This report has illustrated the variety of temporal bone fractures that involve the zygomatic, squamous, and petromastoid components of the temporal bone. Complications as they relate to each type of fracture have been emphasized. Although longitudinal and transverse fractures can be identified, temporal bone trauma usually creates unique fractures constellations that must be individually described. In each case, a careful inspection of the ossides, otic capsule (vestibule/cochlea), internal auditory, and facial nerve canal must be undertaken. When a patient presents with temporal bone fracture and facial nerve paralysis, identification of the site of facial nerve injury may now lead to surgical decompression of this area of the facial nerve canal and possible nerve grafting.
本报告阐述了累及颞骨颧突、鳞部和岩乳突部的各种颞骨骨折。重点强调了与每种骨折类型相关的并发症。虽然可以识别纵行骨折和横行骨折，但颞骨创伤通常会造成独特的骨折组合，必须分别进行描述。在每种情况下，都必须仔细检查听小骨、耳囊（前庭/耳蜗）、内耳道和面神经管。当患者出现颞骨骨折和面神经麻痹时，确定面神经损伤部位现在可能会促使对面神经管的该区域进行手术减压以及可能的神经移植。
