Hoarse voice can range from being mildly hoarse, or debilitating as patients feel they have difficulty being understood.
Causes of a hoarse voice could range from muscle tension, acid reflux, benign cyst or nodules, neurological conditions causing weakness, ageing, or more worryingly a cancerous growth.
A camera test (nasolaryngoscopy) is mandatory in order to view the voicebox. If there is any growth seen, then a procedure for biopsy would be needed.
If the benign growth is the cause of the hoarse voice, then removal of the growth would improve the voice. In most cases, a course of voice therapy with the help of speech therapists can be helpful to restore some function of the voice.
