Abstract
BACKGROUND: Obstructive sleep apnea syndrome (OSAS) is caused by a complete or partial obstruction of the upper airway. A new Cahali lateral pharyngoplasty as a stand-alone procedure for the treatment of OSA patients, whatever the level and pattern of airway obstruction in patients with CPAP failure or non-compliant patients, is it? PATIENTS AND METHODS: 40 patients with known OSAS non-compliant with CPAP or CPAP failures included. BMI, Stop-Bang score, and sleep study parameters were reported before and after the new Cahali pharyngoplasty operation. Preoperative DISE was done for all cases. RESULTS: There were 28 (70%) cases with successful operation outcomes, and 12 (30%) failed cases. Postoperative Stop Bang score, AHI, snoring index were significantly reduced in comparison to preoperative data (p-value <0.001); however, minimal SpO2 and baseline SpO2 were significantly increased in comparison to preoperative data. There was a significant improvement in AHI postoperative. Patients collapse at the level of lateral wall hypopharynx, high tongue collapse, laryngeal collapse, tongue palate interaction, all significantly predict failure outcome of the operation (p-value = 0.022). However, the absence of laryngeal collapse (L0) had a successful prediction outcome. The high snoring index significantly predicts operation failure. However, preoperative high baseline SpO2 predicts operation success significantly. CONCLUSION: The new Cahali lateral pharyngoplasty can be used as a stand-alone procedure in the absence of lateral wall collapse at the level of the hypopharynx (LH), high tongue base collapse (TH), laryngeal collapse (L1) or tongue palate interaction.
