Abstract:Objective  To enplore the methods to  effectively control the postoperational complications and improve the curative effect in treatment  of  obstructive sleep apneahypopnea syndrome(OSAHS).Methods 59 patients with typeⅠ OSAHS were divided into two groups.The patients in experiment group(39 cases) were treated with  soft palate landscape orientation two fusiform cuts and enlarged two amygdales resection;the patients in  control group(20 cases) were treated  with  uvulopalatopharyngoplasty (UPPP) or reserving uvula UPPP.The PSG at preoperation and postoperation,and snore rate,Epworth score at  postoperation in  two groups were analyzed and compared.The intension and the time of duration of postoperation pharyngalgia,backflow from nasal cavity or missing deglutition,cavum pharyngis stenosis were observed.Results The effective rate in experiment group was 92.31%,in control group was 70.00%,there was significant difference between two groups （P<0.05);compared with preoperation,the  AHI was decreased（P<0.05) and the average arterial oxyhemoglobin saturation was increased（P<0.05)after operation.There was no significant difference in PSG  between two groups;compared with control group,the degree of pharyngeal ache in experiment group was redeced after operation;after 6-12 months follow-up,there were  significant differences in the changes of snore,nasopharynx’s backflow or missing deglutition and cavum pharyngis stenosis (P<0.05).Conclusion Soft palate landscape orientation two fusiform cuts and enlarged two amygdales resection  not only  completely reserve uvula,but also  enlarge soft palate shaping confines in treatment of OSAHS;not only effectively enlarge the ventilate’[KG-*5]s sectional area of cavum oropharyngeum,but also preferably keep the normal physiological morphology and function of cavum pharynges and avoid the occurrence of complications such as palatepharynx insufficiency,etc.
