Additional Information for General Practitioners:

Referral Guidelines:

We accept referrals from GP’s (inside our catchment area of North County Dublin) for general patients and nationally for Airway and Vestibular patients. Once a referral letter is received, it is triaged by an ENT Consultant and appointment is issued in due course.


Tonsillectomy Guideline Critieria:

  • Episodes of sore throat are disabling and prevent normal functioning
  • 7 or more well documented, clinically significant, adequately treated sore throats in the preceding year; or
  • 5 or more episodes such episodes in the preceding 2 years; or
  • 3 or more such episodes in each of the preceding 3 years

Epistaxis (Nosebleeds):

  • Topical antiseptic treatment with Naseptin cream is highly effective in reducing crusting and vestibulitis as a first line of treatment for recurrent epistaxis in an outpatient or GP setting.
  • When to refer:
    • If epistaxis is recurrent despite treatment with Naseptin cream.
    • Teenage boys with recurrent episodes of epistaxis require prompt referral to ENT to outrule a Juvenile Nasopharyngeal Angiofibroma (JNA). 

Bone Anchored Hearing Aid (BAHA) Clinic:

The Temple Street BAHA Centre specialises in helping children who are unable to wear conventional hearing aids

What is the difference between conventional hearing aids and BAHA?

  • Hearing aids send amplified sound waves through the outer and middle ears into your inner ear, also known as the cochlea.  If there are blockages along the way, sound waves cannot effectively get through. 
  • BAHA (Bone Anchored Hearing Aid) system overcomes this by sending vibrations directly through the bone in the skull straight to the inner ear, bypassing any problematic areas in between.  A sound processor is fitted to the outside of the head and this technique is known as bone conduction
