[Clinical effect of orbit fracture reconstruction under nasal endoscope].

Objective: To investigate the clinical effect of orbit blowout fracture reconstruction under nasal endoscope.

Methods: Forty-one cases of orbit fracture were reconstructed for lost or damaged orbit under nasal endoscope through maxillary sinus, ethmoidal sinus or the both.

Results: 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.

Conclusions: The surgery under nasal endoscope is safe and credible. The method can be easily mastered and its complication is less.
