Transoral Tongue Suspension for Obstructive Sleep Apnea-A Preliminary Study.

Objectives: To evaluate the safety and efficacy of a novel technique for transoral tongue suspension (TOTS) in obstructive sleep apnea (OSA) patients. Material and Methods: The retrospective study enrolled 24 consecutive OSA patients (21 males; average age, 43 years; average apnea–hypopnea index (AHI), 42.2 event/h; average body mass index (BMI), 25.7 kg/m2) with tongue obstruction confirmed by drug-induced sleep endoscopy. All patients received TOTS as the main procedure in conjunction with uvulopalatopharyngoplasty (UPPP). Key procedures of TOTS included a transoral sublabial approach, drilling two holes on the mandible, passing the polypropylene through the hole to the tongue base using a suture passer and returning the polypropylene through loop traction, and tying the polypropylene to the mandible. Lingual tonsil ablation (n = 8) was also implemented in hypertrophic lingual tonsils (grades III and IV). Results: The operation time for TOTS was around 30 min. No wound bleeding or airway compromise occurred throughout the postoperative period. Minor complications were temporary and included swelling of the tongue, numbness of the lower incisor, and sublabial wound dehiscence (n = 2). The quality of life improved significantly in the patients’ subjective daytime sleepiness according to the Epworth Sleepiness Scale (11.4 ± 3.2 vs. 5.7 ± 1.6, p < 0.001). The objective parameters of OSA also improved significantly in the apnea/hypopnea index (42.2 ± 21.8 vs. 19.5 ± 16.2, p < 0.001), minimal oxygen saturation (77.1 ± 12.2 vs. 81.7 ± 8.1, p = 0.026), and snoring index (207 ± 141 vs. 101 ± 91, p = 0.03). Conclusions: The demonstrated TOTS showed its advantage in low morbidity with a scarless exterior and easy performance with free availability in treating adult OSA patients with tongue obstruction. TOTS combined with UPPP significantly improved AHI and daytime sleepiness. TOTS can be implemented with lingual tonsillectomy to achieve both stabilization of the tongue and widening of hypopharyngeal airway.

Glossopharyngeal Neuralgia and Somatic Tinnitus Caused by a Small Tonsillolith

A 66 years old male presented with severe right-sided otalgia and throat pain, which persisted more than a year. He also complained of bilateral tinnitus. Tinnitus was continuous and high-pitched. Severe pain usually followed swallowing food. Pressing his right tonsil aggravated such symptoms. Pure tone audiogram showed both high frequencies hearing loss. Neck CT image revealed a small tonsillolith in his right tonsil. Gabapentin and non-steroidal anti-inflammatory drugs reduced the intensity of pain, but could not eradicate the pain. Finally, we performed radiofrequency tonsil ablation to eliminate right side tonsillolith. After ablation, pain immediately subsided and his tinnitus also disappeared. Tiny impacted tonsillolith may induce glossopharyngeal neuralgia and somatic tinnitus.

Effects of low-temperature plasma treatment on pulmonary function in children with obstructive sleep apnea-hypopnea syndrome.

Obstructive sleep apnea-hypopnea syndrome (OSAHS) is a common sleep-related respiratory disease. Despite reports of low-temperature plasma radiofrequency ablation of tonsils and adenoids for the treatment of OSAHS, the effects on lung function and quality of life are unclear. This study aims to explore the effects of low-temperature plasma treatment on pulmonary function in children with OSAHS. A total of 110 children with OSAHS were included in this prospective study. Low-temperature plasma radiofrequency treatment and routine surgical treatment were performed in group A and group B, respectively. Maximal voluntary ventilation (MVV), forced vital capacity (FVC), and total lung capacity (TLC) were measured. OSA-18 survey was used to evaluate the quality of life 1 year after operation. Group A had significantly higher effective treatment rate (P < 0.05) and lower operative period, bleeding volume, visual analog score, pseudomembrane detachment time, and time required to feed after operation than group B (all P < 0.001). There were no significant difference in the incidence of postoperative complications between the groups and MVV, FVC, and TLC between the groups before and after operation (all P > 0.05), and the above indexes in both groups were significantly increased after operation (all P < 0.05). OSA-18 scores in group A were significantly lower than group B after operation (P < 0.001). Low-temperature plasma technique performed in OSAHS children has a good clinical effect, which can reduce the operation time, intraoperative blood loss, postoperative pain, pseudomembrane detachment time, hospitalization time, and improve pulmonary function and quality of life.

