造釉细胞瘤在临床上比较多见,占颌骨牙源性肿瘤的63.2%,且80%~90%发生于下颌骨[1],造釉细胞瘤生长缓慢往往在就诊时肿瘤已侵犯大部分颌骨,已不适合行颌骨方块切除手术,单纯的保守性治疗术后复发率又高。近年来,开窗减压术日益受到颌面外科医师的关注,以其治疗角化囊肿、基底细胞痣样综合征和单囊型造釉细胞瘤可以明显缩小病变范围,恢复颌骨形态,避免颌骨切除,且术后复发率均比囊肿刮除术低[2]。行颌骨切除则可降低其复发率,但会带来面部形态改变、咀嚼功能下降、下唇麻木等并发症。在尽可能保留颌骨形态功能情况下降低术后复发率是治疗造釉细胞瘤的最终目标。
Ameloblastoma in clinical more common, accounting for 63.2% of mandibular odontogenic tumors, and 80% to 90% occurred in the mandible [1], the slow growth of ameloblastomas often at the time of treatment have been violated the large tumor Part of the jaw, jaw line is not suitable for the removal of surgery, a simple conservative treatment of recurrence rate was high. In recent years, the fenestration decompression surgery has increasingly been the concern of maxillofacial surgeons, with its treatment of keratinization cyst, basal cell nevus-like syndrome and monocystic ameloblastoma can significantly reduce the extent of the lesion, restore the jaw morphology, to avoid Jaw resection, and the recurrence rate after surgery than cyst curettage low [2]. Line jaw resection can reduce the recurrence rate, but will bring facial morphological changes, decreased masticatory function, lower lip numbness and other complications. Reducing postoperative recurrence while preserving the function of the jaw as much as possible is the ultimate goal for the treatment of ameloblastomas.
