Purpose Orbital decompression and lower eyelid retraction surgery are traditionally performed separately in staged fashion, which may be unnecessary. Herein, we evaluate the safety and efficacy of combined orbital decompression and lower eyelid retraction surgery. Methods Retrospective analysis of patients undergoing combined orbital decompression and lower eyelid retraction surgery in patients with or without Graves orbitopathy, by one surgeon from 2016 to 2017. Patients with previous orbital or lower eyelid surgery were excluded. Surgical technique for orbital decompression included eyelid crease lateral-wall decompression, transconjunctival inferolateral-wall decompression, or transcaruncular medial-wall decompression, or combination. Surgical technique for lower eyelid retraction surgery described previously. Analysis included 34 surgeries (19 patients). Preoperative and postoperative photographs at longest follow-up visit were standardized and analyzed. Results Etiologies of lower eyelid retraction included thyroid eye disease (13 patients) and inherited (6 patients). Etiologies of proptosis included thyroid eye disease (13 patients) and inherited with shallow orbits and/or poor maxilla (6 patients). All 34 eyelids demonstrated improvement of lower eyelid position. The mean improvement of marginal reflex distance was 2.4 mm (range, 1.7–2.9 mm). There was one case of mild overcorrection and once case of prolonged chemosis. The average follow-up was 9 months (range, 6 months to 1 year). Conclusions This study demonstrates improvement of lower lid position in patients undergoing simultaneous orbital decompression and correction of lower eyelid retraction, irrespective of the etiology of lower eyelid retraction and proptosis or orbital decompression technique. Combined procedures may reduce the number of total procedures, patient anxiety, recovery time, and costs, without compromising the results.
