Total Ear Canal Ablation (TECA)

The primary indication is for treatment of otitis externa/media in dogs and cats. At the DVSC, we always perform a lateral bulla osteotomy in conjunction with the TECA. This allows for examination and cleaning of the middle ear compartment, thereby preventing the development of fistulous tract formation postoperatively.

Numerous clients have commented that removal of the diseased vertical and horizontal ear canals greatly improves the patient's quality of life. The need for topical medications is eliminated, and the patient's discomfort is alleviated. Some pet owners have stated that their pets have "acted like a puppy again" following the procedure.

Studies have shown that tumors found within the ear canal are usually best treated with a TECA. This provides the best opportunity for curing the patient of the tumor, and minimizes the risk of leaving neoplastic cells in the surgical field. Localized excision of aggressive tumors, such as ceruminous gland adenocarcinomas, and squamous cell carcinomas often result in tumor regrowth.
