开窗减压术与二期刮治后充填硫酸钙共同治疗下颌骨单囊型成釉细胞瘤12例临床观察

Clinical study of 12 cases of ameloblastoma treated with decompression with calcium sulfate implantation

目的观察开窗减压术与二期刮治后充填硫酸钙共同治疗下颌骨单囊型成釉细胞瘤的临床效果。方法对12例下颌骨单囊型成釉细胞瘤一期行开窗减压术,术后定期拍摄口腔全景片进行对比,开窗6个月至7年不等,通过二期手术刮治已缩小的单囊型成釉细胞瘤,并填充硫酸钙来达到治愈下颌骨单囊型成釉细胞瘤的目的。结果开窗术后待下颌骨单囊型成釉细胞瘤明显缩小后,行刮治术并充填硫酸钙,二期术后6个月口腔全景片可见新骨形成,原囊腔透射影像基本消失,与正常骨组织无显著差异,缺损下颌骨形态恢复良好,颌面部畸形基本改善。所有病例均未出现感染等并发症,均未出现邻近神经与重要组织的损伤。结论对于下颌骨单囊型成釉细胞瘤,采用开窗减压术与二期刮治后充填硫酸钙联合治疗可减少患者的疾苦和并发症,能更好地修复缺损下颌骨,是一种较理想的治疗方法。

Objective To value the clinical effect of ameloblastoma treated by decompression with calcium sulfate implantation. Methods 12 cases of mandibular ameloblastoma of the first phase were pereformed decompression,after the operation of a regular oral panoramic film. The time of fenestration ranged from 6 months to 7 years. The second phase surgery and calcium sulfate implantation were pereformed to cure ameloblastoma. Results After the treatment of the second phase surgery and calcium sulfate implantation,6 months oral panoramic film showed new bone formation,the original capsule cavity almost disappeared,looking like normal bone tissue. The recovery of mandibular shape was good,and the jaw deformity was improved,no infection,other complications and no nerve and important tissure damage happened. Conclusion The method of decompression and calcium sulfate implantation in the treatment of ameloblastoma can reduce complications,therefore,it is an ideal method for bone formation.
