Paper-patch myringoplasty with CO<Subscript>2</Subscript> laser for chronic TM perforation

Chronic tympanic membrane (TM) perforations are a common problem in otolaryngology. However, there are controversies of how best to treat TM perforation. Recently, we successfully managed TM perforation with paper patch after trimming the perforated TM margin with the CO(2 )laser. The purpose of this report is to demonstrate the trial of this method and effectiveness. The authors conducted a retrospective case series from March 2000 to January 2005. Ninety patients underwent paper-patch myringoplasty with the CO(2) laser. The procedure was performed in an office setting under local anesthesia. We investigated perforation size and postoperative success rate. Successful closure of the TM was achieved in 52.2% of cases (47/90) without any severe complication. The procedure was successful in 16 of 19 (84.2%) cases in perforation smaller than 2 mm, 19 of 29 (63.0%) cases when the size was 2-4 mm, 10 of 25 (40.0%) cases when the size was 4-6 mm, and 2 of 17 (11.8%) cases when the size was >/=6 mm. A significant difference was found: Perforation with <4 mm had the higher closure rate (chi(2) test, P < 0.01). There was no correlation between the size of perforation and the number of patch graft (chi(2) test, P > 0.05). The results showed paper-patch myringoplasty after CO(2) laser trimming is simple and safe to perform, and suitable as an outpatient procedure, especially in small perforations (<4 mm).     

Role of transoral CO<Subscript>2</Subscript> laser surgery for severe pediatric laryngomalacia

Controversy exists as to the preferred treatment modality for managing refractory pediatric laryngomalacia (LM). Simultaneous bilateral procedures have been associated with supraglottic stenosis. Unilateral operations have a higher rate of secondary intervention. This prospective study was conceptualized to ascertain a preferred approach. A secondary goal was to correlate the surgical outcome with presenting symptoms and signs. Twenty-two children with severe LM met the criteria for enrollment. Bilateral CO₂ laser-assisted supraglottic laryngoplasties were performed in all cases. The procedure mainly consisted of division of the aryepiglottic fold. Nineteen (86%) patients met our defined success criteria. There were no surgical complications. Bilateral supraglottic laryngoplasty has a role in the management of severe refractory LM.     

The use of forced ventilation during microlaryngoscopy with laser CO<Subscript>2</Subscript>

CO(2) laser is currently used in the treatment of laryngeal lesions. The technique leads to vaporisation of the tissues on which it is focused, resulting in the production of smoke that remains in the laryngoscope and in the area of the exposed larynx. The fumes can only be partially removed with an aspiration tube. As a result, the vision of the operative field becomes obscured, thus making it difficult to perform surgery. We present a method to resolve this problem consisting in forced ventilation of the air present in the laryngoscope and the exposed larynx. Simultaneous use of the forced ventilation air and the aspiration tube permits a more efficient withdrawal of fumes from the operative field and a better view of the larynx for the surgeon. Since 1986, we have performed 200 CO(2) laser cordectomies in patients with early stage glottic cancer without any kind of complication.     

Transoral CO2 laser surgery for supraglottic cancer

There are several therapeutic options for laryngeal cancer, including those that provide a functional preservation without worsening the oncological results, such as transoral laser microsurgery (TLM). The aim of this study was to analyze both oncological and functional results of TLM in supraglottic cancer. We studied 49 consecutive patients with a primary supraglottic carcinoma who underwent a TLM between the years 1999 and 2009. Nineteen patients were classified as stage I–II and 30 as stage III–IV disease. Forty-five patients underwent also neck dissection. Thirteen patients received postoperative radiotherapy. The minimum follow-up was 24?months. Three- and five-year disease-specific survival rate was 93.2 and 82.2?%, respectively. Of the patients, 36.7?% had some complication after surgery, aspiration being the most frequent (16.32?%). Of the 43 patients who were alive, 39 (91?%) without evidence of disease 3?years after diagnosis had a functional larynx. Our results suggest that TLM is a safe and effective treatment for supraglottic cancer, with a low morbidity rate and excellent functional results.     

