Parry-Romberg syndrome: an unusual case of lagophthalmus and exposure keratopathy

•Parry-Romberg syndrome (PRS) is a rare degenerative disorder.•We present a case of PRS complicated with lagophthalmus and corneal ulceration.•The orbit was reconstructed using a myofascial flap, iliac crest, and cranial bone grafts.•Reconstruction led to resolution of the ocular injuries.

Parry-Romberg syndrome (PRS) is a poorly understood degenerative disease characterized by atrophy affecting one side of the face. In this report, we describe a patient with PRS associated with exposure keratopathy and corneal ulceration as a result of lagophthalmos. The clinical findings and staged composite reconstruction are described.
