The author studied 100 sides of calvaria which was collected to the Department of
Anatomy of Yonsei University, College of Medicine, concerning to anatomical
structure of the passage of middle meningeal artery, the size of foramen spinosum,
the size of foramen ovale, the relationship of anatomical location of the foramen
spinosum and foramen ovale, the distance between foramen spinosum and foramen
ovale, the distance of common trunk of the middle meningeal artery, the distance
between the articular tubercle and foramen spinosum of the temporal bone, the
presence of bony canal of the anterior branch of middle meningeal artery. And on

ovale was as followings.
The 87 cases (87.9%) of foramen spinosum was located posterior laterally, 6 cases
(6.1%) was located laterally, 3 cases (3%) was located posteriorly.
And the 3 cases (3%), the foramen spinosum was continued to the foramen ovale.
No case was located medially.
5. The distance between foramen spinosum and foramen ovale was as followings.

(7.7%) was 4mm to 5mm, and the 4 cases (4.4%) was above 5mm.
6. The distance of common trunk of the middle meningeal artery was as followings.
The 11 cases (11.2%) was less than 5mm, the 20 cases(20.4%) was 6mm to 10mm, the
9 cases (9.2%) was 11mm to 15mm, the 5 cases (5.1%) was 16mm to 20mm, the 9 cases
(9.2%) was 21mm to 25mm, the 17 cases (17.3%) was 26mm to 30mm, the 17 cases
(17.3%) was 31mm to 35mm, the 9 cases (9.2%) was 36mm to 40mm, and 1 case (1%) was
41mm to 45mm.
7. The distance f between the articular tubercle and foramen spinosum of the
temporal bone was followings.

cases (50.5%) was 31mm to 35mm, the 6 cases (6.2%) was 36mm to 40mm, and the 2
cases (2.1%) was 41mm to 45mm.
8. The presence of bony canal of the anterior branch of middle meningeal artery
was as followings.
The 33 cases (63.5%) was absent on both side, the 9 cases (17.3%) was present on
both side, and the 10 cases (19.2%) was present unilaterally.
9. The type of middle meningeal artery was as followings.
The 16 cases (32.0%) was type 1. the 9 cases (18.0%) was type 2, the 11 cases
(22%) was type 3, and the 14 cases (28.0%) was type 4.
