Abstract:
OBJECTIVE: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).
METHODS: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.
RESULTS:In the research 61 patients were finally studied, including 25 responders (41.0%) and 36 non-responders (59.0%). Regression analysis revealed that the pre-operative Friedman stage and early post-operative oxygen desaturation index of ≥4% (ODI4) were found to be independently predictive parameters for the UPPP treatment outcomes (P<0.05). The ROC curve analysis was used to estimate the predictive values of ODI4 to the treatment outcomes, and it was calculated with an area under the curve of 0.822. Using the ODI4 of 15 as the cutoff value, the sensitivity and specificity of that calculated were up to 0.778 and 0.760 respectively. The response rate among the patients with an early post-operative ODI4 of <15 was 70.4%, which was significantly higher than that of the patients with an early post-operative ODI4 of ≥15, whose response rate was 17.6% (P<0.05). The similar results could also be obtained in the patients with pre-operative Friedman stage II (87.5% vs.25.0%) and Friedman stage III (33.3% vs. 6.7%).
CONCLUSION:The combination of early post UPPP operation oximetry parameters, especially ODI4, and pre-operative Friedman stage could be used in better evaluating the potential surgical outcomes of UPPP.