Endoscopic CO<Subscript>2</Subscript> laser-assisted surgery for cricopharyngeal dysfunction

Endoscopic cricopharyngeal myotomy was performed on 29 patients with dysphagia from failed relaxation of the cricopharyngeal muscle. The patient outcome was retrospectively evaluated. The average age at the time of treatment was 62 years (range: 38-81 years), and the mean follow-up was 18 months (range:1-36 months). The procedure was the first to be performed in all except four of the patients. Preoperative and postoperative assessments included videofluoroscopic and flexible endoscopic evaluations of the swallow as well as patients' subjective ratings for dysphagia and aspiration. These investigations and self-assessments were rated from 0 (poor or abnormal) to 4 (good or normal). Surgical procedures were performed under general anesthesia. Using the diverticuloscope, the posterior portion of the cricopharyngeal muscle was exposed and CO2 laser sectioned. The wound was then covered with fibrin glue. Patients were parenterally fed for 72 h. Postoperative videofluoroscopy showed the absence of leakage, and all patients resumed oral intake on day 2. The median self-rating score improved from 1 to 4 for dysphagia and from 3 to 4 for aspiration. The outcome of the flexible endoscopic evaluation of swallow improved from 2 to 4 and videofluoroscopy improved from 2 to 4. No surgical complication occurred. Endoscopic CO2 laser-assisted surgery is an effective and safe alternative for the treatment of cricopharyngeal dysmotility.     

New computer-guided scanner for improving CO<Subscript>2</Subscript> laser-assisted microincision

The objective was to clinically test a new computer-guided scanner designed for CO₂ laser-assisted microincision. The scanner-assisted beam travels across the target as a straight or curved incision line. Line length and beam penetration can be adjusted. The studied population, 155 cases, encompassed benign lesions as well as early cancers of the larynx. Operating time was compared with that required for similar operations performed with the Acuspot micromanipulator. Laser-produced coagulation thickness at the incision was measured on 41 operative specimens. The scanner-assisted incision and dissection were more accurate and required up to 30% less time than with a manually guided beam. Postoperative follow-up was straightforward. The coagulation thickness was less than 10 µm for phonomicrosurgery and less than 20 µm for other surgical procedures. The scanner-assisted incision is more accurate than that attained manually.     

Laryngeal solitary fibrous tumor treated with CO<Subscript>2</Subscript> laser excision: case report

The solitary fibrous tumor is an uncommon unilateral benign lesion that usually arises from the pleura. Recently, these tumors have been described in many other locations, such as the mediastinum, head and neck, orbit and urogenital system. To date, only two cases of solitary fibrous tumor arising from the larynx have been reported in the scientific literature. We describe a new case of laryngeal solitary fibrous tumor localized at the right false vocal fold. A 29-year-old man presented with a 6-month history of progressive hoarseness and foreign body sensation in the throat. A mass lesion was recognized in the right false vocal fold, and CT scan demonstrated a large, well-defined tumor without signs of infiltration. The tumor was removed by transoral CO₂ laser surgery. The definitive diagnosis was obtained by immunohistochemical analysis that showed vimentin and CD34-positive cells. The patient remains free of tumor after 15 months of follow-up.     

The role of the CO<Subscript>2</Subscript> laser in the management of laryngotracheal stenosis: a survey of 100 cases

