Nail surgery, as a treatment option for nail fungus.
As a podiatrist I regularly do surgery on toe nails, usually to get rid of ingrown toenails, either by removing part or all of the nail. Recently I have been doing more surgery for treating nail fungus and patients have been pleased with the results.
Nail fungus is a very common condition in the feet and can be slow and sometimes difficult to treat. Fungus occurs usually following damage to the nail, this can be acute damage like stubbing your toe on something, or chronic damage caused by footwear. When this happens the nail will often separate from the skin and fungus can enter that space and start eating away at the nail making it crumbly, and discolored.
Common treatments can involve removing as much infected nail as possible and treating with a lacquer or liquid, this can be slow as the nail has to grow out while being treated. Systemic antifungals ( tablets like Lamisil) which can be effective but are not without potential side effects (particularly with liver and kidneys) and still take some months to work. Laser can be effective although an expensive option, my experience is that it works brilliantly on finger nails but is not consistent enough on toe nails to always justify the expense.
Here in Spain where many people wear open shoes for the majority of the year. Nail fungus can be embarrassing and unsightly. I am finding people are keen to try surgery as an option.
The surgery is performed under a local anesthetic known as a ring block. This is a little nerve block which makes the toe numb from the base all the way to the tip.
For fungus there are two ways of doing the surgery. The first one involves removing the whole nail and treating the bed of the nail with a very strong caustic (phenol) which basically kills the nail bed so it doesn't grow back. This is fail safe and is often used when the nail is very thick and damaged but it means you no longer have a nail just the outline of where it was. It also takes longer to heal and requires a dressing for 5-6 weeks following surgery. Although patients can still shower swim and lead a normal life they need to change the dressing each time it gets wet and bathe it in salt water.
The other approach still involves removing the nail but then no caustic is applied and once healed (in this case much quicker 4-5 days) the bed of the nail is treated with an antifungal while the nail grows back to kill the fungus deep in the nail bed.
