牙源性颌骨囊性病变行开窗减压术与刮治术的疗效比较

目的探讨不同术式治疗牙源性颌骨囊性病变的临床疗效。方法回顾分析我院2012年1月—2015年1月收治的144例牙源性颌骨囊性病变患者的临床资料,A组行开窗减压术治疗,B组行完整刮治术治疗。采用SPSS18.0及PEMS3.1软件中的t检验、χ2检验以及Radit检验,比较2组手术及术后情况的差异。结果A组患者的手术时间为（36.3±5.7）min,显著少于B组;A组术后疼痛或麻木发生率、术后创腔感染率、术后3年复发率分别为5.45%、0%、3.64%,均显著低于B组（P<0.01）;A组患者术后3个月、6个月囊腔面积减少平均百分率均显著高于B组（P<0.01）;术后6个月,A组患者总有效率为98.18%,B组为84.27%,A组显著高于B组（P<0.01）。结论对于大型牙源性颌骨囊性病变患者采取开窗减压术疗效显著,创伤小、复发少,安全性高,值得临床推广应用。

Comparison of clinical effect between odontogenic jaw cystic lesions undergoing open window decompression and curettage

PURPOSE: To compare the clinical effect of decompression and curettage in treatment of odontogenic jaw cystic lesions. METHODS: The clinical data of 144 patients with odontogenic jaw cystic lesions treated from January 2012 to January 2015 in our hospital were retrospectively analyzed. Patients in group A were treated by open window decompression, while patients in group B were treated with complete curettage. Treatment outcomes and complications in 2 groups were compared with SPSS18.0 and PEMS3.1 software package. RESULTS: The operation time of group A was (36.3±5.7) min, significantly lower than that B; The incidence of postoperative pain or numbness, wound infection, recurrence were respectively 5.45%, 0% and 3.64%, significantly lower than those in group B(P<0.01); The average percentage of lesion shrinkage in group A 3 months, 6 months after operation were significantly higher than in group B (P<0.01). The total effective rate 6 months after surgery was 98.18% in group A, 84.27% in group B (P<0.01). CONCLUSIONS: For patients with large odontogenic cystic lesions, open window decompression is an efficacious, it is modality of less trauma, less recurrence and high safety, which is worthy of clinical application.
