title: Structural and Anatomic Laryngeal Measurements in Geriatric Population Using MRI.
abstract: OBJECTIVE
  The study aims to evaluate the changes in volume and dimensions of the thyroarytenoid (TA) muscle in the elderly using magnetic resonance imaging (MRI).
  
  
  METHODS
  This is a retrospective study.
  
  
  METHODS
  The neck MRIs of 40 adult patients aged less than 65 years old and 40 patients aged 65 years old and above were compared. Demographic data included age and gender. The length, width, and height of the TA muscle as well as its volume were measured on each side, right and left, in both groups.
  
  
  RESULTS
  The differences in the mean length, width, and height of TA muscle were not statistically significant between the two groups on either right or left side. Similarly, there was no statistically significant difference in the mean volume of the TA muscles between the two groups on either side as well. The mean volume of the right and left TA muscles in those aged less than 65 years was 0.65 ± 0.26 mL and 0.69 ± 0.30 mL, respectively. The mean volume of the right and left TA muscles in the elderly group was 0.72 ± 0.31 mL and 0.72 ± 0.32 mL, respectively.
  
  
  CONCLUSIONS
  Using MRI, there are no dimensional or volumetric changes in TA muscles with aging.
