Summary
The sphenoethmoidal complex, including ethmoidal cells and sphenoid sinuses, shows rapid development in early childhood. While size differences between sexes are minimal initially, they become statistically significant by age 25, impacting infantile midface diseases.
Area of Science:
- Anatomy
- Radiology
- Pediatrics
Background:
- Accurate knowledge of paranasal sinus development is crucial for understanding infantile midface diseases.
- Understanding age- and sex-related sinus development aids in minimizing risks during therapeutic interventions.
Purpose of the Study:
- To evaluate the sex-related size and presence of paranasal sinuses from birth to age 25.
- To focus on the ethmoidal cells and sphenoidal sinuses, key components of the sphenoethmoidal complex.
Main Methods:
- Analysis of over 5600 axial computed tomographic (CT) images.
- Evaluation of sinus width, length, and evidence in individuals from birth to 25 years old.
Main Results:
- The sphenoethmoidal complex develops rapidly in early childhood, with ethmoidal cells 94% developed in newborns.
- Statistically significant size differences between sexes emerge by age 25, particularly in sphenoid sinus length and ethmoidal cell width.
- Substantial variability was observed in sphenoidal sinus dimensions, with intersphenoidal septum data provided.
Conclusions:
- The ethmoidal cells and sphenoidal sinuses are critical in early infantile paranasal sinus diseases.
- Findings align with existing anatomical and radiological studies, providing detailed size data across different ages and sexes.
- This study offers precise measurements of paranasal sinus development, essential for clinical assessment and research.
