    This study establishes normal computed tomography (CT) values for the adult neck, providing crucial reference data for prevertebral soft tissue and upper airway dimensions. These findings aid in diagnosing cervical abnormalities and assessing laryngeal function using CT scans.

    Area of Science:

    • Radiology
    • Anatomy
    • Medical Imaging

    Background:

    • Accurate reference values for cervical soft tissues and airway dimensions are essential for interpreting medical imaging.
    • Previous studies may lack comprehensive data across diverse adult age groups for detailed cervical region analysis.
    • Computed tomography (CT) offers detailed visualization of the neck's anatomy, crucial for diagnostic accuracy.

    Purpose of the Study:

    • To determine radiodiagnostically relevant normal values and variations for key measurements in the healthy adult cervical region.
    • To establish standard deviations and arithmetical averages for cervical measurements using CT.
    • To provide data for assessing laryngeal function through CT-based anatomical and movement analysis.

    Main Methods:

    • Evaluation of computer tomograms from 60 healthy adult men and women (aged 20-83 years).

  • Measurement of prevertebral soft tissue sagittal diameter and upper respiratory tract lumina at defined cervical levels.
  • Assessment of aryepiglottic folds, thyroid gland dimensions, cervical vessel calibre, and laryngeal/hypopharyngeal distances and vocal cord movement during respiration and phonation.

    • Main Results:

    • Established normal values and standard deviations for sagittal diameters of prevertebral soft tissue and upper airway lumina.
    • Defined measurements for thyroid gland size, aryepiglottic folds, great cervical vessels, and laryngeal/hypopharyngeal anatomy.
    • Quantified vocal cord movement during normal respiration and phonation using CT.

    Conclusions:

    • The study provides a comprehensive dataset of normal CT values for the adult cervical region.
    • These reference values are vital for accurate diagnosis of cervical pathologies and assessment of laryngeal function.
    • CT-based measurements offer valuable insights into the anatomy and functional dynamics of the larynx and hypopharynx.
