Conditions affecting the ear: from hearing loss to tinnitus and vertigo

Hearing disability in children, audiological investigation of deafness, sudden hearing loss, tinnitus and fitting of hearing aids – find out more about possible investigations and treatment at the ENT practices in Zug and Lucerne.

Hearing disability in children

  • Very rarely congenital (present from birth)
  • The most common cause of hearing problems is a blocked Eustachian tube with catarrh
  • Glue ear (secretory otitis media), often associated with enlarged adenoids                     

One of the special interests at our ENT practices is the investigation and treatment of children. Not only do we focus on the needs of our young patients but we are also aware of the questions and worries that concern you as parents. Our expertise includes newborn hearing screening tests, the diagnosis of childhood hearing disability and delayed speech development, but we also treat childhood conditions of enlarged adenoids, polyps, infections and allergies.

The diagnostic investigation of ENT disorders in children makes special demands on staff and equipment. We offer investigations performed by specially trained staff using state-of-the-art technology. Highly specialised assessments of delayed speech development and brain stem audiometry (BERA) are carried out in paediatric audiology in the ENT department, Lucerne, led by Dr Peter Opperman.


  • Hearing tests  
  • Speech audiometry (with words and numbers)  
  • Tympanometry / Impedance measurement 
  • Otoacoustic emissions (OAE) and their distortion products  
  • Newborn hearing screening test 
  • Diagnosis of delayed language development 
  • Allergy testing  
  • Endoscopy of the nasopharynx in children 
  • Ultrasound (ultrasonography)


Our ENT practice has a special focus on the treatment of patients who suffer from deafness/sudden hearing loss and other disorders of hearing or troublesome noises in the ears (tinnitus).

Treatment of advanced hearing loss often requires the patient to be fitted with a hearing aid, sometimes also by replacing part of the middle ear with a cochlear implant (a prosthesis for deaf people). It is often difficult to find exactly the right hearing aid and needs us to work in close cooperation with the hearing aid technician. Professional advice helps every patient to find the right solution..


  • Various hearing tests to determine the ability to hear (degree of deafness/hearing loss) 
  • Speech tests 
  • Fitting and checking of hearing aids 
  • Tympanometry / Impedance measurement 
  • Otoacoustic emissions (OAE) 
  • Distortion product otoacoustic emissions (DPOAE) 
  • Tinnitus testing 
  • Supply of tinnitus maskers


Neuro-otology includes the investigations of balance disorders (dizziness, vertigo, staggering, tendency to fall) and disturbances of taste or smell (loss of taste, unpleasant taste or alterations in taste; loss of sense of smell, altered sense of smell).


There are many possible causes of vertigo (dizziness). We need to find out whether it originates from the inner ear or whether other causes are responsible. It may be necessary to involve specialists from other disciplines as there are so many different reasons for dizziness.


  • Diagnosis of vertigo/dizziness using Frenzel goggles 
  • Positional tests  
  • Calorimetry 
  • Video nystagmography (VNG)  
  • Tests of smell
