dc.description.abstractPURPOSE To study the suitability of an endoscopic transcaruncular approach (ETA) for repair of large medial orbital wall fractures (MOWFs) near the orbital apex. DESIGN A retrospective, noncomparative case series with description of the surgical technique. PARTICIPANTS Ninety-three consecutive patients (93 orbits) with large isolated MOWFs near the orbital apex. METHODS The isolated MOWFs were determined by computed tomography (CT) scans of the orbit in all patients. All patients underwent fracture repair by an ETA, and the vertical and horizontal dimensions of the defects were measured during surgery. Porous polyethylene sheets (1.0 mm thick) were used to repair the bony defects. Patients were followed for 6 to 15 months. MAIN OUTCOME MEASURES Size of vertical and horizontal fracture defects, rate of complete repair of the fracture defects, correction of enophthalmos, resolution of diplopia, and complications 6 months after surgery. RESULTS All surgeries were completed uneventfully. The mean postoperative follow-up time was 9.7±3.0 months. Under direct endoscopic visualization, all entrapped and herniated orbital contents were released and reposited, the entire boundary of the fractures were exposed adequately, and the implants were placed to overlie all edges of the fracture stably in all cases. The vertical and horizontal fracture defects measured during surgeries ranged from 16 to 30 mm and from 25 to 34 mm, respectively. Six months after surgery, complete reconstruction of the bony defects was demonstrated by orbital CT scans, and symmetry of the both eyes was acquired in 92 of 93 patients (98.9%). Of 30 patients with significant preoperative enophthalmos of more than 2 mm, 29 (96.7%) were corrected, with a mean improvement of 3.37±0.77 mm. Diplopia within the 30° visual field of the gaze was resolved in 40 of 43 patients (93.0%). Three patients (7.0%) had residual diplopia on medial gaze because of presumed paralysis of the medial rectus muscle. Intraorbital hemorrhage occurred in 1 patient the day after surgery and resolved with conservative treatment. CONCLUSIONS The ETA seems to be a useful method for recovery of the normal anatomic features of the orbits for patients with large MOWFs near the orbital apex.en
