title: Reoperation on patients with obstructive sleep apnea-hypopnea syndrome after failed uvulopalatopharyngoplasty.
abstract: The goals of this study were to explore the reasons after failed uvulopalatopharyngoplasty (UPPP) in some patients with obstructive sleep apnea-hypopnea syndrome (OSAHS), and to observe the efficacy of the second surgery. Twenty-three OSAHS patients with failed UPPP were included in the study. Routine physical exams, electronic endoscopy, computed tomography scan and polysomnography after nasopharyngeal tube insertion were performed to assess the site of upper airway obstruction, and corresponding appropriate surgical treatment was carried out based on the diagnosis. Comprehensive evaluation of the 23 patients revealed that the sites of obstruction after failed UPPP were as follows: 7 cases predominantly in the oropharyngeal area, 2 cases in the nasal, nasopharyngeal and oropharyngeal area, 5 cases predominantly in the glossopharyngeal area and 9 cases in the oropharyngeal and glossopharyngeal areas. Correspondingly, 7 cases underwent improved UPPP alone, 2 cases underwent adenoidectomy or nasal expansion and improved UPPP, 5 cases underwent glossopharyngeal surgery alone and 9 cases underwent improved UPPP and glossopharyngeal surgery. Follow-up for more than 12 months showed that there were four cured cases, 12 cases with marked improvement, and 7 cases with treatment failure. The success rate was 69.6%. After undergoing UPPP, OSAHS patients may still have oropharyngeal airway obstruction. By performing a detailed preoperative assessment on the patient's airway condition and clarifying the site of obstruction, performing the second surgical treatment can still achieve a relatively satisfactory treatment outcome.
