Brown syndrome surgical treatment: A comparison of three superior oblique techniques: Cross-sectional study.

There were 76 male patients and 98 female patients with a mean age of 13.34 ± 5.47 (6-35 years).

Fifty-two patients received superior oblique nasal tenotomy, 56 received superior oblique temporal tenotomy, and 66 received superior oblique tendon elongation.

Of the 36 patients (20.7%) who had a vertical deviation rate at the 1-year follow-up, 20 underwent the second procedure (superior oblique temporal or nasal tenotomy for hypotropia and inferior oblique anterior transposition for hypertropia), and two underwent the third procedure (inferior oblique anterior transposition for hypertropia).
