Abstract
Objectives The aim of this study is to explore the efficiency of lateral pharyngoplasty as a new treatment for obstructive sleep apnea hypopnea syndrome (OSAHS) versus uvulopalatopharyngoplasty (UPPP). Study design Prospective randomized study. Patients and methods This study was submitted on 30 patients diagnosed to have OSAHS with retropalatal obstruction classified randomly into two groups: in one group, we performed the lateral pharyngoplasty (15 cases) with blunt palatal tunneling, and in the other, we did the UPPP (15 cases). We compared the efficiency of surgeries subjectively through the Epworth Sleepiness Scale and objectively through clinical and polysomnographic findings. Results In the lateral pharyngoplasty, the mean apnea-hypopnea index (AHI) improved from 40.95 ± 28.50 to 8.92 ± 7.9 ( P P 2 from 91.93 ± 4.67 to 94.27 ± 3.53% ( P 2 from 71.8 ± 10.56 to 81.27 ± 8.92 ( P P < 0.05). Conclusion The lateral pharyngoplasty may offer benefits over UPPP in treatment of OSAHS patients with retropalatal obstruction. We observed improvements after the two surgeries, but the lateral pharyngoplasty gave better polysomnographic findings with less complications.
