Total laryngectomy and permanent tracheostomy in six dogs.

The objective of this report is to describe the surgical technique for total laryngectomy and outcome in six dogs. Laryngeal cancer is an uncommon and challenging clinical problem. Total laryngectomy can provide local disease control but is uncommonly performed. Detailed procedural descriptions are limited and similarly limited information is available regarding patient outcome. Institutional medical records were searched for dogs treated with total laryngectomy. Six dogs were identified. The procedure resulted in postoperative quality of life similar to permanent tracheostomy alone. Surgical margin status was evaluated in five of six cases and was complete in those five. All dogs survived to discharge from the hospital. Complications were mostly related to tracheostomy occlusion or collapse which is recognized as a complication associated with permanent tracheostomy. Patient quality of life was acceptable. Local recurrence was suspected in one dog. Recurrence was not observed in the case with unknown margin status.
