目的探讨应用开窗联合刮切术治疗巨型壁性成釉细胞瘤的治疗效果。方法7例下颌骨巨型壁性成釉细胞瘤病例,行开窗减压引流术,引流时间6~8个月不等。期间定期复诊,拍X线全景片观察开窗减压病损缩小情况。全部病例均成骨稳定后,二期行刮切手术。结果全部病例下颌骨升支、乙状切迹、喙突膨隆处重新塑形,且保留下颌骨完整延续性。结论开窗联合刮切术能有效治疗巨型囊性壁性成釉细胞瘤。 Objective To investigate the treatment of giant ameloblasts with fenestration and fenestration. Methods Seven cases of mandibular giant ameloblastoma cases underwent open window decompression and drainage, drainage time ranging from 6 to 8 months. During regular referral, take X-ray panoramic film to observe window decompression lesion reduced. All cases were stable, the second phase of scraping surgery. Results All cases of mandibular ascending branch, sigmoid notch, beak bulging at the re-shaping, and to retain the integrity of the mandible continuity. Conclusions Open window combined with scraping can effectively treat giant cystic ameloblastoma.
