Introduction: The
knowledge of precise location of various mandibular anatomical landmarks is
mandatory to obtain the desired surgical outcome. Damage to the nerve can be
caused by perforation of the nerve canal during different surgical procedures.
Accessory mental foramen (AMF) is a relevant anatomic structure with widespread
importance as its presence may cause failure to achieve adequate level of
anesthesia using conventional nerve block technique. Aim: To assess
the inferior alveolar nerve canal position and accessory mental foramen using
CBCT. Objective: 1) To assess the linear relationship of the alveolar nerve canal
(ANC) to buccal and lingual cortex, bone crest to canal on both
sides of mandible. 2) To identify the occurrence and location of AMF as a rare
anatomical variation on both side of mandible. Materials and methods: A total
178 mandibular CBCT scans were examined for AMF and the linear relationship ANC
to buccal and lingual cortex, bone crest to canal in both side of mandible was
evaluated in cross-section. Result: Out of
the studied population, 13 AMF were detected in 12 subjects (9 Males, 4 Females). Gender
wise comparison of the linear measurement of the study population in buccal
cortex, lingual cortex, cortical width, total
width through centre of inferior alveolar nerve canal (IANC) and diameter of
inferior alveolar nerve canal (IANC)
shows no statistically significant variance (P > 0.05). Conclusion: The presence
of anatomical variations is frequently neglected. To get
rid of iatrogenic injuries during the surgical procedures, it is
important to identify these variations by presurgical imaging examination which
permits more accurate planning and contributes more
successful treatment.
