An osteochondroma, when reported in the maxillofacial region, is a benign neoplasm that involves the skull base, maxillary sinus, zygomatic arch, or mandible. Most commonly, the osteochondroma occurs in the coronoid process and the condyle. One rare subtype of osteochondroma reported in the literature, termed Jacob disease, arises from the coronoid process and interferes with the zygomatic arch. This report describes a unique case of an isolated osteochondroma arising from the zygomatic arch and interfering with the coronoid process, which was treated through surgical excision by an intraoral approach. The literature search indicated that this is 1 among only 9 other reported cases since 1964 in which an osteochondroma arose primarily from the zygomatic arch.
骨软骨瘤发生于颌面部时，是一种累及颅底、上颌窦、颧弓或下颌骨的良性肿瘤。最常见的是，骨软骨瘤发生于冠状突和髁突。文献中报道的一种罕见的骨软骨瘤亚型，称为雅各布病，起源于冠状突并累及颧弓。本报告描述了一例独特的孤立性骨软骨瘤，起源于颧弓并累及冠状突，通过口内入路手术切除进行治疗。文献检索表明，自1964年以来，这是仅有的9例其他报道病例中的1例，其中骨软骨瘤主要起源于颧弓。
