Summary
Frontal sinus morphometry differs significantly between sexes, with males exhibiting larger measurements. Age did not show a significant association with frontal sinus size in this Sri Lankan population study.
Area of Science:
- Forensic Anthropology
- Radiology
- Anatomy
Background:
- Frontal sinus morphometry varies globally due to genetic and environmental factors.
- Previous studies highlight the need for population-specific data.
Purpose of the Study:
- To conduct a morphometric analysis of frontal sinuses using non-contrast computed tomography (NCCT) skull imaging.
- To assess the association between frontal sinus dimensions, age, and sex in a Sri Lankan population.
Main Methods:
- Retrospective analysis of 300 NCCT skull images from Teaching Hospital Peradeniya.
- Measurement of frontal sinus parameters (length, height, width) using specialized software.
- Statistical analysis using t-test and binary logistic regression.
Main Results:
- Left frontal sinus dimensions were significantly larger than right sinus dimensions.
- Male frontal sinus parameters were significantly larger than female parameters.
- No significant association was found between frontal sinus size and age.
Conclusions:
- NCCT-based frontal sinus morphometry aids in sex differentiation for medico-legal cases.
- Population-specific mean sinus values are valuable for ethnic differentiation.
