Abstract:
This study aimed to investigate the changes in tongue-palatal contact patterns in patients with mandibular lateral deviation by electropalatography (EPG) before and after sagittal split ramus osteotomy (SSRO). Ten mandibular asymmetry patients who underwent SSRO participated in the study. Tongue-palatal contact patterns for the production of /t/ and /s/ sounds were observed using EPG before surgery and 3 months after surgery, and the changes in EPG pattern were examined. The number of electrode contacts in the 2 vertical columns of the EPG plate was calculated both in the mandibular deviation side and the nondeviation side. The EPG patterns for /t/ and /s/ showed asymmetry before surgery but became normal after surgery. Before surgery, the number of electrode contacts in the 2 vertical columns in the mandibular deviation side was significantly lower than that in the nondeviation side and the normal participants during /t/ and /s/ articulation. However, the number of electrode contacts in the deviation side significantly increased after surgery. This study demonstrated that the tongue-palatal contact patterns for /t/ and /s/ articulation shifted to the direction of mandibular deviation and improved after SSRO.
