Objective: Mandibular foramen (MF) is located on
the internal surface of the ramus through which
blood vessels and nerves pass. Determination of
the anatomic position of the MF is very important
in inferior alveolar nerve block anesthesia (IANBA),
ramus osteotomy and surgical procedures of the
posterior angle of mandibular ramus. The aim of this
study was to determine anatomic position of the MF
using anatomic landmarks on the three dimensional
CBCT images. Material and Methods: A total of
103 CBCT images was evaluated. The NNT Viewer
software program was used to measure the distances
between the lines tangent on the MF periphery and
the anterior border of the ramus, the posterior border
of the ramus, the inferior border of the mandible,
and the coronoid notch in mm by to age and gender.
Results: The results showed a slight difference in
anatomic dimensions between the right and left
sides, with no significant differences. The anatomic
dimensions of the MF on both sides were a little bigger
in males than in females. There were no significant
differences in the anatomic dimensions of superiorinferior
and anterior-posterior dimensions of the left
and right sides in different age groups. Conclusion:
No significant changes occur in the position of the MF
with age. The anatomic differences between males
and females should be taken into account during
IANBA procedures. Males have bigger jaws than
females; therefore, there is a longer distance between
the MF and the anatomic landmarks evaluated.
