The voice is an indispensable source of human communication. Current time puts high demands on the quality of voice in most professions. Organic or functional changes of vocal cords associated with their insufficiency lead to a deterioration of voice quality, voice fatigue, hoarseness or breathing difficulties. This has adverse psychological, social and economic consequences for the patient, the employer and its surroundings. The injection techniques can be performed under general and local anaesthesia. The defined injectable substance is inserted directly in the vocal cords, which increases its volume and results in an almost immediate improvement of the voice quality. For injection can be used various materials, e.g. autologous fat, calcium hydroxyapatite, silicone, and others. Injection techniques are less invasive, associated with less perioperative morbidity. Operation can be also performed under local anaesthesia in selected patients, therefore is preferred for patients with multiple comorbidities and risk of general anaesthesia.
