Aneurysmal bone cysts are relatively uncommon in the facial skeleton. These usually affect the mandible but origin from the coronoid process is even rarer. To the best of our knowledge, this is the first reported case of a coronoid process aneurysmal bone cyst presenting as temporal fossa swelling.
A 17 year old boy presented with a progressively increasing swelling in the left temporal region developed over the previous 8 months. An expansile lytic cystic lesion originating from the coronoid process of the left mandible and extending into the infratemporal and temporal fossa regions was found on CT scan. It was removed by a superior approach to the infratemporal fossa.
Aneurysmal bone cyst of the coronoid process can attain enormous dimensions until the temporal region is also involved. A superior approach to the infratemporal fossa is a reasonable approach for such cases, providing wide exposure and access to all parts of the lesion and ensuring better control and complete excision.
动脉瘤样骨囊肿在面颅骨中相对少见。这些囊肿通常累及下颌骨，但起源于冠突的情况更为罕见。据我们所知，这是首例报道的以颞窝肿胀为表现的冠突动脉瘤样骨囊肿病例。
一名17岁男孩，在过去8个月中左侧颞部肿胀逐渐加重。CT扫描发现一个膨胀性溶骨性囊性病变，起源于左下颌骨冠突并延伸至颞下窝和颞窝区域。通过颞下窝上方入路将其切除。
冠突动脉瘤样骨囊肿在累及颞区之前可长得很大。颞下窝上方入路对此类病例是一种合理的方法，可提供广泛暴露并进入病变的各个部位，确保更好的控制和完整切除。
