Background: Facial asymmetry is a common and natural phenomenon, with most people exhibiting some degree of facial asymmetry. While subtle facial asymmetry is generally unnoticeable, significant asymmetry can lead to both esthetic concerns and functional impairments. Identifying and quantifying this asymmetry is crucial for diagnosis, as well as for treatment planning in orthognathic surgery.
Objectives: This study aims to evaluate and compare methods for analyzing facial asymmetry based on cone-beam computed tomography (CBCT) imaging, with a focus on their clinical applicability and accuracy.
Methods: A systematic literature review was conducted to assess how CBCT imaging is used in the evaluation of facial asymmetry. All processing steps in the assessment are reviewed and summarized. These techniques were compared based on criteria such as precision, consistency, and practicality.
Discussion: The assessment of facial asymmetry is complex and requires careful consideration of the tools and methods used. The use of the midsagittal plane as a reference in these assessments is very common and particularly noteworthy, as it oUers a standardized approach to measuring asymmetry. However, the choice of technique may vary depending on the clinical scenario and the specific needs of the patient
