Orbital decompression for dysthyroid eye disease is traditionally performed either through an external approach or transantrally. The introduction of endoscopic sinus surgery over the last decade has led to a better understanding of the intranasal surgical landmarks of orbital walls and the development of endoscopic orbital decompression. We have adopted the endoscopic technique as the treatment of choice for orbital decompression in dysthyroid eye disease for the last two years. The surgical technique is described and illustrated, and the results of our first series of 15 patients (30 orbits) are presented.
