Résumé
OBJECTIVE@#To study surgical techniques and clinical applications of the intranasal endoscopic combined middle meatus and expand prelacrimal recess-maxillary ainus approach for orbital fracture treatment.@*METHOD@#A retrospective clinical analysis of 3 patients whose admitted for orbital floor fractures or medial wall fractures operated by the intranasal endoscopic middle meatus with expand prelacrimal recess-maxillary ainus approach surgical treatment was studied, and the treatment effects and the postoperative complications were analyzed.@*RESULT@#All patients had been followed up for 6 to 12 months. All cases of diplopia symptom were disappeared, enophthalmos were totally corrected, no cases of complication were found.@*CONCLUSION@#Endonasal endoscopic combined middle meatus and expand prelacrimal recess-maxillary ainus approach for orbital fracture treatment have great and clear view. This approach with less tissue damage and high therapeutic effect makes the cost lower than other methods and complications will be decreased as well, it has a great advantage in the orbital fracture treatment.
