The aim of this study is to explore if there is correlation between the typical voice classification and oropharyngeal anatomy, using cervical posterior-anterior radiography on professional singers in Epirus, Greece. Methods: 70 professional singers, 35 men and 35 women, were recruited for this study. All participants underwent a cervical posterior-anterior radiographic imaging of their oral pharyngeal and laryngeal area. Results: A statistically significant difference of mean distance was observed for the CI-MHP area (p=0,004), the MHP- SCV area (F=2,62, p=0,032), as well as SCV-AI area (F=11,82, p=0,000). For the average length measured in mm of the phonetic area PA, statistically significant differences were computed among all the singers in the group (F [5] = 5.368, p = 0.001), as well as the OPC area (F = 6,48, p = 0,000). Conclusions: The cervical posteroanterior radiography provided new correlations of the voice category of professional singers with their Oropharyngeal and Laryngeal Anatomy.
