囊肿塞子在颌骨囊肿开窗减压术中的应用

Application of cyst plugs in the marsupialization of jaw bone cysts

目的：探讨囊肿塞子在颌骨囊肿开窗减压术中的应用价值。方法选取2008年至今巨大颌骨囊肿和替牙期囊肿患者共122例，行开窗减压术后制作125件囊肿塞子（1例多发囊肿），观察效果。结果本组病例中100例患者囊腔在1-2年内闭合，包含23例9-12岁儿童，22例患者遗留一小囊腔，需二次手术，随访2年无一例复发。下颌愈合时间较上颌愈合时间短，所有混合牙列期患者恒牙均正常萌出，膨出的面型恢复正常。结论颌骨囊肿开窗减压术后佩戴囊肿塞子可以有效地阻止食物进入囊腔，引流出囊液。

Objective To investigate the application value of cyst plugs in the marsupialization of jaw bone cysts. Methods Sub-jects were 122 patients with gigantic bone cysts of the jaws and cysts in the mixed dentition since 2008,among whom one patient was with multiple cysts. All patients underwent the marsupialization,and then 125 pieces of cyst plugs were made. Results Cyst cavities of 100 patients were closed in 1-2 years,including 23 children of 9-12 years old. 22 patients had a second operation because one small cyst cavity was left after the surgery,but no cysts recurred during 2 years′ follow-up. The healing time in the mandible was shorter than that of the maxilla. Normal eruption of permanent teeth was observed for patients with mixed dentition,and the swelling face returned to nor-mal. Conclusions Cyst plugs can prevent food from flowing into cyst cavities,and guarantee the drainage of cyst fluid.
