骨整合义耳修复创伤性全耳廓缺损

Auricular prostheses by osseointegration technique for auricular defect after trauma

目的探讨骨整合义耳修复创伤性全耳廓缺损的可行性和临床效果。方法回顾性分析19例创伤性全耳廓缺损采用骨整合义耳修复患者。其中先天性小耳畸形全耳再造失败者12例,硫酸烧伤1例,高温铝水烫伤1例,车祸所致4例,刀砍伤1例。所有病例得到随诊,时间3～5年。结果所有患者均1次治愈,有一个形态逼真、色泽自然的外观,用骨整合方法固位的义耳配戴稳定,对日常生活无影响。结论骨整合义耳修复方法简便、创伤小、治疗周期短,无并发症,效果满意。对全耳再造失败者是一有效的治疗补救,对耳廓连同周围组织大面积缺损后瘢痕愈合者是可优先选择的方法。

OBJECTIVE To investigate the clinical results and feasibility of auricular prostheses by osseointegration technique for total auricular defect.METHODS Nineteen patients with traumatic total auricular defect who had underwent operation of bone-anchored auricular prosthesis were studied retrospectively.There were 12 cases with congenital microtia after an unsuccessful total auricular reconstruction,1 case with sulfuric acid burn,1 case with high temperature aluminum liquid burn,4 cases with traffic accident and 1 case with knife trauma.All the cases were followed-up for 3 to 5 years.RESULTS All the patients were cured after operation once.They all had vivid appearances with natural color and luster.The auricular prosthesis by osseointegration technique was stable and had no harm for daily life.CONCLUSION Auricular prosthesis by osseointegration technique is a convenient method with less trauma,short curing time,no complication and good result.It is a salvage treatment for patients after unsuccessful total auricular reconstruction.It is also a priority method for patients with scar formation after total auricular defects.
