Reconstruction of orbital floor fracture using porous polyethylene mesh

Abstract

Objective: Treatment of traumatic orbital injury has long been a formidable challenge to maxillofacial and oculoplastic surgeon. Significant complication can occur as a result of these injuries including enopthalmus, persistent diplopia, vertical dystopia and restriction of gaze. Surgical techniques have been more aggressive with primary surgical repair directed at restoring bony orbital volume and contour while repositioning the herniated tissues. The study was undertaken to assess the treatment results with alloplastic graft for reconstruction of orbital floor. Material and methods: It is a prospective randomized study during the period of January 2010 to December 2012 including the follow up of six months on ten orbital floor fractures. Results: Eyeball movement restriction and infraorbital nerve paresthesia improved in all patients. One patient who also had associated head injury and the fracture of supraorbital rim, frontal and temporal bone had persistent enopthalmus, vertical dystopia and diplopia postoperatively. Conclusion: We conclude that early exploration of orbital floor minimizes the morbity associated with late reconstruction due to the fibrosis of tissues entrapped. Use of prolene mesh reduces the operating time and donor site morbidity.
