Efficacy Analysis of Extended Uvulopalatopharyngoplasty Combined With the Simultaneous Multiplane Operation to Treat Obstructive Sleep Apnea

Abstract

Purpose: The purpose of this study was to discuss the safety and long-term efficacy of extended uvulopalatopharyngoplasty combined with the simultaneous multiplane operation to treat obstructive sleep apnea (OSA). Materials and Methods: Sixty-two patients confirmed with OSA by polysomnography received physical examinations, determination of nasal resistance, Muller’s maneuver under electronic laryngoscope, and upper airway computed tomography scan to locate the obstruction planes. Then the patients received extended uvulopalatopharyngoplasty combined with the simultaneous multiplane operation of the nasal cavity and/or tongue root under general anesthesia. Body mass index, Epworth Sleepiness Scale (ESS) score, apnea-hypopnea index (AHI), and lowest arterial oxygen saturation (LSaO2) were compared before and after surgery. Postoperative complications were recorded. All patients were followed up for 12 to 24 months after surgery. The above-mentioned indicators were determined. Results: Fourteen patients (22.58%) achieved a cure, 20 patients (32.26%) marked effectiveness, 20 patients (32.26%) moderate effectiveness, and 8 patients (12.90%) ineffectiveness. The overall response rate was 87.10%. AHI and ESS score decreased, and LSaO2 increased after surgery than before, all in a significant manner (P<0.05). There was no significant difference in body mass index before and after surgery. No severe complications occurred in any patients. Conclusions: Extended uvulopalatopharyngoplasty combined with the simultaneous multiplane operation had a good safety for OSA, improving ESS, AHI, and LSaO2 significantly. The patients enjoyed an improved life quality after surgery.
