Anatomy of the larynx and pharynx: effects of age, gender and height revealed by multidetector computed tomography

Summary Although oropharyngeal and laryngeal structures are essential for swallowing, the three‐dimensional (3D) anatomy is not well understood, due in part to limitations of available measuring techniques. This study uses 3D images acquired by 320‐row area detector computed tomography (‘320‐ADCT’),...

Zusammenfassung:Summary Although oropharyngeal and laryngeal structures are essential for swallowing, the three‐dimensional (3D) anatomy is not well understood, due in part to limitations of available measuring techniques. This study uses 3D images acquired by 320‐row area detector computed tomography (‘320‐ADCT’), to measure the pharynx and larynx and to investigate the effects of age, gender and height. Fifty‐four healthy volunteers (30 male, 24 female, 23–77 years) underwent one single‐phase volume scan (0·35 s) with 320‐ADCT during resting tidal breathing. Six measurements of the pharynx and two of larynx were performed. Bivariate statistical methods were used to analyse the effects of gender, age and height on these measurements. Length and volume were significantly larger for men than for women for every measurement (P
