Medpor(R)-using Reconstruction of the Orbital Floor Defect Caused by the Maxillary Sinus Mucocele: A Case Report

• Rhyoo C

Abstract

Mucoceles of the paranasal sinuses are benign, locally expansile cysts filled with mucus and lined by the mucoperiosteum of the involved sinus. Orbital symptoms are characteristic in symptomatic maxillary sinus mucoceles, and patients initially consulted ophthalmologists for eyeball displacement, diplopia, proptosis, enophthalmos, epiphora, and rarely decreased visual acuity. Recently, we experienced a case of maxillary sinus mucocele with the destruction of the orbital floor. The mucocele was treated by marsupialization via intranasal and transantral approach, and the large defect of orbital floor was successfully reconstructed using high-density porous polyethylene (Medpor(R), Porex Surgical Inc, College Park, GA). Accurately positioned Medpor implant was observed in the orbital floor after 48 months postoperatively.
