	abstract = {PURPOSE: To determine incidence of new-onset diplopia, resolution of preexisting diplopia, and impact on proptosis resulting from endoscopic orbital decompression with and without preservation of the inferomedial orbital strut for thyroid orbitopathy. METHODS: Retrospective review of all patients undergoing endoscopic 2- or 3-wall decompression with or without preservation of the strut for thyroid orbitopathy from January 2012 to June 2015. RESULTS: Twenty-six patients (45 orbits) were included and divided into 4 primary categories: 2-wall decompression with strut preservation (4 orbits, 8\%), 2-wall decompression with strut removal (7 orbits, 16\%), 3-wall decompression with strut preservation (27 orbits, 60\%), and 3-wall decompression with strut removal (7 orbits, 16\%). The incidence of new-onset diplopia was 20\% (2/10 patients without preoperative diplopia) overall and 16\% in the strut preservation group (1/6 patients without preoperative diplopia). Resolution of diplopia occurred in 4 of 16 patients (25\%) with preoperative diplopia, and all 4 had been treated with a 3-wall decompression with strut preservation. Resolution of diplopia in the group treated with strut preservation was 36\% (4/11 patients with preoperative diplopia), and 0\% of the 5 diplopic patients treated without strut preservation. Reduction in proptosis was statistically greater in those treated with strut removal (p = 0.003). CONCLUSIONS: This study demonstrates that endoscopic orbital decompression with preservation of the inferomedial bone strut results in a comparable to lower rate of new-onset diplopia compared with other reported techniques. When combined with 3-wall balanced decompression, this technique demonstrates a high rate of resolution of preexisting diplopia.},