Features of thermal effect at high-frequency laser impact on biological tissue (experiment). Technique of laser ablation of a pharyngeal tonsil

In the conditions of the experiment the peculiarities of thermal influence of Ho:YAG on biological tissue in the ablation mode were studied. In the experiment we used: surgical laser system LUMENIS VersaPulse PowerSuite 20, universal thermal imaging camera FLIR SC7000. The biological object (turkey meat) was remotely, at a distance of 5 mm, affected by a Holmium laser (E = 0.9 J and R = 12 Hz) for 6 seconds. The maximum temperature (Tmax, °C) in the ablation zone was measured in real time. As a result, it was found that laser ablation of a biological object is characterized by thermal effects, which largely depend on the state of irradiated tissue: the temperature of the irradiated object rises to critical values equal to 100.07-111.24 ° C, after which the surface layer of biological tissue is charred, and the process of laser "removal" stops; intact biological tissue reaches critical heating after 3.48 s, while under the influence of a high-frequency laser on the previously irradiated biological tissue development period It was also established that in order to continue laser ablation with controlled thermal effect it is necessary to remove charred areas of biological object. On the basis of the obtained data the method of laser ablation of pharyngeal tonsils was developed.

Surgical ablation of lingual tonsils in the treatment of obstructive sleep apnea

Objectives/HypothesisThe retrolingual space is one of the potential sites of obstruction identified in patients with obstructive sleep apnea syndrome (OSAS). Hypertrophied lingual tonsils (LT) can obstruct the airway at this level. The goal of this study was to measure the tolerance and efficacy of lingual tonsillectomy in patients with OSAS. Study designA retrospective chart review was conducted recruiting all patients with OSAS confirmed on sleep recording, who either had failed or refused medical treatment and who underwent lingual tonsillectomy. Materials and methodsDiagnosis of LT hypertrophy was made by full ENT clinical examination using a flexible endoscopy, completed by MRI and followed by drug-induced sleep endoscopy. The surgical intervention was carried out endoscopically by diode laser or coblation. The primary endpoint to measure efficacy was drop in apnea-hypopnea index (AHI) on sleep recording at 6 months. Secondary endpoints comprised reduced snoring and Epworth Sleepiness Scale (ESS) and postoperative symptom tolerance. ResultsEleven patients aged 44.3±12.6 years were included. AHI dropped from 29.5±21.7/h to 11.6±9.6/h: i.e., by 60% (P=0.005). Five patients had AHI<10/h: i.e., cure rate of 45%. ESS dropped from 13±3.4 to 8.1±4.9 (P=0.012). No complications were observed. ConclusionsLT ablation seemed effective in OSAS with retrolingual obstruction in failure of medical treatment. Level of evidence4.

Cold Dissection Tonsillectomy and Radiofrequency Tonsil Ablation: A Prospective Comparative Study

Background: Over the last few years, various techniques have been proposed for performing tonsillectomy in an attempt to lower the morbidity of this surgery. However, controversy still exists regarding the optimal technique involving the least postoperative morbidity. More recently, temperature-controlled radiofrequency has been introduced as a much more effective and safe device for tonsil reduction. Objective: To compare the effectiveness of conventional tonsillectomy versus radiofrequency tonsil ablation with respect to duration of surgery, amount of intraoperative bleeding, recovery time, and postsurgical pain. Materials and Methods: 60 patients were randomly divided into two groups. One group underwent conventional cold ablation tonsillectomy while radiofrequency tonsillectomy was performed in the second group. Duration of surgery, amount of intraoperative bleeding, recovery time, and postsurgical pain (using the Wong-Baker FACES Pain Rating Scale®) were measured. All patients were followed for 24 months. Results: Comparing the radiofrequency tonsillectomy group to the cold dissection tonsillectomy group, the mean duration of surgery was 6.92 versus 18 min, the amount of intraoperative bleeding was 2.75 versus 39.88 mL, and the difference on the postoperative pain scale between the two groups was statistically significant (p < 0.005). There was no recurrence of tonsillitis episodes in either of the 2 groups during the 2-year follow-up period. Conclusion: After adequate training, the radiofrequency technique is beneficial to both the surgeon and the patient, including the possibility to excise tissue and coagulate bleeding vessels with the same device. Postoperative morbidity and complications are lower as compared to the conventional cold dissection technique.

Comparing the Efficacy of Temperature-Controlled Radiofrequency Tonsil Ablation versus CO2-Laser Cryptolysis in the Treatment of Halitosis.

