title: The zygomatic arch and its possible influence on craniofacial growth and development.
abstract: This study was designed to investigate the role of the zygomatic arch and craniofacial growth along the anteroposterior axis. One may conclude that: 1. Surgical intervention on the zygomatic arch results in a generalized inhibition of regional zygomatic arch growth. 2. When only one zygomatic arch is sectioned, the posterior root of the sectioned side appears to be displaced posteriorly. This is a possible result of the normal growth process proceeding without the restraints of an intact zygomatic arch. 3. A decrease in anteroposterior dimension occurs in the posterior zone as a result of surgical intervention. 4. Further studies to determine the influence of the zygomatic arch on transverse maxillary growth must be completed before any clear or complete concepts of its role in craniofacial growth and development may be more fully elucidated.
