Assessment of the voice requires a combination of subjective and objective measurements.

Subjective listening from a trained professional can provide very useful information and this is provided by Dr Theo as well as a team of speech pathologists and clinical voice consultants with extensive experience in voice care.

Objective assessment with acoustic analysis of voice parameters as well as visualisation of the larynx (voice box) and vocal folds is also critical.

Dr Theo has HD (high definition) video analysis equipment as well the first HD videostroboscopy system in Adelaide. This enables him to obtain the best possible view of the larynx possible and often leads to diagnosis which may be missed with the older fibre optic scopes. Most voice box surgery should not be performed without prior stroboscopy.


Soft swelling of the vocal folds which tend not to resolve spontaneously and may be related to trauma

Like other tissues in the body, as the larynx ages it can become weaker. It is possible to strengthen this with specialised exercises tailored to each patients voice box, however, there is also an adjunctive new method of treatment offered to some patients.

For those whose voice is important to their everyday function if it is starting to become weaker, then a simple injection into the vocal folds under local anaesthetic can make an immediate and dramatic improvement. This has been particularly helpful to public speakers and takes around 10 minutes.

Dr Theo offers this service either in the Adelaide city office or in a hospital operating room and is the first surgeon in Adelaide to be specially trained in this technique having performed hundreds of vocal fold injections both overseas and in Australia.





The voice box is one of the most delicate structures in the human body. There are a whole range of conditions which may require surgery. This can be performed delicately under general anaesthesia with microscopic guidance or comfortably under local anaesthesia with modern equipment.


Prior to any vocal fold surgery a formal assessment with HD videostroboscopy allows Dr Theo to individually plan and explain the steps and likely outcomes to each patient.


Dr Theo is the only fellowship trained sub specialist laryngologist (voice box) specialist in South Australia. He has extensive experience in all voice box surgery and uses the most modern techniques to provide world class outcomes.


Possibly the most difficult vocal fold condition to treat. This can be caused by voice over use, infection, previous surgery or even be present from birth


Potentially associated with significant stigma and anxiety amongst singers. These can be likened to callouses of the vocal folds and are generally caused by phonotrauma. Treatment requires voice therapy and may even require surgery with excellent results.


Vascular Ectasia

Occasionally in people on blood thinning medications or in singers prominent blood vessels can form and even burst. These adversely affect the voice and are best treated with the KTP laser.


Swelling beneath the lining of the vocal fold containing mucus or skin cells, these may be present from birth or occur at any time.

Treatment involves microsurgery and it is critical that they are removed by the gentlest possible method

Immobility / Paralysis

Vocal fold weakness can occur following surgery in the brain, neck or chest as well as a number of other conditions. This results in a weak breathy voice and even problems with swallowing (liquids particularly are difficult).

Dr Theo is passionate about treating vocal fold weakness appropriately and early.  There are now excellent simple short or long term treatments for this condition and patients do not need to suffer in silence.
