title: Surgical results in Brown syndrome.
abstract: Surgical treatment for Brown superior oblique tendon sheath syndrome, now called Brown syndrome, has been advocated for patients with abnormal head posture or manifest hypotropia in primary gaze. Several surgical procedures with variable results and complications have been reported without consensus. Techniques and results of treatment for Brown syndrome at two institutions were reviewed. Charts of all patients who had undergone surgical treatment at Texas Children's Hospital, Houston, Tex, and Riley Hospital for Children, Indianapolis, Ind, between 1965 and 1989 were reviewed. The review yielded 38 patients. Superior oblique tenectomy was the most efficacious initial procedure. Surgery was successful in the treatment of anomalous head posture associated with Brown syndrome. There was no loss of sensory function as a result of surgery, but surgery did not inevitably lead to improved sensory function. We do not advocate superior oblique weakening combined with simultaneous surgery for iatrogenic superior oblique palsy as an initial procedure for Brown syndrome, since nearly one-half of our patients did not develop superior oblique palsy when followed for more than 1 year.
