Abstract
The aim of this paper is to demonstrate the safety and the use of the transcaruncular approach as a surgical technique for managing a medial wall fracture. This approach was used in 40 patients with a isolated medial or a combined medial and inferior orbital wall fracture between September 1998 and September 2002. A computed tomographic scan was taken before and after surgery. The ocular motility and enophthalmos were checked before and after surgery. The transcaruncular approach provided the appropriate surgical exposure in all cases. Patients were followed up for a mean of 9.4 months (range, 5–24 months) after repairing the orbital wall fracture. Hertel exophthalmometry showed that among the 40 patients; 24 patients showed no enophthalmos. The enophthalmos ranged from 0.5–1 mm in 14 patients and 1.5 mm enphthalmos was noted in 2 patients. A clinically significant enophthalmos ≥2 mm was not found postoperatively. Preoperatively, 12 patients (30%) had a diplopia in the primary position of the gaze and 26 patients (65%) had a diplopia within 30° of the gaze. Postoperatively, all patients had an orthotropia in the primary position but 4 patients (10%) had a residual diplopia either on the lateral gaze (2 patients) or the upgaze (2 patients). There were 2 cases of an implant misplacement. The transcaruncular approach provides a safe, rapid, and cosmetically pleasing surgical approach for managing a isolated medial wall fracture. When combined with the inferior transconjunctival approach, a combined medial and inferior orbital wall fracture can be successfully repaired.
