Clinical outcomes of septoplasty and inferior turbinate reduction in the geriatric veterans' population

BACKGROUND: Patients older than 65 years constitute an increasingly large percentage of the patient population that presents to an adult otolaryngology practice due to the increase in life expectancy. The objective of this study is to assess the clinical outcomes of septoplasty with or without inferior turbinate reduction in patients who are 65 years or older. METHODS: This is a prospective nonrandomized longitudinal study of 40 patients aged 65 years or more and who underwent septoplasty with or without inferior turbinate reduction. Patients received Nasal Health Survey (NHS) and General Health Status Short Form (SF-12) questionnaires before and 6 months after surgery. Statistical analysis was performed using the paired t-test. RESULTS: The preoperative NHS score was 52.3, while the postoperative score was 76.6 (p < 0.001). The reported benefit reflected improvement in symptoms (p < 0.001) and reduction in medication usage (p < 0.001). In addition, the SF-12 score improved after the surgery but the difference did not reach statistical significance (p = 0.055). CONCLUSION AND SIGNIFICANCE: Septoplasty and inferior turbinate reduction is beneficial in the veterans' population for patients 65 years or older who present with nasal obstruction and are noted on physical examination to have septal deviation and inferior turbinate hypertrophy.     

A randomised trial comparing the subjective outcomes following septoplasty with or without inferior turbinoplasty

AimsThe surgical management of contralateral inferior turbinate hypertrophy in patients with deviated nasal septum is controversial. In this randomised clinical trial, we aimed to investigate the subjective improvement of nasal symptoms postoperatively in patients undergoing septoplasty with or without inferior turbinoplasty.Material and methodsOne hundred and thirty-seven patients with nasal obstruction, who had unilateral septal deviation and compensatory contralateral inferior turbinate enlargement, were randomised into either septoplasty alone arm (n = 66) or septoplasty combined with turbinoplasty arm (n = 71). Preoperative symptom scores and the subjective perception of the nasal obstruction were compared between two groups of the study using Nasal Obstruction Symptom Evaluation Scale (NOSE) and Visual analog scale (VAS) respectively. The measurements were repeated 6 months after surgery as well as at 1, 2, and 4 years postoperatively.ResultsWith regard to the findings obtained from both scales, both interventions successfully relieved the patients’ complaints of nasal obstruction at almost all postoperative visits when compared with the baseline measurements (P ˂ 0.005 for most comparisons). However, the relief of nasal obstruction was more pronounced in patients undergoing combined intervention at all postoperative visits, except at the 1st follow-up session (P ˂ 0.005). Nasal symptoms of septoplasty alone group began to deteriorate over the period between month 24 and month 48. In contrast, patients undergoing the combined surgery steadily showed symptomatic improvement over the whole period of study.ConclusionsA turbinate reduction surgery should be conducted along with septoplasty to achieve better results in cases suffering from deviated nasal septum with concomitant hypertrophied inferior turbinate.     

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.     

Endoscopic Inferior Turbinate Reduction: An Outcomes Analysis

Objectives/Hypothesis In a previous publication, we introduced an endoscopic technique for the treatment of nasal obstruction caused by inferior turbinate hypertrophy. The technique, a modification of the procedure popularized by Mabry, involves resecting the inferior and lateral aspects of the inferior turbinate with a microdebrider under endoscopic guidance. Our preliminary postoperative results were favorable. All 20 patients experienced improvement by postoperative day 5 and the incidence of complications over the first 6 months after surgery was low. The objective of this study is to perform a long‐term outcomes analysis of patients undergoing the procedure. Study Design Follow‐up survey questionnaire and analysis. Methods We sent questionnaires to 60 patients, ranging from 6 to 40 months after surgery, inquiring about continued use of nasal medications, need for further surgery, presence of adverse effects, and improvement in symptoms. Nasal airway obstruction was assessed on a subjective scoring scale from 1 (no obstruction) to 6 (complete obstruction). Results Of the 28 (47%) patients who returned questionnaires, the severity of daytime nasal obstruction was rated as 2.3 and nighttime nasal obstruction as 2.7. The use of nasal steroids and oral decongestants was 25% and 21%, respectively. Adverse effects were minimal and all but one patient (96%) experienced improvement in their nasal airway. Conclusion These results confirm the long‐term effectiveness of this procedure for the relief of nasal obstruction.     

