Hemimaxillectomy was performed in 69 dogs for the treatment of benign or malignant maxillary tumors. Eighteen dogs with ameloblastomas had a median disease-free interval of 21.5 months (range, 1 to 76 months), with a 72% 1-year survival time. There was recurrence in three dogs, with metastasis after malignant transformation in one of them. Based on calculated survival curves, seven dogs with squamous cell carcinoma had a median survival time of 19.2 months (range, 2 to 24 months), with a 57% 1-year survival time. There was local recurrence in two dogs. Twenty-three dogs with melanoma had a median survival time of 9.1 months (range, 1 to 46 months), and a 27% 1-year survival time. Twelve dogs died or were euthanatized because of recurrence or metastases. Fifteen dogs with fibrosarcoma had a median survival time of 12.2 months. Eight dogs died or were euthanatized because of recurrence or metastases. Six dogs with osteosarcoma had a median survival time of 4.6 months (range, 1 to 12.5 months), with a 17% 1-year survival time. Five dogs died or were euthanatized for recurrence or metastases. Tumor size or location and type of partial maxillectomy performed did not affect survival.
对69只犬实施了半侧上颌骨切除术以治疗良性或恶性上颌肿瘤。18只患成釉细胞瘤的犬无病间期的中位数为21.5个月（范围为1至76个月），1年生存率为72%。3只犬出现复发，其中1只在恶变后发生转移。根据计算出的生存曲线，7只患鳞状细胞癌的犬中位生存时间为19.2个月（范围为2至24个月），1年生存率为57%。2只犬出现局部复发。23只患黑色素瘤的犬中位生存时间为9.1个月（范围为1至46个月），1年生存率为27%。12只犬因复发或转移死亡或实施安乐死。15只患纤维肉瘤的犬中位生存时间为12.2个月。8只犬因复发或转移死亡或实施安乐死。6只患骨肉瘤的犬中位生存时间为4.6个月（范围为1至12.5个月），1年生存率为17%。5只犬因复发或转移死亡或实施安乐死。肿瘤大小、位置以及所实施的部分上颌骨切除术的类型均不影响生存。