Halitosis and foreign body sensation are two common and disturbing symptoms of chronic caseous tonsillitis (CCT). The aim of this study was to compare the efficacy and safety of temperature-controlled radiofrequency (TC-RF) tonsil ablation with CO2-laser cryptolysis (CO2-LC) in the treatment of patients with halitosis caused by CCT. Sixty-two patients who suffered from halitosis and/or foreign body sensation due to CCT were enrolled in the present randomized clinical trial, and were randomly assigned into two groups. Group A underwent TC-RF tonsil ablation and Group B received CO2-LC. The severity of symptoms including halitosis and foreign body sensation was reported 7 days, 1 month, and 6 months after the procedure. Patient pain levels and amount of bleeding were evaluated as safety outcome measures. Pain levels were evaluated during the intervention, and at Day 1, 3, and 7 following the procedure using a visual analog scale (VAS). Mean rank of pain score in the RF tonsil ablation group was found to be higher than in the CO2-LC group at all measured timepoints following the procedure. The amount of bleeding in the LC group was found to be significantly less than in the RF group (P<0.05). No significant difference was found between the groups regarding duration of procedure (P=0.157). Both procedures were found to be effective and safe in the treatment of CT-associated halitosis. However, LC showed better results based on lower pain levels, lower incidence of bleeding, and faster progression to a routine diet.

An update on tonsillotomy studies

Tonsillotomy procedures (TT) are being increasingly performed owing to the low postoperative morbidity compared with extracapsular tonsillectomy (TE). Patients may experience regrowth of tonsillar tissue or tonsillitis in the tonsillar remnants eventually resulting in asecondary tonsillectomy. A review of the literature was undertaken to evaluate the current indications and contraindications, surgical instruments, risks of surgery, and the need for further research related to TT. A search of the PubMed database was performed with the following terms: "tonsillotomy," "partial tonsillectomy," "subtotal tonsillectomy," "intracapsular tonsillectomy," "RFITT," and "tonsil ablation." Filters included language (English; German) and publication date (1960-2016). Articles were excluded if they were not related to tonsil surgery, did not provide clinical data, dealt with uncommon surgical techniques, or presented only data from polysomnographic studies. In all, 104 papers encompassing 97studies and sevennational surveys were eligible for analysis. In total, 13,270 patients had undergone TT and were compared with 11,485 patients after TE. Partial resection of the tonsils was most commonly accomplished with amicrodebrider (51.5 %), and less frequently with coblation (20.5 %), radiofrequency (9.1 %), CO2 laser (6.6 %), or other surgical instruments. The age in the study groups ranged between 6months and 78years (median: 6.0years). The prevailing indication for surgery was upper airway obstruction resulting from tonsillar hyperplasia with (n= 20) or without (n= 60) ahistory of tonsillits. In sevenstudies, TT was explicitly performed to resolve tonsillitis, while threeauthors did not specify the indication for surgery. The hemorrhage rate after TT was 0.2 % on average. TT is predominantly indicated for tonsillar hyperplasia, with or without tonsillitis. Restrictions related to age or surgical instruments are not reported in the literature data. Data concerning operation time, intraoperative bleeding, and outcome favor TT over TE. The median values for regrowth (3.0 %), postoperative tonsillitis (2.85 %), and secondary TE (1.37 %) emphasize thehigh success rate of TT. Further research utilizing auniform terminology is mandatory to clarify the benefit of TT over TE in the long term and to resolve sleep-related breathing disorders resulting from tonsillar hyperplasia or tonsillitis.

A Rare Complication of Radiofrequency Tonsil Ablation: Horner Syndrome.

Chronic tonsillitis is a common disease, and several different surgical techniques are used to treat this condition. In recent years, techniques such as radiofrequency ablation and coblation have been commonly used for tonsil surgery. In this report, we present the cases of two pediatric patients who developed ptosis, miosis, and enophthalmos (Horner syndrome) after radiofrequency ablation for tonsil reduction and discuss the technique of radiofrequency ablation of the tonsils. In the early postoperative period, miosis and ptosis were observed on the right side in one patient and on the left side in the other patient. Both patients were treated with 1 mg/kg/day methylprednisolone, which were tapered by halving the dose every 3 days. Miosis and ptosis improved after treatment in both patients. Along with the case presentation, we discuss the effectiveness and complications of radiofrequency ablation of the tonsils. These unusual complications of tonsil ablation may help ENT physicians who do not yet have a preferred surgical technique for tonsillectomy to make an informed decision. Limited data are available about the possible complications of radiofrequency ablation of the tonsils. The present report contributes to the literature on this topic.

