Abstract
Maxillectomy was used in the treatment of 23 dogs and four cats with oral tumours and one dog with osteomyelitis. The major post‐operative complication was wound dehiscence. All dehiscences occurred in dogs with tumour epicentres caudal to PM1. Maxillectomy in eight dogs with oral fibrosarcoma gave disappointing results (median survival time of 7 months and a median tumour‐free interval of 3½ months). Three of four dogs with squamous cell carcinoma were tumour free after a minimum follow‐up period of 6 months; two of these dogs received orthovoltage radiation therapy following surgery. Maxillectomy provided excellent local control of benign tumours: three epulides and one atypical odontogenic tumour did not recur (minimum follow‐up period was 10 months); an osteoma recurred after 17 months. Four cats, three with squamous cell carcinoma and one with fibrosarcoma, developed local tumour recurrence within 4 months.
