For use in the reconstruction of the ossicular chain, in conjunction
with a cortical bone graft, taken from the outer table of the skull,
in which a notch is ground to accommodate the malleus and into which
a 0.5mm blind hole is drilled to accept the columella.
The bone graft is placed adjacent to the ear drum, across the malleus
and the columella completes the connection to the footplate of the
stapes.
Note: the smallness of the device makes it easy to see the footplate
during its insertion and so minimizes the risk of fixation to the
margins of the oval window niche.
CAMPBELL ENDOLYMPHATIC T-SHUNT
This
device is intended to be placed in the sac, to relieve the symptoms
of Menière’s disease. Once in situ, it will act as a
continuous drain, allowing the endolymphatic sac fluid to be shunted
into the mastoid. The long member leaves the sac via a separate incision,
the ‘T’ bar remaining within the sac to prevent extrusion.
Being flat, like the decompressed sac, it is easier to insert than
a tubular drain and does not require insertion into the subarachnoid
space.
CAMPBELL MIDDLE EAR AERATION SHEETING
This
device is used to prevent or reduce adhesions in the middle ear following
tympanoplasty, especially those from the malleus to the promontory
and from the ear drum to the inner ear. After reconstruction of the
tympanic membrane and ossicular chain, this implant is inserted into
the mouth of the eustachian tube, to cover the promontory, and under
the handle of the malleus, to cover the middle ear, the shape allowing
it to rest around the oval window.
CAMPBELL ATTIC TO ANTRUM IMPLANT
This
implant is intended to aerate the attic and mastoid antrum, in order
to encourage the regrowth of the mucosa, following tympano-mastoid
surgery. The narrow end is placed under the head of the malleus, if
present, and back into the mastoid antrum.
