Cadaver studies and clinical evidence are presented to suggest that medial wall fractures are often concomitant with orbital floor fractures. The medial wall fractures are located in the ethmoid bone midway between the medial canthus and the lesser wing of the sphenoid. These fractures may be the etiology of late enophthalmus. The discrepancy between the high frequency of occurrence of medial wall fractures in this study and the rarity of clinical diagnosis derives from the limitations of standard radiography. Computed tomography (CT scan) is useful in delineating these fractures. The operative approach is through an incision above the medial canthus. Surgical treatment includes reduction of the herniated periorbital fat and coverage of the defect with autogenous, homologous, or alloplastic materials.
尸体研究和临床证据表明，眶内壁骨折常与眶底骨折同时存在。眶内壁骨折位于内眦与蝶骨小翼之间的筛骨处。这些骨折可能是晚期眼球内陷的病因。本研究中眶内壁骨折的高发生率与临床诊断的罕见性之间的差异源于标准放射摄影的局限性。计算机断层扫描（CT扫描）有助于明确这些骨折。手术入路是通过在内眦上方做切口。手术治疗包括将疝出的眶周脂肪复位，并用自体、同种异体或人工合成材料覆盖缺损。