Long-term results of trimming of the inferior turbinates

The long-term benefit of trimming of the inferior turbinates for nasal obstruction is unclear and our aim was to assess this. Fourteen patients who had had pre-operative nasal symptom scores and anterior rhinomanometry prior to inferior turbinate resection were reassessed at least 7 years post-operatively. Both nasal symptom scores for obstruction and nasal resistance had increased significantly in the intervening time period. Nasal crusting and hypertrophy of the cut inferior turbinate are considered to be responsible for this. Patients should be warned some degree of nasal obstruction may recur post-operatively.     

鼻腔扩容术对鼻塞伴OSAHS患者的主客观症状的影响

目的探讨鼻腔扩容术对伴有鼻塞的阻塞性睡眠呼吸暂停低通气综合征(OSAHS)的主客观症状的影响,为鼻腔扩容术对鼻塞伴OSAHS的患者治疗提供有效的临床依据。方法选择69例伴有鼻塞的OSAHS患者,针对病变的鼻中隔、下鼻甲、中鼻甲、钩突、筛泡等不同部位的病变进行个体化的处理。根据呼吸暂停低通气指数(AHI)及最低动脉血氧饱和度(LSaO2)分为三组:轻度、中度与重度组。通过比较患者手术前后多导睡眠检测(PSG)结果及鼻塞视觉模拟评分量表(VAS)、Epworth嗜睡量表(ESS)、患者鼾声问卷(SS)评分,分析鼻腔扩容术对鼻塞伴OSAHS患者的主客观症状的影响。结果术后6个月随访显示,其中轻度OSAHS患者的AHI、LSaO2及平均动脉氧饱和度(MSaO2)有所升高(P<0.05),VAS、ESS及SS评分都有所降低(P<0.05)。中度OSAHS患者的PSG相关检测指标均无明显变化(P>0.05),VAS、ESS及SS评分有所降低(P均<0.05)。重度患者除VAS及ESS评分有所降低(P<0.05),PSG相关客观指标及SS评分均无明显变化(P>O.05)。结论鼻腔扩容手术可以改善鼻塞为主的OSAHS患者的鼻塞、睡眠打鼾及白天嗜睡等主观症状,对轻度OSAHS患者的疗效优于中重度OSAHS。对鼻塞伴OSAHS患者的治疗有重要的临床意义。     

Acoustic rhinometry predicts tolerance of nasal continuous positive airway pressure: a pilot study

BACKGROUND: Nasal continuous positive airway pressure (nCPAP) is usually the first-line intervention for obstructive sleep apnea, but up to 50% of patients are unable to tolerate therapy because of discomfort-usually nasal complaints. No factors have been definitively correlated with nCPAP tolerance, although nasal cross-sectional area has been correlated with the level of CPAP pressure, and nasal surgery improves nCPAP compliance. This study examined the relationship between nasal cross-sectional area and nCPAP tolerance. METHODS: We performed acoustic rhinometry on 34 obstructive sleep apnea patients at the time of the initial sleep study. Patients titrated to nCPAP were interviewed 18 months after starting therapy to determine CPAP tolerance. Demographic, polysomnographic, and nasal cross-sectional area data were compared between CPAP-tolerant and -intolerant patients. RESULTS: Between 13 tolerant and 12 intolerant patients, there were no significant differences in age, gender, body mass index, CPAP level, respiratory disturbance index, or subjective nasal obstruction. Cross-sectional area at the inferior turbinate differed significantly between the two groups (p = 0.03). This remained significant after multivariate analysis for possibly confounding variables. A cross-sectional area cutoff of 0.6 cm2 at the head of the inferior turbinate carried a sensitivity of 75% and specificity of 77% for CPAP intolerance in this patient group. CONCLUSION: Nasal airway obstruction correlated with CPAP tolerance, supporting an important role for the nose in CPAP, and providing a physiological basis for improved CPAP compliance after nasal surgery. Objective nasal evaluation, but not the subjective report of nasal obstruction, may be helpful in the management of these patients.     

