This study used 125 lateral cephalometr ic radiographs (40 males and 85 females) as samples which taken from a server at the Dental Radiology Installation, RSGM FKG Trisakti University . Results: The result showed that the smallest mean width of the anteroposterior frontal sinuses in males is at 7 years (5.4 mm) and the largest size is at 19 years (9.76 mm). Whereas the smallest mean width of anteroposterior frontal sinuses in females is at the age of 7 years (5.4 mm) and the largest size is at the age of 20 years (9.25 mm). The average width of anteroposterior frontal sinuses is 6.6 mm in males and 5.58 mm in females. Conclusion: Males have an average width of anteroposterior frontal sinuses that is larger than females and there are some decrease in size in some age groups. Variations in size can occur due to genetic and environmental factors.   UR - http://jurnal.pdgi.or.id/index.php/jrdi/article/view/616
