    Abstract:
    We present preliminary results and indications of tongue base reduction with hyo-epiglottoplasty for the treatment of severe obstructive sleep apnea syndrome (OSAS) due to isolated hyolingual abnormalities. The procedure consists in a subtotal resection of the tongue base after identification and derouting of the lingual neurovascular bundle. Hypopharyngeal enlargement, epiglottis verticalization, floor of the mouth tension and hyoid bone repositioning are also performed during the procedure. 14 severe OSAS male patients (mean apnea-hypopnea index of 71) were treated in our institution from November 1992 to February 1996. Indications were determined after a cephalometric analysis and a magnetic resonance imaging evaluation. Results were evaluated on clinical and polysomnographic criteria. No neurovascular complications occurred. Clinical results were excellent but success rate based on polysomnography was 50%. These preliminary results led us to change some of the steps in the technique. We also identified a predictive factor of success on the cephalometrics: an oropharyngeal area greater than 25 cm2.