水通道蛋白-4在人鼻息肉组织中的表达及意义

目的 研究水通道蛋白-4(aquaporin4, AQP-4)在鼻息肉组织中的分布并探讨其在鼻息肉形成过程中的机制和作用。方法 采用免疫组织化学方法检测60例新鲜鼻息肉标本和30例肥大下鼻甲黏膜中AQP-4的表达及分布水平,应用两独立样本t检验对检测结果进行对比分析。结果 鼻息肉和下鼻甲黏膜的上皮细胞、固有层腺体细胞、血管及血窦内皮中均可检测到AQP-4分布;鼻息肉上皮细胞、血管及血窦内皮中阳性细胞数均高于下鼻甲黏膜,且差异有统计学意义。结论 AQP-4在鼻息肉上皮细胞和血管及血窦内皮细胞中表达水平明显增高,提示AQP-4在鼻息肉组织中的异常分布可能是鼻黏膜水肿的形成机制之一。

Bipolar radiofrequency volumetric tissue reduction of the inferior turbinates: evaluation of short-term efficacy in a prospective, randomized, single-blinded, placebo-controlled crossover trial

The objective of the study was to assess the short-term efficacy of radiofrequency volumetric tissue reduction (RFVTR) of the inferior turbinates in patients with nasal obstruction caused by turbinate hypertrophy. The study is a prospective, randomized, single-blinded, placebo-controlled, crossover trial. A total of 22 patients (age range 21–72 years; median age 41 years) were randomized into two treatment arms. Using a bipolar radiofrequency system, the first group (VP-group) received RFVTR (verum = V) first (at t1) followed by a placebo treatment (P) 6–8 weeks later (at t2). The PV-group was treated with placebo first at t1 and received RFVTR at t2. Subjects in both groups underwent identical procedures in an office-based setting. Delivery of radiofrequency energy was the only difference between the two groups. The outcome measures assessed were rhinomanometry, physician’s evaluation of the degree of hypertrophy of the inferior turbinates and patients’ estimation of nasal obstruction. Physician and patient evaluations were documented using a score ranging from 0 = none to 4 = severe. Evaluation was performed 6–8 weeks after every intervention. No intraoperative or postoperative complications occurred. Inferior turbinate hypertrophy improved significantly in both groups after RFVTR was performed (VP-group: p < 0.001; PV-group: p = 0.002). Nasal obstruction also decreased only after RFVTR (VP-group: p = 0.004, PV-group: p = 0.002). This study confirmed the safety of bipolar RFVTR as an office-based treatment of nasal obstruction due to inferior turbinate hypertrophy. We could prove that RFVTR is superior to placebo for reduction in turbinate hypertrophy and subjective improvement in nasal obstruction. To our knowledge, this is the first level I study proving the short-term efficacy of a bipolar radiofrequency system. Level of evidence 1b.     

鼻内镜下改良下鼻甲成形术与下鼻甲低温等离子消融加骨折外移术治疗重度慢性肥厚性鼻炎的临床对比研究

目的 将鼻内镜下改良下鼻甲成形术与下鼻甲低温等离子消融加骨折外移术治疗重度慢性肥厚性鼻炎(下鼻甲黏膜、骨膜及骨质均增生肥大、鼻甲形态异常、VAS评分重度)进行对比研究。 方法 回顾性分析124例重度慢性肥厚性鼻炎患者,按照手术方式分为A(64例)、B(60例)两组,A组采用改良下鼻甲成形术,B组采用下鼻甲低温等离子消融加骨折外移术。术前1周、术后6个月、术后12个月分别用VAS标准评分患者鼻腔症状。糖精试验评价术前1周及术后6个月两组患者鼻腔黏膜纤毛传送功能。术前1周及术后6个月测定鼻阻力,评定鼻塞改善情况。 结果 下鼻甲低温等离子消融加骨折外移术组术中出血、手术时间较改良下鼻甲成形组明显减少,且术后并发症较少;术后6个月两种患者鼻塞均有显著改善;两种手术方式对鼻腔黏膜纤毛功能均无明显影响。A组平均手术时间27.80 min、并发症发生率9.38%,B组平均手术时间19.10 min、并发症发生率6.67%。两组患者术后6个月VAS平均评分差异无统计学意义(P=0.12),术后12个月差异有统计学意义(P=0.03)。 结论 改良下鼻甲成形术与下鼻甲低温等离子消融加骨折外移术治疗重度慢性肥厚性鼻炎近期效果(6个月内)都良好,但远期效果(1年以上)改良下鼻甲成形术效果更好,因而建议对于重度慢性肥厚性鼻炎患者应因人而异精准诊疗。     

Long-term self-reported treatment effects and experience of radiofrequency-induced thermotherapy of the inferior turbinates performed under local anesthesia: a retrospective analysis

