Is your toenail constantly painful, infected, or just won’t heal no matter what you try?

Whether it’s a recurring ingrown nail, severe fungal infection, or nail trauma, you may have been told about something called nail excision. But what is it exactly? Is it painful? And how do you know when it’s the right choice?

This blog walks you through when nail excision becomes necessary, what happens during the procedure, and how to care for your toe or finger afterward, so you can take the next step confidently.

What Is Nail Excision?

Nail excision (also called nail avulsion or nail removal) is a minor surgical procedure where part or all of the nail is removed, typically from a toe, often the big toe.

There Are Two Main Types:

Partial Nail Excision (PNA): Only the affected portion of the nail is removed.
Total Nail Excision (TNA): The entire nail is removed, usually when the nail bed is extensively involved.

Sometimes, chemical cauterization (phenolization) is used to prevent the regrowth of the problematic part of the nail permanently.

When Is Nail Excision Necessary?

Not every nail issue needs surgery. But excision becomes necessary when:

Ingrown toenails keep recurring, despite conservative care
There’s a severe infection or abscess formation
You have a fungal nail that’s unresponsive to medication
The nail is thickened, deformed, or painful due to trauma
There’s a subungual hematoma (blood under nail), causing pressure
Suspected nail tumors (benign or malignant) need biopsy or removal

If walking becomes painful, shoes hurt your toe, or you can’t trim the nail properly, it’s time to consult a specialist.

What Happens During a Nail Excision Procedure?

Here’s what to expect step by step:

✅ Before the Procedure:

Area cleaned and numbed with local anaesthesia
You’ll feel pressure but no pain

✅ During the Procedure:

The nail (partial or full) is carefully lifted and removed
If permanent removal is needed, phenol or sodium hydroxide is applied to the nail matrix
Wound is cleaned, dressed, and protected with a light bandage

Procedure time: 30–45 minutes

Stitches: Usually not needed

What Is Recovery Like?

Recovery is generally quick, but some care is needed.

First 24–48 Hours

Keep foot elevated
Apply prescribed antibiotic cream
Change dressing as instructed
Avoid getting it wet

1–2 Weeks

Wear open-toed or roomy footwear
Walking is usually okay after a couple of days
Mild oozing or soreness is normal

Full Healing

Partial excision: ~2–3 weeks
Total excision: ~6–8 weeks
Regrowth: May take 3–6 months (if not permanently removed)

Is Nail Excision Painful?

Nope—you won’t feel pain during the procedure thanks to local anesthesia.

Post-procedure soreness is usually mild and manageable with over-the-counter pain relievers like paracetamol or ibuprofen.

Will the Nail Grow Back?

If no chemical is used: The nail will regrow—but may take months

If the matrix is cauterized, that portion of the nail is permanently removed

This helps prevent repeat ingrown nails or other chronic issues.

Top Tips for Smooth Healing

Keep the area clean and dry
Don’t force off any crust or scab
Avoid tight shoes during recovery
Follow up if there’s redness, pus, or worsening pain

A topical antifungal or antiseptic may be advised for ongoing protection.
