Fractures of the medial infraorbital rim may occur independently or in conjunction with fractures of the nose and zygoma. Infraorbital fractures are frequently associated with anesthesia in the distribution area of infraorbital nerve and can produce palpable "step-off" deformities. Because roentgenographic and clinical indications of these fractures are often subtle, such injuries may go unrecognized in the presence of more obvious nasal fractures or may be misdiagnosed as "tripod" fractures. A proper recognition of these fractures is necessary for correct diagnosis and treatment. Three cases are presented and seven cases are summarized.
眶下缘内侧骨折可单独发生，也可与鼻骨和颧骨骨折同时出现。眶下骨折常伴有眶下神经分布区域的感觉麻木，并可产生可触及的“台阶样”畸形。由于这些骨折的X线表现和临床体征往往不明显，在存在更明显的鼻骨骨折时，此类损伤可能未被识别，或可能被误诊为“三脚架”骨折。正确识别这些骨折对于正确的诊断和治疗是必要的。本文报告3例并总结7例。
