Abstract
Background
The soft palate and the lateral pharyngeal walls contribute to the collapse of the upper airway in patients with snoring and obstructive sleep apnea. In this study, the original soft palatal webbing flap palatopharyngoplasty for both soft palatal and oropharyngeal lateral wall collapse has been modified to include all tonsil grades and to apply the barbed suture technique.
Methods
Twenty-one adults with significant soft palatal webbing, lateral pharyngeal wall collapse, and tonsil hypertrophy of any grade were selected for the study with a minimum follow-up period of 6 months.
Results
Snoring was improved with snoring scale reduced from 9.4 ± 1.6 to 1.7 ± 3.2 (p < 0.005). The preoperative to postoperative apnea-hypopnea index (AHI) statistically improved from 45.7 ± 2.6 to 12.3 ± 3.9 (p < 0.005) and lowest O2 saturation from 73.8 ± 3.6 to 89.4 ± 1.9 % (p < 0.005). Postoperative endoscopic findings showed significant improvement in soft palatal and lateral pharyngeal wall collapse. There were no significant intraoperative or postoperative complications.
Conclusion
Modified barbed soft palatal webbing flap palatopharyngoplasty provided objective improvement of obstructive sleep apnea (OSA) in adults with soft palatal, lateral pharyngeal wall collapse and tonsillar hypertrophy, with no significant complications and has the potential to serve as an effective alternative for these cases.
