaire, rhinomanometric findings, and electron microscopic studies of the nasal mucosa. In 50 patients a ciliary function test was performed preoperatively and postoperatively. METHODS: Argon plasma coagulation, a high-frequency electrosurgery, has been used for volume reduction of the inferior turbinate in local anesthesia. RESULTS: Seventy-six percent of the patients reported an improvement of the postoperative swelling within the first week. After 6 weeks, macroscopically the turbinates were re-epithelialized by normal mucosa in 63% of the patients. Electron microscopic studies after 3 months verified normal cilia. After 12 months, 83% of the patients stated that they had a better nasal airflow than preoperatively. Crust formation was minimal. No bleeding or impaired ciliary function occurred. Ninety-five percent of the patients were willing to undergo the same operation again. CONCLUSION: The long-term results have proved APC to be an effective and easy-to-perform alternative for inferior turbinate reduction with comparable results to other established surgical methods.     

Comparison of microdebrider-assisted inferior turbinoplasty and submucosal resection for children with hypertrophic inferior turbinates

OBJECTIVES: The aim of this study was to compare the effectiveness and safety of microdebrider-assisted inferior turbinoplasty (MAIT) with submucosal resection (SR) for children with hypertrophic inferior turbinates. MATERIALS AND METHODS: One hundred and twenty children with chronic nasal obstruction due to hypertrophic inferior turbinates were enrolled. These children were randomly assigned to receive SR of the inferior turbinate (n=60) or MAIT (n=60). Ten children who did not appear to display any nasal discomfort served as normal controls. Surgical-outcome was evaluated with respect to four distinct parameters: nasal endoscopy, subjective assessment of nasal symptoms by the patient using a visual analogue scale, anterior rhinomanometry, and saccharin test. These evaluations were conducted before surgery and at 1 week, 1 and 3 months after surgery. RESULTS: In the SR group, turbinate edema was decreased significantly at 1 and 3 months after surgery (p<0.05). Nasal secretions and crusting were increased significantly (p<0.05) in the SR group at 1 week after surgery and then decreased significantly at 1 and 3 months after surgery. In the MAIT group, turbinate edema and nasal secretions were decreased significantly at 1 and 3 months after surgery (p<0.05). Nasal crusting was not observed after surgery. Subjective complaints including nasal obstruction, sneezing, rhinorrhea and hyposmia were significantly improved in both groups from 1 month after surgery (p<0.05). Rhinomanometric assessment did not reveal significant improvement until 3 months after surgery in both groups. Saccharin transit time was significantly increased (p<0.05) compared to baseline at 1 week after surgery in the SR group but was not significantly different in the MAIT group. CONCLUSION: MAIT and SR are both effective at relieving nasal obstruction due to the presence of hypertrophic inferior turbinates. MAIT is superior to SR with regard to preserving the nasal mucosa.

Submucosal bipolar radiofrequency thermal ablation of inferior turbinates: a long-term follow-up with subjective and objective assessment

OBJECTIVE: To assess the efficacy and morbidity of bipolar radiofrequency thermal ablation of the inferior turbinates in patients with nasal obstruction caused by turbinate hypertrophy. STUDY DESIGN: Prospective, nonrandomized study and outpatient treatment. METHODS: Twenty patients (age range, 23-77 y; median age, 52 y) enrolled in the study. There was one dropout. All the patients had nasal blockage despite medical treatment. Bipolar radiofrequency thermal ablation was delivered to inferior turbinates at 100 kHz with a voltage root mean square value of 168 to 182. The preoperative and postoperative nasal functions were investigated by immediate and long-term visual analogue scale (VAS) scores of symptom parameters, olfactory thresholds, saccharine transit time, rhinomanometry, and acoustic rhinometry. The follow-up was conducted at 1 week and 3, 6, and 12 months. RESULTS: The VAS scores of subjective complaints (nasal discharge, itching, sneezing, crusting) decreased, and the VAS scores of evaluation of the effectiveness (frequency of nasal obstruction, degree of nasal obstruction, and patient satisfaction) increased statistically significantly in the 12-month follow-up without relapses. There were no adverse effects on nasal epithelial clearance time and olfactory functions. In rhinomanometry the changes in total nasal resistance and response to the vasoconstrictor agent were not statistically significant. In acoustic rhinometry the change in the sum of both nasal cavity volumes from nostril to 5 cm was statistically significant 6 and 12 months after the treatments. The difference between the preoperative and postoperative vasoconstrictive effect was not statistically significant. CONCLUSION: The bipolar radiofrequency thermal ablation of inferior turbinates is a promising alternative, which should be considered when planning inferior turbinate interventions.     

