Advice after your nerve block for surgery

What is coblation?
Coblation technology is a surgical technique. It involves precisely removing tissue at cooler temperatures (40-70°C) compared to other technology like electrocautery (400-600°C).
It is increasingly preferred by ENT surgeons for removing adenoids and tonsils. It has been recommended by the NHS as part of GIRFT (Get it Right First Time) guidelines to treat sleep apnoea in children, due to lower risk, compared to the other tonsillectomy techniques available.
How is coblation adenoidectomy different?
Adenoidectomy is the partial removal or reduction of the tonsil-type tissue at the back of the nose. This is often done to improve nasal breathing, reduce post nasal drip, treat sleep apnoea (where there is poor sleep quality due to breathing being interrupted) and reduce infections where the adenoids are thought to be contributing.
Coblation adenoidectomy is only different in the technology used.
How is coblation intracapsular tonsillectomy different?
Tonsillectomy is the removal of tonsil tissue in the back of the throat. Traditionally tonsil tissue is removed up to the muscle layer, which then has to heal over time.
Coblation intracapsular tonsillectomy is different as it involves removing most of the tonsil tissue, but a thin layer of tonsil tissue is intentionally left, which allows for reduced risk of bleeding and less pain.
What are the advantages?
- Minimal damage to nearby healthy tissue
- Less blood loss
- Less pain
- Earlier return to your normal diet
- Quicker return to normal activities, including getting back to school.
- Reduces chances of re-attending A&E or of re-admission
What are the disadvantages?
There is a small (3 to 5 in 100) chance of your tonsils growing back or having recurring episodes of tonsillitis. If this happens, you will need repeat surgery in the future. This happens because of the layer of tonsil tissue left behind.
