Nail Avulsion

Total nail removal or avulsion is indicated in:

1. Long standing fungal nail infection not responding to treatment such as topicals or oral antifungals. The nail can be removed surgically or by way of application of a chemical usually left on for a week. 

2. Subungal hematoma – The procedure is not commonplace for this condition unless blood under the nail is causing too much pain or the nail is already partially dislodged from nail bed causing discomfort or inconvenience. 

After the nail is removed it can be quite sensitive and needs good aftercare.

Partial nail removal or avulsion is indicated in:
  1. Ingrown toenails 
  2. Pincer nails especially if causing pain on weight bearing 
The procedure is performed under local anaesthesia. 
 
The side of the nail that is ingrown or pincered is removed with a surgical scissors. We have to ensure that the proximal nail matrix (which houses our nail cells) is exposed such that phenol can be applied onto it. Without doing so, the nail will regrow with the same problem again. 
 
White soft paraffin is applied around the nail folds to protect from the chemical irritating the skin. 
 

There will be a dressing applied that may need to be changed twice a week.

Chemical Nail Removal

Concentrated Urea is applied onto the affected nail. This is preferably left on for around a week with a dressing. Although, sometimes the dressing inevitably falls off especially for smaller nails.

Subsequently, the nail becomes soft and brittle enough for removal by paring. This non-surgical option has lesser pain and downtime but may need to be repeated again especially if some parts of the nail are too thick.

This treatment is done for recalcitrant fungal nail infections failing topical antifungal treatment and sometimes oral medications. The procedure has small risk of causing irritation to the skin on the sides of the nail.
