Abstract

OBJECTIVES:

Transconjunctival and subciliary approaches to orbital floor blowout fractures (OBF) have known risks of postoperative eyelid malposition. This study evaluates the endoscopic transmaxillary repair of OBFs in a cadaveric model and clinical setting.

METHODS:

Sixteen cadaveric and 10 clinical OBFs were repaired endoscopically. A Caldwell-Luc approach and modified sinus surgery instrumentation were used to repair each fracture. Variations in fracture pattern, instrumentation, and surgical technique were evaluated.

RESULTS:

Endoscopic repair was achieved in all 16 cadaveric orbits and in 9 of 10 patients. Fracture patterns were classified as either medial or lateral to the infraorbital nerve. Average clinical operating time was 1:38. Of 9 postoperative CT scans, 5 were rated as excellent, 3 as good, and 1 as poor.

CONCLUSIONS:

The endoscopic transmaxillary approach is a safe, viable technique for OBF repair. It offers improved visualization, anatomic fracture repair, no risk of postoperative eyelid complications, and good clinical results.