Over the last decade, improvement of CO₂ lasers with the microspot and ultrapulse technologies has broadened the indications for endoscopic CO₂-laser resection of benign laryngotracheal stenosis (LTS). This article reviews 100 patients treated solely by endoscopic means for a LTS. There were 47 grade III, 41 grade II and 12 grade I stenoses according to the Myer-Cotton classification. The postoperative results show that the improvement to a nearly normal (>80% luminal size) airway declines from 92% (11/12 patients) for grade I to 46% (19/41 patients) for grade II and 13% (6/47 patients) for grade III stenoses. When compared to open surgery for more severe grades of stenosis (31 grade IV, 66 grade III and 3 grade II stenoses), the results of the endoscopy group is much less favorable: 36% of patients in the endoscopy group versus 76% of patients in the open surgery group were rehabilitated to a normal respiration without exertional dyspnea and 38% versus 5% patients remained tracheotomy dependent. However, if strict selection and therapeutic criteria are respected, a significant number of grade I and II stenoses, and to a lesser degree of grade III stenoses, can be improved to a nearly normal airway by endoscopic means only. The endoscopic treatment is potentially less invasive and risky and only needs a short hospital stay. To try this as a first treatment modality in a selected group of patients is worthwhile, provided that this endoscopic treatment is not repeated a second time, if the stenosis recurs to its initial grade after a primary CO₂-laser treatment. Some guidelines for safe endoscopic treatment modalities with of the CO₂ laser, dilatation and/or stenting are proposed.     

CO<Subscript>2</Subscript> laser treatment of laryngeal stenoses after reconstructive laryngectomies with cricohyoidopexy,cricohyoidoepiglottopexy or tracheohyoidoepiglottopexy

Supracricoid laryngectomy with cricohyoidopexy (CHP) or cricohyoidoepiglottopexy (CHEP) is a conservative laryngeal surgery tailored to T1b-T2-T3 glottic-supraglottic carcinomas. Tracheohyoidopexy (THP) and tracheohyoidoepiglottopexy (THEP) allow a chance of conservative surgery also for selected transglottic carcinomas. These techniques are comprehensively named reconstructive laryngectomies (RLs). Post RL laryngeal stenosis not due to carcinoma persistence or recurrence is an unusual occurrence. The aim of the present study has been to analyse retrospectively and describe the treatment of the cases of laryngeal stenosis after RL, which occurred in Vittorio Veneto Otolaryngological Department in a 6 year period. In the period between 1999 and 2004, 225 patients underwent RL in our Department. In 18 of them (8%) a laryngeal stenosis after RL was diagnosed. The same evidence was shown in 2 patients who underwent RL in other Institutions. All patients underwent CO₂ laser surgical treatment of the laryngeal stenosis. The 14 patients who underwent RL-CHEP, the 5 patients who underwent THEP and the patient who underwent CHP were treated on average with CO₂ laser 1.2 (range 1–2), 4.2 (range 2–7), and 2 times, respectively. Decannulation was possible in all patients but one after CO₂ laser treatment of the stenosis in a mean period of 3.4 months. Laryngeal stenoses after RLs can be successfully treated with CO₂ laser excision with a very limited morbility. The only reasonable contra-indication to CO₂ laser excision could be a cranio-caudal length of the laryngeal stenotic tract longer than 1 cm: in this occurrence diagnosed after THP or THEP, an external surgical approach could be preferred.     

Use of flexible CO<Subscript>2</Subscript> laser fiber in microsurgery for vestibular schwannoma via the middle cranial fossa approach

The aim of this study was to analyze the results of microsurgery in vestibular schwannomas (VS) with assistance of a flexible CO₂ laser fiber (Omniguide^®) using the middle cranial fossa (MCF) approach. For that purpose we performed a prospective non-randomized clinical trial. In 20 consecutive patients suffering from VS and elected for microsurgery via the MCF approach, tumor resection was performed with the aid of the flexible CO₂ laser (“laser group”, LG). Twenty patients with similar tumor volume and pre-operative hearing status out of a cohort of 76 patients previously treated by the same surgeon without laser were used as comparison group (“conventional group”, CG) (matched-pair-technique). Facial weakness (House-Brackmann (HB) 2-4) was seen in early postoperative (p.o.) days in six patients in each group and all recovered completely by 3 months p.o., except one patient with HB 2 in CG. Facial nerve preservation rate (HB 1 + 2) was 100% in both groups. Hearing preservation rate (Gardner/Robertson class 1 + 2 or AAO-HNS A + B, pre- and postoperatively) was 72% in LG and 82% in CG, without significant difference. Overall time from incision to skin suture was 157 min (SD 55.9) in CG and 160 min (SD 39.7) in LG. Tumor preparation time was 23.2 min (SD 19.7) in CG and 36.1 min (SD 33.8) in LG. The use of a handheld flexible CO₂ laser fiber in VS-microsurgery is safe and subjectively facilitates tumor resection especially in “difficult” (e.g., highly vascularized) tumors. However, in this limited prospective trial the excellent functional outcome following conventional microsurgery could not be further improved, nor the surgical time reduced by means of the non-contact laser-tool. Focusing the use of the flexible CO₂ laser on “difficult” tumors may lead to different results in future.     

