ABSTRACT
The main types of congenital pathology of the external and middle ear are microtia and atresia/stenosis of the external auditory canal. However, isolated cases of atresia/stenosis of the external auditory canal in combination with normal size and shape of the ear canal are quite rare. The article describes a clinical case of a child during the first year of life with congenital stenosis of the external auditory canal in combination with an anomaly of the development of the auditory ossicles, which was observed for 6 months. The results of extended audiological examination showed an increase in the hearing threshold on the left due to conductive hearing loss. In the case of the patient described in the article, a decision was made to use a wait-and-see approach for the child: dynamic observation by a deafness specialist otolaryngologist no less than once every 6 months.
