Pseudo-Duane’s Retraction Syndrome Associated with Medial Wall Trapdoor Orbital Fracture

Abstract

Trapdoor orbital fractures are uncommon and tend to occur in children and young adults. Medial orbital wall fractures with associated incarceration of the medial rectus muscle have been reported as the most common cause of pseudo-Duane’s retraction syndrome. We report a case of a 10-year-old patient with isolated medial wall trapdoor orbital fracture with right medial rectus muscle entrapment visible on the CT scan. The patient complained of nausea and vomiting especially with abduction of the right eye and showed signs of pseudo-Duane’s syndrome. It was satisfactorily resolved via a transcaruncular approach.
