[Clinical effect of orbit fracture reconstruction under nasal endoscope]

To investigate the clinical effect of orbit blowout fracture reconstruction under nasal endoscope.Forty-one cases of orbit fracture were reconstructed for lost or damaged orbit under nasal endoscope through maxillary sinus, ethmoidal sinus or the both.Among the 35 cases of orbit blowout fracture, enophthalmos in 33 cases were completely improved, 29 cases were symmetrical to normal eye after operation without diplopia except that 6 cases had slight enophthalmos accompanied with slight diplopia. Among these 6 cases, 4 cases returned to normal without diplopia 6 months after operation. In the 6 cases of orbit non-blowout fracture, 4 cases were symmetrical to normal eye after operation without enophthalmos, diplopia and facial malformation. One case had slight enophthalmos and diplopia, 1 case had slight enophthalmos with slight facial malformation.The surgery under nasal endoscope is safe and credible. The method can be easily mastered and its complication is less.
