Nail avulsion is a procedure that involves removing an ingrown nail. Depending on the type of avulsion, the nail may or may not grow back. A partial nail avulsion, for example, does not prevent the nail from growing back, whereas a partial nail avulsion with chemical matrixectomy will destroy the nail root, preventing regrowth. The time it takes for a nail to grow back after avulsion ranges from 4 to 18 months, with several factors influencing the rate of growth, including age, nutritional status, and the status of the nail (intact or avulsed).

What You'll Learn
Surgical nail avulsion
Nail avulsion may be used for diagnostic purposes, such as exploring the nail bed, nail matrix, and nail folds, or before performing a biopsy on the nail bed. It can also be used therapeutically to treat various nail pathologies, including onychocryptosis (ingrown toenail), warts, onychomycosis (fungal nail infection), chronic paronychia, nail tumours, matricectomy, and retronychia.
The recovery time for nail regrowth after surgical avulsion varies. Fingernails typically take 4 to 6 months to grow back, while toenails can take twice as long, ranging from 10 to 18 months. However, some sources state that toenails take about 12 months to regrow. The new nail may have grooves or ridges and may be somewhat misshapen, which could be permanent.
Chemical nail avulsion is an alternative to surgical nail avulsion. It involves the use of 40% urea ointments to slowly destroy and remove the nail plate. This method is painless and helps avoid the complications associated with surgical avulsion. However, it may not be completely successful in curing certain nail infections, as the fungi may persist in the nail matrix under the proximal nail fold.

Regrowth timelines
The regrowth timeline for fingernails after nail avulsion typically ranges from four to six months. During this process, the nail is expected to undergo various changes, resulting in a new nail that may exhibit grooves, ridges, and slight misshapen features. These characteristics might persist indefinitely.
For toenails, the regrowth period is generally lengthier, spanning a duration of ten to eighteen months. However, it's important to note that this timeline can be influenced by several factors, including age and nutritional status. Older individuals may experience slower nail growth, potentially reaching the higher end of the regrowth timeline or even extending beyond it.
Partial nail avulsion, commonly employed for ingrown toenails, does not prevent the nail from growing back. This is because the underlying nail root remains intact and functional. To achieve permanent nail removal, a chemical matrixectomy is performed in conjunction with partial nail avulsion. This procedure eradicates the nail root, effectively halting any future nail growth.
The rate of nail growth after surgical avulsion also varies across different fingers. Studies have reported a range of growth rates, from 0.050 to 0.150 mm/day, indicating faster or slower growth on specific fingers. Additionally, the thickness of nails tends to increase with age, which can further influence the overall regrowth timeline.
It is worth noting that these timelines are approximate and that individual factors can influence the speed of nail regrowth. Factors such as age, nutritional status, and overall health can impact how quickly a nail grows back after avulsion. In some cases, medical conditions or other external factors may also play a role in the regrowth process.

Ingrown toenail surgery
Ingrown toenails are a common and painful condition that can affect individuals at various stages of their lives. The condition arises when the toenail, usually on the big toe, grows into the adjacent skin, causing pain, swelling, and redness. While non-surgical treatments should always be attempted first, ingrown toenail surgery may be necessary for those who do not find relief through conservative methods.
There are several types of ingrown toenail surgery:
- Nail avulsion or nail-bed ablation: This is the most common procedure and involves removing the ingrown section of the nail. In some cases, a chemical or laser may be applied to inhibit regrowth. If the entire nail is removed, the recovery time is typically 10 to 12 weeks.
- Wedge excision: This procedure involves removing the part of the nail that is growing into the skin, along with the underlying nail matrix tissue to prevent regrowth.
- Complete toenail removal: Reserved for severe or recurrent cases, this procedure involves the complete removal of the toenail under local anesthesia.
- Partial toenail removal: This method is used for severe or infected ingrown nails. The doctor will numb the toe and remove a portion of the nail, but the nail will grow back within three months, and there is a chance of recurrence.
Regardless of the type of surgery, patients should expect to receive guidance on postoperative care to enhance healing and prevent complications. This may include elevating the foot, taking prescribed medications, proper wound care, and avoiding strenuous activities. It is important to follow the advice of healthcare professionals to ensure optimal healing.
The regrowth of toenails after surgical avulsion typically takes 10 to 18 months, with a combined range of regrowth observed at 5 to 10 months. The new nail may have grooves or ridges and may be somewhat misshapen, which could be permanent.

Preventing nail regrowth
While it is possible for nails to regrow after nail avulsion, there are a few measures that can be taken to prevent nail regrowth. Here are some ways to inhibit nail regrowth after nail avulsion:
Keep the nail bed protected
The nail bed is the area of skin underneath the nail. It is important to keep this area protected to prevent regrowth. One way to do this is to apply a special type of material, such as a prosthetic nail, to the nail bed. This will help inhibit synechial scarring of the ventral to dorsal germinal matrices and protect the nail bed from infection. Keeping the original nail or a prosthetic nail in place can help prevent regrowth by inhibiting the nail plate from regenerating.
Treat the underlying cause
Nail avulsion is often performed to treat underlying conditions such as ingrown toenails, chronic onychomycosis, periungual warts, trauma, infections, or tumors. By addressing and treating the underlying cause, the need for nail avulsion may be reduced, and future nail regrowth may be prevented.
Consider the growth factors
The rate of nail growth after avulsion can vary depending on several factors. Age, for example, can influence nail growth, with older individuals experiencing slower nail growth. Additionally, nutritional status can impact nail growth rates, as indicated by studies showing that fingernails in adults typically regrow within 4 to 5 months, while toenails take twice as long, ranging from 10 to 18 months. Understanding these growth factors can help guide decisions on preventing nail regrowth.
Protect the nail and digit during healing
After nail avulsion, it is important to protect the nail and digit during the healing process. This can be done by using a splint or a special shoe to keep the area immobilized and protected. Additionally, keeping the hand or foot elevated above the level of the heart can help reduce throbbing and promote healing.
Manage pain and inflammation
To promote comfort during the healing process, it is important to manage pain and inflammation effectively. Prescription pain relievers, ibuprofen, or naproxen can be used to reduce pain and swelling. Acetaminophen can also be taken for pain relief, although it may not help with swelling. It is important to consult with a healthcare provider before taking any medication, especially if there are underlying health conditions.

Nail injuries
In the case of a nail avulsion, where the nail is completely or partially removed, the nail bed will typically heal within 7 to 10 days. The time it takes for a new nail to grow back can vary depending on various factors. For example, the regrowth period for fingernails is estimated to be between 4 and 6 months, while toenails can take up to 12 months or longer. The regrowth rate after a nail avulsion procedure can also depend on factors such as age, nutritional status, and the status of the nail (intact or avulsed).
Partial nail avulsion is a common procedure for ingrown toenails, which often requires multiple treatments due to the underlying nail root still being functional. To prevent regrowth, a chemical matrixectomy can be performed to destroy the nail root. This procedure is safe and effective, but it is important to avoid activities that may delay wound healing. Patients are advised to avoid weight-bearing activities and enclosed footwear for about a week following the procedure.
Following a nail injury or surgery, it is important to keep the area clean and to take steps to prevent infection. Antibiotics may be prescribed to prevent or treat an infection. To reduce pain and swelling, it is recommended to apply ice and keep the affected area elevated. Over-the-counter pain relievers such as ibuprofen or acetaminophen can also be taken, but it is important to consult a healthcare provider if there are any concerns or pre-existing conditions.