Argon plasma surgery for treatment of inferior turbinate hypertrophy: a long-term follow-up in 157 patients

Chronic nasal obstruction is a common disorder, mostly caused by hypertrophic inferior turbinates. In cases of nonresponse to conservative medical management, the surgical reduction of the inferior turbinates is often required. Surgical techniques for the reduction of hyperplastic nasal turbinates include monopolar or bipolar coagulation, partial or total reduction of the turbinates with a conchotome or scissors and laser surgery with Nd:YAG, CO(2) or KTP. Argon plasma coagulation (APC) is a new, innovative technique in otorhinolaryngology which is based on high-frequency electrocoagulation with an argon gas source. The fast and short surgery times, the absence of hemorrhagic complications and, in rhinosurgery, the complete abstention from any kind of nasal packing are remarkable. Between March and November 2000, a group of 157 patients with symptoms of nasal obstruction due to hypertrophic inferior turbinates were treated using APC, at the Otorhinolaryngology Surgery Department of the Hospital of Dolo (Venice). The follow-up period was 24 months. Rhinomanometry was performed to objectively measure the nasal obstruction and to verify the postoperative improvement. The Student t test was used for statistical data. After 24 months, 87% (p < 0.001) of the patients reported to have a better nasal airflow than before the operation. None of the patients needed a nasal packing after APC surgery. The indication, advantages, complications, controversies and long-term results of the treatment with APC in rhinosurgery are reviewed and discussed.     

Comparison of the effects of radiofrequency tissue ablation,CO2 laser ablation,and partial turbinectomy applications on nasal mucociliary functions

OBJECTIVES: One of the major causes of chronic nasal airway obstruction is disease of the inferior turbinate. However, there is no agreement on how to deal with this problem. Comparison was made of the nasal functions after treatment by radiofrequency tissue ablation, laser ablation, and partial turbinectomy using subjective symptom scores and objective tests. STUDY DESIGN: Prospective, randomized clinical trial. METHODS: The study was conducted on three groups of 45 adult volunteer patients with symptoms and signs of nasal obstruction and stuffiness related to enlarged turbinates. In group A, laser ablation was applied to the inferior turbinate on one side and partial turbinectomy to the inferior turbinate on the other side. In group B, radiofrequency tissue ablation was applied to the inferior turbinate on one side and partial turbinectomy to the inferior turbinate on the other side. In group C, patients who were not treated by any surgical techniques were the control subjects. Clinical examinations, visual analogue scales, rhinomanometry, and isotopic study of nasal mucociliary transport time were used to assess treatment outcomes. RESULTS: At 12 weeks after surgery, the nasal mucociliary transport time results were compared in the same patients. The average time was 25.60 minutes on the side where laser ablation was applied and 11.40 minutes on the side where partial turbinectomy (PT) was applied. In the patients on whom radiofrequency tissue ablation and partial turbinectomy were applied, the average nasal mucociliary transport time was 10.33 minutes on the radiofrequency tissue ablation side, whereas it was 11.33 minutes on the partial turbinectomy side. Rhinomanometric measurements demonstrated a significant decrease in nasal resistances at 12 weeks in both sides in groups A and B. CONCLUSIONS: In the study it was demonstrated that radiofrequency tissue ablation to the turbinate is effective in improving nasal obstruction objectively and in preserving nasal mucociliary function. Laser ablation of the turbinate is effective in improving the nasal obstruction; however, it disturbs the mucociliary function significantly. With the partial turbinectomy technique, results obtained were similar to the results with the radiofrequency tissue ablation technique.     

