一、一般资料上颌窦为恶性肿瘤的好发部位之一,因其位置隐敝,不易早期发现。到确诊时,绝大多数肿瘤已穿破骨壁,侵入四周的软组织,给彻底治疗增加困难。且该部位又与眼、颅脑等重要器官邻近。因此,手术切除边缘多接近肿瘤,并且窦腔引流不畅使手术和放疗都难以发挥各自最好的效果。采用综合治疗,才能提高疗效。本文总结了我科1973-1981年收治40例均经病理证实的上颌窦恶性肿瘤的临床资料,失访按死亡病人计算。本文40例中发病年龄在9～70岁之间,多发年龄在50～59岁之间。见表1。 First, the general information of the maxillary sinus is one of the predilection sites of malignant tumors, because of its hidden position, not easy to find early. At the time of diagnosis, most tumors have pierced the bone wall and invade the surrounding soft tissue, making it difficult to complete treatment. And this part is adjacent to the eye, brain and other important organs. Therefore, surgical resection margins are close to the tumor, and poor sinus drainage may make it difficult for surgery and radiotherapy to exert their best results. The use of comprehensive treatment can improve the efficacy. This article summarizes the clinical data of 40 cases of pathologically confirmed maxillary sinus malignant neoplasm admitted to our department from 1973 to 1981. The age of onset in the 40 cases was between 9 and 70 years old, and the multiple age was between 50 and 59 years old. See Table 1.
