Abstract: Objective To observe the curative effects of combined surgical treatment on obstructive sleep apnea hypopnea syndrome (OSAHS). Methods Nasopharyngeal OSAHS patients were randomly divided the patients from December 2014 to December 2016 were as control group received uvulopalatopharyngoplasty (H-UPPP) .Combined treatment group, including implementation of H-UPPP combined with expansion nasal surgery. We compared two groups of treatment efficiency and operation data, comparing the preoperative and postoperative MSpO2, LSpO2, SpO2, AHI index, PSQI score, the ESS score and complications. Results The effective rate of the combined treatment group was significantly higher than that of the control group. The average time of hospitalization was shorter than that of the control group (P < 0.05). The MSpO2 and LSpO2 in the combo group were significantly higher than those in the control group, while TS90% was lower than that of the control group (P< 0.05). The incidence of AHI index, PSQI score, ESS score and complications after operation in the combined treatment group were lower than that of the control group (P < 0.05). Conclusions H-UPPP combined with nasal dilatation can significantly improve blood gas analysis index and sleep and breathing quality, shorten hospitalization time and reduce postoperative complications, which is worthy of clinical application.
