What is Botox and how will it help me?
Botulinum Neurotoxin (Botox for short) is a biological toxin that has been found to inhibit the normal chemical messages that are sent from nerve endings to the muscle fibres throughout the body. In the case of spasmodic dysphonia, only the muscles that open and close the vocal cords are involved.
The procedure is done under local anaesthetic injection. A needle is then inserted into a soft area of the voice box and Botox injected into both vocal cords. The procedure takes only a few minutes. A monitor with electrodes placed next to you will guide the injection.
Symptoms post injection
You may experience minor swallowing difficulties for several days after injection. This will be the result of the injected toxin, which temporarily weakens the movement of the injected vocal cord so that it does not spasm as much when you speak.
Important: Please see your GP immediately if you develop a persistent cough or chest infection. This could be because some food or drink may be passing into your windpipe instead of your food gullet as you swallow. Your GP could prescribe a fluid thickening agent to help with this if required.
If you are having major problems swallowing food and drink, please contact the Speech and Language Therapy Department at Hull Royal Infirmary (01482) 604331 for advice during normal working hours on week days. Outside week day hours, or on week-ends please present to the Emergency Department at Hull Royal Infirmary.
If leaving an answer phone message with Speech and Language Therapy: please clearly state your name, telephone number and comment that you are a voice patient seeking advice about swallowing post Botox injection.
This can consist of foods such as mashed potato, casseroled or tender chunks of meat, processed sliced cooked meats (ham, chicken, etc), bread, rice, yoghurts, puddings, etc. Avoid hard foods such as toast, chips, cracker biscuits or large pieces of meat and combination foods (both liquid and solid in content) such as cereal with milk, (try yoghurt instead) and tinned fruits, unless using a thickener.
You can return to normal eating as soon as you feel confident to do so. This only takes a few days usually.
