Summary
A newly identified groove in the human skull
Area of Science:
- Anatomy
- Anthropology
- Osteology
Background:
- A groove in the sphenoid bone's greater wing was previously observed.
- Its incidence varied significantly across different populations.
Purpose of the Study:
- To investigate the prevalence of this infratemporal groove.
- To identify the anatomical structure responsible for the groove.
Main Methods:
- Examination of modern Portuguese skeletal remains.
- Dissection of twenty European cadavers.
Main Results:
- The groove was present in 85% of Portuguese crania.
- All twenty European cadavers exhibited the groove.
- Dissections confirmed the posterior deep temporal nerve forms the groove.
Conclusions:
- The infratemporal groove is a common anatomical feature.
- The posterior deep temporal nerve is consistently associated with this groove.
