EMBRYOGENESIS AND ETIOPATOGENESIS ANOMALIES DEVELOPMENT OF THE EXTERNAL AUDIO CANAL
Keywords:
atresia of the auditory canal, anomaly, microtia, etiologyAbstract
It is necessary to understand the etiology of external auditory canal atresia in order to explain the situation to the patient and their family members, plan the operation, predict complications and eliminate them in time, and provide genetic counseling. The etiology of external auditory canal atresia is divided into genetic factors and environmental factors affecting the development of the external ear. Given that the auricle and external auditory canal develop from the same source, microtia and atresia of the external auditory canal often coexist, with atresia of the external auditory canal occurring in up to 74% of patients with microtia.
