左颌面部脊索瘤复发再切除行游离肌皮瓣移植一例
脊索瘤是一种来源于胚胎脊索结构残余组织的肿瘤,呈低度恶性,多数发生在骶尾部和蝶枕联合区,亦发生于颅底、颈椎、胸椎、腰椎等,极少发生于颌面部.我们收治1例复发的左颌面部巨大脊索瘤患者,再切除后游离肌皮瓣修复成功,现报告如下.

颌面部道路交通事故伤的现状与思考
随着人们生活水平的提高和生活模式的转变,创伤的发生率逐年上升,成为影响人类健康和生存质量的突出问题,其中,交通事故伤约占所有创伤的50%以上.据统计,在各类交通事故中,颌面创伤的发生率可高达60%[1],其对口腔功能和颜面的破坏及伴随的社会心理障碍远重于身体其他部位的损伤.目前,交通事故伤的防护与救治已引起世界发达国家的高度重视,我国已将严重创伤损害机制与救治的基础研究列为国家重点基础研究发展规划("973计划")和国家自然科学基金重点资助项目.

颌面部创伤病人的病情观察与护理
口腔颌面部损伤会不同程度地导致解剖结构的破坏和生理功能的障碍,对面容的影响必然加重病人精神上和心理上的创伤,严重并发症会威胁病人的生命[1].护士在护理颌面外科损伤的病人中,必须认真观察病情,及时采取恰当的护理措施,对抢救病人生命和提高治愈率至关重要.本文总结了64例颌面部创伤病人的病情观察与护理体会.

改良手术治疗颌面部恶性肿瘤病人术后护理
随着医学的不断发展,微创手术越来越多地应用到临床,特别是对于颌面部恶性肿瘤病人来说,具有特别重要的意义.上颌窦恶性肿瘤是耳鼻喉科常见病,仅次于鼻咽癌而居第2位,治疗以手术和放疗为主[1].

颌面部爆炸伤后外形修复实验研究
Objective To study the characteristics and the way of reconstruction in maxillofacial explosive wound. Methods 30 dogs were randomly divided into 6 groups and the maxillofacial region were wounded by smoothbore barrels combined with detonators. Histological changes of soft tissue at different distance from wound track were observed after injury. At 72h post injury, 5 dogs in one group were re debrided and reconstructed. Results At 72h after wound, the soft tissue injury was the most serious. Muscles at 0~ 0.8 cm distant to the wound track were completely necrotized. The vibration area spread beyond 1.6 cm. The wounds were well healed. Conclusions The explosive injury of maxillofacial region was characterized by wide range of injury and heavily contamination. The reconstruction of soft tissue defect by vascularized gracilis flaps was effective.

颌面部恶性肿瘤根治性颈清扫术后肩部的运动训练
Background:Radical clearance of cervical lymph nodes is an effective method to treat malignant tumor of maxillofacial region and prevent diffusion and relapses. But postoperative contour and dysfunction of shoulder due to dysfunction of trapezius muscle that is caused by injury of accessory nerve affect patients' living quality.

颌面部血管性病变栓塞治疗的并发症(附13例报告)
颈外颌面部动脉造影及栓塞治疗各种血管性病变的临床意义及作用已为许多作者所肯定[1,6].由于解剖及生理的特殊性和复杂性,颌面部血管栓塞治疗的术中及术后并发症发生率较高,如不谨慎处理,将产生严重的后果.近年来,我们在对13例颌面部血管性病变栓塞治疗时,10例患者出现较明显的副反应及并发症,现报告如下.
