Effect Evaluation of Modified Uvulopalatopharyngoplasty With Low-Temperature Plasma and Selective Nasal Cavity Vasodilatation With Tongue Volume Reduction in Patients With Obstructive Sleep Apnea Hypopnea Syndrome

Objective: To compare the clinical effects of modified uvulopalatopharyngoplasty (UPPP) with low-temperature plasma with selective nasal cavity vasodilatation with tongue volume reduction for obstructive sleep apnea/hypopnea syndrome (OSAHS). Methods: A retrospective analysis based on 156 patients with serious OSAHS was used for the evaluation. These patients were divided into 2 groups according to surgery methods according to 1:1.s. The patients in observation group accepted modified UPPP with low-temperature plasma and selective nasal cavity vasodilatation with tongue root volume reduction on the basis of fully preparation for surgery, while the patients in the control group accepted normal treatment. The clinic effects, operative complications, postoperative relapse, and other indexes were compared. Result: After 6 months of follow-up visit, the general effective rates of the observation group and control groups were 80.77% and 61.54%, the difference was statistically significant (P
