Inferolateral marginal orbitectomy: a simple adjuvant technique for orbital decompression.

The number of patients with mild exophthalmos, without severe eye symptoms, who wish to undergo aesthetic orbital decompression, is increasing. Removal of the lateral and inferior orbital walls is a common procedure for mild to moderate exophthalmos. However, the limited space between the globe and the orbital wall is often troublesome for surgeons introducing surgical devices. As a result, the decompression tends to be insufficient in the posterior region of the orbit. We describe a simple adjuvant surgical technique to address this limitation. Through a laterally extended, transconjunctival approach, the inferior and lateral margins of the orbit are removed in a crescent shape before the actual decompression. This manoeuvre widens the working space and offers better visibility, enabling sufficient removal of the orbital walls. The technique presented facilitates the approach to the posterior regions of the orbit, enabling surgeons to more easily perform orbital decompression.
