Medial wall fracture: an update

Craniomaxillofac Trauma Reconstr. 2009 Oct;2(3):135-9. doi: 10.1055/s-0029-1224775.


This article is a review of the literature and update for management of medial orbital wall fractures. A retrospective review of the literature was performed via PubMed to review the diagnosis and management of medial wall orbital fractures. Medial wall orbital fractures though commonly accompanying orbital floor fractures can also occur alone. There are two primary theories explaining the pathophysiology of medial wall fractures: the hydraulic theory and buckling theory. Most fractures do not require treatment. "White-eyed" trapdoor fractures necessitate immediate surgery to reduce the risk of muscle fibrosis. Trapdoor fractures are more common in the pediatric population. The vast majority of nondisplaced fractures without entrapment do not require surgery. Evaluating patients with medial wall fractures requires evaluation of muscle motility and relative enophthalmos. Patients with entrapped muscles require immediate treatment to prevent permanent injury to the muscle.