Tonsillotomy: facts and fiction

In contrast to total or extracapsular tonsillectomy (TE), subtotal/intracapsular/partial tonsillectomy (SIPT) or tonsillotomy (TT) is associated with significant less postoperative morbidity. It has been stated that patients older than 8years of age or with a history of tonsillitis should be excluded from SIPT/TT. Some health insurance companies mandate utilization of particular surgical instruments. Finally, it has been stated that the remaining tonsillar tissue may become a subject of recurrent tonsillitis or tonsillar regrowth, in both cases requiring revision surgery in terms of TE. This literature review was undertaken to clarify what has been validated in the literature concerning indications, surgical techniques, complications and outcome of SIPT/TT as reported since 1960. A Medline review was undertaken and all papers included that were published in English or German language until September 30, 2013. Exclusion criteria were: publication date 1960 and earlier, other languages, no relation to tonsil surgery, papers not available to the authors, uncommon surgical techniques, national surveys or studies without patients. The quality of the papers was classified according to "The Oxford 2011 Levels of Evidence". The surgical techniques were classified according to Windfuhr and Werner and extended to interstitial tonsil therapy. Other issues were: study period, hemorrhage, dehydration, intake of analgesics, return to normal diet, surgical instruments, operation time, number of surgeons involved, number of patients, age, indications, follow-up, rate of tonsillar regrowth, tonsillitis and secondary TE. A total of 379 different publications were retrieved, but only 86 studies found eligible for further analysis. There were 10,499 patients in the study groups and 10,448 patients in the control groups. Utilization of the microdebrider largely prevailed, followed by Coblation, CO2-LASER, surgical scissor, Radiofrequency, Interstitial ThermoTherapy with various instruments, Diode-LASER, and other instruments. Instruments were not specified for 1,815 patients. Data for operation time, intraoperative bleeding, return to normal diet, analgesic intake were in favor for SIPT/TT and ablation procedures. Regrowth and tonsillitis occurred in rates of <6% on average. Secondary surgery became necessary in only every third patient of this subgroup. Studies of variable quality impede comparison of all aspects in the papers. At least every second study did not address issues like operation time, intraoperative bleeding, return to normal diet, analgesic intake, rates of tonsillar regrowth, postsurgical tonsillitis and secondary TE. There are insufficient data to show that a single surgical instrument is superior. A history of tonsillitis and an age >8years are definitely not commonly accepted as contraindication for SIPT, TT or ablation procedures. There is a strong evidence that pain is less after SIPT, TT and tonsil ablation resulting in an earlier return to normal diet and activity. Large, well-designed randomized controlled trials with an adequate follow-up are necessary to determine whether the procedure is capable to replace TE to resolve upper airway obstruction resulting from tonsillar hypertrophy as well as recurrent episodes of tonsillitis in children and adults.

The effect of radiofrequency ablation on microbiology of the tonsils

ObjectiveTo investigate the effect of tonsil size reduction using temperature controlled radiofrequency on the number of pathogenic bacteria in the tonsil tissue. Materials and methodsThis study was performed on 25 patients who had undergone tonsillectomy under general anesthesia at our clinic. Immediately after the cold knife tonsillectomy both tonsils were removed, one was included in the control and the other one was included in the study group. In vitro radiofrequency was applied to the tonsil in the study group at eight distinct points, each lasting 15s. Biopsy materials were taken under sterile conditions from the center of each tonsil for further culturing. ResultsThe difference in bacterial number was investigated between the two groups. The bacterial number following radiofrequency administration was found to be significantly very lower compared to the control group (p<0.01). Radiofrequency administration significantly reduced growth of all types of bacteria. ConclusionThe radiofrequency tonsil ablation technique, which is used safely and effectively in the management of obstructive tonsil hypertrophy, currently has no indication for the treatment of patients with chronic and recurrent tonsillitis. However, when the right conditions are provided, the radiofrequency tonsil ablation technique may be applied to patients with chronic and recurrent tonsillitis and further studies investigating the differences in the frequency of patients’ tonsillitis episodes should be undertaken.

