Evaluation of a modified hemimandibulectomy for treatment of oral neoplasms in dogs.
A modified hemimandibulectomy was performed for treatment of oral neoplasms in 21 dogs. Intra- and postoperative evaluations included assessment of procedure difficulty, complications, mastication, cosmesis, and the time interval between surgery and recurrence of the neoplasm or clinical evidence of metastasis. Malignant melanoma was the most common neoplasm treated using this technique. The modified hemimandibulectomy was uncomplicated with minimal intraoperative hemorrhage. Three dogs had difficult mastication at 24-hours following surgery, while 5 dogs had partial wound dehiscence. Wound infection was diagnosed in 1 dog. All owners considered the postoperative outcome to provide acceptable cosmesis. Local neoplasm recurrence was documented in 5 dogs and distant (pulmonary) metastasis was diagnosed in 5 different dogs following surgery. The technical modification described in this study seemed to provide for improved mastication during the acute postoperative period compared with other hemimandibulectomy techniques performed by the authors.
