Relations between body mass index, laryngeal fat pads, and laryngeal airway configuration in adult men population.

Background: The impact of body mass index (BMI) on pharyngeal fat pads has been well studied, yet no study has assessed its associations on laryngeal morphology.

Objectives: To study the associations of BMI differences on laryngeal morphology in adult males using computed tomography angiography (CTA) scans.

Methods: All adult male patients who underwent head and neck CTAs between 2011 and 2018 were initially included and categorized according to their BMI: (1) BMI < 20; (2) 20 ≤ BMI < 25; (3) 25 ≤ BMI < 30; (4) 30 ≤ BMI < 35; and (5) BMI ≥ 35.
