Background Squamous cell carcinoma ( SCC ) is the most commonly reported neoplasm of the nasal planum and treatment is focused on localized disease. Rostral maxillectomy and/or nasal planectomy are considered standard of care for excision of nasal planum SCC ; however, the cosmetic outcome of these procedures can be deemed unacceptable by many pet owners. Objectives The study aim was to evaluate the efficacy of combination carbon dioxide ( CO 2 ) laser surgery and cryosurgery as a palliative treatment modality in dogs with nasal SCC s. Animals Ten client‐owned dogs with nasal SCC were included: seven neutered males, two spayed females and one intact male, with a median age of 12.5 years (range 9–15 years). Methods and materials Tumour CO 2 laser ablation was followed by cryosurgical ablation of the visible tumour, adjacent and subjacent tissue. Three rapid freeze–slow thaw cycles were performed. Results Eight of 10 dogs were Labrador retrievers. The ages ranged from 9 to 14 years. Overall median survival time was 260 days with two dogs still alive at the time of writing. Conclusions and clinical importance Combined CO 2 laser and cryosurgical ablation was practical, cost‐effective and provided an excellent aesthetic outcome in dogs with SCC s restricted to the nasal septum, while providing acceptable palliation of local disease.
