Summary
This study reveals significant epiglottis morphometric differences, with males having thicker and longer epiglottises. Omega-shaped epiglottises are longer, highlighting potential clinical relevance for airway and swallowing function.
Area of Science:
- Anatomy
- Radiology
- Medical Imaging
Background:
- Comprehensive morphometric analysis of the epiglottis is crucial for understanding airway and swallowing functions.
- Cone-beam computed tomography (CBCT) provides detailed imaging for epiglottis morphology assessment.
Purpose of the Study:
- To conduct a detailed morphometric analysis of the epiglottis using CBCT.
- To investigate epiglottis dimensions, shape variations, and their correlation with gender and age.
Main Methods:
- Retrospective analysis of 100 CBCT scans using the NewTom 5G system.
- Measurement of epiglottis thickness and angles in axial and sagittal views.
- 3D visualization for epiglottis shape identification (normal, flat, omega).
Main Results:
- Midline epiglottis thickness varied by level (4.68-6.80 mm).
- Males exhibited significantly greater epiglottis thickness and length.
- Omega-shaped epiglottises were significantly longer than flat or normal types.
- Positive correlation found between age and epiglottis thickness/angles.
Conclusions:
- Significant morphometric differences in epiglottis dimensions and shapes were identified.
- Gender (males) and shape (omega) are key factors influencing epiglottis morphology.
- Further research is needed to explore the clinical implications for airway management and swallowing.