Argon plasma surgery for the inferior turbinate of patients with perennial nasal allergy

OBJECTIVES: Argon plasma coagulation (APC) is a new electrosurgical modality. The advantages of APC are coagulating of the target tissue without contact and the creation of uniformly deep devitalized and coagulated zones. The objectives of the present study were to determine the clinical effects of APC for the inferior turbinate of patients with nasal allergy and to clarify the histological changes in the mucosa after APC. STUDY DESIGN: In a prospective study, 95 patients with perennial nasal allergy were treated with APC. Nasal symptoms and intranasal findings were evaluated preoperatively and 1, 3, and 6 months, and 1 year after the APC. Mucosal specimens from the turbinates were examined under light and electron microscopy. RESULTS: Nasal stuffiness was improved in 77 of 79 (97.5%) patients after 1 month, in 50 of 51 (98.0%) patients after 3 months, in 20 of 23 (87.0%) patients after 6 months, and in 9 of 12 (75.0%) patients at 1 year after the APC. Rhinorrhea was improved in 46 of 75 (61.3%) patients after 1 month, in 40 of 51 (78.4%) patients after 3 months, in 16 of 21 (76.2%) patients after 6 months, and in 6 of 10 (60.0%) patients at 1 year after the APC. The sneezing was improved in 32 of 54 (59.3%) patients after 1 month, in 21 of 35 (60.0%) patients after 3 months, in 10 of 14 (71.4%) patients after 6 months, and in 6 of 8 (75.0%) patients at 1 year after the APC. In the intranasal findings, congestion of the inferior turbinate improved in 75 of 76 (98.7%) patients after 1 month, in 49 of 52 (94.2%) patients after 3 months, in 20 of 23 (87.0%) patients after 6 months, and in 7 of 11 (63.6%) patients at 1 year after the APC. The nasal discharge was reduced in 40 of 75 (53.3%) patients after 1 month, in 32 of 52 (61.5%) patients after 3 months, in 15 of 22 (68.2%) patients after 6 months, and in 5 of 11 (45.5%) patients at 1 year after the APC. No patients needed nasal packing after the APC. CONCLUSIONS: This is the first report on the clinical effects of turbinate surgery for nasal allergy using APC. APC was useful fer turbinate surgery of nasal allergy, especially for nasal stuffiness and congestion of the turbinate.     

Microdebrider-assisted versus laser-assisted turbinate reduction: comparison of improvement in nasal airway according to type of turbinate hypertrophy

A case-control study was conducted at our secondary referral hospital to compare the efficacy of microdebrider-assisted turbinate reduction (MATR) with laser-assisted turbinate reduction (LATR) and to evaluate their efficacy according to types of hypertrophic inferior turbinates. All patients who underwent only inferior turbinate surgery for refractory nasal obstruction were included. The required minimum follow-up period was 3 months postoperatively. Thirty-seven patients were enrolled in this study-22 in the MATR group and 15 in the LATR group. The patients were subclassified into mucosal (n = 14) and bone (n = 23) hypertrophy groups. Subjective (visual analogue scale) and objective (endoscopic score) assessments were performed prior to surgery and 3 months after surgery. Generally, the visual analogue scale and endoscopic score were significantly improved after surgery, in both the MATR and the LATR groups. In the MATR group, the visual analogue scale and endoscopic score improved regardless of type of hypertrophy. However, in the LATR group, these measurements improved only in cases with mucosal hypertrophy. We conclude that both MATR and LATR are good surgical techniques in patients with chronic hypertrophic inferior turbinates who have substantial nasal obstruction. However, MATR is superior to LATR, especially in cases with bone hypertrophy.     

A safe, alternative technique for inferior turbinate reduction

OBJECTIVE: Submucous resection of the inferior turbinates is a conventional technique for reducing their size to achieve patent nasal airways in situations where an enlarged turbinate contributes to airway obstruction. Many techniques and complications have been described in the past. We describe a new inferior turbinate reduction technique performed with powered instrumentation and assess its success and complication rates. STUDY DESIGN: A prospective study of 120 consecutive patients who underwent submucous resection of the inferior turbinates with a microdebrider. METHODS: Patient questionnaires were used for subjective assessment of symptoms before and after the procedure. We graded each patient's inferior turbinates for size from I to III before and 6 weeks after surgery for objective analysis. RESULTS: The common complications of standard submucous resection of inferior turbinates include excessive resection, postoperative bleeding, and crusting. The advantage of the microdebrider technique is the precise control of the amount of tissue and location of tissue that is removed on a submucosal plane. The complications encountered with this technique are limited to postoperative bleeding that occurred in 1.6% of patients. There was no crusting or excessive removal of tissue. CONCLUSION: The results show that submucous resection of inferior turbinates with a microdebrider is a safe method of achieving turbinate size reduction with minimal morbidity.     

