| Objective:Congenital microtia,also known as small ear disease.The main symptoms include:severe auricle development,external auditory canal atresia,and hearing impairment.Some patients have congenital microtia and external auditory canal.The symptoms of atresia often occur at the same time,and the patient’s middle ear and face are not fully developed.Now,there is no specific reason for the malformation of the small ear.Medical researchers generally say that the living environment and the synergy of genes can lead to the development of microtia.Therefore,this experiment explored the external conditions that caused the microtia.Methods:100 patients with simple small ear malformations admitted to our hospital from January 20 to December 1818 were randomly selected,including 82 male patients and 18 female patients.100 cases of common patients in the pediatric outpatient clinic at the same time were selected as the control group,including 54 male patients and 46 female patients.The comparison and analysis led to the risk factors of small ear malformation in the two groups of sick children.Results:The basic information of the patients can be found in the two groups of patients in the weight of newborn babies,gestational age,education level,maternal age,father’s age,anemia,exposure to radiation,exposure to toxic substances,diabetes during pregnancy and pregnancy There was no statistically significant difference in hypertension data,P<0.05.In the pregnancy history of the affected children,statistical analysis of the mother’s place of residence,polygenerational history,spontaneous abortion history,and abortion history were all risk factors for microtia.The difference of P<0.05 was statistically significant.The habit of smoking or alcohol abuse,as well as the history of the family’s small ear malformation,can cause microtia malformation.Statistical analysis can be found that there is a significant difference(P<0.05).Logistic linear regression model was selected to analyze the data,and the factors influencing the microtia were determined:gender,production frequency,maternal abortion history and father smoking or alcohol abuse habits.The above reasons were compared and found to have significant differences(P<0.05).Conclusion:Through the research,it is found that the pathogenesis of small ear malformation is more,and prevention work can be carried out from many aspects.Genetic factors and living environment are the common pathogenic factors of the disease. |
