目的通过开窗联合刮除术治疗下颌骨巨型囊性成釉细胞瘤,探讨其在保存下颌骨外形及功能的应用价值。方法对12例下颌骨巨型囊性成釉细胞瘤患者行开窗减压引流术,引流时间6～8个月。期间定期复诊,拍X线全景片观察开窗减压后下颌骨的病损缩小情况。全部病例均在成骨稳定后二期行刮除术。结果全部病例均痊愈,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。结论开窗联合刮除术能有效治疗下颌骨巨型囊性成釉细胞瘤,具有创伤小、手术时间短、术后并发症少、临近牙齿及骨组织及下牙槽神经血管损伤概率小等特点。
Objective To treat the maxillary ameloblastoma of mandible by coalescing with fenestration and to explore its application value in preserving mandible shape and function. Methods A total of 12 patients with giant cystic ameloblastoma underwent open window decompression and drainage, drainage time of 6 to 8 months. Period of regular referral, take X-ray panoramic film observation mandibular lesion reduction after fenestration decompression. All cases were in the second phase of osteogenic stable curettage. Results All the cases were healed, mandibular ascending branch, sigmoid notch, beak bulging at the remodeling, and to retain the integrity of the mandible continuity. Conclusions The combined fenestration and curettage can effectively treat the maxillary ameloblastoma of the mandible with the advantages of less trauma, shorter operative time, less postoperative complications, less odontogenic injury to the teeth and bony tissues and lower alveolar nerve injury .
