Nasal and maxillary sinus volume change in patients with obstructive sleep apnea after bimaxillary advancement surgery.

The airway complex is modified by bimaxillary advancement surgery performed in patients suffering from obstructive sleep apnea (OSA). The aim of the present study is to analyse the volume of nasal and maxillary sinus after bimaxillary advancement surgery in patients suffering from OSA. The maxillary sinus and nasal complex of eighteen patients with OSA was measured through cone-beam computed tomography (CBCT) before and after they were treated with bimaxillary advancement surgery.

Correlation between polysomnographic parameters and volumetric changes generated by maxillomandibular advancement surgery in patients with obstructive sleep apnea: a fluid dynamics study.

Study Objectives: Maxillomandibular advancement surgery (MMA) is a therapeutic option for obstructive sleep apnea (OSA). The main objective of this study was to determine the impact of MMA on the physical and airflow characteristics of the upper airway based on data obtained by computational fluid dynamics (CFD) and to correlate these data with polysomnography parameters. Other objectives included the identification of presurgical variables that could help avoid surgeries likely to have a low success rate.

Tridimensional upper airway assessment in male patients with OSA using oral advancement devices modifying their vertical dimension.

Study Objectives: Mandibular advancement devices (MADs) constitute an alternative treatment in selected patients with OSA. A mandibular advanced position has been suggested to be beneficial, whereas its combination with an increased bite-raise may increase its adverse effects. The objective of this study was to assess upper airway (UA) volume and inspiratory pressure gradient variations in a group of 17 patients with OSA.

Clinical, esthetic, and quality of life outcomes after telegnathic surgery in Caucasian OSAS patients.

: To carry out both an objective and subjective assessment of the facial esthetics, clinical outcome, and quality of life evaluation in 25 OSAS patients treated with telegnathic surgery.: Patients were analyzed using AHI, Legan and Burstone and airway cephalometric analysis for the objective study together with youthful and esthetic perception and SF-36 health surveys for the subjective part.: Facial convexity, nasolabial and lower face-throat angle, upper lip protrusion, and vertical height-depth ratio improved the facial and neck esthetics, while the maxillary and mandibular prognathism increased.
