Lingual foramen around genial tubercle in adult Indian human mandibles
DR.NIMJE DIPTI A, DR.YADAV NISHA RB
Abstract:
INTRODUCTION: The mandible has many unnamed accessory
foramina present on the lingual surface, on or near the genial tubercles.
The lingual foramen is situated in the midline and above the superior
genial tubercles. Many Anatomical textbooks have failed to describe this
foramen
MATERIALS AND METHODS: 120 dried human adult mandibles of
unknown sex were collected from department of Anatomy and examined
for the presence of a foramen in the midline of the lingual surface in
relation with the genial tubercles
RESULT: A constant midline foramen situated above the superior genial
tubercles was found to be present in 84 mandibles i.e. 70% of dried
mandibles. Foramen situated below the inferior genial tubercles was seen
in 5 mandibles i.e. 4.16% and foramen on the side of genial tubercles was
seen in 3 mandibles i.e. 2.5%. 7 mandibles have shown more than one
type of foramen around the genial tubercle i.e.5.83%
CONCLUSION: The high incidence of this mandibular lingual foramen
(70%) increase the attention over the ligual surface of the mandible due to
its neurovascular contents.
