RESUMO
BACKGROUND: The main treatment for the symptoms of proptosis and optic nerve compression caused by thyroid-associated ophthalmopathy is orbital decompression surgery. Medial inferior wall decompression and balanced decompression are two frequently used surgical procedures. However, there is no unified consensus on how to choose different surgical options for orbital decompression in clinical practice. AIMS: To compare the effects of medial inferior wall decompression and balanced decompression surgery through meta-analysis and to provide reference for clinical optimal decision making. METHODS: Databases, including PubMed, Web of Science, Ovid, Cochrane Library, and ClinicalTrials.gov, were searched for randomized controlled trials and cohort studies on decompression surgery for thyroid-associated ophthalmopathy published from inception to March 21, 2023. Using RevMan 5.3 software, a meta-analysis was conducted based on the following outcome indicators: proptosis, diplopia rate, intraocular pressure, visual acuity, and complication rate. RESULTS: Two randomized controlled trials and five cohort studies with a total of 377 patients were included in this analysis. After balanced decompression surgery, patients with thyroid-associated ophthalmopathy experienced a significant decrease in proptosis [MD = 4.92, 95% CI (4.26, 5.58), P < 0.0001]. Balanced decompression can improve postoperative visual acuity [MD = - 0.35, 95% CI (- 0.56, - 0.13), P = 0.001] and intraocular pressure [MD = 5.33, 95% CI (3.34, 7.32), P < 0.0001]. The rates of proptosis [MD = 0.33, 95% CI (- 1.80, 2.46), P = 0.76] and diplopia [OR = 1.20, 95% CI (0.38, 3.76), P = 0.76] did not differ between patients who underwent medial inferior wall decompression and those who underwent balanced decompression. CONCLUSION: Balanced decompression and medial inferior wall decompression are both effective options for surgical treatment of thyroid-associated ophthalmopathy in clinical practice.
