Background. The exact etiology of congenital atresia of the external auditory canal (CA of the EAC) is unknown. Associations were postulated between CA of the EAC and toxins, infections, the incidence was 1 in 8,000 births. Unilateral CA of the EAC is 3-4 times more likely to occur than bilateral atresia. Objective of the study. Presentation of a clinical case, with rarely encountered in medical practice pathology, congenital atresia of the external auditory canal. Material and Methods. Patient, female, 20 years old. Admitted on 06.09.2015 in the ENT department of the Republican Clinical Hospital presented with: Hearing loss in AD (VS-0m .;VC - 1 m.). The tonal audiogram shows transmission deafness on the affected side of 40-70 dB on different frequencies. Objective: microtia on the right, lack of right EAC. CT of the temporal bones confirms the diagnosis. Results. The treatment was exclusively surgical. In the first stage, the atticotomy was performed with the subsequent anthrotomy, highlighting the ossicular chain-intact and mobile. Second stage – miringoplasty using temporal aponeurosis. The intervention finished with meatoplasty using skin grafts from the retroauricular region.Sutures removed at 7 days postoperatively. EAC tampons removed at 4 weeks after surgery. The tonal audiogram, performed over 8 weeks postoperatively, shows hearing within normal limits. Conclusion. CA of the EAC is a rare congenital condition. Imaging and audiological examination is mandatory. The treatment of choice is surgery with the chance of hearing improvement. CA of EAC may be accompanied by other topographic abnormalities of the facial nerve, dura mater. |
