Original publication title: Para-aural abscessation following traumatic ear canal separation in a dog.
Plain-English summary
A 5-year-old mixed-breed dog was brought in for a swollen ear after experiencing a traumatic separation of the ear canal. The vet found that the dog had developed a para-aural abscess, which is an infection near the ear. To treat this, the vet performed a total ear canal ablation and lateral bulla osteotomy (TECA/LBO), a surgery that removes the ear canal and part of the ear structure. After the procedure, the dog recovered well and no longer showed signs of infection or discomfort.

Abstract
Traumatic ear canal separation is rare in animals, with only eight dogs and one cat reported with the condition in the English language literature. Para-aural abscessation occurred in six of these nine animals. Diagnosis was made on otoscopic observation of a shortened, abruptly ending external ear canal that was free from advanced disease. Radiographs in those cases which have been described showed a disruption of the normal air opacity of the affected ear canal. Drainage, by creating a separate opening for the horizontal ear canal, or total ear canal ablation and lateral bulla osteotomy (TECA/LBO), have led to resolution of the clinical signs. This report adds a further case to the literature in which TECA/LBO was employed successfully.
