Binder's syndrome: peculiarities in Japanese patients.

Abstract

We have seen 4 Japanese patients with Binder's syndrome or maxillonasal dysostosis. The diagnosis of Binder's syndrome was very difficult, based on facial appearances alone. Although the flattened nasal tip was quite unusual in Japanese individuals, the midface retrusion and flattened nasal bridge would be considered within normal limits. Consequently, the diagnosis of Binder's syndrome is only rarely made in Japanese persons. The peculiarities of this syndrome in Japanese patients are discussed and our surgical methods are shown.