Diode laser treatment of hypertrophic inferior turbinates and evaluation of the results with acoustic rhinometry

Inferior turbinate hypertrophy is the most common cause of chronic nasal obstruction. When conservative medical treatment options fail in patients with inferior turbinate hypertrophy, reduction of the inferior turbinate can be performed using surgical techniques. Laser-assisted turbinate surgery has the advantages of limited tissue trauma and reduced bleeding. We evaluated the effectiveness and outcomes of using a diode laser (λ?=?980?nm) in turbinate reduction. Our study included 62 patients with symptoms of nasal obstruction due to hypertrophic inferior turbinates, who did not respond to medical treatment (≥1?year). Patients were treated with diode laser between January 2009 and December 2010 in our ENT (ear, nose, and throat) department. Subjective outcome of severity of nasal obstruction was assessed on a standard 10-cm visual analog scale (VAS). Acoustic rhinometry was used to measure nasal patency. The cross-sectional areas 1, 2, and 3 and the volumes between 2.5 and 5.5?cm were measured. VAS scores and acoustic rhinometry measurements were performed preoperatively and 1, 6, and 12?months after surgery. The mean follow-up was 13.1?±?1?months. The mean operation time was 3?min per turbinate; no nasal packing was necessary. We did not observe any major complications. Both subjective and objective evaluations showed significant improvement. VAS scores improved, the mean MCA2, MCA3, and V2–5 measurements increased significantly 1?year after surgery. In the first year after surgery, 53 of 62 (85.4%) patients reported marked improvements in nasal breathing. Our results showed that, objectively and subjectively, the success rates in diode laser-assisted turbinate reduction were satisfactory. The diode laser, being one of the most portable and least expensive of the lasers available for turbinate surgery, makes it possible for turbinate reduction to be performed under topical anesthesia within a short period of time with excellent patient acceptance.     

Histopathology of the inferior turbinate with compensatory hypertrophy in patients with deviated nasal septum

OBJECTIVE: To measure the dimensions, composition, and possible structural and/or histopathological changes of the compensatory hypertrophic inferior turbinate in patients with deviated nasal septum. STUDY DESIGN: A prospective, nonrandomized, and morphometric study. METHODS: Nineteen patients with deviated nasal septum and compensatory hypertrophy of the inferior turbinate in the contralateral nasal cavity underwent surgery for correction of nasal obstruction. Patients' specimens were compared with those of a control group consisting of 10 inferior turbinates removed at autopsy. Quantitative measurements of the inferior turbinate histological sections were carried out and included the width of the layers and morphometric calculations of the relative proportions of the soft tissue constituents. Also, qualitative study was performed to detect pathological changes. RESULTS: Of all layers, the inferior turbinate bone underwent a twofold increase in thickness and manifested the most significant expansion (P < or =.001), whereas the contribution of the mucosal layers to the inferior turbinate hypertrophy was modest. The morphometric analysis revealed a larger proportion of venous sinusoids in hypertrophic turbinates, but the difference was small and statistically insignificant. Qualitative assessment disclosed normal mucosal architecture in all inferior turbinates with compensatory hypertrophy. Eleven remained intact, while eight disclosed mild to moderate pathological changes. CONCLUSIONS: The data gathered in the present study are of importance to the decision-making process regarding turbinate surgery. The significant bone expansion and the relative minor role played by the mucosal hypertrophy would support the decision to excise the inferior turbinate bone at the time of septoplasty.

Long-term efficacy of microdebrider-assisted inferior turbinoplasty with lateralization for hypertrophic inferior turbinates in patients with perennial allergic rhinitis

