Non-displaced pediatric orbital fracture with displacement of the inferior rectus muscle into the maxillary sinus: a case report and review of the literature.

Orbital fractures occur less frequently in the pediatric population than in the adult population. Due to the elasticity of the bones that comprise the orbital floor it is not uncommon for the orbital floor to fracture and immediately self-reduce. This puts the muscles and soft tissues of the orbital floor at an increased risk of entrapment. There is no exact agreement in the literature as to the ideal timing of surgical intervention for these types of injuries. However, there are many surgeons who advise early intervention in the first few days of the injury. This article describes a case of a non-displaced orbital fracture with displacement of the inferior rectus into the maxillary sinus that was treated in the first 24 h and resulted in an excellent outcome.
