Plain-English summary
A 3-year-old male Labrador retriever was brought in because he could only hear loud and high-pitched sounds. The vet found that the dog had a condition called atresia, where the ear canals were not fully formed, which was confirmed through imaging tests. After surgery to correct the ear canals, follow-up hearing tests showed that the dog's ability to hear improved significantly. This case highlights how surgery can help dogs with certain types of hearing loss regain their hearing.

Abstract
A 3 yr old male castrated Labrador retriever presented for evaluation and treatment of bilateral atresia of the external ear canals. The owners reported that the dog could hear only loud and high-pitched noises. Computed tomography of the head revealed intact vertical and horizontal ear canals filled with debris and a debris-filled right tympanic bulla. Air- and bone-conducted brainstem auditory evoked response (BAER) testing revealed an elevated response threshold to air-conducted stimuli and greater amplitude waveforms evoked by bone-conducted stimuli. The ear canals were surgically corrected via lateral ear canal resection. BAER testing postoperatively revealed a decrease in the air-conducted BAER threshold. This case is an example of the use of bone-conducted BAER testing to aid in the diagnosis of conductive deafness, and in determining prognosis for normal hearing after surgical treatment of external ear canal atresia.
