摘　　要：目的 :探讨颌下三角区原发性恶性肿瘤的诊断和治疗的特殊性 .方法 :回顾性分析我院 1984年 1月至 1993年 12月收治的 37例颌下三角区原发性恶性肿瘤患者的临床资料 ,其中腺样囊性癌 11例 ,低度恶性粘液表皮样癌 9例 ,中度恶性粘液表皮样癌 4例 ,恶性混合瘤 3例 ,鳞癌 4例 ,腺癌 2例 ,未分化癌 3例 ,颌下腺导管癌 1例 .所有患者均作手术切除 ,并根据其不同的组织病理特征选择其中 2 4例术后辅助放射治疗 .结果 :本组病例随访3年～ 5年 ,术后 3年生存率为 89.1% 33/ 37 ,5年为 81% 30 / 37 .结论 :颌下三角区原发性恶性肿瘤具有一定的临床特征 ,如 : 1 肿瘤生长较快 ; 2 可伴有局部疼痛 ; 3 可有同侧舌麻、舌痛现象 .治疗以手术切除为主 .根据肿瘤的不同组织病理学特征 ,术后辅助放射治疗 ,可提高疗效 .objective:To explore the specificity of diagnosis and treatment of primary malignant tumor in submandibular region.Method:37 patients with primary malignant tumor in submandibular region from January 1984 to December 1993 were retrospectively reviewed.In 37 cases,11 were adenoid cystic carcinomas,9 were low-grade muco-epitheliomas,4 were middle-grade muco-epitheliomas,3 were malignant mixed tumors,4 were squamous-cell carcinomas,2 were adenocarcinomas,3 were undifferentiated carcinomas and 1 was submandibular gland duct carcinoma.All of the patients were treated by surgery but 24 cases were chosen for irradiation postoperatively according to their histopathologic features.Results:All patients were followed up for 3 years to 5 years postoperatively.The 3-year survival rate was 89.1%(33/37) and 5-year survival rate 81%(30/37).Conclusions:Definite characteristics for the primary malignant tumor in submandibular region were:(1)usually growed rather rapidly;(2)with pain in local site;(3)with tongue paraesthesia in tumor side.Operation was the principal treatment.Accoding to the different histopathologic features of the tumor,use irradiation postoperatively could improve the final results.
