Otitis media is a highly prevalent disease process in pet rabbits. This condition is difficult to diagnose and treat as usually clinical signs do not arise until the disease is advanced. Computed tomography (CT) has been reported as a reliable method of diagnosis and has been used for disease grading. Currently, conservative and surgical managements are described in the literature. The conservative method of treatment involving antibiotics has been found to not always be effective as there is inadequate penetration of the middle ear. The surgical option of choice, bulla osteotomy with or without marsupialization may have complications. Although two recent studies have described outcomes of bulla osteotomy, neither of them had clear description of CT follow-up. The objective of this retrospective cohort study is to assess long term outcomes of surgical bulla osteotomy vs conservative treatment as assessed by CT. Data from rabbits seen at the Cornell University Hospital for Animals (CUHA) for otitis media and treated either surgically or conservatively along with having at least two CTs pre and post treatment over a span of at least 6 months were extracted from 2017- present. The grade of otitis media was described pre and post treatment using the CT scans to evaluate long term effectiveness of treatment options.
