随着上颌癌瘤治疗手术的发展,手术范围的扩大,上颌骨全切除或扩大切除术并非少见。据我院1983—1989年不完全统计,在105例上颌骨切除病例中,扩大切除25例,全切除37例共占59％。而上颌骨的结构复杂,又有着重要的解剖结构与它毗邻,易出现各种并发症。为减少常见并发症的发生,本文结合解剖特点,提出有效的防治措施。 With the development of maxillary cancer treatment surgery, the expansion of the scope of surgery, maxillofacial resection or expanded resection is not uncommon. According to our hospital 1983-1989 incomplete statistics, in 105 cases of maxillary resection, the expansion of 25 cases, total removal of 37 cases accounted for 59%. The structure of the maxillary complex, but also has an important anatomical structure adjacent to it, prone to complications. In order to reduce the incidence of common complications, this article combined with anatomical features, put forward effective prevention and treatment measures.
