下颌骨大型角化囊性瘤开窗减压术临床分析

Clinical analysis of decompression of large mandibular keratocystic odontogenic tumor

目的：探讨下颌骨大型牙源性角化囊性瘤（keratocystic odontogenic tumor,KCOT）开窗减压术临床效果.方法：对2 3例下颌骨大型角化囊性瘤开窗减压治疗,术后1周制作戴用囊腔塞治器,嘱患者餐后及睡前用温开水或生理盐水自行冲洗囊腔,随访12 ～24个月,全景片及CT检查,观察囊腔轴径的变化,评估骨腔缩小的程度.结果：23例患者经开窗减压治疗后囊腔均明显缩小,全景片示囊腔面积变小,周围有骨组织形成.总有效率为100％.结论：开窗减压术治疗大型牙源性角化囊性瘤是一种可靠、安全、有效的治疗方法,单房型角化囊性瘤疗效优于多房型.

objective To explore the clinical effect of decompression in the treatment of large mandibular KCOT. Methods 23 cases of mandibular large KCOT were performed by decompression, post-operation a week cyst plugs were made for wearing, patients were asked to clean cystic cavity with warm water or saline themselves after dinner and before going to bed. Patients were followed up for 12-24 months, observation length changes of cystic diameter by Pantomogram and CT scan, assessing the degree of bone cavity shrink. Results All 23 cases cysts significantly shrank after decompression treatment, pantomogram showed lesion size smaller, surrounding bone tissue formation. Total effective rate was 100. Conclusion Decompression of large KCOT is a kind of reliable,safe and effective method of treatment.Furthermore,among keratocystic tumor cases,curative effect of the unilocular type was superior to multilocular type.
