Abstract
PURPOSE: To systematically review outcomes of orbital bony wall decompression for Grave's orbitopathy according to the surgical approach. METHODS: A systematic search for studies published in "Ovid MEDLINE", "Web of Science" and "Embase" of patients with surgical treatment of Grave's orbitopathy was performed. The overall postoperative change in Hertel exophthalmometry was calculated by random-effect meta-analysis model with 95% confidence interval (CI). RESULTS: A total of 33 studies, including 1686 patients and 2946 procedures, were included. The weighted mean Hertel value overall reduction was - 4.56 mm (95% CI - 5.05 to - 4.07 mm). According to surgical techniques the reduction was - 4.36 mm (95% CI - 5.22 to - 3.50) for infero-medial technique, - 4.88 mm (- 5.68 to - 4.08) for medial-lateral technique, - 4.32 mm (- 4.80to - 3.84) for lateral technique, - 5.45 mm (- 6.16 to - 4.74) for three-wall technique and - 3.47 mm (- 5.81 to - 1.12) for medial technique. The overall rate of new-onset of primary gaze diplopia was reported in 23 studies. The included procedures were 653 and results were heterogeneous (heterogeneity: Q = 78.8 df = 22, I2 = 72.09%, p < 0.01). The pooled proportion (95% CI) rate of new-onset of primary gaze diplopia was 12% (7-16). CONCLUSION: Our metanalysis highlights that orbital bony wall decompression represents an effective surgical procedure. The three wall approach was associated with the best results in terms of exophthalmos reduction. Data suggest that an exclusive lateral approach may help to avoid the new-onset of primary gaze diplopia during the postoperative period.
