It appears that hearing loss can be a complication, although a rare
one, after cardiac surgery in which a cardiopulmonary bypass pump is
used, and it can also be a rare complication following general
anesthesia. It is also a complication in situations where leakage of
cerebrospinal fluid occurs, for example following procedures that
involve lumbar puncture.

“Hearing loss after cardiopulmonary bypass surgery” by Walsted A,
Andreassen UK, Berthelsen PG, Olesen A. of Department of Audiology,
Gentofte University Hospital, Hellerup, Denmark.
The authors state: “Hearing loss is a rare complication following
cardiac surgery with extracorporal circulation or other non-otologic
surgery under general anesthesia” They describe four cases of
profound hearing loss after coronary artery bypass or cardiac valve
surgery in which a cardiopulmonary bypass pump was used. Three of the
patients had hearing loss as soon as they recovered from anesthesia,
while the fourth experienced a loss in hearing over the first week
after the surgery.

“Hearing loss after general anesthesia for cecectomy and small bowel
resection” by FA Velazquez (no address supplied)
“Acute hearing deficit following nonotologic surgery and general
anesthesia is a rare phenomenon. Hearing loss following anesthesia has
more commonly been associated with spinal anesthesia or following
cardiopulmonary bypass surgical procedures.” However, the author goes
on to describe a patient who developed hearing loss after bowel
surgery.

Sudden sensorineural hearing loss: operative complication in
non-otologic surgery.
by Millen SJ, Toohill RJ, Lehman RH. (no address given)
“Sudden sensorineural hearing loss is a well recognized phenomenon in
otologic practice with both viral and vascular etiologies being
supported. However, sudden hearing loss as a complication of
non-otologic surgical procedure is a seldom reported and rare
phenomenon. Five cases of unilateral sudden sensorineural hearing loss
which are time related and probably causally related to non-otologic
surgery are presented. Two cases underwent open heart surgery and
support previous reports of hearing loss secondary to cardiopulmonary
bypass procedures.”

the English literature revealed only 15 cases of SNHL after general
anesthesia for nonotologic surgery… … Sudden SNHL after

Here are a couple of studies that are suggesting a link between the
physiology and tissue structure of the ear and the cardiac system,
although they both deal with very specific conditions, one of which is
of genetic origin, rather than heart disease in general:
5. One example of an article on the association between hearing loss
and lumbar puncture:
Journal of Perianesthesia Nursing (April 2002, Vol 17 (no.2) p. 89-98)
“Sensorineural hearing loss after select procedures” by SM Irvin of
Ambulatory Surgery Unit at the Veterans Affairs Medical Center,
Memphis, TN, states that “Cardiac surgical procedures are most
commonly associated with hearing loss owing to the use of the
cardiopulmonary bypass pump”. With respect to non-cardiac procedures,
there is an association between leakage of cerebrospinal fluid and
subsequent hearing loss, making hearing loss a possible consequence
of, for example, lumbar puncture.

8 Dilated Cardiomyopathy and Sensorineural Hearing Loss A Heritable
Syndrome That Maps to 6q23–24 by Jost Schönberger, MD (Harvard) and
others
The authors conclude: “A syndrome of juvenile-onset sensorineural
hearing loss and adult-onset dilated cardiomyopathy is caused by a
mutation at 6q23 to 24 (locus designated CMD1J). Recognition of this
cardioauditory disorder allows for the identification of young adults
at risk for serious heart disease, thereby enabling early
intervention. Definition of the molecular cause of this syndrome may
provide new information about important cell physiology common to both
the ear and heart.”

Sensorineural hearing loss in conjunction with aortic insufficiency in
systemic lupus erythematosus.
Peeva E, Barland P.
Department of Medicine, Albert Einstein College of Medicine, Bronx,
NY, USA.
“We are describing two patients with well-established SLE who
developed bilateral hearing loss and aortic insufficiency, associated
with serological evidence of active lupus… … Our observations suggest
that the aortic valve and the inner ear may share some antigenic
crossreactivity”
(My reading of this is that if tissue damage occurs at one of these
two places, and this stimulates the formation of autoantibodies to
tissue components – a rare but possible occurrence, these
autoantibodies might also cause damage in the other location)
