Objectives: To determine the relationship in detail
between the tympanic and the labyrinthine segments
of the facial nerve and the relationship between the
bony structures and the neighboring nerve.
Material and Methods: Measurement of the length
of the segment of the facial nerve within the internal
auditory canal and the lengths of the labyrinthine and
tympanic segments were made on fourteen temporals
bones collected from eight fresh cadavers.
Results: The minimum distance between the point
where the facial nerve leaves the internal auditory
canal and the tympanic segment was measured
4.71±0.54 mm. The angle between the labyrinthine
and the tympanic segments at the geniculate ganglion
was measured 73°85´±10°.89´. The angle
between the labyrinthine and the superior vestibular
nerve are measured 34°35´±5°51´.
Conclusion: We believe that the results of our measurements
will help the surgeons to minimize the complications
who works in this particular anatomic area.
