When should a hoarse voice be evaluated?

Hoarse voice lasting 2 weeks or more should be properly evaluated. Hoarseness includes alterations in voice quality, pitch, loudness and effort on speaking or singing. There are numerous causes ranging from common cold to voice box tumours. Comprehensive assessment involves taking a history of the voice problems and its degree of disability, and examination of the vocal folds (vibrating part of voice box) and surrounding structures. Detailed examination includes videostroboscopy using a telescope passed through the nose or mouth to visualise the vocal folds and their vibration in slow motion. Other tests sometimes include ambulatory pH monitoring to test for acid reflux and laryngeal electromyography to test nerve function. Dr. Lau manages the full spectrum of voice problems and hoarseness including occupational and professional voice.

What treatments are available for voice problems?

The choice of voice treatment and vocal surgery depend on accurately identifying the cause, and may involve:

  • Medication, including management of acid reflux
  • Speech therapy (we work closely with skilled speech therapists and offer home therapy)
  • Manual therapy (manual release of muscle tension)
  • Psychological therapy in specific instances
  • Botulinum toxin injection for spasmodic voice disorders (electromyography guided)
  • Injection medialisation and injection laryngoplasty for vocal paralysis (office-based or in-patient, using a variety of fillers and techniques).
  • Laryngeal framework surgery including medialisation thyroplasty for vocal fold paralysis
  • Surgery for spasmodic dysphonia
  • Microlaryngeal surgery (microsurgery of the voice box) for lesions on the vocal folds.
  • Laser surgery for benign and malignant conditions (e.g. laryngeal papillomatosis and early laryngeal cancer)
  • Outpatient secondary tracheoesophageal puncture (Dr Lau has developed a specialised technique for this)
  • Gender reassignment surgery

Voice disorders are an area of special interest to Dr Lau, who is one of the region’s leading ENT specialists in this field.