Endoscopic CO2 laser therapy of selected cases of supraglottic marginal tumors

Endoscopic CO₂ laser intervention can be used as conservation surgery for supraglottic laryngeal carcinomas in carefully selected patients. We analyzed retrospectively our experience in managing patients with early supraglottic carcinomas operated on at the Clinic of Otorhinolaryngology, Szeged, Hungary, during the 10-year period between 1987 and 1997. Conservation surgery was the treatment of choice in 187 patients, but only 23 (12%) were selected for endoscopic CO₂ laser surgery. Laser surgery was indicated predominantly for T1 cancer of the epiglottis (n = 15), but was also performed for T2 cancers (n = 8). Of the 23 supraglottic tumors treated, 16 had no signs of recurrence to date (1.5 to 9 years after surgery) a local control rate of 70%. Six patients with recurrences underwent salvage therapies that included repeated laser excisions (n = 3), radiotherapy (to 60 Gy), horizontal supraglottic laryngectomy and total laryngectomy. One patient was not resectable because of multiple metastases. Our experience with endolaryngeal CO₂ laser excision indicates that it is a reasonable method in selected cases of supraglottic tumors, but one-third of the patients required salvage treatment.

Reliability and efficacy of a new CO<Subscript>2</Subscript> laser hollow fiber: a prospective study of 39 patients

We present the first series of patients treated by transoral laser surgery (TLS) using the new AcuPulse 40WG CO₂ laser with the FiberLase flexible waveguide (CO₂ LWG) (Lumenis, Santa Clara, CA) with the objective to test its reliability and efficacy. Patients older than 18 years, with oral, pharyngo-laryngeal or tracheal benign or premalignant lesions were enrolled after signing an informed consent. This prospective study was conducted between October 2010 and May 2011 in two tertiary care university hospitals. Thirty-nine patients were enrolled in the study. The mean age was 47.9 years (range 18–86 years). There were 21 women and 18 men. Thirteen patients had hypertrophy of lymphoid tissue (palatine and or lingual), nine patients had granulomas, four patients had an exudative glottic lesion, three patients had severe dysplasia (glottic and supraglottic), three patients had leukoplakia, two patients had glottal cysts, two patients had laryngeal papilloma, two patients had bilateral paralysis of the vocal folds and one patient suffered from spasmodic dysphonia. Eighty-two percent of the procedures were performed under general anesthesia with laryngo-tracheal intubation. The CO₂ fiber passed through a handpiece was used with a microscope in the majority of the procedures. The laser delivery mode parameter used was: SuperPulse or Continuous Wave. Power levels were 3–15 Watts (W), continuous delivery. Each procedure utilized one CO₂ fiber which performed adequately throughout the procedure. No complications were noted with the use of this technology. A bipolar cautery was needed to control bleeding in eight procedures; all these procedures were tonsillectomies. The CO₂ LWG is a safe and reliable tool for TLS. It is durable enough to last through the entire surgical procedure without the need for replacement. Its use must be tailored depending on the type and location of the lesion, the CO₂ lasers tissue effects as well as the surgeon’s experience.     

