Randomized study comparing two tongue base surgeries for moderate to severe obstructive sleep apnea syndrome

2009

To compare the effectiveness and morbidity of the tongue base radiofrequency and tongue base suspension techniques combined with uvulopalatopharyngoplasty for moderate to severe obstructive sleep apnea.Prospective and randomized surgical trial at a university hospital.In total, 57 patients received either tongue base radiofrequency reduction (n = 29) or tongue base suspension (n = 28). Apnea-hypopnea index, lowest oxygen saturation (polysomnography), Epworth score, and side effects were assessed. Success was defined as aor =50 percent reduction and final apneahypopnea index15/h, and an Epworth score11.The success rates of the two procedures were 57.1 percent and 51.7 percent, respectively (…

A Passive-Marker-Based Optical System for Computer-Aided Surgery in Otorhinolaryngology: Development and First Clinical Experiences

1999

Objectives: To develop a new type of optical computer-aided surgery (CAS) device that overcomes some of the restrictions of common systems and to examine its accuracy and usability under laboratory and intraoperative conditions. Study Design: Prospective study using laboratory experiments and intraoperative data collection. Methods: An optical CAS system applying passive optical markers for coordinate determination was developed. Laboratory accuracy measurements were obtained on a Plexiglas model with known coordinates of fiducial markers, before and after predefined table movements. Intraoperative accuracy measurements were recorded from 24 patients undergoing endonasal surgery of the para…

Characteristics of recurrent chronic rhinosinusitis after previous surgical therapy.

2008

Our findings emphasize the role of a thorough diagnostic evaluation preoperatively and a targeted long-term medical therapy following any sinonasal surgery for inflammatory disease. Early onset of long-term aspirin desensitization can address a very predominant inflammatory stimulus in a large number of our patients in an effort to prevent recurrent chronic rhinosinusitis (CRS) after successful surgical therapy.Postoperative recurrence of CRS, regardless of the ongoing evolution of diagnostic and surgical techniques, still poses an unsolved problem.This investigation was designed to further characterize the role of aspirin intolerance (AI) and inhalant allergies as persistent inflammatory s…

Anatomic Changes After Hyoid Suspension for Obstructive Sleep Apnea: An MRI Study

2005

Objective To assess the effects of isolated hyoid suspension on subjective and objective parameters of obstructive sleep apnea and to evaluate changes in upper airway anatomy with the help of standardized magnetic resonance imaging. Study design and setting Fifteen patients received isolated hyoid suspension. Changes in respiratory disturbance index were assessed with polysomnography, and anatomical changes with standardized magnetic resonance imaging. Snoring, daytime sleepiness, and functional parameters were assessed with questionnaires. Lateral x-ray cephalometry was performed preoperatively. Results Mean respiratory disturbance index was reduced from 35.2 ± 19.1 to 27.4 ± 26.2. Forty p…

Multilevel temperature-controlled radiofrequency therapy of soft palate, base of tongue, and tonsils in adults with obstructive sleep apnea.

2003

Objectives/hypothesis The concept of two-level pharyngeal collapse in patients with obstructive sleep apnea is too simplified. Aggressive multilevel surgeries addressing several airway segments, including skeletal surgery, demonstrate improved success rates. Study design The study aimed to evaluate the safety and efficacy of multilevel radiofrequency application to soft palate, tonsils, and base of tongue in 16 white patients (mean age, 56.9 +/- 11.1 y; mean body mass index, 27.3 +/- 2.6 kg/m2) with obstructive sleep apnea. There was one dropout. Therapeutic effects after one treatment session were assessed 20.6 +/- 12.6 weeks postoperatively. Treatment outcome measurements were based on Ep…

Endoscope‐microscope combination for endonasal sinus surgery

Treatment of bilateral vocal cord paralysis following permanent recurrent laryngeal nerve injury.

2012

Bilateral vocal cord paralysis is a serious illness requiring emergency intervention to resolve the potentially life-threatening respiratory distress. Several surgical procedures were proposed to help improve the airway and to eliminate the tracheostoma in those patients with permanent paralysis. All the procedures have their own advantages and disadvantages. We conducted a retrospective study of 30 patients affected by bilateral vocal cord paralysis following total thyroidectomy. All the patients underwent total thyroidectomy for benign thyroid pathology. In 26 patients (86.6%), cord paralysis occurred during the perioperative stage; and in the remaining 4 cases (13.3%), it occurred within…

ELS live surgery: a developing story

2019

Since 2015, the European Laryngological Society (ELS) has organized on a yearly basis the European Laryngological Live Surgery Broadcast. The goal of this paper is to demonstrate the increasing worldwide audience. The number of individual computers logged in, number of estimated audience, and number of countries with an active audience were calculated and compared to the numbers in 2015. In 2018, 19 live interventions were performed in three parallel sessions. The surgeons worked in 10 departments in 8 different countries. The number of individual computers logged in increased from 1000 in 2015 to 16000 in 2018. The estimated audience increased from 3000 to 32000 visitors. The number of cou…
