Dysphonia (Hoarseness of Voice)
Voice & Swallowing Problems
Larynx & Laryngology
The larynx, commonly known as the voice box, is a part of the respiratory system located in the throat. It houses the vocal cords, which are essential for speech production. The space between the vocal cords is the glottis which opens and closes to regulate airflow and produce different sounds. The larynx also plays a crucial role in preventing food and liquids from entering the airway during swallowing. This is done with the help of the epiglottis which is a leaf-shaped flap-like cartilage that sits above the glottis.
Common laryngeal pathology includes voice and swallowing disorders, and laryngeal cancer. Laryngitis, vocal nodules, and polyps can affect the function of the larynx and impair speech; while damage or dysfunction of the larynx can lead to difficulty swallowing (dysphagia) and aspiration (food or liquids entering the airway). Tumours can also develop in the tissues of the larynx, often affecting speech and requiring surgical intervention.
The branch of medicine that focuses on the diagnosis and treatment of disorders and diseases of the larynx, is called laryngology. Laryngologists use special diagnostic tools to ascertain the problem:
Laryngoscopy - direct visualisation of the larynx using a flexible or rigid endoscope to assess structure and function
Videostroboscopy - specialised examination technique using strobe light to visualise vocal cord vibrations and assess mucosal wave patterns
Imaging Studies - CT scans, MRI, and ultrasound may be used to evaluate laryngeal anatomy and pathology
Voice Analysis - objective measurement of voice parameters to assess vocal function and monitor treatment outcome
Dr Naveed Basheeth & Laryngology
As part of his subspeciality interest, Dr Naveed Basheeth has been treating patients with pharyngeal pouch via either endoscopic stapling or external approach excision, depending on the indications. His passionate team of dieticians, and speech and language therapists dedicatedly help patients with pre- and post-op care ensuring patients they are in good hands.
He is also one of the very few surgeons who performs laser surgery for both cancer and non-cancer pathologies of the voice box in the Lower North Island, New Zealand.
