Based On The Theory Of "phase Surgery" Of Traditional Chinese Medicine, The Facial Features Of Patients With Obstructive Sleep Apnea Hypopnea Syndrome Were Studied

Objective:In recent years,there has been an increase in the prevalence of obstructive sleep apnea hypopnea syndrome(OSAHS).It not only results in sleep disorder,but also associated with the occurrence and mortality rate of hypertension,metabolic syndrome,cardiovascular and cerebrovascular diseases,cognitive dysfunction,and the like,which posed great risk for the human health.So the early diagnosis and treatment of OSAHS is becoming the essential component for health wellness.Polysomnography(PSG)is the most important diagnostic tool for sleep apnea,but it has the limitations of complicated procedure,high cost,time consuming and difficult in adjusting for the first time.Previous studies have shown that certain features of the face,such as the lower jaw,the larger ANB Angle,the large Angle of the jaw,and Class ii malocclusion,can indicate the high risk of OSAHS.Therefore,this study is to explore the facial morphological features of OSAHS patients by using the method of photo measurement to collect the features of human facial features of OSAHS patients,so as to provide a feasible and cost effective method for early screening,and provide preliminary data for future studies.Method:The subjects were collected from 160 patients.After obtaining the informed consent of the subjects,we collected their general information and facial information,and at the some time we confirmed the diagnosis of sleep apnea,using Portable Monitoring Devices(ResMed ApnealinkTMPlus)to monitor their sleep overnight.According to AHI,they were divided into four groups:non-OSAHS,mild,moderate,and severe(<5,5?<15,15?<30,or more than 30 times/h).Using Photoshop CS4 to measure facial information data,28 subjects were excluded from the measurement due to occlusion.The analysis of the remaining 132 subjects(N male =98,N female =34)facial image data includes the distance between the midpoint of the hairline and Yin tang,Yin tang and Zhun tou,Shan gen and Zhun tou,Zhun tou and Di ge,Cheng jiang and Di ge,Yin tang and Di ge,the length of philtrum,the width between the mandibular angle point,and the distance between the outer corner of the eye,the distance between the inner corner of the eye,and the width of face,the lower ear,mouth,and nasal base breadth,and the height of Shan gen,and Angle 1,which is between the lower ear point-mandibular angle point and mandibular angle point-the chin point in front projection,and Angle 2,which is between the lower ear point-mandibular angle point and mandibular angle point-the chin point in the right side of 45°.The following data are calculated:Yin tang-Di ge/the midpoint of the hairline-Yin tang,Yin tang-Zhun tou/Zhun tou-Di ge,Yin tang-Di ge/the width between the mandibular angle point,the morphological facial index,the physiognomic facial index,and the zygomatic frontal index.We record the measurement and calculation results into Excel sheet,and use IBM SPSS Statistics 20.0 for statistical analysis to explore the concordance between the two measurements.Logistic regression analysis was performed for each index.Results:1.Compared with non-OSAHS,group OSAHS showed statistical difference in neck circumference(NC),the width between the point of lower ear,the width between mandibular angle point,Yin tang-Di ge/the width between mandibular angle point,the physiognomic facial index,and the zygomatic frontal index.(P<0.05)2.Compared with non-OSAHS,mild and moderate group showed statistical difference in Yin tang-Di ge/the width between mandibular angle point,and the zygomatic frontal index,(P<0.05)while moderate and severe group showed statistical difference in NC and the physiognomic facial index.(P<0.05)3.In Men,OSAHS group showed statistical difference in the width between the point of lower ear,the width between mandibular angle point,Yin tang-Di ge/the width between mandibular angle point,and the zygomatic frontal index.However,in Women,there is statistically different in NC of OSAHS group(P<0.05).4.In Men,compared with non-OSAHS,moderate group showed statistical difference in Yin tang-Di ge/the width between mandibular angle point and NC,while severe group showed statistical difference in neck circumference(NC),the width between the point of lower ear,the width between mandibular angle point,Yin tang-Di ge/the width between mandibular angle point,the physiognomic facial index,and the zygomatic frontal index(P<0.05).In Women,compared with non-OSAHS,moderate group showed statistical difference in nasal base breadth and NC,while severe group showed statistical difference in Angle 2(P<0.05)5.Compared with non-OSAHS,OSAHS(AI>HI)group showed statistical difference in Yin tang-Di ge/the width between mandibular angle point,the physiognomic facial index,NC and the height of Shan gen(P<0.05).6.In the multi-factor comparison,the facial expression index and BMI were statistically significant(P<0.05),which was an independent risk factor for moderate and severe OSAHS.Conclusion:The OSAHS patients generally exhibit a short,wide,rounded shape feature of the lower part of the face.Male OSAHS patients exhibit facial width,short,and "round"appearance characteristic,and the maxillary width is close to that of face width;Women OSAHS patients focus on features that show a rough neck.Besides,low Shan gen,rough neck and round face are the characteristics of the face of the OSAHS(AI>HI).However,women showed no difference in Shan gen height difference,but showed larger Angle 2.The facial type of non-OSAHS male group is the leptoprosopy,while OSAHS male group's belongs to the mesoprosopy.The facial type of all female subjects in this study is presented with leptoprosopy.The larger BMI,the shorter the face,the higher the risk of severe OSAHS.
