title: Titanium screw entered into maxillary sinus: a rare incident during rigid fixation of the porous polyethylene implant in enophthalmos correction.
abstract: Screw fixation is used for accurate augmentation by porous polyethylene implant in traumatic enophthalmos correction to avoid complications such as migration and protrusion. We report an incident of titanium screw entered into the maxillary sinus during enophthalmos correction with porous polyethylene implant. Such incident could be avoided by standard manipulation. We here present the rare case and offer proposals for the screw fixation of porous polyethylene implant during traumatic enophthalmos correction.
