Abstract

Disorders of the ears are some of the most common presentations in first-opinion canine practice; rarely will a day go by when a practitioner doesn’t need to deal with a case of ear disease. This chapter focuses on clinical examination of the ear, aural haematoma, laceration of the pinna, foreign bodies, otitis externa and vestibular disease. : Ear cytology; Otoscopy; Surgical treatment of aural haematoma.

Image of (a,b) Preoperative views, showing the extent of the haematoma. (c) Sutures on the convex surface of the pinna. (d) The concave surface, showing the sutures and drainage channel. The postoperative photographs were taken after removal of the drapes, but before final clean (the sutures continue to ooze for some time afterwards).
