Ablação total do conduto auditivo com osteotomia de bula e pinectomia para tratamento de carcinoma de glândula sebácea em cadela

Abstract

The combination of surgical techniques of total ear canal ablation combined with lateral bulla osteotomy (TECA-LBO) are considered the gold standard surgical treatment for dogs and cats with ear neoplasia, cholesteatoma, severe trauma to the ear canal, and chronic external otitis with concomitant otitis media unresponsive to medical treatment. The aim is the complete removal of the ear canal and ear epithelium of the tympanic bulla. This case report describes the clinical presentation, surgical treatment and prognosis of a female Cocker Spaniel, 9 years old, presenting a sebaceous gland carcinoma in the ear canal with a fast and aggressive evolution. The patient was treated with total ablation of the ear canal (TECA) and osteotomy of the right lateral bulla (LBO). The method used as treatment provided excellent results, with no reports or visualization of neurological sequelae and complications from the surgery in the patient to date.
