Obstructive sleep apnea: a comparison of continuous positive airway pressure and surgical treatment

Since earlier descriptions of the syndrome of obstructive sleep apnea (OSA), various treatment alternatives have included a variety of medical regimens, continuous positive airway pressure (CPAP), tracheostomy, and other surgical options. A lack of acceptable criteria for surgical intervention remains an important concern for the surgeon. in an attempt to resolve some of the controversies pertaining to various therapeutic modalities, we performed a retrospective analysis--from 1983 to the present--of posttreatment results in patients who underwent surgical therapy and those who were treated primarily with CPAP at this institution. Of 400 patients diagnosed with OSA, only 66 underwent surgical treatment, including uvulopalatopharyngoplasty. CPAP was the mainstay of treatment in the majority of our patients. Post-treatment data were available for 50 patients treated with CPAP and for 45 patients treated surgically. A comparative analysis of polysomnographic studies revealed superior cures with CPAP, although long-term compliance remains a significant problem. We advocate CPAP as initial therapy in patients with no clinically apparent causes for obstruction (e.g., nasal polyps, deviated nasal septum, or obstructive tonsillar hypertrophy) because of the predictability of success, and lower costs and complication rates. Long-term followup of OSA patients is indicated, regardless of treatment modality.
