Superior oblique split lengthening procedure for brown syndrome, outcomes and complications.

To evaluate the outcomes of the superior oblique split tendon lengthening (SOSL) procedure for Brown syndrome (BS). At a single institution, all patients who underwent SOSL surgery for BS from 2013 to 2019 were reviewed retrospectively. We looked at the surgical outcomes and complications in a total of 20 eyes of 18 patients. The superior oblique (SO) muscle was isolated and then extended. The tendon was then split centrally into equal halves. Two 6-0 polyglactin sutures were then placed on each end of the split tendon 6-10 mm apart. To complete the Z-cut, the split tendon was cut distal to the preplaced sutures. The sutures were then tied to produce the split Z-tendon lengthening. Eleven (55%) out of 20 eyes were female patients. The mean age was 6.6 years (range 2-17 years). The mean follow-up was 26.8 months (range 5-72 months). The mean degree of preoperative limitation of elevation on adduction was -3.6±0.58 preoperatively and -0.75±1.25 postoperatively (p=0.0001). Preoperatively, the mean degree of vertical deviation at near was 3.5±7.62 and at distance was 3.10±7.84 prism diopters (PD), respectively. Postoperatively, the mean vertical deviation was 2.77±4.75 and 2.10±4.08 PD at near and distance, respectively. Postoperative complications included haematoma in one patient (5%), overcorrection in two patients (10%) and one patient required reoperation (5%). SOSL is a safe procedure that surgeons can consider in managing patients with BS. © Author(s) (or their employer(s)) 2022. No commercial re-use. See rights and permissions. Published by BMJ.
