Hypothesis
What are the distances and anatomical relations between the lower cranial nerves and important neck landmarks?
Conclusion
The anatomical position and distances of lower cranial nerves in the neck vary significantly, influenced by factors such as gender.
Supporting Evidence
- The X nerve was posterolateral to the common carotid artery in 55.6% of cases.
- The distance between the XII nerve and the carotid bifurcation was significantly greater in males.
- Anatomical variations in lower cranial nerves can lead to complications in neck surgeries.
Takeaway
This study looked at how the lower cranial nerves are positioned in the neck, finding that their locations can change a lot, especially between men and women.
Methodology
Anatomical study based on neck dissection in Thiel-embalmed cadavers.
Limitations
Small sample size and potential measurement inaccuracies.
Participant Demographics
11 adult cadavers (4 male, 7 female) with a mean age of 74.2 years.
Statistical Information
P-Value
p = .003; p = .012
Statistical Significance
