Transconjunctival Endoscopic Repair of a Trapdoor Blowout Fracture in a Child.

Even facial fractures are common in the pediatric population, and the management of blowout fractures contains various surgical methods. Here, we report a child with a blowout fracture handled with transconjunctival endoscopic repair (TCER). A 9-year-old girl was referred with complaints of left eye swelling and erythema after blunt trauma. Physical examination revealed enophthalmos, hypoesthesia in the left cheek, and restriction of left eye movements upwards and downwards. Computed tomography showed a left orbital blowout fracture with herniation of the inferior rectus muscle and soft tissue into the maxillary sinus. TCER was performed. The patient's eye movements were normal one month after surgery. TCER of the orbital floor is a minimally invasive approach with no visible scar, small incision, less trauma to the orbital tissues, and a clear view of the surgical area. It can be used as a safe and successful alternative for orbital floor repair in the pediatric population.
