[Endoscopic-assisted retrocaruncular approach for management of medial orbital wall lesions: a review of 6 cases].

BACKGROUND
Medial wall orbital fractures can result from external trauma (midfacial trauma, blow out) or from endonasal trauma (functional endoscopic sinus surgery). Entrapment of the medial rectus muscle can lead to optical complications if not treated (restriction of ocular mobility, diplopia). Enophtalmos can also be the result of extrusion of orbital fat into the ethmoïdal cavities. Surgical repair entails treatment and prevention of these complications.


OBJECTIVE
Define the contribution of endoscopy and retrocaruncular incision, particularly in terms of accessibility and visibility of the posterior third of the medial wall of the orbit.


MATERIAL AND METHODS
Six patients with medial orbital wall fractures were treated between May 2006 and May 2007 using a retrocaruncular approach assisted peroperatively by endoscopy. No complications occurred during the postoperative follow up. The authors describe the surgical techniques used.


CONCLUSIONS
Retrocaruncular approach is a safe and effective technique that presents the particular advantage of not leaving a dysesthetic scar. Peroperative endoscopy allows then a better accessibility and visibility of the posterior third of the medial orbital wall.
