Summary
Maxillary sinus volume increases until age 20, then decreases. Age-related changes in sinus volume correlate with facial skeletal size and body physique, aiding abnormality identification.
Area of Science:
- Anatomy
- Radiology
- Anthropology
Background:
- Understanding normal maxillary sinus volume changes with age is crucial for diagnosing sinus abnormalities.
- Maxillary sinus volume is influenced by various anatomical and physiological factors.
Purpose of the Study:
- To measure normal maxillary sinus volume in relation to age, dentition, skeletal size, and body metrics.
- To establish normative data for maxillary sinus volume across different age groups.
Main Methods:
- Analysis of axial CT scans from 115 cases to determine maxillary sinus volume.
- Correlation analysis with patient age, presence of teeth, midfacial skeletal dimensions, and body mass.
Main Results:
- Maxillary sinus volume ranged from 4.56-35.21 cm³ (mean 14.71 cm³) in adults over 20.
- Volume increased until age 20, then decreased, with no significant sex differences.
- Adult volume correlated with interzygomatic buttress distance, and in females with zygomatic-occipital distance; in males, with height and weight.
Conclusions:
- Maxillary sinus volume exhibits age-related changes potentially linked to skeletal growth and physique.
- Normative data on maxillary sinus volume can aid in the detection of pathological conditions.
