Combined resection of the nasal planum and premaxilla in three dogs.

Surgical techniques for removal of tumors that affect the nasal planum or the premaxilla have been described. For extensively invasive malignancies, these techniques may be inadequate if used alone to achieve wide surgical margins. An operative technique that combines resection of the nasal planum and premaxilla has been developed for extensive malignant tumors of the nasal planum or premaxilla. This technique was used in three dogs and resulted in an acceptable cosmetic appearance and good function and tumor control. Complications after surgery included minor bleeding and partial dehiscence of the suture lines in two dogs and stenosis of the nasal orifice in one dog.
