Introduction: Congenital aural atresia (CAA) is an abnormality of the external ear along with hypoplasia or aplasia of the external auditory canal. Surgery of aural atresia is not only challenging but also has not been accepted by the surgeons. Many surgeons hesitate to undertake the repair due to inadequate hearing outcome and probability of stenosis of the new canal. This report presents the authors' experience of surgical treatment of aural atresia. Materials and Methods: A retrospective analysis of 31 cases of CAA operated during 2002–2018 in a tertiary referral center was performed. Unilateral atresia was more common. A combined anterior and posterior approach was employed in all the cases. Postoperatively, the patients were evaluated for hearing improvement and any sequelae of surgery at varying period up to 3 months. Results: Twenty-eight patients underwent surgery after exclusion of three patients due to diploic mastoids. A postoperative air-bone closure of >25 dB was achieved in 15 out of 28 patients. Five patients had air-bone closure of 15–25 dB. Only 8 patients did not have any hearing improvement. Meatal stenosis occurred in 2 patients. There were no other complications. Conclusions: Patients with CAA of moderate grade favorable radiological findings may benefit with surgery for better hearing outcomes. Bone-anchored hearing devices can be advised if the surgery is not feasible, particularly in high-grade atresia and unfavorable radiology.