Prognostic significance of surgical margins in transoral CO<Subscript>2</Subscript> laser microsurgery for T1–T4 pharyngo-laryngeal cancers

Histological affected or close margin is an adverse factor in conventional surgery of larynx-hypopharynx cancer. Our objective was to analyze the relevance of the margins in transoral laser microsurgery (TLM). A retrospective study of 357 consecutive patients with cancer of the larynx and hypopharynx (T1-T4) treated with TLM. Three possible margins were considered: tumor free, affected, and uncertain. An affected margin showed marked tumor infiltration. An uncertain margin was defined when the sample was insufficient, when it showed carbonization impeding accurate evaluation, or when tumor cells were less than 2 mm. Margins were free in 254 (71.1%) patients, affected in 64 (17.9%) and uncertain in 39 (10.9%). One hundred and three patients (28.9%) presented tumor relapse. The margins were associated with tumor relapse (P < 0.001), but were not significantly related to the tumor site (P = 0.307), the pT classification (P = 0.183), or the difficulty of surgical exposure (P = 0.427). Distant metastases were found in 4.7% of the patients with free margins, in 7.7% of those with uncertain margins, and in 14.1% with affected margins. These differences were statistically significant (P = 0.028). Tumor involvement of the surgical margin was associated with higher rates of local relapse, distant metastasis and the necessity of salvage surgery, together with a lower specific actuarial survival rate.     

Transoral CO2 laser microsurgery for Tis-T3 supraglottic squamous cell carcinomas

Eighty patients affected by supraglottic cancer were treated by transoral carbon dioxide laser surgery between 1989 and 2006 in two Italian institutions. Patient staging was as follows: 2 pTis, 20 pT1, 38 pT2, and 20 pT3. Simultaneous or 1-month delayed neck dissection (ND) was performed on 27 (34%) patients, unilaterally in 10 and bilaterally in 17. The pN category was as follows: 9 pN0, 6 pN1, 8 pN2b, and 4 pN2c. A total of 16 (20%) patients received complementary radiotherapy (RT) and 5 (6%) were subjected to chemo-RT for persistent tumor after re-excision due to positive margins, multiple lymph nodes, and/or extracapsular spread after ND. The last follow-up was in December 2008. The 5-year overall, disease-specific and disease-free survivals, local control with laser alone, and organ preservation rates calculated by Kaplan–Meier analysis were 84.4, 97.4, 88.3, 96, and 97.2%, respectively. Univariate analysis showed a statistically significant impact on disease-free survival, local control with laser alone, and organ preservation of pT category (p = 0.009, p = 0.01, and p = 0.03, respectively), while pN category and tumor stage negatively influenced disease-free survival (p = 0.007 and p = 0.01, respectively). This series confirms the good overall oncologic outcomes obtained by transoral laser surgery for Tis, T1, T2, and selected T3 supraglottic cancer with minimal pre-epiglottic space involvement.     

Transoral robot-assisted CO2 laser supraglottic laryngectomy: experimental and clinical data

BACKGROUND: Transoral CO2 laser surgery for selected supraglottic tumors results in improved postoperative function and decreased morbidity, with comparable survival to open surgery. Recently, robot-assisted techniques have been reported for the management of supraglottic lesions. There are no reports in the English literature of robotic technology coupled with CO2 laser technology. Our objective was to report the use of such technology. STUDY DESIGN: Experimental resection of the supraglottis in a cadaver and a dog model using a commercially available surgical robot coupled with CO2 laser technology. Initial human experience with such technology is reported. METHODS: With use of a hollow core fiber that allows the transmission of CO2 laser energy linked to the daVinci Surgical Robot, a supraglottic laryngectomy was performed in an edentulous female cadaver. The FK Laryngo-Pharyngoscope was used for exposure. In a second experiment, a supraglottic partial laryngectomy was performed in an 80 pound dog. On the basis of our experimental experience, a CO2 laser robotic-assisted supraglottic laryngectomy was attempted in three patients. RESULTS: Removal of the supraglottic larynx in both a cadaver and canine experimental models was believed to be satisfactory using this technology. Bleeding was easily controlled in the live canine model. A 74-year-old woman with a large supraglottic mass for which she had been offered a total laryngectomy was resected successfully with this technology. The FK Laryngo-Pharyngoscope provided excellent exposure. The patient was able to swallow without difficulty on postoperative day 5. Follow-up endoscopic examination at 1 month showed no evidence of residual laryngeal tumor. Robot-assisted procedures were attempted in two additional patients, but adequate exposure could not be achieved, and more traditional techniques were performed. CONCLUSIONS: The use of the daVinci Surgical robot coupled with CO2 laser technology is feasible, as demonstrated by our experimental and clinical data. Although further development of the robotic technology is required at present, the use of robotics coupled with CO2 laser technology may have important implications in the management of supraglottic laryngeal cancer in the future.     

