| description | Background: The internal carotid artery supplies the anterior
part of the brain, the eye and its appendages and sends
branches to the forehead and nose.Carotid canal is a curved
channel in the petrous temporal bone through which internal
carotid artery enters the skull.
Aim: In the present study 20 skulls of unknown sex were
considered. The morphometric study of carotid canal was
studied by direct bone method and by silicone cast method. The
present study aimed to show the differences of measurements
by two methods and the silicon cast method is of its kind to
measure the length of the carotid canal.
Materials and Methods: Carotid canal were measured at three
different levels by both methods. Length of carotid canal to
bend, diameter at the bend, length from the bend to foramen
lacerum. The data was analysed for all the measurements of
two methods and comparison of mean and SD at three different
levels was done.Significant difference between two methods at
three different levels was observed. Independent sample t-test
was applied for total length of carotid canal.
Results: By observation there is a mean significant difference
between two methods in the measurements of carotid canal
from lower opening till the angulation on left side of the skull.
The study showed that there is a bilateral significant difference
in measurements of diameter between two methods. There was
no significant difference observed in total length of the canal in
both left and right sides.
Conclusion: Morphometrical details of the canal are of great
significance to neurosurgeons and otologists. Silicon cast
method was cost effective and much easier method to study
the length and measurements of carotid canal as it exactly
depicts the curvature of carotid canal. |
