Long face syndrome, also referred to as skeletal open bite,[1] is a relatively common condition characterised by excessive vertical facial development.
"[5] Luc P. M. Tourne, a Fellow in the Department of TMJ and Craniofacial Pain at the University of Minnesota School of Dentistry, noted: "There is a clinically recognizable facial morphology, the long face syndrome, which has been incompletely described in the literature," However, her study of 31 adults with this syndrome, which included "analysis of esthetics, skeletal morphology, and occlusion" confirmed "this basic dentofacial deformity" has associations " with excessive vertical growth of the maxilla."
[A][7] The treatment for young patients troubled by long face syndrome is to halt and control descent of the lower jaw and to prevent the eruption of posterior teeth.
While increased anterior "total and lower face height" in many ages, combined with vertical maxillary excess in adults has been observed, the causes are controversial.
[12] Anecdotally, it was said to be a genetic condition, which could only be corrected with "massive amounts" of debilitating, frequent and long dental and facial reconstructive surgery.
