应用螺旋CT三维重建鼻骨形态鼻内镜下歪鼻矫正术

摘要

目的 探讨应用螺旋CT三维重建鼻骨形态鼻内镜下矫正歪鼻畸形的手术治疗方法.方法 对66例歪鼻畸形患者术前行螺旋CT三维重建鼻骨形态,了解歪鼻畸形的局部形成状况.先在鼻内镜下行鼻中隔偏曲的矫正术,后经鼻前庭前小切口在鼻内镜辅助下行歪鼻畸形矫正.结果 术后1周、1个月、3个月及半年后随访,观察外鼻形状,并测量其偏离值.66例歪鼻中矫正效果优为53例,良好为11例,不满意2例.结论 螺旋CT三维重建鼻骨形态可在术前充分了解歪鼻畸形局部及周围情况;采用鼻内镜能充分暴露骨折畸形愈合部位,避免破坏整体框架,使得手术创伤小,手术时间短,术后反应轻,皮肤坏死可能性减小等,因此应用螺旋CT三维重建鼻骨形态鼻内镜下矫正歪鼻畸形效果更具优势.%Objective To discuss the endoscopy-assisted surgery for deviated nose with the preoperative 3-D CT reconstruction. Methods Sixty-six cases with deviated nose deformities underwent preoperative 3-D CT reconstruction. The deformities were showed in detail. The deviated nasal septum and deviated nose were corrected with the assistance of nasal endoscopy. Results The patients were visited after operation at 1 week, 1 month, 3 months and 6 months. The nose shape and nose deviation were measured. Among the 66 cases, satisfactory result was achieved in 53 cases, good in 11 cases,unsatisfactory in 2 cases. Conclusions Preoperative CT reconstruction is very help in understanding the deviated nose deformity. The rhinoplasty with nasal endoscopy has good exposure of the fracture deformity with less morbidity and side effect. The intraoperative time can be decreased also.
