Abstract

This case report aimed to describe a rare benign mandibular tumour and assess the outcomes of the most recent reviews, between January 2017 and August 2023. Presenting a detailed clinical case, this study advances our understanding of the diagnostic and therapeutic aspects, ultimately improving the management of similar cases in clinical practice. Orthopantomogram (OPG) revealed a well-defined unilocular radiolucency extending from the midline of the ramus and teeth 47 and 48 were submerged at the base of the mandible. In the presented case, a PLANMECA ROMEXIS PROMAX® three-dimensional (3D) maximum (MAX) cone-beam computed tomography (CBCT) device was used for the 3D examination. An intraoral approach was preferred and the tumour was removed in toto by creating a bone window using a W&H® Dentalwerk Bürmoos GmbH Piezomed piezoelectric device, and the bone plates were fixed with 4 MEDARTIS® microplates, with a primary flap closure. A PANORAMIC 1000, 3DHISTECH Ltd® device was employed for the histological investigation. Odontogenic tumours are rare and typically asymptomatic, often discovered incidentally during routine radiographic examinations. Most of these benign lesions heal well after complete excision and require long-term follow-up. Once diagnosed, ameloblastic fibroma (AF) should be treated immediately to avoid malignant transformation.

摘要

本病例报告旨在描述一种罕见的良性下颌骨肿瘤,并评估 2017 年 1 月至 2023 年 8 月期间最近的综述结果。通过详细的临床病例,本研究提高了我们对诊断和治疗方面的认识,最终改善了临床实践中类似病例的管理。口腔全景片(OPG)显示从中线支延伸的清晰定义的单房性透亮区,并且牙齿 47 和 48 被淹没在下颌骨的底部。在本病例中,使用了 PLANMECA ROMEXIS PROMAX®三维(3D)最大(MAX)锥形束计算机断层扫描(CBCT)设备进行 3D 检查。选择了口内入路,使用 W&H® Dentalwerk Bürmoos GmbH Piezomed 压电设备创建骨窗,整块切除肿瘤,并用 4 个 MEDARTIS®微型板固定骨板,并进行一期皮瓣闭合。使用 3DHISTECH Ltd®的 PANORAMIC 1000 设备进行组织学研究。牙源性肿瘤罕见,通常无症状,常在常规放射学检查中偶然发现。这些良性病变大多数在完全切除后愈合良好,需要长期随访。一旦诊断为成釉细胞瘤(AF),应立即进行治疗,以避免恶性转化。
