目的：探讨开窗减压术治疗大型颌骨囊性病变的临床价值。方法：采用开窗减压术治疗大型颌骨囊性病变42例，治疗前后进行影像学检查，调查患者自行进行囊腔冲洗的频率，研究开窗减压术的疗效以及囊腔冲洗频率对治疗效果的影响。结果：患者术后3个月即可见囊腔边界模糊、体积缩小，12个月以后囊腔趋于稳定，此时可行二次手术刮除残余囊壁，此后随访1～2年无明显复发。囊腔应每天冲洗，但每天冲洗次数对疗程及疗效无明显影响。结论：开窗减压术对大型颌骨囊性病变的治疗具有明显疗效。%Objective:To investigate the clinical value of decompression in the treatment of jaw large cystic lesions.Methods:42 patients with jaw large cystic lesions were treated with decompression.Imaging examination was taken and compared before and after the treatment.The influence of frequency of cyst cavity washing on the effect of decompression was observed.Results:3 moths after de-compression the border of the cyst cavity became ambiguous and the size of the cavity reduced.12 months after decompression the size of cyst cavity was stable,when second surgery was taken to remove the left cyst wall.There was no recurrence of the cystic lesion after 1 ~2 year follow-up.Cyst cavity was washed everyday,but the effect and treatment course were not influenced by the daily washing times.Conclusion:Decompression is effective in the treatment of the jaw large cystic lesions.
