Peripheral osteoma is the most common subtype of osteoma that arises most frequently in the craniofacial bones. It may occur at any age with a male-to-female ratio of 2:1. Peripheral osteoma may affect the mandible, particularly the ramus and the condyle. Compound odontoma is a subtype of odontoma that occurs in young subjects without gender predilection. It affects the maxilla more frequently than the mandible. Focal cemento-osseous dysplasia and cemento-ossifying fibroma are 2 benign fibro-osseous lesions with a female predominance that occur most commonly in the posterior region of the mandible. We report the first case involving the simultaneous occurrence of these 4 benign lesions in the same hemimandible diagnosed by CBCT.
外周骨瘤是骨瘤最常见的亚型，最常发生于颅面骨。它可发生于任何年龄，男女比例为2:1。外周骨瘤可累及下颌骨，尤其是下颌支和髁突。复合性牙瘤是牙瘤的一种亚型，发生于年轻患者，无性别倾向。它累及上颌骨比下颌骨更常见。局灶性骨 cemento-osseous 发育异常和骨化纤维瘤是2种以女性为主的良性纤维-骨病变，最常见于下颌骨后部。我们报告了首例经CBCT诊断在同一半侧下颌骨同时出现这4种良性病变的病例。
