Results in Superior Oblique Sharpening in Brown Syndrome and Systemic Pediatric Diseases

The objective of this study was to evaluate and compare epidemiological factors, associated diseases, exploration and outcomes in patients with Brown Syndrome (BS) operated of superior oblique (SO) sharpening. This is a cross-sectional comparative study. 24 patients with BS operated of SO sharpening were enrolled in this study. The adduction-elevation restriction (AER), torticollis, visual acuity, treatments, trochlea triamcinolone-injections, age of surgery and systemic diseases were assessed. Fisher’s test was used to analyze if there is any association between the variables analyzed with systemic diseases. Differences between preoperative and postoperative status were analyzed using the Wilcoxon test with Bonferroni correction post hoc. We found a preoperative mean AER (0-3) was 2.88. One year after the surgery, mean AER it was 0.59 (P<0.001). Preoperative torticollis was observed in 79.1% patients. Torticollis was solved in 95.8% of cases in one year followup (P<0.001). Most common concomitant diseases were allergic asthma (12.5%), adenoid hypertrophy (12.5%), and heart murmurs (12.5%). No significant association of systemic disease with postsurgical torticollis or AER was found (P>0.05). In conclusion, SO sharpening constitutes a safe and effective surgery for BS, with fewer complications than other techniques previously described.
