ObjectiveThis study aimed to evaluate the association between facial width and length and fundamental frequency (F0) and habitual frequency.Study designProspective cross-sectional study.SubjectsA total of 50 subjects (35 females;15 males) were included in this study.MethodsLateral and posteroanterior cephalometric measurements included: facial height (N–Me); widths of the maxilla (J–J), mandible (AG–AG), and face (Zyg–Zyg); ratios J–J to AG–AG, N–Me to Zyg–Zyg, and lower face to total face heights. All subjects underwent acoustic analysis using Visi-Pitch IV. Sample was stratified according to age and gender.ResultsIn the total group (mean age: 14.19±6.49 years; range 6-35 years), a significantly moderate negative correlation existed between Zyg–Zyg, J–J, and AG–AG, and F0 and habitual pitch. Similarly, N-Me moderately correlated with habitual pitch. In males, there was a significant moderate negative correlation between Zyg–Zyg and J–J, and habitual pitch, and between J–J and F0 (−0.571;p=0.026). In females, a significant moderate correlation existed between Zyg–Zyg and AG–AG, and habitual pitch, and between AG–AG and F0 (−0.347;p=0.041). In the prepubertal group (n=25), a negative moderate correlation occurred between J–J and AG–AG, N–Me and habitual frequency, and between J–J and F0 (−0.407;p=0.043). In the postpubertal group, there was a significant moderate correlation only between AG–AG and F0 (−0.403;p=0.046).ConclusionFacial length correlates significantly with habitual frequency, and facial width correlates significantly with both F0 and habitual pitch. A larger sample of adult subjects is needed to substantiate this conclusion.