Nasal obstruction due to inferior turbinate hypertrophy is a common complaint. Radiofrequency-induced thermotherapy of the inferior turbinates (RFITT) under local anesthesia is now a widely used treatment, however reports of assessment of the long-term self-reported benefits and patient satisfaction of the treatment are scarce. This study focuses on the self-reported long-term effects of treatment and experience of RFITT. A questionnaire was sent to 441 patients who underwent RFITT in our clinic to treat symptoms of impaired nasal passage due to enlarged inferior turbinates. All patients had enlarged inferior turbinates on nasal examination. Patients were included if RFITT was done under local anaesthesia, was performed more than a year before the questionnaire was forwarded and on the indication-significant nasal obstruction because of enlarged inferior turbinates. Improvement of nasal breathing (by means of a Visual Analog Scale, VAS), changes in use of nasal spray (VAS), usage of pain medication, patient friendliness of the treatment, complaints reported after treatment, permanent effect of treatment during day and night time and willingness to recommend treatment to others were analyzed. No significant post-operative complications were observed. There was a significant reduction in use of nasal spray and the majority of patients interviewed reported long-term positive effects of RFITT during the daytime. This study shows that RFITT performed under local anesthesia is a valuable, minimally invasive, patient-friendly and well-tolerated treatment in patients with impaired nasal passage due to inferior turbinate hypertrophy.     

Comparative study on the long-term effectiveness between coblation- and microdebrider-assisted partial turbinoplasty

OBJECTIVES: Various surgical methods have been tried to relieve the symptoms of nasal obstruction in patients with inferior turbinate hypertrophy. Recently, coblation that uses the radiofrequency and microdebrider is being increasingly used in turbinate surgery. The aim of this study was to compare the long-term postoperative outcome between the coblation- and microdebrider-assisted partial turbinoplasty. METHODS: We selected 60 patients for this prospective study who had nasal obstruction and hypertrophied turbinate mucosa that was refractory to medical treatment. Thirty patients were treated with coblation (group 1) and 30 patients were treated with microdebrider (group 2). Postoperative changes in degree of nasal obstruction were evaluated prospectively at 3, 6, and 12 months after the procedure. A cross-sectional area of second notch and volume of nasal cavity were compared at 12 months after operation. Operation time, duration of crust formation, postnasal drip, and postoperative bleeding were also compared. RESULTS: Nasal obstruction was improved significantly in both groups at 3, 6, and 12 months after the procedure. However, when compared between two groups, symptom improvement was statistically significant in group 2 at 12 months after surgery. Acoustic rhinometry performed at 12 months demonstrated a significant increase of cross-sectional area of second notch and volume of nasal cavity in group 2 in comparison with group 1. There were no significant differences in degree of postnasal drip, operation time, or duration of crust formation between the two groups. CONCLUSION: This study suggests that microdebrider-assisted partial turbinoplasty is more effective and satisfactory in long-term relief of nasal obstruction and reduction in mucosal volume of anterior head of inferior turbinate.     

A randomised clinical trial of turbinectomy for compensatory turbinate hypertrophy in patients with anterior septal deviations

Turbinectomy is performed at the time of nasal septal surgery by many otolaryngologists. One reason given for this procedure is the presence of a hypertrophied contralateral inferior turbinate. A randomised trial was undertaken to evaluate the relief of nasal obstruction following contralateral turbinectomy with septal surgery. Patients presenting with nasal obstruction who had a unilateral septal deviation and contralateral inferior turbinate enlargement were prospectively randomized to contralateral turbinectomy or no turbinate surgery at the time of septal surgery. Questionnaires and active anterior rhinomanometry were used for evaluation. Twenty-six patients (mean age 31 years) demonstrated a reduction in subjective and objective measures of nasal obstruction (P < 0.05) 8 weeks after operation. There was no intergroup difference, the median total decongested nasal resistance postoperatively in the non-turbinectomized patients was 0.17 kPal-1 s and 0.21 kPal-1 s in the turbinectomized patients. Contralateral inferior turbinectomy does not add to the relief of nasal obstruction beyond that attained by septal surgery in these patients.     

