Microtia and anotia in a dog

Abstract

The aim of this case presentation is to report microtia and anotia in a 3‑year‑old female dog. Owner complained
about hearing loss and absence of auricles. There were no auricles in both control ears in clinical examination. Degree of the hearing
problem was nearly deafness. A fistula was determined in left lateral cranial side. Grade III microtia and grade IV anotia were diagnosed
in the ear canal of the left and right sides, respectively. Under general anesthesia, the dog underwent auricular reconstructive surgery
for microtia on the left side. Two weeks after operation, the owner evaluated the patient’s hearing as moderate. This finding was
clinically confirmed through performance of the Pyror’s reflex. In conclusion, grade III microtia can be treated surgically to improve
the conductive hearing of the patient.
