盲管伤伤道末端均有异物存留;同时不论盲管伤或贯通伤,碎骨片和碎牙片常形成继发性弹片存在于组织中。因此,颌面损伤时异物存留的比例是很大的。另一方面,颌面及其邻近部位虽小,但重要组织和器官比较集中,取异物时应当考虑的问题较多,技术上也有一定的困难。我们见于国内尚少这方面的报导,願就抗美援朝战争时期和近年来一些粗浅的经验体会,作一简单介绍。一、异物摘除的适应证我们从颌面及其邻近部位发现的异物有弹片、枪弹、碎骨片、碎牙片、石块、木棍和棉花等。发现异物可停留在颌面及其邻近的各个部位,如唇、颊、颏、腮、颧部、舌、
At the same time, whether the blind pipe injury or penetrating injury, bone fragments and broken teeth often form secondary shrapnel exist in the tissue. Therefore, maxillofacial injury, the proportion of foreign body retention is great. On the other hand, the maxillofacial region and its adjacent parts are small, but the important tissues and organs are more concentrated. There are many problems that should be considered when taking foreign materials, and there are some technical difficulties. We see less reporting in this area in our country and would like to give a brief introduction on some superficial experiences during the war on aiding the United States and aid Korea and in recent years. First, the indication of foreign body removal We found the foreign body from the maxillofacial region and its adjacent parts are shrapnel, bullets, bone fragments, broken teeth, stones, wooden sticks and cotton. Found that foreign body can stay in the maxillofacial area and its adjacent parts, such as lips, cheeks, chin, cheeks, zygomatic, tongue,