Objectives: The aim of the study was to evaluate the long‐term efficacy of microdebrider‐assisted inferior turbinoplasty with lateralization (MAITL) compared to submucosal resection for hypertrophic inferior turbinates. Study Design: Surgical outcomes were evaluated with respect to visual analogue scale, anterior rhinomanometry, and saccharin test results. Methods: From January 2002 to December 2006 inclusively, 160 patients with perennial allergic rhinitis and hypertrophic inferior turbinates were enrolled into this study. The patients, all suffering from chronic nasal obstruction, were randomly classified into two groups, MAITL group or SR group, each comprised of 80 patients. Ten patients who did not display any nasal discomfort served as normal controls. For the submucosal resection group, patients underwent submucosal resection of the inferior turbinate, whereas patients in the MAITL group underwent microdebrider‐assisted inferior turbinoplasty with lateralization. Assessments (visual analogue scale, anterior rhinomanometry, and saccharin test) were conducted prior to the surgery and 1, 2, and 3 years after completion of surgery. Results: Compared to preoperative values, subjective complaints including nasal obstruction, sneezing, rhinorrhea, and snoring improved significantly in both groups at 1, 2, and 3 years after surgery in both groups (P < .05 for all). Rhinomanometric assessment also showed significant improvement at 1, 2, and 3 years postoperatively in both groups (P < .05 for all). Saccharin transit time was significantly decreased (P < .05 for all) compared to preoperative values 1, 2, and 3 years after surgery in both groups. Conclusion: Microdebrider‐assisted inferior turbinoplasty with lateralization appears to be as effective as submucosal resection at relieving nasal symptoms and decreasing total nasal resistance and saccharin transit times for more than 3 years in patients with perennial allergic rhinitis who have had substantial nasal obstruction.     

Laser treatment of rhinitis—1 year follow-up

Laser cautery of the inferior turbinates for the treatment of rhinitis has been shown to be as effective as sub-mucosal diathermy in the short-term and to produce less morbidity. However, the long-term effects are unknown. A cohort of patients who were treated by either of these methods were reviewed 1 year after treatment. Subjective and objective measurements of airway obstruction were performed using a linear analogue scale and a nasal peak inspiratory flowmeter. The results obtained were compared with those recorded pre-operatively, 3 days post-operatively and 6 days post-operatively. In contrast to the results of sub-mucous diathermy of the inferior turbinates for the treatment of rhinitis, the reduction in subjective nasal airway obstruction obtained by laser cautery to the inferior turbinates is maintained 1 year after surgery. Neither method of turbinate reduction was associated with a sustained objective improvement in nasal airway patency as measured by peak nasal inspiratory flow rate determinations.     

Argon plasma coagulation in the treatment of nonallergic hypertrophic inferior nasal turbinates

PURPOSE: Various surgical procedures have been recently proposed for the treatment of hypertrophic inferior nasal turbinates as a result of the advances made in medical technology and growing public demand for minimally invasive therapies. The aim of this study was to evaluate the safety and efficacy of the argon plasma coagulation technique for inferior turbinate reduction in a homogeneous series of patients with nonallergic inferior turbinate hypertrophy.Material and methods: Twenty symptomatic patients underwent argon plasma coagulation surgical treatment under local anesthesia and were clinically followed up after 1 month and then every 3 months (anterior rhinoscopy and nasal endoscopy). Diagnostic evaluations using active anterior rhinomanometry were made after 3 and 12 months. RESULTS: All of the patients reported a postoperative improvement in nasal swelling and patency. No postoperative complications were observed. Rhinomanometry after 12 months showed a reduction in mean total resistance from the pretreatment level of 1.06 Pa s/cm(3) to 0.49 Pa s/cm(3). There was also a statistically significant reduction in nasal resistance for each of the investigated conditions (inspiration and expiration in orthostatism and clinostatism). CONCLUSIONS: Argon plasma coagulation is a safe and efficacious procedure for the minimally invasive treatment of inferior turbinate hypertrophy, which can be performed under local anesthesia in an outpatient setting with little discomfort for the patient.     

Changes of nasal function after temperature-controlled radiofrequency tissue volume reduction for the turbinate

