AIM: To analysis the mechanism, clinical peculiarity, and treatment for pediatric orbital blowout fracture.

METHODS: The retrospective analysis included 12 pediatric patients suffered from orbital blowout fracture from 2008-2010.

RESULTS: Of the 12 pediatric patients, most of the orbital blowout fractures were located in orbital floor when the patients fell over. Diplopia occurred and embedded musculi were observed by CT. Early interventions were taken. Diplopia improved in all of the 12 pediatric patients. One week after surgery, eye movements in 6 patients became normal gradually; 4 patients' muscle recuperated in 3 months; 2 patients couldn't move their eyes normally within 6 months and traction tests were positive.

CONCLUSION: The pediatric orbital blowout fracture more often happen in floor orbital and cranny blowout is their configuration. Restricted movement and diplopia are main signs. Enophthalmos occurs rarely. Trauma and operation both can cause muscle's hurt. Early intervention usually led to better improvement and more complete resolution of ocular motility limitation and diplopia than late repairs.
