  ABSTRACT: Objective(s): The aim of this study is to explore if there is a correlation between the typical voice classification and the oropharyngeal and laryngeal morphology, using video laryngeal stroboscopy and cervical posterior-anterior radiography on professional singers in Greece. Methods: 55 professional singers (28 females: 7 sopranos, 12 mezzo-sopranos, and 9 contraltos; 27 males: 8 tenors, 12 baritones and 7 basses) were recruited for this study. All participants underwent stroboscopic and cervical posterior-anterior radiographic imaging of their oral pharyngeal and laryngeal area. Additionally, the voice classification and features (e.g., height, weight) of individuals were correlated statistically. Results: Statistically significant correlations were observed between the VC of the participants with the Phonetic Area (PA) (r = −0.451, p = 0.001) and the VC with the Oral-pharyngeal Cavity (OPC) area (r = −0.402, p = 0.001) in the total sample. Specifically, in male singers, the PA and VC correlation was r = −0.319, p = 0.047, and the VC and OPC area was r = −0.328, p = 0.044. Likewise, in female singers, the PA area and VC and PA were r = −0.336, p = 0.041 and the OPC area and VC were r = −0.344, p = 0.039. The analysis confirmed no correlations between VC and height and body weight. Conclusions: The cervical posteroanterior radiography in conjunction with laryngeal stroboscopy provided new morphometric correlations of the VC of professional singers with their Oropharyngeal and Laryngeal Anatomy.
