摘要
目的:探讨应用颏部块状皮质骨移植矫正唇裂术后鼻翼基部低平畸形的可行性。方法:8例单侧唇裂术后伴有严重鼻部塌陷畸形患者,其中5例伴有齿槽嵴裂。除常规手术矫正鼻尖部畸形与唇部畸形外,于颏部切取约2.0 cm×0.5 cm大小块状皮质骨,以钛钉移植固定于患侧梨状孔外下缘上颌骨前壁处,恢复该处上颌骨丰满度,矫正鼻翼基部低平畸形。伴有齿槽嵴裂患者,另根据齿槽嵴裂情况,切取颏部骨质修剪成碎块后植入齿槽嵴裂区。结果:所有8例患者术后均一期愈合,鼻部塌陷畸形侧面观及底面观均明显改善。随访3个月,供受骨区伤口愈合良好,X片示钛钉及植骨块位置良好,未见明显并发症。结论:块状自体颏部骨移植手术创伤小、操作简便,整复效果可靠,是鼻翼基部低平畸形较为理想的治疗方法,具有明显的临床意义。
Objective：To study the clinical appication of mental bone grnft in anaplasty of depressed msal hase.Methods：8 patients underwent bone graft from the mental region of mandible in anaplasty of depoessed nasal hatse.The block of Lar cleft and nasal-labial defomnity were were correeted at the same time.Results：All patients achieyed satisfactory facial appearance.No obvious complication was found in the follow-up,Conclusion：Mental bone graft,for its mioor traurnam,easily operation and aestheti outcome,is grat signifieant for anaplasty of depressed nasal base.
