Endoscopic- Assisted Trephination approach for repair of Frontal Sinus posterior wall fracture in a Child.

A 9 year-old male sustained multiple maxillofacial fractures after falling from a two-store building. Frontal sinuses suffered a bilateral non-displaced linear fractures extending into the anterior and posterior walls. Magnetic resonance imaging (MRI) at this time showed a small encephalocele extending into the right frontal sinus. Operative repair was performed using an Endoscopic-Assisted Trephination approach.
