Summary: | Introduction: This study was undertaken to observe the
frequency of mastoid canals and grooves in north Karnataka
dry human skulls. 100 dry human skulls of unknown age and sex
from the department of Anatomy were selected and observed
for the present study.
Material and Methods: The mastoid regions of dry skulls were
observed for the presence of mastoid canals and grooves,
if any. A metallic wire was passed through the canal for its
confirmation and then the length was measured.
Results: The Mastoid canals were present in 53% of the total
100 skulls observed either bilaterally or unilaterally. Mastoid
grooves were present in 18% of the total skulls (100) observed.
Double mastoid canal was found in 01% of total skull studied
and both Mastoid canals & Mastoid grooves together were
present in 02% of the total skulls (100) observed.
Conclusion: The knowledge of mastoid canals and grooves
is very important for otolaryngologists and neurosurgeons.
Because they contain an arterial branch of occipital artery with
its accompanying vein which is liable to injury resulting into
severe bleeding. |
