Two Cases of Orbital Blowout Fractures with Extraocular Muscle Entrapment in Children

Orbital blowout fracture is a common result of facial trauma and with the expanded use of endoscopy in orbital blowout fracture surgery, otolaryngologists are participating more often blowout fracture surgery. Because orbital blowout fracture may result in sequelae such as diplopia and enophthalmos, proper diagnosis and timing of repair are crucial. Orbital blowout fracture with extraocular muscle entrapment is uncommon and almost exclusively seen in children. It needs emergent release of entrapped muscle to prevent permanent sequelae (e.g., diplopia). The authors experienced two cases of orbital blowout fracture with extraocular muscle entrapment and had good surgical results without any sequelae. We report these cases with a review of the literature.
