目的:探讨行硅橡胶鼻假体,矫正单侧唇裂继发鼻畸形术的护理.方法:通过延长鼻小柱,纠正鼻小柱和鼻中隔的偏斜,广泛游离患侧鼻翼软骨,分三点悬吊固定患侧鼻翼软骨,同期植入硅橡胶L型鼻假体整复单侧唇裂继发鼻畸形24例.结果:24例均一期愈合,随访3～12个月效果患者均满意.结论:采用硅橡胶L型鼻假体整复单侧唇裂继发鼻畸形,配合正确护理效果更佳.     

儿童血友病429例临床回顾分析

目的探讨血友病患儿确诊时间、症状及其关节畸形等情况。 方法天津血液学研究所血液病医院于1986年7月至2004年8月，对就诊的429例血友病患儿临床症状出现时间、诊断时间及关节畸形出现的时间进行分析。 结果429例血友病患儿，均为男性，血友病A共390例，占909%，其中亚临床型5例(13%),轻型43例(110%)，中型181例(464%)，重型161例(413%)；血友病B共39例，占91%，其中亚临床型2例(51%),轻型6例(154%)，中型26例(667%)，重型5例(128%)。患儿初次出现出血症状的中位年龄为16岁(0~12岁)；但初次诊断年龄03~120岁，中位年龄为52岁(03~120岁)，两者之间差异具有显著性意义(P<001)。 结论目前血友病患儿的诊断存在延迟，替代治疗疗程和因子剂量的不足是关节畸形高发生率的原因。     

Arthrodesis for chronic lateral subtalar joint dislocation caused by posterior tibial tendon dysfunction: A case report

IntroductionAdult acquired flatfoot deformity (AAFD) caused by posterior tibial tendon dysfunction (PTTD) can lead to the development of peritalar subluxation (PTS) and much more rarely to lateral subtalar dislocation.Presentation of caseA 75-year-old woman was referred to our hospital with an approximately 15-year history of pain in her right foot without obvious trauma. The lateral shifting foot deformity had worsened in the previous 5 years. On presentation, she had tenderness over the talonavicular joint, and the skin overlying the talar head on the medial foot was taut. Imaging revealed lateral displacement of the calcaneus with simultaneous dislocation of the talonavicular and talocalcaneal joints. We diagnosed lateral subtalar dislocation including the talonavicular and talocalcaneal joints caused by PTTD, which we treated by reduction and fusion of the subtalar joint complex. The foot and ankle were immobilized with a cast for 6 weeks.DiscussionAt the 1-year follow-up visit, the patient reported no pain during daily activities, although flatfoot persisted.ConclusionWe report a rare case of chronic lateral subtalar dislocation caused by PTTD that was treated by fusion of the talonavicular and talocalcaneal joints.

??Abstract??Objective To make doctor perform operation accurately on patients with dentomaxillofacial deformity by preoperative simulation based on digital data which was collected by digital software. Methods Fifteen patients had previously undergone 3-dimensional computed tomography and the data from CT scan were input into digital software. We used the software to simulate operations preoperatively including fixing point??osteotomies and movements of jaw bones. The collected information from software was applied to actual operations. Results All the operations had been completed successfully without serious complication. The patients were satisfied with the effect of operation 6 months after operation??with a satisfaction rate of 93.3%. Conclusion The digital simulation technique is a precise method which provides practical and effective basis for establishing the preoperative planning of individual optimal surgical procedure for patients with dentomaxillofacial deformities in orthognathic surgery.
