开窗减压引流术治疗巨大牙源性角化囊肿3例报告

Using fenestration and decompression technique to treat enormous odontogenic keratocyst

对3例既往需行颌骨切除的巨大角化囊肿采用开窗减压引流结合囊肿刮治的方法进行治疗。经开窗减压引流术后1.5-2a,囊肿大为缩小甚至基本消失,周围新生骨形成,颌骨形态恢复,牙功能保留,下唇无麻木。大为缩小者只需局麻下行囊肿刮除术,囊肿基本消失者残留处覆盖上皮为口腔黏膜。开窗减压引流术,结合局部刮除术是既往需截骨拔牙治疗巨大角化囊肿病例的较理想方法。

cases of enormous odontogenic keratocyst were treated with the technique of fenestration and decompression other than removal of jaws. After a follow-up period of two years, radiographic assessment showed that the image of keratocyst disappeared basically, neogenetic bone had been found and the defect of jaws had been restored. The teeth had no dysfunction, the lower lip had no numbness and the keratocyst epithelium was modulated histologically to mucosa after decompression. Fenestration and decompression are satisfied conservative approaches to treat enormous keratocyst which usually is treated by removal of jaws and extraction of teeth. [
