Osteochondroma or solitary osteocartilagenous exostosis is characterized by cartilage-capped osseous lesion, protruding from the surface of affected bone. It is one of the most common benign bone tumor in axial skeleton and infrequent in maxillofacial skeleton. This paper describes a giant osteochondroma of coronoid process in a 20 year old woman, presented with limited mouth opening (15 mm inter incisal distance) and pain without any facial swelling, asymmetry and TMJ problems. Based on clinical examination, panoramic radiography and computed tomography images a provisional diagnosis of osteoma or osteochondroma of the coronoid process was made. Under general anaesthesia through intra oral approach excision of the bony tumor along with the coronoid process was performed, with recovery of mouth opening up to 40 mm immediately following surgery. The histopathology of excised specimen revealed features suggestive of osteochondroma. After follow up period of 54 months patient is symptom free. Here we are presenting and discussing the complete diagnostic and treatment aspect of this unusually large osteochondroma of coronoid process of mandible.
骨软骨瘤或孤立性骨软骨性外生骨疣的特征是有软骨帽覆盖的骨性病变，从受累骨表面突出。它是中轴骨骼最常见的良性骨肿瘤之一，在颌面部骨骼中较少见。本文描述了一名20岁女性的冠状突巨大骨软骨瘤，表现为开口受限（切牙间距离15毫米）且疼痛，无任何面部肿胀、不对称及颞下颌关节问题。基于临床检查、全景X线片和计算机断层扫描图像，初步诊断为冠状突骨瘤或骨软骨瘤。在全身麻醉下，经口内入路切除骨性肿瘤及冠状突，术后开口立即恢复至40毫米。切除标本的组织病理学显示为骨软骨瘤特征。经过54个月的随访，患者无症状。在此，我们展示并讨论下颌骨冠状突这种异常大的骨软骨瘤的完整诊断和治疗情况。
