Apport de la piézochirurgie pour l’avancée des géniotubercules dans le syndrome d’apnées obstructives du sommeil

The tongue is a frequent cause of upper airway obstruction in obstructive sleep apnea syndrome. The genioglossi muscles are the front-most muscles of the tongue, attached to the geniotubercle on the inner cortical of the mandibular symphisis. The collapsibility of the tongue can be managed with genioglossus advancement. Piezo surgery can decrease the risk of apical dental lesion. The perfect depth control during osteotomy and absence of soft tissue lesion considerably limit the risks of oral floor lesion.
