Facial symmetry plays a crucial role in individual appearance, and asymmetry in the mandible can lead to uneven growth due to specific bone formation processes.
This study aimed to analyze the effects of masseter muscle resection on craniofacial growth by reviewing relevant research published until October 2022, using established evaluation methods for bias and eligibility.
The findings from seven studies indicate that removing the masseter muscle significantly affects jaw development in rats, impacting the growth direction and shape of the mandible.