The “Swiss-cheese Doppler-guided laser tonsillectomy”: a new safe cribriform approach to intracapsular tonsillectomy

Outpatient laser ablation of palatine tonsils is a very interesting procedure that has been recently introduced as a routine in head and neck surgery departments. The aim of this study was to describe a new strategy using a Doppler-guided fibre optic neodymium-yttrium–aluminium–garnet (YAG) laser to remove up to 80 % of tonsillar tissue, as assessed in the long-term postoperative clinical evaluation of the volume of the tonsils at the follow-up, and leaving the capsule in place, thus avoiding any haemorrhagic complication and minimize pain. A total of 20 patients (men, n = 13; women, n = 7), aged between 6 and 63, were recruited for the procedure. They were affected by chronic hypertrophic tonsillitis with a recurrent fever and other symptoms that were related to oral inflammation. Among the 20 patients, no serious adverse events, including haemorrhage-related complications, were observed. Treatment was well tolerated, even in patients displaying an overall low pain threshold. No dropout or uncompleted procedure occurred in the present study. Minor complications included sore throat, moderate oedema, mild acute pharynx inflammation, slight peritonsillar exudate and local burning. The postoperative pain, measured by Scott–Huskisson visual analogue scale, was between 5 and 40 mm and was easily counteracted by means of external ice packages and nonsteroidal anti-inflammatory drugs, according to the individual patient’s need. During the 12–36-month follow-up patients showed improved symptoms (n = 7) and complete recovery (n = 13). A relapse episode was observed in two patients. This study supports fibre optic laser neodymium-YAG tonsil surgery, named “cribriform intracapsular tonsillectomy” or “Swiss-cheese laser tonsillectomy”, as an effective alternative to the traditional cold knife approach or electrosurgery. This approach could become the gold standard for tonsil surgery in the third millennium for safety reasons, acceptable cost–benefit ratio, the precise targeting of the beam across the affected tissues and the short- and long-term recovery.

Adenotonsillar Disease

Adenotonsillar disease (adenoiditis and recurrent tonsillitis) is a prevalent otolaryngologic disorder aetiologically based on chronic inflammation triggered by a persistent bacterial infection. These bacteria, mostly Staphylococcus aureus, Haemophilus sp., and Streptococcus sp., persist predominantly intracellular and within mucosal biofilms. The recurrent or chronic inflammation of the adenoids and faucial tonsils leads to chronic activation of the cell-mediated and humoral immune response, resulting in hypertrophy of the lymphoid tonsillar tissue. This hypertrophic tissue is the cause for the prominent clinical symptoms: obstruction of the upper airways, snoring, and sleep apnea for adenoiditis or sore throat, dysphagia and halitosis for recurrent tonsillitis. Treatment strategies should target the persisting bacteria within their biofilm or intracellular shelter. Macrolide antibiotics like clarithromycin are able to modulate the immune system and to interfere in bacterial signaling within biofilms. Clindamycin, quinupristin-dalfopristin, and oritavancin are intracellular high active compounds. Surgical removal of the hypertrophic tissue by modern procedures like laser tonsil ablation, eliminates not only a mechanical obstacle of the airways, it removes also the basis for the aetiologic cause, the "biofilm carrier". This review summarizes the role of bacterial persistence in mucosal biofilms for the aetiology, diagnosis and treatment of adenotonsillar disease and relevant patents.

Lingual tonsils hypertrophy; a cause of obstructive sleep apnea in children after adenotonsillectomy: Operative problems and management

Objective Although adenotonsillar hypertrophy has been reported to be the commonest cause of pediatric obstructive sleep apnea (OSA), enlargement of the lingual tonsils is increasingly being recognized as a cause, even after adenotonsillectomy. The aim of our study was to elucidate the lingual tonsils hypertrophy as a cause of pediatric OSA and also to evaluate the efficacy of lingual tonsillectomy in relieving symptoms of the disease considering the peri-operative problems and management. Methods Sixteen children with lingual tonsils hypertrophy after adenotonsillectomy were included in the study. Computerized tomography (CT) and/or magnetic resonance imaging (MRI) were used for detection of the lesions. They underwent lingual tonsillectomy with special anesthetic care, flexible laryngoscopy and polysomnography were done pre- and post-operatively. Follow up of the patients was carried out for at least 1 year. Results Three cases developed post-operative airway obstruction that is caused by tongue base edema. Complete improvement of snoring and apnea was achieved in 10 cases. Despite complete ablation of lingual tonsils, persistent snoring was detected in six cases, while apnea was detected in two cases. Down's syndrome, mucopolysaccharidoses, and obesity may be underlying factors for persistent symptoms. Conclusions Lingual tonsils hypertrophy could be the cause of obstructive sleep apnea in children after adenotonsillectomy, lingual tonsillectomy is an effective treatment for these cases, however peri-operative airway problems should be expected and can be managed safely. Persistent symptoms after lingual tonsillectomy may be due to the presence of co-morbidities such as cranio-facial deformities, obesity, and/or mucopolysaccharidoses.

