Obstructive sleep apnea is the most common type of sleep apnea that results from obstruction of the upper airway.Untreated OSAS can cause various problems such as hypertension,diabetes,stroke,cardiac disease,daytime sleepiness.It has been demonstrated that genioglossus advancement is an effective procedure for the improvement of the upper airway in some of OSA patients.The purpose of this paper is to introduce a simple and atraumatic technique for the advancement of the genioglossus muscle.We performed new method that uses a specially designed drills and plate.In postoperative radiograph,the lower pharynx was enlarged 8.7–20.2mm with the advancement of genial tubercle by 12.7 mm.The technique is more simple,atraumatic,and cost-effective than traditional techniques for genioglossal advancement.It helps surgeons to do such operations efficiently and quickly,and can minimize the patients discomfort.We hope that it will reduce the incidence of post-operative complications such as bleeding,pain,and swelling.
