Ventral Bulla Osteotomy for Treatment of Otitis Media in a Rabbit

This article describes the management of otitis media in a domestic rabbit (Oryctolagus cuniculus) that presented with a history of chronic upper respiratory disease. Deep nasal culture yielded a pure growth of Bordetella bronchiseptica susceptible to chloramphenicol. To further evaluate recurring clinical signs after treatment with chloramphenicol, skull radiographs were obtained and showed an increased density in the right tympanic bulla. A ventral bulla osteotomy was performed, and the success of treatment was determined by the resolution of respiratory signs and the absence of increased radiographic density in the right tympanic bulla 5 months postoperatively.
