Bicoronal Synostosis
Introduction Craniosynostosis |
Bicoronal suture fusion results in a flat retruded forehead with
increased height to the skull. This condition is also called
brachycephaly due to the short anteroposterior diameter. As a result of
this shortening there is a compensatory bulging of the transverse
diameter or width of the skull. The brow is usually recessed and
elevated with the deformity being symmetric. The incidence of bicoronal
synostosis or brachycephaly is between 10-20% in most series of
craniosynostosis. This may occur as an isolated occurrence or part of a
more complex syndrome with facial retrusion such as Apert's or Crouzon's.
Surgical treatment consists of extended bicoronal craniectomies with reconstruction of the forehead. The supraorbital bar or brow is reshaped and advanced forward with the forehead. The reconstructed forehead and brow are rigidly fixed to the nose and lateral orbits with microplates. If there is excessive height to the skull then total calvarial remodeling is also performed, decreasing the height of the skull.
The Tennessee Craniofacial
Center, part of the Erlanger Health System, is located in Chattanooga,
Tennessee. The Center, led Larry A. Sargent, M.D., specializes in the
evaluation and treatment of patients of all ages with craniofacial deformities.
