Three-dimensional computed tomographic analysis of frontal sinus in Asians

Area of Science:

• Anatomy
• Radiology
• Pediatrics

Background:

• Limited research exists on frontal sinus development in children using 3D CT.
• Understanding normal frontal sinus development is crucial for clinical applications.

Purpose of the Study:

• To evaluate the normal development of the frontal sinus in Asian children.
• To analyze frontal sinus dimensions (height, length, width, volume) in Korean adults.

Main Methods:

• Retrospective review of 3D facial bone CT scans from 352 patients under 23 years old.
• Age-based evaluation of frontal sinus occurrence and pneumatization.
• Measurement of frontal sinus dimensions and volume using computer software.

Main Results:

• Frontal sinus pneumatization was observed in children over 4 years old.
• Continuous growth in length, height, width, and volume occurred until age 20, peaking during puberty.
• High correlation (r=0.8) found between frontal sinus width/volume and height/length.
• Mean adult dimensions: height 27.2±7.0 mm, width 52.5±17.1 mm, depth 22.0±6.3 mm, volume 8.39±3.78 cm³.

Conclusions:

• Frontal sinus development is a continuous process throughout childhood and adolescence.
• This study offers valuable data for understanding normal frontal sinus growth in children.
• Findings can aid future research and surgical planning for frontal sinus procedures.
