ABSTRACT

Background: The hypoglossal canal is a bony canal in the occipital bone of the skull. The hypoglossal nerve is the twelth cranial nerve passes through the hypoglossal canal (HC) that supplies motor innervations to the tongue.

Materials and Methods: A total of 50 adult dry skulls were examined from the department of anatomy, Stanley Medical College, Chennai, Tamilnadu.

Results: Out of 50 skulls studied, double hypoglossal canal was seen in 10 (20%) skulls, in which 7 (14%) specimens had unilateral while 3 (6%) specimens had bilateral double hypoglossal canal. Double hypoglossal canal was more common in right side. The mean length of hypoglossal canal on the right and left were 12.45mm and 12.51mm. The mean diameter of intra and extracranial end of hypoglossal canal were 7.48mm and 7.59mm respectively.

Conclusion: Hence, the knowledge about its morphometric dimensions of hypoglossal canal is very important for neurosurgeons & radiologists.

Key words: Hypoglossal canal, Skull, hypoglossal nerve.
