摘要
目的观察对下颌骨大型牙源性角化囊性瘤采用一期开窗减压术联合二期刮治术术后骨腔的影像学改变,探讨该术式的可行性。方法下颌骨大型牙源性角化囊性瘤16例,进行一期开窗减压术联合二期刮治术治疗,定期复查曲面断层X线片,观察骨腔的改变。结果经过8～16个月的观察,所有患者一期手术后病变骨腔逐渐向开窗部位缩小,骨腔密度逐渐增高,最终在开窗部位形成小骨腔;二期手术后约3个月,病变区骨密度与正常下颌骨一致。随访3～8年,所有病例均未见复发。结论一期开窗减压术联合二期刮治术是治疗大型下颌骨牙源性角化囊性瘤的可行术式。
Objective To explore the feasibility of decompression tbr large mandibular keratocystic odontogenic tumors by observing the imaging changes ＇after the operations. Methods The changes of the bone cavity were observed by regular X-ray examination in 16 patients with large mandibular keratocystie odontogenic tumors ＇after the operations of decompression and curettage. Results Atier 8-16 months observation, the hone cavity became smaller gradually and fi- nally to a little cavities in the sides of the decompression, the gradually raising of the bone cavity densities were seen, the density of the lesion became similar to the normal mandibles 3 months later af^er the second stage operations. Conclusion The decompression with the secoml stage curettage was a feasible operation h^r large mandibular keratocystic odontogenic tumors.
