Methods All 6 cases had endophthalmos and blepharophimosis. Four cases also complained of diplopia. The horizontal and coronal CT of orbit showed the lamina papyracea fracture clearly.The degree and range of the lamina papyracea displacement was measured on CT films.The reduction under nasal endoscope was performed with local and topical anesthesia. We selected the Meeserklinger＇s route of entry.The uncinate process,ethmoidal bulla,and ethmoidal cells were removed successively.Then,with the help of a tonsil dissector, the lamina papyracea was pushed outward and replaced and was supported with iodoform gauze.After 2 to 3 weeks,the gauze was removed.
