Predictive values of the combination of Friedman stage and sleep oximetry done early after surgery in predicting the treatment outcomes of uvulopalatopharyngoplasty

To explore the predictive values of the combination of preoperative data, including medical history and physical examination, and results of sleep oximetry performed early after the surgery (one week) in predicting the treatment outcomes of uvulopalatopharyngoplasty (UPPP) in adult patients with obstructive sleep apnea hypopnea syndrome (OSAHS). All the patients who were diagnosed with OSAHS, underwent UPPP treatment and had complete follow-up data in our institution between Jan 2013 and May 2016 were enrolled in our study. The pre-operative data of these patients, including age, physical examination, and polysomnography (PSG) data, were all exactly collected for analysis. All these patients had received the evaluation of subjective efficacy scale and the sleep oximetry test in early post-operative days (within one week). The long-term efficacy evaluations including PSG and subjective efficacy scale were all finished at least three months after the surgery. In the research 61 patients were finally studied, in
