Abstract

Trabecular juvenile ossifying fibroma (TJOF) is a rare benign fibro-osseous tumor that may develop in the craniofacial bones at an early age. To the best of our knowledge, there is no published case of bilateral monostotic TJOF in the literature. The aim of this study was to report the surgical treatment of a rare case of bilateral mandibular TJOF in an adolescent. A 13-year-old male patient presented with no symptoms other than a slight increase in volume in the lower right facial region. Tomographic examination revealed well-defined hypodense areas, hyperdense islands, and expansion of the involved bone cortices in the posterior mandible bilaterally. After histological and immunohistochemical analysis, the diagnosis was TJOF. Using a rapid prototyping biomodel, enucleation combined with curettage and peripheral osteotomy of the tumors was performed, followed by the placement of a reconstruction plate and screws. After one year, there was a recurrence on the left side, which was treated again with curettage and peripheral osteotomy. The patient is currently under follow-up for 24 months with a favorable prognosis. Despite its aggressive potential and risk of recurrence, an individualized surgical plan should be developed. A conservative approach should be the preferred treatment, aiming to minimize deformation and functional impairment.

下颌骨双侧骨小梁幼年骨化性纤维瘤罕见病例的手术方法
骨小梁幼年骨化性纤维瘤(TJOF)是一种罕见的良性纤维骨肿瘤,可在幼年时发生于颅面骨。据我们所知,文献中尚未发表过双侧单发的 TJOF 病例。本研究旨在报告一例罕见的青少年双侧下颌骨 TJOF 的手术治疗情况。一名 13 岁的男性患者除了右下颌面部体积略有增大外,并无其他症状。断层扫描检查显示,双侧下颌骨后部有界限清晰的低密度区、高密度岛和受累骨皮质扩张。经过组织学和免疫组化分析,诊断结果为 TJOF。利用快速原型生物模型,对肿瘤进行了去核、刮除和周边截骨术,随后植入了重建钢板和螺钉。一年后,左侧肿瘤复发,再次进行了刮除和周边截骨术。目前,患者已接受了 24 个月的随访,预后良好。尽管该病具有侵袭性和复发风险,但仍应制定个性化的手术方案。保守治疗是首选,目的是尽量减少变形和功能障碍。
