Thickened and Overgrown Nails (Onychauxis Nail)

Sometimes, the toenails become so overgrown and thickened and are difficult to cut with conventional nail clippers. 

This nail disorder, known as onychauxis Nail (Thicken Nails) , is seen in older people or as a response to long-term pressure on the nails or a fungal nail infection and damaged.

Surgery may be recommended if your toenail doesn't improve from conventional nail cutting. Depending on the severity of your symptoms, this may involve removing part or all of your toenail. The nail can be removed to grow back or permanently removed.

Onychauxis Thicken Nail Surgery

The usual procedure is as follows:

The toe or finger is made numb and painless by injecting local anaesthetic into the base of the toe or finger.

The  toenail or fingernail that are thicken is cut right up to the base of the nail root and the offending  onychauxis thicken nail can then be pulled out.​

We wait for the nail to grow back and see if it grows back with the onychauxis thicken nail.

If the nail is permanently removed. A small amount of acid (called phenol) is often put on the exposed part of the nail bed. This helps to stop  the root of the nail from growing a full nail. (The nail surgery specialist will always discuss with you the best options.)​

The nail is then dressed.

Once the anaesthetic wears off the toe or finger may be sore so you may need mild painkillers such as paracetamol for a day or so.

After the operation, the nail surgery specialist or Podiatry assistant will review your nail surgery wound and teach you how to dress the toe or finger.

The nail removed can be sent to biopsy, PCR and culture for further diagnosis and treatment.
