Osteochondroma, the most common benign tumor in the axial and appendicular skeleton, presents a unique challenge when encountered in the craniofacial region. We report a rare case of a 35-year-old female with a massive osteochondroma located on the mandibular coronoid process, resulting in a 20-year history of progressive mouth opening limitation, facial asymmetry, and zygomatic deformity. Comprehensive diagnostic procedures, including panoramic radiography and computed tomography (CT) imaging, were employed to accurately assess the extent of the lesion. This case highlights the importance of CT scans and three-dimensional reconstructions in confirming the diagnosis, particularly when panoramic radiographs exhibit limitations. The patient underwent a successful extraoral approach for coronoidectomy and excision of the osteochondroma, addressing both the functional and cosmetic aspects of the condition. Postoperative evaluations revealed significant improvement in mouth opening capacity, with no signs of recurrence during a 12-month follow-up period.
骨软骨瘤是躯干骨和四肢骨中最常见的良性肿瘤，当其出现在颅面部时会带来独特的挑战。我们报告一例罕见病例，一名35岁女性，下颌冠突处有一个巨大的骨软骨瘤，导致20年渐进性张口受限、面部不对称和颧骨畸形病史。采用了包括全景X线摄影和计算机断层扫描（CT）成像在内的综合诊断程序，以准确评估病变范围。该病例突出了CT扫描和三维重建在确诊中的重要性，尤其是当全景X线片显示出局限性时。患者通过口外入路成功进行了冠突切除术和骨软骨瘤切除术，解决了该病症的功能和美观问题。术后评估显示张口能力有显著改善，在12个月的随访期内无复发迹象。
