Abstract

Purpose: To present the clinical outcome in 55 consecutive patients by using a customized, single-incision, 3-wall orbital decompression. Methods: A retrospective chart review was performed of 97 customized, single-incision, 3-wall decompressions in 55 consecutive patients within one surgeon's practice. A standardized surgical technique featuring lateral small-incision, 3-wall decompression with specific "strut" preservation was used in all patients. Success of the procedure was assessed on the basis of the amount of proptosis reduction achieved, as measured by the difference in Hertel exophthalmometry measurements, and by improvement in or preservation of preoperative visual acuity and color vision in the setting of compressive optic neuropathy. Subjective diplopia was recorded before and after surgery, as was the presence of extraocular muscle restriction. Results: A total of 97 orbital decompressions in 55 consecutive patients were reviewed. The majority of surgeries were performed for disfiguring proptosis with some degree of exposure-related symptoms (81%), with other indications including compressive optic neuropathy (17%), and pain (2%). The average amount of proptosis reduction achieved at 3 months was 5 mm (range, 1 to 11 mm). Visual acuity in patients with compressive optic neuropathy improved an average of 2 lines on the standard Snellen chart testing (range, 1 to 5). Color vision improved an average of 5 Ishihara plates (range, 0 to 13). Seventy-one percent of patients had subjective diplopia before surgery; 21% of these patients reported improvement or complete resolution of diplopia after surgery. Of the 29% of patients without preoperative subjective diplopia, all but one (1.8% of total patients) remained symptom free. Conclusions: We find that a customized, single-incision, 3-wall orbital decompression provides adequate decompression and proptosis reduction while minimizing postoperative strabismus and providing an aesthetically desirable result.
