The suture dominance theory of craniofacial growth, proposed by Sicher, emphasizes that the growth of craniofacial bones is primarily directed and controlled by the sutures. According to this theory, the sutures act as growth centers where new bone is deposited, allowing for the expansion and shaping of the craniofacial skeleton. This concept is crucial in surgical planning, especially in pediatric craniofacial surgery, as manipulating or preserving sutures can influence postoperative growth and outcomes. Sicher’s work laid the foundation for understanding the role of sutures beyond mere joints, highlighting their active contribution to bone development and remodeling.
