Summary
Objective
The purpose of this study was to determine the effects of chant training both on the
morphologic structure of the lateral thyrohyoid ligament (LTL) and on the acoustic
characteristics of the voice.
Methods
Three groups of people participated in the study. Group I was new to chant training,
group II had completed or was still continuing chant training, and group III, the
control group, did not have any chant training. For all participants, laryngeal cervical
magnetic resonance imaging was performed to measure the right and the left LTLs. Additionally,
vocal acoustic analyses were performed and compared with the anatomic morphometric
measurements. Appropriate statistical assessments were performed to evaluate the measurements.
Results
The length of the LTL was greater in men, and this finding supports the gender-specific
differences in laryngeal structures. Anatomic differences between groups showed that
8 months of training was not sufficient to trigger morphologic changes. The left and
right LTLs were asymmetric, but this finding was not statistically significant.
Conclusions
Analyses revealed that vocal training causes morphologic changes in anatomic structures,
which affect vocal quality.
