Abstract

The membership of the Pediatric Section of the American Association of Neurological Surgeons was surveyed with regard to attitudes in current practice in the treatment of Chiari malformations Types I and II. Ninety-six of 152 (63%) valid questionnaires were returned. The median number of malformations treated yearly by the respondents was 3 for Type I and 6 for Type II. There was substantial agreement that surgery should not be carried out on asymptomatic patients and that surgery was indicated for the treatment of brain stem dysfunction, cranial nerve dysfunction, hydromyelia, and scoliosis associated with these malformations. There was substantial disagreement about lesser indications for surgery. The respondents also expressed dissatisfaction with the current classification of Chiari malformations. Chiari malformations are complex abnormalities, and their anatomy is being better delineated with magnetic resonance imaging. Carefully designed scientific clinical investigations are needed to improve our understanding and treatment of Chiari malformations.