Temperature-controlled radiofrequency tonsil ablation for the treatment of halitosis

The objective of the study was to evaluate the efficacy and safety of temperature-controlled radiofrequency (RF) tonsil ablation in the treatment of halitosis caused by chronic tonsillitis with caseum. The study method was retrospective. The medical records of 58 patients undergoing temperature-controlled RF tonsil ablation due to chronic tonsillitis with caseum between November 1, 2005 and November 30, 2008 were reviewed. Forty-nine (84.4%) of 58 patients reported complete disappearance of bad breath after the first treatment; five patients (8.6%) reported as having insufficient improvement and four (6.9%) patients had no change. Two patients from "insufficient group" and all four patients from "no change" group agreed to a repeat treatment. After the second session, four (6.9%) patients reported complete disappearance of halitosis with the disappearance of caseum formation. But two patients still suffered from halitosis. One of these patients underwent tonsillectomy, other patient is under our follow-up. Overall, complete elimination of halitosis was accomplished with one session in 49 (84.4%) patients, two sessions in four (6.9%) patients, making a total of 53 (91.3%) patients. Postoperative morbidities included one transient mild bleeding, one secondary bleeding and one mild edema. Temperature-controlled RF tonsil ablation is an effective method for treating halitosis which derived from chronic tonsillitis with caseum. This well-tolerated technique avoids the post-procedure morbidities and discomfort of more invasive surgical modalities currently used.

Volumenreduktion bei Tonsillenhyperplasie im Kindesalter durch ein operatives Ultraschallsystem

We present the results of a prospective study concerning the use of a surgical-ultrasound device (use of ultrasound mechanical vibrations in the tonsil tissue with denaturizing effect on collagen and proteins for tonsil ablation, coablation) for the therapy of non-infectious tonsillar hyperplasia resulting in upper airway obstruction in childhood. 51 patients with a median age of 6.9 years (3.5-12 years) were treated with surgical ultrasound, under general anesthesia. The intervention did not include tissue excision, but the denaturation of hyperplastic tonsil tissue. Intra- and postoperative bleeding, pain (by visual analog scale), tonsil-to-tonsil diameter and swallowing difficulties were under consideration. Also an bacteriological examination of tonsils was performed. The procedure was generally well tolerated. There was no intra- or postoperative bleeding. Swallowing difficulties were described as not very disturbing. Median follow up was 2.1 years. The postoperative "wound healing" lasted 7-9 days. A reduction of tonsil's size was visible since the first post treatment week with the final results occurring after 3-6 months. Intertonsillar distance was 9 mm preoperatively and 22.14 mm after coablation. A higher incidence of bacterial tonsillitis or development of quinsies were not reported. The treatment of tonsilar hyperplasia by means of surgical ultrasound is highly effective and causes relatively mild post surgical complaints without intra- or postoperative bleeding.

Tonsillectomy

Tonsillectomy

CO2 laser for lingual tonsillectomy

Objectives: Hypertropic lingual tonsils are a known obstruction in the upper airway. Enlarged linguals are responsible for obstructive sleep apnea, potential infections, and difficult intubations for routine surgeries. In our institution all patients were treated with protection of the airway, and ablation of lingual tonsils with a CO 2 laser. Methods: The patients were diagnosed with direct visualization and a CT scan of the neck. All patients were intubated with a laser reinforced endotracheal tube and fire precautions were taken when draping patient. One patient had a tracheotmy performed before being treated for hypertrophic lingual tonsils. A wide funnell larynscope was suspended. The CO 2 laser was used at 15 watts continuous along with an operating microscope to ablate the tissue. Results: All patients were admitted for a 23-hour stay. Postoperatively, no patient required intubation to protect the airway. Three of the 50 patients required a revision surgery to completely ablate all the lingual tonsils. The patient with the tracheotomy was decannulated. All patients were relieved and asymptomatic after surgery. Conclusion: CO 2 laser is a safe and acceptable method for lingual tonsillectomy. All patients in our institution had no complications and were free of all symptoms. The laser compleletly ablated the lingual tonsils removing the obstruction in the airway.
