TL;DR: Partial maxillectomies were performed in 17 dogs and three cats to accomplish wide excision of oral tumors to effective in treating both benign and malignant oral tumors in dogs and cats.
Abstract: Partial maxillectomies were performed in 17 dogs and three cats to accomplish wide excision of oral tumors. The extent of the maxillectomy was dependent on tumor type, location, size, and invasiveness as determined by clinical and radiographic examination and incisional biopsy. The tumor and involved portions of adjacent facial bones, most commonly the maxillary and incisive bones, were removed. The resulting oronasal defect was closed by suturing a labial mucosal flap based on the lip margin to the hard palate mucoperiosteum. The major postoperative complication was partial suture line dehiscence, which occurred in three dogs. All four dogs with benign tumors were free of disease 7 to 34 months postoperatively (median 21.5 months). Of the 13 dogs treated for malignant neoplasia, seven were tumor-free at follow-up times ranging from 3 to 31 months (median 12 months). Five dogs with malignant tumors developed local recurrence 1 week to 10 months postoperatively (median 4.5 months). One cat with a benign tumor and two with malignant tumors were tumor-free at follow-up times of 7, 24, and 27 months. Partial maxillectomy can be effective in treating both benign and malignant oral tumors in dogs and cats.
TL;DR: Reconstruction of posterior maxillectomy defect is proven feasible by transport distraction osteogenesis and new bone bridging the distraction gap was confirmed by radiography and histology in the animals completing distraction.
TL;DR: The quality of the pets' lives was perceived by the owners to be most improved after rostral mandibulectomy and least improved after partial maxillectomy, and all owners found the cosmetic appearances of their dogs acceptable after facial hair regrew.
Abstract: Twenty-seven dogs with oral tumors were treated with either rostral mandibulectomy, partial mandibulectomy, or partial maxillectomy. Owner satisfaction with the respective surgical procedure was assessed by telephone survey; 85% of owners were satisfied with the decision to treat their dogs. The percentage of satisfied owners was directly proportional to the increase in pet life span. Although difficulty in eating was noted for 12 (44%) of 27 dogs, pain was perceived to be reduced by the surgery for most animals. All owners found the cosmetic appearances of their dogs acceptable after facial hair regrew. The quality of the pets' lives was perceived by the owners to be most improved after rostral mandibulectomy and least improved after partial maxillectomy.
TL;DR: From 1950 through 1975, 54 patients with mucoepidermoid carcinoma of the oral cavity were treated at the Mayo Clinic; nine patients died of their disease.
Abstract: From 1950 through 1975, 54 patients with mucoepidermoid carcinoma of the oral cavity were treated at the Mayo Clinic. Metastatic disease occurred in 13 patients; nine patients died of their disease. Mucoepidermoid tumors of the hard palate should be treated by partial maxillectomy. Complete neck dissection is necessary for tumors larger than 2 cm in the base of the tongue. Other intraoral mucoepidermoid carcinomas are treated by wide surgical excision.
TL;DR: A case of desmoplastic variant of ameloblastoma, in a 36-year-old Japanese woman, was successfully treated by partial maxillectomy and reconstruction was carried out with a block of hydroxyapatite about 7 years and 6 months later.
