Uncomplicated trigonocephaly. A radiographic affirmation of conservative therapy

Trigonocephaly is a relatively rare deformity of the skull characterized by triangular prominence of the bones of the forehead and orbital hypotelorism. Long-term results in a group of patients with clinical and radiographic follow-up are analyzed, the radiographic findings reviewed, and possible etiologies discussed. The etiologic relationship between premature synostosis of the metopic suture and trigonocephaly is questioned. Uncomplicated trigonocephaly is a self-limited, self-correcting deformity, and a normal cosmetic appearance develops without surgical treatment. Surgical craniectomy as treatment for uncomplicated trigonocephaly is not indicated on the basis of the authors' experience.
