Maxillofacial osteochondromas are considered benign neoplasms, and compared with their extracranial variant are relatively rare. When they involve the mandibular condyle they can induce significant facial deformity, malocclusion and various temporomandibular joint symptoms. Complete excision is considered the standard of care, but can lead to a reduction in the height of the ipsilateral mandible with resultant complications. In such cases, reconstruction is usually warranted and may be approached in various ways. This case report demonstrates a straightforward, accurate and reproducible approach to reconstructing the TMJ, facial profile and occlusion following resection of a large TMJ osteochondroma, without the need for concomitant orthodontics.
颌面骨软骨瘤被认为是良性肿瘤，与颅外变体相比相对较少。当它们累及下颌骨髁突时，会导致明显的面部畸形、咬合不正和各种颞下颌关节症状。完全切除被认为是标准的治疗方法，但会导致同侧下颌骨高度降低，从而产生并发症。在这种情况下，通常需要进行重建，并且可以通过多种方式进行。本病例报告展示了一种直接、准确且可重复的方法，用于重建 TMJ、面部轮廓和咬合，无需同时进行正畸治疗。
