The Climcal Observation of Treating Orbit Blow-out Fracture through Nasal Sinus with Endoscope

Purpose To study the effect of treating orbit blow-out fracture through nasal sinus with endoscope. Methods For 7 cases of inferior wall fracture of orbit combining with inferior rectus musche incarcerated,4 cases of medial wall fracture of orbit combining with medial rectus muscle incarcerated,and 1 case of inferior wall and medial well fracture of orbit companying with inferior recurs musche that fell into maxillary sinus nasal sinusal endoscope through maxillary sinus and ethmoid sinusal endoscope through maxillary sinus and ethmoid sinus were ualiged we resored the soft tissues,that fell into the sinus,and tamponed bone defect with silicagel.Results 12 cases,whose orbit soft tissue fell into nasal sinus all were reduced with the examination of CT.After following-up from 3 to 18 months,the symptom of diplopia were effaced,eye position was normal,and there was no rejection about silica gel,while Their visual acuity all increased by different degress. Conclusion Treating the orbit blowout fracture,we can utlize the methods of restoring orbit soft tissues with endoscope through maxillary and ethmoid sinus,and obviously reduce the eyeball damage.