OBJECTIVES: Temperature-controlled and temperature-monitored radiofrequency tissue volume reduction (RFTVR) for the turbinate is a new treatment modality for nasal obstruction secondary to turbinate hypertrophy. We compared the nasal functions after the treatment ofRFTVR and laser vaporizing turbinoplasty (LVT) using subjective symptom scores and objective tests. STUDY DESIGN: Prospective, randomized clinical trial. METHODS: Twenty-four patients with nasal obstruction secondary to inferior turbinate hypertrophy were prospectively evaluated from March 1999 to October 1999 at Seoul National University Hospital (Seoul, Korea). Sixteen patients were treated with RFTVR, and eight patients with LVT. The preoperative and postoperative nasal functions were investigated by visual analogue scale of symptoms, butanol threshold test, saccharine test, acoustic rhinometry, rhinomanometry, and ciliary beat frequency. RESULTS: At 8 weeks postoperatively, the severity and the frequency of nasal obstruction improved subjectively in 81.3% and 93.8% of RFTVR group and in 87.5% and 87.5% of LVT group, respectively. Significant improvement of nasal symptoms began from 2 to 3 days after the operation in the RFTVR group, whereas there was significant improvement of nasal symptoms at 8 weeks after operation in the LVT group. However, objective nasal functions including nasal volume and total nasal resistance were significantly improved at 8 weeks after surgery in both groups. Among patients reporting symptoms of hyposmia, 55.6% of RFTVR group and 63.6% of LVT group showed improved olfaction. Saccharin transit time and ciliary beat frequency were preserved after RFTVR CONCLUSION: RFTVR for the turbinate may be useful as an alternative approach for the treatment of chronic turbinate hypertrophy.     

Comparison of ultrasound turbinate reduction, radiofrequency tissue ablation and submucosal cauterization in inferior turbinate hypertrophy

Chronic nasal obstruction owed to chronic hypertrophic rhinitis is a common cause of nasal airway obstruction. In cases unresponsive to conservative treatment, various surgical techniques are commonly performed, but the issue of the optimal surgical procedure is still controversial. The objective of the present study was to evaluate the effectiveness and safety of ultrasound treatment of the hypertrophied inferior turbinates, which is a technique recently applied in rhinologic surgery. We aimed, also, to compare this method with the radiofrequency cold coblation turbinate reduction and the traditional submucosal monopolar inferior turbinate cauterization. We studied prospectively 60 patients with chronic hypertrophic rhinitis of nonallergic etiology, who underwent different surgical methods of turbinate reduction, divided into two groups: (1) in 30 patients, inferior turbinate volume reduction using ultrasound procedure on the left side and monopolar diathermy on the right was performed; (2) in 30 patients, radiofrequency coblation technique on the left side and ultrasound turbinate reduction on the right side was undertaken. Subjective evaluation of nasal obstruction and pain was performed using visual analog scales and objective evaluation of the surgical outcome was obtained using active anterior rhinomanometry and acoustic rhinometry. Examinations were performed preoperatively, and 1, 3 and 6 months after surgery. Both subjective and objective evaluation showed significant postoperative improvement in all cases. The best results were obtained with the ultrasound procedure, and second with the radiofrequency technique. The least improvement was observed in the electrocautery group, although its results did not differ significantly from the radiofrequency group. It may be, thus, concluded that ultrasound turbinate reduction is an effective and safe procedure for the management of chronic hypertrophic rhinitis, in patients failing to respond to medical treatment. Using this method, better results were obtained in decreasing subjective symptoms and nasal obstruction, in comparison with radiofrequency and electrocautery.     

Surgical treatment of inferior turbinate hypertrophy with argon plasma: a long-term follow-up in 157 patients

Surgical treatment of the inferior turbinate in patients with chronic hypertrophic rhinitis that does not respond to medical treatment is a well established procedure. CO2 laser, YAG laser, KTP laser, conventional electrocautery, cryotherapy, chemosurgery and turbinectomy or submucosal turbinectomy have been performed for the removal of nasal obstruction. Argon Plasma Coagulation (APC) is a new, innovative technique in Otorhinolaryngology which is based on high-frequency electrocoagulation with an argon-gas source. The shorter surgical times, the absence of hemorrhagic complications and, in rhinosurgery, not requiring any kind of nasal packing are remarkable. Between March and November 2000, a group of 157 patients with symptoms of nasal obstruction due to hypertrophic inferior turbinates were treated using APC, at the Otorhinolaryngology Surgical Department of the Hospital of Dolo (Venice). The follow-up period was 24 months. Rhinomanometry was performed to objectively measure the nasal obstruction and to verify the postoperative improvement. The Student t-test was used for statistical data. After 24 months, 87% (p < 0.001) of patients reported to have a better nasal airflow than before the operation. None of the patients needed a nasal packing after APC surgery. We review and discus the indication, advantages, complications, controversies and long-term results of the treatment with APC in rhinosurgery.