One-year follow-up results of combined use of CO<Subscript>2</Subscript> laser and cold instrumentation for Reinke’s edema surgery in professional voice users

The purpose of this study was to present our experience with combined use of CO₂ laser and cold instrumentation for Reinke’s edema surgery and to evaluate 1-year follow-up results of the technique in a series of professional voice users. Fifteen patients with Reinke’s edema who underwent microlaryngoscopic surgery were included. Videolaryngostroboscopy, perceptual and acoustic voice analyses were performed before and after surgery. During the 1-year follow-up, no recurrence of Reinke’s edema was encountered. Significant postoperative improvement was obtained in the quality of voice, in terms of GRBAS scores, Fo, jitter, shimmer and NHR. No evidence of laryngeal cancer was found on the histological examinations. Combined use of CO₂ laser and cold instrumentation provides a reliable and safe method for Reinke’s edema surgery, and cessation of smoking, voice rest and control of the laryngopharyngeal reflux contribute to the success of surgery. We consider that the removal of redundant mucosa of the vocal fold reduces the risk of the recurrence of Reinke’s edema and provides better quality of voice. However, it does not imply that our method is superior to others’, but this procedure constitutes an effective treatment of choice for Reinke’s edema patients, including professional voice users.

CO<Subscript>2</Subscript> gas exchange across the human tympanic membrane is not appreciably affected by pathology

Past in vivo studies in humans showed that the tympanic membrane (TM) is permeable to physiological gases. Animal studies show that transTM CO₂ conductance is increased by TM pathology. The objective of the study was to determine if transTM CO₂ exchange in humans is affected by atrophic and sclerotic pathologies. The study used an ear canal (EC) probe (ECP) constructed from a custom-fitted acrylic body, a glass capillary tube enclosing an oil meniscus to maintain ambient ECP + EC pressure and a silica glass microtube linked to a mass spectrometer (MS) for measuring gas composition that was hermetically sealed within the ear canal of the test ear. ECP + EC volume was measured and gas samples taken at 10 min intervals for 1 h. The fractional CO₂ pressure measured in the ECP + EC for each sample was regressed on time and the slope of the function multiplied by the ECP + EC volume and divided by the estimated transTM CO₂ gradient at the start of the experiment to yield transTM CO₂ conductance (μL/min/Pa). Data were complete for 15 normal, 13 sclerotic and 9 atrophic TMs. The average (+std) transTM CO₂ conductances were 1.76 × 10⁻⁴ + 7.27 × 10⁻⁵, 2.26 × 10⁻⁴ + 1.5 × 10⁻⁴ and 2.36 × 10⁻⁴ + 1.14 × 10⁻⁴ μL/min/Pa/TM for the normal, sclerotic and atrophic TMs, respectively. A pairwise comparison of data for the normal and atrophic TMs under the directional hypothesis of a greater CO₂ exchange rate for thinner TMs approached statistical significance (P = 0.07). A similar pairwise comparison for the sclerotic and normal TMs did not approach statistical significance (P = 0.28). The effect of TM pathologies on CO₂ conductance was limited.
