Abstract
OBJECTIVE: Most reports in the literature focus on the efficacy of a single procedure for obstructive sleep apnea (OSA). We review the overall efficacy of a surgical methodology based on localizing the level of anatomic obstruction for each patient and surgical correction of the nasal, oropharyngeal, or hypopharyngeal obstruction.
STUDY DESIGN AND SETTING: Retrospective review of cases performed by a single practitioner using a systematic approach to surgery for OSA with pre-operative and postoperative sleep studies.
RESULTS: Forty-two patients with a respiratory disturbance index (RDI) greater than 15 were included in the study. Surgery involved at least 2 levels of obstruction usually performed in 2 stages. All patients reported symptomatic improvement. Overall, 83.3% (35 of 42) of patients were cured according to the accepted RDI criteria of more than 50% reduction and final RDI of less than 20. All 21 patients with mild OSA (RDI, <29), 73% of patients with moderate OSA (RDI, 30 to 49), and 50% of patients with severe OSA (RDI, >50) were cured.
CONCLUSION: The use of an anatomically based methodology in approaching patients with OSA seems to offer a higher efficacy than a single procedure as reported in the literature. (Otolaryngol Head Neck Surg 2003;129:327–35.)
