The aim of this work is to stress the importance of and discuss the timing and options for the treatment of congenital aural atresia (CAA), including non-surgical alternative treatment modalities and amplification, and to report the audiological and surgical results of a series of patients. Thirty-eight children with CAA were evaluated with regard to hearing and anatomical anomalies accompanying CAA: the state of the ossicles and the facial nerve, postoperative complications and audiological results. The ages of the patients ranged between 4 and 18 years, with a mean of 10 years. All underwent surgical treatment; 32 had unilateral atresia, while 6 had bilateral atresia. The mean follow-up duration was 7 months. The facial canal was dehiscent in 36.8% of cases. In 70.2% cases, the malleus and incus were present as an ossicular mass, fixed and attached to the atretic bone. The stapes was normal in 97.3% of the patients; in 2.7% the suprastructure was deformed. The success rate, defined as an air-bone gap of 20 dB or less, was 63.1% in this series of patients.

If atresia is bilateral, very early hearing stimulation to prevent the maldevelopment of children’s speech and cognitive skills is of the utmost importance. In unilateral cases, surgery may be postponed until early adulthood, when the patient is able to make his/her own decision and cooperate in the treatment and postoperative aspects. Keywords : congenital aural atresia, air-bone gap, bone mass, hearing aids.
