[Superior oblique sharpening in Brown's syndrome "plus". Results].
OBJECTIVE
To study the results found in patients with congenital and constant Brown's Syndrome who were surgically treated with superior oblique sharpening technique.


METHODS
Nine patients were selected among nineteen cases diagnosed of Brown's Syndrome in our Department for 4 years. Indications for surgery were vertical deviation in primary position and/or torticollis. The procedure of choice was the superior oblique sharpening in all cases, associated to its recession in 3 patients.


RESULTS
The limitation of elevation in adduction was notably marked in 100% of the cases, improving in all of them, except in one patient (11.1%) after surgery. The preoperative hypotropia presented in 7 cases (77.8%) was resolved in 5 (71.42%) after the intervention. The initial torticollis had the same incidence than the hypotropia (77.8%: 7/9), but it completely resolved in 3 cases, and improved in 3 other with this technique. Binocular vision was recovered in 2 patients. Overall, 2 out of the 9 cases (22.22%) did not clinically improve. Intraoperative and postoperative complications were not observed, except a temporary superior oblique palsy that resolved without surgery.


CONCLUSIONS
The superior oblique sharpening is a good technique which may improve the Brown Syndrome patients with primary position deviation and/or torticollis.
