Mastoid Surgery Animation (Basic to Radical Mastoidectomy)


Mastoid surgery is performed by removing the
hollow bone behind the ear. The procedure begins by making an incision
and retracting the ear forward to expose the mastoid bone surface. The honeycomb partitions of the mastoid bone
are then drilled away down to where it connects to the middle ear. There are important structures that are preserved
during the process including: Semicircular canals which are responsible
for inner ear balance. The bone that separates the brain from the
middle ear and mastoid The sigmoid sinus which is a large blood vessel
which connects to the jugular vein in the neck. Chorda tympani nerve which supplies sense
of taste to the tongue. And finally the facial nerve which is responsible
for facial movements. This would be the extent of a basic simple
mastoidectomy. Occasionally, the facial recess may be dissected
out as shown here. An even more aggressive mastoid surgery may
be required should a type of ear cyst called a cholesteatoma be the reason that the surgery
is performed In rare situations the wall separating the
ear canal and mastoid cavity is removed to eradicate ear disease. The eardrum and middle ear bones may even
be removed.
