Welcome to the Department of Audiovestibular Medicine (AvM) (Previously known as Audiological Medicine)

This is a tertiary service providing individual care to adults and children with hearing, balance and related problems. The department covers the population from a wide catchment area including Surrey, Hampshire, Sussex and Middlesex.  AvM is a medical specialty and we work alongside Ear, Nose & Throat and Audiology.  We also work closely with our colleagues in other clinical specialties in Cardiology, Clinical Genetics, Elderly care Medicine, Immunology, Neurology, Ophthalmology, Oncology, Paediatrics and Rheumatology. We regularly liaise with Services such as Education, Speech and Language, Physiotherapy, and Cochlear Implant Centres.

More about the services we offer

Vestibular (Dizzy) Clinic:
This is a comprehensive specialist balance service which covers the diagnosis and management of a variety of dizziness / vertigo and longstanding balance disorders due to:

Benign Paroxysmal Positional Vertigo (BPPV)
Vestibular Migraine
Vestibular neuritis or labyrinthitis
Meniere’s (disease) syndrome
Central vestibular disorders (e.g. stroke) and
Any balance problems previously unexplained

Specialist (Medical) Tinnitus Clinic:
The primary aim of the consultation in this clinic is to understand the underlying cause for the tinnitus and choose appropriate management strategy. Patients undergo detailed assessment including a range of audiovestbular tests and imaging (MRI / CT) if necessary. Treatment measures are tailored to suit the individual patient.  Some patients may require medication and others will be referred for hearing aid(s) if appropriate. Some patients may require long term rehabilitation / therapy which will be offered in a separate audiologist led clinic (THTC).

Paediatric Audiovestibular Clinic:
Children of all ages with hearing loss, and related problems such as speech & language delay, or communication difficulties are seen in this clinic.  A comprehensive assessment will be carried out. Sometimes this may require a few appointments before we arrive at a conclusion. The objectives of these assessments are,

  1. to ascertain the nature and the extent of the problem (type and degree of hearing loss)
  2. to evaluate the impact on child’s development and progress (Speech & Language and Communication)
  3. to explore the underlying cause (aetiology) of the hearing loss

The process may involve hearing tests of family members (parents & siblings), blood tests, saliva tests, urine tests, brain & kidney scans, genetic test etc.

As a part of the evaluation children with hearing loss will be screened for any balance problems and some children may require a comprehensive vestibular assessment. 

Where necessary, children will be referred to the ENT Clinic, Child Development Clinic, Ophthalmology (eye), Clinical Genetics and Speech and Language.  If necessary they will be fitted with hearing aids or referred for Cochlear implant assessment.

Children of any age with speech and language delay will be assessed in detail to exclude hearing related issues especially auditory neuropathy spectrum disorder (ANSD).  We also screen older children (above seven years) for suspected auditory processing disorder (APD).

Adults with hearing problems:
Adults with hearing and related problems will be assessed comprehensively to find out nature of the hearing loss and its impact on daily life. The primary aim of this clinic would be to explore the causes of the hearing loss. This process may require blood tests, MRI / CT scan brain etc. In addition to carrying out aetiological investigations, we provide information about assistive hearing devices, hearing protection and ‘hearing tactics’.  Where necessary, patients will be offered a referral for rehabilitation with hearing aids or cochlear implants.
