# Determination of pharyngeal airway space volumes and their correlation with gender and age: A retrospective CBCT study

## TL;DR

This study analyzed CBCT scans to measure airway volumes and found that gender and age significantly affect airway size.

## Contribution

The study provides new insights into how gender and age correlate with upper airway volume measurements using CBCT.

## Key findings

- 45% of patients had reduced airway volume, 21.7% had increased volume, and 33.3% had normal volumes.
- Male patients had significantly higher nasopharyngeal and total upper airway volumes.
- Oropharyngeal volume decreased notably with age.

## Abstract

An analysis of full skull cone beam computed tomography (CBCT) scans of 180 patients to measure the upper airway volumes and analyze
correlations with age and gender is of interest. Results showed that 45% of patients had reduced airway volume, 21.7% had increased
volume and 33.3% had normal volumes. Male patients had significantly higher volumes of the nasopharyngeal (NPV) and total upper airway
volume (TV) values, with a notable age-related decrease in oropharyngeal (OPV). The study highlights gender and age as significant
factors influencing airway volumes.
