摘要
目的:观察膜引导骨再生技术(guide bone regeneration,GBR)在颌骨囊肿术后对颌骨缺损修复的临床疗效。方法:小型颌骨囊肿50例,囊肿大小为1.5 cm×1.5 cm^3.0 cm×3.0 cm,均采用颌骨囊肿摘除术治疗。术中将颌骨囊肿完整摘除,确认未与鼻底及上颌窦穿通后,将人工骨粉与自体静脉血混合充填入颌骨囊肿骨缺损区,再以生物膜覆盖,常规缝合切口。结果:术后2周拆线,除5例外切口均愈合良好;术后6个月复查全景片,充填材料复合体密度与颌骨密度趋于一致;术后1年,充填材料与周围颌骨生长完全融合,不能分辨,原囊肿区可见正常的骨小梁网纹结构。结论:GBR技术对修复小型颌骨囊肿术后的局部骨质缺损安全有效。
Objective： To discuss the clinical effect of guided bone regeneration （GBR） in repairing defects after jaw cyst enucleation. Methods： 50 patients were retrospectively reviewed. After ensuring the cystic jaw defect was not communicated with nasal floor or maxillary sinus after cyst enucleation, hydroxyapatite granules and fresh human venous blood （1：l in volume） were used to fill the cyst cavity and covered with biofilm. Results： Panoramic radiography at 6- month postoperation on the density of filling materials showed convergence with the surrounding jaw bone. 12-month after operation, trabecular network structure demonstrated in the filling materials. Conclusion： GBR was safe and effective in repairing defect after jaw cyst enucleation.
