Paediatric Service- Referrals

assessed at Community based clinics across
Glasgow
• We may see many children with conductive HL,
where surgical intervention may be more
appropriate to amplification

Physician and/or Ear, Nose and Throat
Consultant are available
• Referral to Crosshouse Hospital for assessment
regarding Cochlear Implant is also an option
Adult Service- Referrals
• ENT consultants vet referrals for new
assessments (Senior Audiologists pull any
obvious referrals marked for HAC)
• Patients who have or have had a NHS hearing
aid can self refer to have a reassessment done.
They do not need a GP ref.
• On 3 sites (GGH,GRI & VI) audiology will see
over 12’s, under 60’s with no significant ENT
history
• DV’s available to patients who are housebound

Hearing Loss- Categorization
Types of Aids
• We supply digital hearing aids to anyone
who is appropriate
• We supply BTE aids as standard and ITE
aids only to patients with anatomical
complications or to some children
• We also offer referral to the cochlear
implant centre at Crosshouse Hospital via
ENT as well as BAHA (Bone Anchored
Hearing Aid) in special circumstances
BTE Aid
• Standard issue digital
hearing aid
• Some come with volume
controls
• Some have a button to
change the programme to
adapt to background
noise or to use a telecoil
loop
• Battery powered – it will
give a beep when battery
is low
Open Fit BTE
• Smaller tube without a
custom mould so a
smaller aid
• Used for milder hearing
losses only
• Works automatically so
no additional controls
• Battery powered - it will
give a beep when battery
is low
Moulds
• Earmoulds connect the
hearing aid to the
patient’s ear via a piece
of tubing
• Custom made from an
impression of the
patient’s ear
• Can be made from hard
acrylic and a softer
silicone depending on the
hearing loss
• If the aid is whistling
then the mould is not
fitting the ear correctly
and must be altered or
replaced
Hearing Aid Care
• Keep away from water!!!
• And pets!!! (Dogs seem to like chewing hearing aids!!!)
• The tubing needs to be changed and the aids checked
every 6 months via the repair department.
• The mould can be cleaned using a damp cloth or
alcowipe every day
• Wax build up in the tubing can be removed with a wax
tool.
• If the aid is whistling then check the mould or
patient’s ear for wax. (MORE ON THIS LATER!)
Batteries & Repairs
• The five Adult sites run repair services to
replace/maintain NHS hearing aids, Yorkhill
have a separate appointments system outlined
at 1st Issue
• This is a self referral system – patients do not
need to see GP
• Glasgow Royal Infirmary, Victoria (New) &
Southern General- APPOINTMENT SERVICE
• Gartnavel General &
Stobhill (New)- DROP IN SERVICE
• Some large health centres have a supply of
batteries for NHS users only, and are free
Wax Management
• Audiology provide no service in wax removal.
• Please check patients for impacted wax before
referral as this limits the tests we can carry out
• If referring to hospital for wax removal in difficult
cases (e.g. perforations) this must be sent to
ENT (nurse practitioner) not Audiology
• Before wax removal almond / olive oil to be used
for min 5 days (2-3 drops – warm)
AND FINALLY!!!
“Whistling” Hearing Aids- WHY??!
•
•
Whistling is simply FEEDBACK, the
sound of the aid amplifying its own
output
There are 4 main causes:
1.
2.
3.
4.
INCORRECT INSERTION OF EARMOULD
INFECTION OR DISCHARGE IN EAR
IMPACTED WAX IN EAR CANAL
AID TURNED UP TOO HIGH
