成釉细胞瘤是一种良性但局部侵袭性的牙源性肿瘤，主要发生在颌骨。成釉细胞瘤可能很难诊断，因为它模仿其他良性病变。其诊断需要结合影像数据、组织病理学分析和分子测试。其治疗方式从简单的骨剜除术到广泛的手术切除不等。 一名 25 岁女性，因右侧下颌肿块就诊五年。组织病理学和放射学测试证实其为成釉细胞瘤。进行了半下颌骨切除术，然后使用自体插入的髂嵴骨和肋软骨移植物作为丢失部分的插入移植物立即进行重建。该患者的临床结果令人满意，六个月随访后没有复发迹象。理想的成釉细胞瘤治疗应尽量减少复发，恢复功能和外观，并尽量减少供区发病率。虽然切除大部分骨骼和软组织会导致缺陷，从而可能引起功能和美观问题，但保守治疗会缩短停机时间，但复发率较高。重建手术对于恢复这些患者丢失的部位至关重要。根治性手术是大肿瘤的首选治疗方法，可以最大限度地减少复发，而利用移植技术立即重建对于恢复功能和外观至关重要。自体骨移植技术对于即刻下颌重建来说是令人满意的，因为它代表了一种简单、容易、成本较低且可靠的恢复下颌连续性缺损的方法。版权所有 © 2024 作者。由爱思唯尔有限公司出版。保留所有权利。

Ameloblastoma is a benign but locally aggressive odontogenic tumor mostly occurring in the jaws. Ameloblastoma can be difficult to diagnose because it mimics other benign lesions. Its diagnosis requires a combination of imaging data, histopathological analysis, and molecular tests. Its treatment modality diverges from simple enucleation with bone curettage up to wide surgical resections.A 25-year-old female presented with a right-sided mandibular mass for five years. Histopathology and radiology tests confirmed it to be an ameloblastoma. A hemimandibulectomy was done, followed by immediate reconstruction using an autogenously inserted iliac crest bone and a costochondral graft as an interposition graft for the lost part. The patient had a satisfactory clinical outcome, and no sign of recurrence after a follow-up of six months.The ideal management of ameloblastoma should minimize recurrence, restore function and appearance, and present minimal donor site morbidity. While the removal of a wide part of the bone and soft tissue leads to defects that may cause functional and aesthetic concerns, conservative management is associated with minimal downtime but high recurrence rates. Reconstructive surgery is of paramount importance for the recovery of the lost parts in these patients.Radical surgery is the treatment of choice for large tumors to minimize recurrence, and immediate reconstruction utilizing grafting techniques is essential to restoring function and appearance. The autologous bone graft technique is satisfactory for immediate mandibular reconstruction as it represents a simple, easy, less costly, and reliable method for restoring mandibular continuity defects.Copyright © 2024 The Authors.
