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.
