OBJECTIVE: . The aim of this study was to evaluate the position and dimensions of the genial tubercle in a Taiwanese sample.
STUDY DESIGN: Cone-beam computerized tomography (CT) records of 90 adult patients with class I or class II skeletal type were used to evaluate the position and dimensions of the genial tubercle and dimensions of the anterior mandible. Subjects were grouped by sex and skeletal type.
RESULTS: In all groups, the genial tubercle height was close to the genial tubercle width. The distance from the inferior border of the genial tubercle to the inferior border of the mandible was greater in class II male patients than in class I female patients (P < .05). The anterior mandible in class I male patients was thicker than in class II female patients (P < .05).
CONCLUSIONS: The variable position and dimensions of this structure among patients suggest the need for cone-beam CT before attempting genioglossus advancement to treat obstructive sleep apnea.
