A COST-EFFECTIVE AND RATIONAL SURGICAL APPROACH TO PATIENTS WITH SNORING, UPPER AIRWAY-RESISTANCE SYNDROME, OR OBSTRUCTIVE SLEEP-APNEA SYNDROME

The past decade has seen several innovations in the surgical technique s available for treatment of patients with sleep-disordered breathing. Outpatient techniques such as laser-assisted uvulopalatoplasty (LAUP) and more aggressive procedures designed to address hypopharyngeal and base of tongue obstruction (genioglossus advancement and hyoid myotom y) have been developed and proven successful. We describe the efficacy of LAUP for snoring (72.7%), upper airway resistance syndrome (81.8%) , and mild (mean [+/-SD] respiratory disturbance index [RDI] = 12 +/- 8.1) obstructive sleep apnea (41.7%) in 56 patients who underwent 132 LAUP procedures in a 26-month period. Thirty-two patients with more si gnificant obstructive sleep apnea (mean RDI = 41.8 +/- 23.1) underwent multilevel pharyngeal surgery consisting of genioglossus advancement and hyoid myotomy combined with uvulopalatopharyngoplasty. The surgica l success rate in this group of patients was 85.7% when commonly accep ted criteria were applied, We recommend a stratified surgical approach to patients with sleep-disordered breathing. Progressively worse airw ay obstruction marked by multilevel pharyngeal collapse and more sever e sleep-disordered breathing is treated with incrementally more aggres sive surgery addressing multiple areas of the upper airway.
