Hearing Loss Helicobacter Pylori 665
differential diagnosis
■Audiologic evaluation should establish CHL, SNHL, or mixed hearing
loss when both are present.
■CHL: external auditory canal atresia, microtia, cerumen impaction,
tympanic membrane perforation, ossicular discontinuity, otoscle-
rosis, otitis media, trauma
■SNHL: cochlear hearing loss, vestibular schwannoma, trauma, mul-
tiple sclerosis, aging, ototoxicity
management
■Amplification with hearing aids for SNHL and CHL
■Cochlear implantation when HA are inadequate
■Ventilation tube for AOM or SOM
■Stapedectomy for otosclerosis will successfully restore hearing in
95%.
■Surgery or radiation therapy for tumors of the cerebellopontine angle
(eg vestibular schwannoma)
Side Effects
■Hearing aids, while making things louder, may not help with clarity
■Surgical risks are present with cochlear implantation, placement of
ventilation tubes or resection of cerebellopontine angle tumors
specific therapy
n/a
follow-up
■Audiological evaluation every 2 to 3 years once hearing loss has been
identified
■Hearing aid checks as necessary
complications and prognosis
■CHL: medical or surgical intervention usually corrects the underly-
ing problem or provides excellent rehabilitation
■SNHL: Hearing loss usually progresses at a variable rate. Hearing aids
may provide adequate rehabilitation.
