Abstract
A case is reported blowout fracture of the orbital floor, which is successfully reconstructed with expanded polytetrafluoroethylene (ePTFE) aheet via transmaxillary approach. This 14-year-old boy presented with diplopia soon after a trauma to the region around the right eye socket sustained during a football game. Neuroimagings revealed a blowout fracture of the right floor and herniation of the inferior rectus muscle into the maxillary sinus. Forced duction of the muscle and administration of steroid and vitamin B 12 for 2 weeks without marked effect. Surgical intervention via transmaxillary route was undertaken. The herniated muscle was repositioned in the orbital cavity and the defect in the orbital floor was reconstructed and closed in 3 layer, i.e., an intraorbital ePTFE sheet, bone chips and an intramaxillary ePTFE aheet sutured to the mucous membrane of the maxillary sinus. Ocular movement has remarkablly improved after surgery. The procedure is presented and indication and timing of the operation are discussed.
