The clinical features and treatment of orbital blowout fracture

Objective: To evaluate the clinical features and treatment of orbital blowout fracture.Methods: 32 eye of 32 cases with orbital blowout fractures associated with diplopia and eye movement disorders in our hospital were reviewed retrospectively.Orbital CT display extraocular muscles and orbital soft tissue were incarcerated into medial wall or orbital floor fracture zone.After 2 weeks observation,there was no significant improvement with diplopia and eye movement disorders.Under general anesthesia,Infraorbital incision,inner canthal skin incision or combined incision was done according to the orbital wall fracture site.Incarcerated tissues in maxillary sinus were replaced.The appropriate Medpors were implanted according to the size of the fracture.Followed up from 3 months to 1 year.Results: Eye movement in 23 cases were normal.9 patients still suffered from diplopia.Enophthalmos in 23 cases were fully restored.Conclusions: Diplopia and enophthalmos were main complains in orbital blowout fracture patients.CT scans and traction test clearly displayed incarcerated extraocular muscles.Operation must be done after 2 weeks obversation without improvement.