How obesity affects nasal function in obstructive sleep apnea: anatomic and volumetric parameters

IntroductionObstructive sleep apnea is a consequence of upper airway collapse. Any obstructive sector in the upper airway can contribute to pharyngeal collapse. Obesity and obesity-related disorders play an important role in obstructive sleep apnea and its relationship with increased upper airway resistance.ObjectiveThis study was designed to evaluate the relationship between obesity and properties of the nasal cavity in patients with obstructive sleep apnea.MethodsThe study was conducted retrospectively by review of medical records of adult patients. The nasal obstruction symptom evaluation, NOSE instrument, was used to measure nasal obstruction. Sleep breathing disorders were evaluated by polysomnography exams. Nasal volume was obtained by computed tomography scans and volumetric reconstruction of nasal airway. Nasal anatomic alterations were assessed by nasal endoscopy.ResultsAnalysis of 83 patient records, among whom 54 were male and 29 females, found the mean body mass index of 28.69 kg/m². Obese and non-obese groups were determined by using cut-off 30 kg/m². In the comparison between groups, the obese group had a positive and significant correlation with apnea/hypopnea index (p = 0.02), NOSE instrument (p = 0.033) and inferior turbinate hypertrophy (p = 0.036), with odds ratio 1.983 (95% IC 1.048 ? 3.753). nasal septum deviation (p = 0.126) and nasal airway volume evaluation (p = 0.177) showed no significant results.ConclusionObesity was significantly correlated with subjective nasal obstruction, NOSE scale, and inferior turbinate hypertrophy in patients with obstructive sleep apnea. There was no correlation with the nasal volume evaluation.Level of Evidence3b - Individual case-control study.     

Pneumatization of the concha inferior as a cause of nasal obstruction

Chronic nasal obstruction is a common disorder. Hypertrophy of the inferior turbinates is responsible for nasal obstruction more frequently than it is commonly thought. A pneumatized inferior turbinate has recently been described as a cause for nasal obstruction and only two cases have been reported until now. Inferior nasal turbinate develops by endochondral ossification of components of the mesethmoid and ectethmoid. The chondral framework of the inferior turbinate consists of a double lamella and two separate ossification centers that develop between the fifth and seventh month of fetal life. The separate ossification centers meet by the eighth fetal month. During ossification, the inferior turbinate detaches from the ectethmoid and becomes an independent bony structure. During that time the epithelium may misinvaginate into double lamellas and such double lamellas formed by the inferior turbinate may become persistent. A patient was referred to our clinic with headaches and nasal obstruction. A CT scan was performed which showed that the right lower concha was pneumatized. The headache of the patient disappeared after partial resection of the lower and middle turbinate.     

Radiofrequency is a safe and effective treatment of turbinate hypertrophy

OBJECTIVE: To evaluate the safety and efficacy of radiofrequency for reduction of inferior turbinate volume. STUDY DESIGN: Prospective before-and-after trial. METHODS: Fourteen patients complaining of chronic nasal obstruction and failing to respond to medical treatment were prospectively enrolled. All patients presented with inferior turbinate hypertrophy and no septal deformity. Radiofrequency inferior turbinate tissue reduction with three punctures in each turbinate (mean energy/puncture: 342 +/- 36 J, mean duration: 69 +/- 17 s, plateau tissue temperature: 75 +/- 6.4 degrees C). Patients were evaluated before and on days 3, 7, and 60 after intervention. RESULTS: No postoperative pain or complications were reported. Evaluation of nasal obstruction, quantified by visual analogue scale, showed a significant decrease of day time and nighttime obstruction after surgery. Acoustic rhinometry measurements showed that turbinate hypertrophy was significantly reduced in the sitting and supine positions on day 60 after surgery. Saccharin transit times decreased significantly on day 60 compared with preoperative measurements. Ciliary beat frequency, measured in vitro in nasal epithelial cells sampled from the inferior turbinate by brushing, was not significantly different before surgery and on day 60 after surgery. In the same samples, ciliated cells were the most abundant epithelial cell type before and after surgery, although in five cases, moderate numbers of squamous cells were detected on either day 7 or day 60 after surgery. CONCLUSION: Radiofrequency is a safe surgical procedure capable of reducing turbinate volume without altering the nasal mucosa, and causing minimal discomfort for the patient.     

Radiofrequency energy tissue ablation for the treatment of nasal obstruction secondary to turbinate hypertrophy.

