Killian's triangle, a weakness in the hypopharyngeal wall, is more common and larger in males. Its dimensions correlate with body measurements, potentially explaining higher Zenker's diverticulum rates in men.
Area of Science:
- Anatomy
- Human cadaver studies
Background:
- Killian's triangle is an anatomical landmark in the hypopharynx.
- Weaknesses in this area are associated with Zenker's diverticulum.
Purpose of the Study:
- To determine the prevalence and morphometric characteristics of Killian's triangle.
- To investigate the relationship between Killian's triangle features and anthropometric measurements.
Main Methods:
- Prospective examination of the hypopharyngeal wall in 47 human cadavers.
- Dissection to identify and measure Killian's triangle.
- Correlation analysis with whole body and head/neck anthropometric data.
Main Results:
- Killian's triangle was present in 60% of males and 34% of females.
- Mean triangle height was 7mm (males) vs 4mm (females); mean width was 16mm (males) vs 12mm (females).
- Triangle dimensions significantly correlated with body size and laryngeal descent.
Conclusions:
- Killian's triangle prevalence and size are greater in males.
- Morphometric characteristics correlate with anthropometric features.
- Findings may explain higher Zenker's diverticulum incidence in men and geographical variations.
