Study On The Correlation Between Soft Palate Morphology And OSAHS

Objective:Due to the numerous related factors causing OSAHS,the treatment methods are also different.In order to more accurate understanding of the soft palate on the impact of the disease,we through X-ray thrum shadow measurement to obtain the static form of the soft palate and cranial Mian Ruan organization some anatomical data,combined with the patients of PSG results analysis,discusses the static form of the soft palate and related indicators and OSAHS correlation,so as to provide reference for subsequent accurate treatment.Methods:Sixty-nine outpatient and inpatient adult patients diagnosed with OSAHS by PSG in the Department of Otolaryngology,Head and Neck Surgery of Yijishan Hospital,Wannan Medical College were randomly selected as the case group of this study,and thirty-five healthy adults without snoring were selected as the control group.Measured and recorded two groups of general information:height,weight,age,gender,abdominal girth,waistline,neck circumference,body mass index,tongue indexing,X thrum shadow position on airway and craniofacial soft tissue anatomic parameters（including the thickness of the soft palate,the length of the soft palate,soft hard palate Angle,palatal clearance,tongue after minimum clearance）,the soft palate morphology of surveying and mapping,etc.Finally,SPSS22.0 statistical software was used for correlation analysis of all the data,and the relevant data were further processed,focusing on the correlation between different soft palate static morphology,tongue position grading and craniofacial anatomical parameters and OSAHS.Results:A total of sixty-nine patients in the OSAHS case group and thirty-five healthy control group were included in this study.The distribution of soft palate morphology in the two groups were willow leaf shape,rat tail shape,fine line shape and S type,and there was no short and thick type and internal hook type,and the difference in the distribution of soft palate morphology was statistically significant（χ2=6.005,P=0.001）.The proportion of S type in the case group was significantly higher than that in the control group.Although the degree of OSA disease in S type patients was relatively more severe than other soft palate forms,the difference was not statistically significant（H=7.634,P=0.054）.The thickness and length of the soft palate,the posterior palatal space and the Angle of the soft and hard palate were statistically significant between the two groups（P<0.05）.In the disease group and the thickness of the soft palate AHI,no correlation between LSa O₂index,the soft palate length was positively correlated with AHI index（p<0.05）,negatively correlated with LSa O₂（p=0.012）,the soft palate,Angle was positively correlated with AHI index（p<0.05）,and there is no correlation between LSa O₂（p>0.05）,and after palatal clearance with AHI index showed a negative correlation between（p=0.002）,and LSa O₂were positively correlated（p<0.001）.The difference of tongue position was statistically significant between the two groups（Z=8.041,P<0.001）,and it was also correlated with the degree of OSA disease（H=11.932,P=0.008）.Further pair comparison showed that the degree of disease in patients with tongue position grade II and III was more serious than that in patients with tongue position grade I,with statistical significance（P<0.05）.Conclusion:Static morphology classification of soft palate is closely related to the incidence of OSAHS,and the proportion of S type in the incidence of OSAHS is significantly higher than that in the control group;The length of the soft palate,the Angle of the soft and hard palate and the posterior palatal space measured by X-ray cephalometry are closely related to the incidence and severity of OSAHS;The morphology of adult soft palate was mainly willow leaf shape,rat tail shape,fine line shape and S shape,and there was no short and thick shape and inner hook type.
