Effectiveness of prosthetic mandibular advancement for obstructive sleep apnea: analysis by sleep position.
Fifteen patients with obstructive sleep apnea were treated using prosthetic mandibular advancement (PMA). Each patient was evaluated in the supine and lateral decubitus positions with and without PMA. After PMA treatment, the mean intraesophageal pressure (Peso) in the supine position improved from -42.6 to -27.3 cmH2O and the mean apnea + hypopnea index (AHI) decreased from 48.8/h to 23.7/h. The mean Peso in the lateral decubitus position improved from -27.9 to -18.6 cmH2O and the mean AHI decreased from 9.6/h to 6.6/h. With PMA, respiratory, disturbance during sleep further improved by changing the body position from the supine to lateral decubitus position.