OBJECTIVE/HYPOTHESIS: We hypothesized that the success rate of radiofrequency energy (RFe) tissue ablation of the inferior turbinate for nasal obstruction achieved by previous investigators would be improved by using a longer needle electrode and creating two lesions per turbinate. METHODS: Ten patients with nasal obstruction secondary to inferior turbinate hypertrophy were prospectively enrolled. A 40-mm needle delivered RFe to two sites in each inferior turbinate. Patients used a visual analog scale (VAS) to grade nasal obstruction preoperatively and at 1 week and 8 weeks after surgery. Preoperative and postoperative digital images of the nasal cavity were graded for obstruction (0% to 100%) in a blinded manner. RESULTS: All patients (100%) were subjectively improved at 8 weeks. Mean obstruction (VAS) improved from 50%+/-21% to 16%+/-15% (right side) and from 53%+/-29% to 13%+/-13% (left side). Mean improvements were 68% (right side) (P = .004) and 75% (left side) (P = .001). Mean obstruction graded during blinded review of nasal cavity images improved from 73.5%+/-8% to 51%+/-8% (right side) and from 76%+/-6% to 64%+/-7% (left side). Of nine patients using medications for nasal obstruction before treatment, eight (89%) noted no further need for medications at 8 weeks. CONCLUSION: The use of RFe for submucosal tissue ablation in the hypertrophied inferior turbinate is an effective modality for reducing symptoms of nasal obstruction. Improved results may occur by using a longer needle and creating two lesions per turbinate. Of patients in this study, 100% reported improvement of nasal obstruction.     

Effect of submucosal diathermy in chronic nasal obstruction due to turbinate enlargement

Nasal obstruction is one of the most common chronic presenting symptoms encountered by otolaryngologists. In most patients, the cause of nasal obstruction is either nasal septal deviation or turbinate hypertrophy owing to vasomotor or perennial allergic rhinitis. Most cases of hypertrophic turbinate are usually mild and respond to antihistamine therapy, local decongestions, or allergy desensitization; however, surgery is required in some cases. Surgical treatment is controversial, and many surgical methods of treatment have been proposed. We have recently evaluated the results of our experience with submucosal diathermy (SMD) on 51 patients suffering from chronic nasal obstruction. We have found that diathermy demonstrated good results in 78% of the cases at 2 weeks postoperatively and in 76% of the cases 2 months following the procedure. Patients who had no complaints and had good nasal airflow were not followed-up after 2 months. In the present study, we have carried out a long-term follow-up of another group of patients who had undergone SMD diathermy because of hypertrophy of the inferior turbinates. Patients were examined at 2 months postoperatively and after 1 year, with both subjective and objective assessments of nasal breathing. Two months postoperatively 64 of 91 patients (70.3%) experienced subjective improvement in nasal breathing, where as 73 patients (80.2%) had good nasal breathing as indicated with the Gertner-Podoshin plate. During the follow-up year, secondary operations were deemed necessary for 16 patients because of unsatisfactory results of the original procedure. Of these secondary procedures 4 were revision SMD, 9 patients underwent a septoplasty, in 2 patients functional endoscopic sinus surgery was conducted, and 1 patient had a submucosal turbinectomy. This group of patients was excluded from the 1 year follow-up evaluation. At the 1-year follow-up visit, 65 patients (of the 75) were symptom-free with respect to nasal breathing (86.7%), and 67 patients (89.3%) had good nasal breathing as examined with the Gertner-Podoshin plate. No means were apparent for predicting preoperatively which patients would benefit most from submucosal diathermy. Submucosal diathermy is carried out under local anesthesia and can be implemented as an office procedure. It does not require expensive instrumentation and is a safe, effective procedure for improving nasal breathing in patients with chronic obstructive inferior turbinates, both on a short-term and long-term basis.     

Radiofrequency volumetric tissue reduction (RFVTR) of inferior turbinates: a new method in the treatment of chronic nasal obstruction

Twenty-two Caucasians (16 male and 6 female) with chronic bilateral nasal obstruction due to hypertrophic inferior turbinates were followed up over a three-month period. They were assessed by clinical examination, as active anterior rhinometry, and acoustic rhinometry before and after topical decongestion, preoperatively and three months after surgery. All patients were treated by application of radiofrequency-volumetric-tissue reduction (RFVTR, or somnoplasty) to both inferior turbinates. Initial postoperative edematous response disappeared during the first week after RFVTR. Three months postoperatively 20 of 22 patients (91%) reported subjective improvement of nasal patency. The average cross-sectional area for both sides of the nasal cavity (measured at the head of the inferior turbinate (C-Notch) before decongestion) increased in 15 of 22 patients (68.2%). This means a significant improvement from 1.24 to 1.49 cm2 for both sides of the nasal cavity (p = 0.0054). We conclude that RFVTR can safely reduce turbinate volume in a precise manner in patients with nasal obstruction due to hypertrophic inferior turbinates.
