The diagnosis of occult mandibular condylar fractures in children is often missed or delayed on initial examination when children present with a laceration to the chin. A clue to the diagnosis of this type of skeletal injury to the mandible is the knowledge of a commonly occurring pattern of injury associated with chin trauma. Chin laceration, fracture of the parasymphyseal region near the chin, and fracture of the condyles are often concomitant injuries of the mandible. This article reviews three case reports of children who sustained a chin laceration, fracture in the region near the chin, and fracture to the mandibular condyles secondary to chin trauma that were not initially diagnosed on clinical examination.
当儿童出现下巴撕裂伤时，隐匿性下颌髁突骨折在初次检查时常常被漏诊或延误诊断。诊断这类下颌骨骨骼损伤的一个线索是了解与下巴创伤相关的常见损伤模式。下巴撕裂伤、下巴附近的颏部骨折以及髁突骨折常常是下颌骨的合并伤。本文回顾了三例儿童病例报告，这些儿童因下巴创伤继发下巴撕裂伤、下巴附近区域骨折以及下颌髁突骨折，但在临床检查时最初未被诊断出来。
