Objective

To report surgical treatment of severe otitis media in an alpaca by a modification of a subtotal ear canal ablation and lateral bulla osteotomy technique used in dogs.

Study Design

Case report.

Animals

An 11-week-old female alpaca cria.

Methods

The cria had a 2-week history of right otitis media, nonresponsive to medical treatment, as well as right facial nerve paralysis, and a melting corneal ulcer of the right eye. Otitis media was confirmed by computed tomography. Right subtotal ear canal ablation and lateral bulla osteotomy were performed using a modification of a technique reported in dogs.

Results

There were no surgical complications and the alpaca was discharged from the hospital 5 days later. At 10 months, moderate motor function had been restored to the pinna with the ear standing partially erect. The otitis had resolved, and the alpaca was reportedly well integrated into the herd.

Conclusion

Subtotal ear canal ablation and lateral bulla osteotomy, a technique modified from that performed in dogs, were successful in providing complete clinical resolution of otitis media in an alpaca.
