Trigonocephaly: some clinical and surgical features.

Trigonocephaly is a partial form of craniostenosis or rather craniofaciostenosis in which the esthetic damage is severe and early and in which the functional damage (mental retardation, strabismus) may also be severe. The former can be corrected and the latter prevented by early and appropriate surgery. A new surgical procedure for correcting uncomplicated trigonocephaly permits normal development of the skull and orbits and normal psychomotor development.
