Abstract

We describe a modified technique for mortised genioglossus advancement for treating obstructive sleep apnea and review the history of osteotomies in this region. This new osteotomy technique allows for greater soft tissue advancement of the hypopharyngeal region. Anatomical data from a previous study were used to evaluate the dimensions of the anterior mandible and design an osteotomy that overcomes shortcomings of previous designs. These anatomic measurements enabled us to estimate the size and formulate a design utilized in the anterior mandible for the treatment of obstructive sleep apnea. We believe this design offers the greatest amount of muscular advancement by including genioglossus, geniohyoid, digastric, and mylohyoid. This advancement results in increasing the posterior airway space by volumetric expansion. Custom-designed fixation was utilized to increase stability laterally and decrease the risk of mandibular fracture. The design should be a significant aid in reconstruction of the hypopharyngeal airway in patients with obstructive sleep apnea.
