Objective: To determine whether the retrolingual pharynx shows the same morphometric modifications during the Muller manoeuvre and during drug-induced sleep endoscopy (DISE) with propofol in patients submitted for maxillomandibular advancement surgery.
Subjects And Methods: Eighteen patients submitted for maxillomandibular advancement surgery (MMAS) were evaluated endoscopically before and 6 month after surgery in the region of the retrolingual pharynx while seated and lying in dorsal decubitus (supine) while performing the Muller manoeuvre and during DISE with propofol, to verify and measure if the same morphometric changes occur in the retrolingual pharynx during the Muller manoeuvre and during DISE with propofol. The area, anteroposterior, and laterolateral retrolingual pharynx images were acquired using the Sony Vegas 8.
Introduction: Maxillomandibular advancement (MMA) has been reported to be the most effective surgical treatment of obstructive sleep apnea (OSA). Most reports about MMA aim to confirm the efficiency of this treatment modality, but few describe the anatomical changes produced in the pharynx by the surgery. Thus, the objective of the present investigation was to quantify the anatomical changes of the pharynx that occur in patients with OSA after MMA surgery using magnetic resonance (MR).

Materials And Methods: Eighteen patients with mild to severe grade obstructive sleep apnea hypopnea were evaluated during wakefulness while sitting and lying down and during induced sleep in dorsal decubitus while breathing naturally. Images of the retrolingual region of the pharynx were captured with a nasofibroscope and recorded on a DVD using the Sony Vegas 8.
