Abstract

Purpose: Scoliosis is a three-dimensional spinal deformity that induces asymmetries in the body. Existing literature primarily focuses on asymmetries caused by scoliosis, particularly in the shoulders, waistline, breasts, and pelvis. This study aimed to compare differences in facial, neck, and shoulder symmetry profiles of adolescents with idiopathic scoliosis and healthy peers through two-dimensional photographic methods.
Methods: Thirty-one adolescents diagnosed with Adolescent idiopathic scoliosis (AIS) and 31 healthy controls participated in the study. Facial, neck and shoulder asymmetry were evaluated in 2D photogrammetry. Active mandibular movements were measured with a ruler, while neck mobility was assessed using a standard flexible tape. Axial cervical rotation was measured with a scoliometer.
Results: The findings revealed that participants with AIS exhibited greater asymmetry in eye, midface, and mouth regions compared to healthy peers. Additionally, individuals with scoliosis displayed significant asymmetry in the right to left trapezium angle ratio, as well as noticeable differences in shoulder and axillary heights.
Discussion: The results suggest that scoliosis-related asymmetries are not confined to the trunk but also affect the head, neck, and shoulder regions.
