Plain-English summary
A dog with a rare ear tumor called a cholesteatoma underwent a new type of surgery that aimed to remove the tumor while preserving the ear's structure and hearing. This method involved a special approach to the ear that allowed the veterinarian to keep the external ear canal intact and even improve the dog's hearing. After the surgery, tests showed that the dog's hearing was still functioning well. This technique not only helps in removing the tumor but also offers a better quality of life by maintaining hearing.

Abstract
A new surgical method for treating cholesteatoma in dogs is described. Although rarely reported in dogs, cholesteatomas may be more common than previously believed. Complete excision of a cholesteatoma is associated with low recurrence and good long-term prognosis. Surgical intervention, with total ear canal ablation and lateral bulla osteotomy, has been recommended in dogs with tumors of the middle ear; however, this technique often results in conductive hearing loss. Through a caudal auricular approach to the tympanic bulla, we were able to preserve the external ear canal, reconstruct the auditory ossicles, and graft the tympanic membrane. Results of brain stem auditory-evoked response tests in the dog revealed intact conduction potentials. A caudal auricular approach to the tympanic bulla is technically possible, preserves normal appearance, and may maintain, or even improve, hearing conduction of affected ears in dogs.
