目的：磨牙后区的解剖和组织学结构比较特殊，该部位的恶性肿瘤在临床、病理、手术及修复方法等方面与其它部位不同。现就此进行回顾性研究。材料和方法：本文回顾性分析了我院１９８０年６月至１９９７年１２月间收治的４３例磨牙后区恶性肿瘤患者，其中５例采用单纯化疗，１９例采用单一手术治疗，１７例采用化疗后手术的综合治疗，２１例在病灶切除后即刻手术修复。结果：该组病例５年生存率为３７％，但仅使用化疗的５例病人生存期均低于２年。结论：手术切除方法是磨牙后区恶性肿瘤的主要治疗方法。
OBJECTIVE: The anatomical and histological structures of the retromolar area are rather special. Malignant tumors at this site differ from other sites in terms of clinical, pathological, surgical, and repair methods. This is a retrospective study. Materials and Methods: This article retrospectively analyzed 43 patients with malignant tumors in the molar area treated in our hospital from June 1980 to December 1997. Among them, 5 cases were treated with chemotherapy alone, 19 cases were treated with single surgery, and 17 cases were treated with chemotherapy. After comprehensive treatment of postoperative surgery, 21 cases were repaired immediately after resection of the lesion. RESULTS: The 5-year survival rate was 37% in this group of patients, but the survival time was lower than 2 years in only 5 patients treated with chemotherapy. Conclusion: Surgical resection is the main treatment for malignant tumors in the molar area.
