A nail matrix biopsy is a surgical procedure where a tissue specimen is obtained from the nail matrix, which consists of specialized cells that produce the nail plate. This procedure is usually done to diagnose or confirm a disorder affecting the nail plate. While nail biopsies are not common, they are often the only way to obtain a diagnosis. The recovery process after a nail biopsy involves potential risks such as bleeding, infection, nerve damage, and scarring. The nail plate is vulnerable to damage and can be supported with tape. The literature indicates that nail growth after surgical procedures or injuries depends on several factors, including the status of the nail and the type of damage. Complete regrowth typically takes between 5 to 10 months, with fingernails taking 4 to 5 months and toenails requiring a longer period of 10 to 18 months.

Nail regrowth after surgical avulsion takes 5-10 months
A nail biopsy is a surgical procedure to obtain a tissue specimen from the nail matrix, which consists of specialised cells that produce the nail plate. This procedure may be undertaken to diagnose or treat a disorder affecting the nail plate, such as inflammatory conditions, benign tumours, infections, or trauma.
One common procedure during a nail biopsy is nail avulsion, which involves the complete or partial removal of the nail plate. This provides the surgeon with access to the nail bed and the deeper germinal matrix for biopsy or treatment. The regrowth of nails after surgical avulsion typically takes between 5 to 10 months for both fingernails and toenails. However, some sources suggest that fingernails may regrow within 4 to 6 months, while toenails may take up to 10 to 18 months.
The rate of nail regrowth after avulsion can vary depending on several factors. One factor is the status of the nail, whether it is intact or avulsed. Additionally, the degree and type of damage to the nail and the germinal matrix can influence how the nail regrows and whether deformities occur. To promote proper healing and regrowth, it is important to follow post-procedure care instructions, including keeping the wound clean and dry, changing bandages as directed, and avoiding strenuous activity for several weeks.
In some cases, the original nail or a prosthetic may be positioned over the nail bed after avulsion to protect it from infection and scarring. This can also help support the regrowth of a healthy nail. It is important to note that nail biopsy and avulsion procedures can lead to complications such as bleeding, infection, nerve damage, and scarring, which may impact the regrowth process.
Overall, while nail regrowth after surgical avulsion typically takes 5 to 10 months, the specific timeframe can vary depending on various factors, including the type of nail, the extent of the procedure, and proper post-procedure care.

Nail avulsion is a common procedure for ingrown toenails
A nail biopsy is a surgical procedure in which a tissue specimen is obtained from the nail matrix, which consists of specialised cells that produce the nail plate. While a nail biopsy can provide important diagnostic information, it can also lead to complications such as bleeding, infection, nerve damage, and scarring. In some cases, scarring of the nail matrix may result in permanent deformity of the nail plate.
Nail avulsion is a common procedure that can be performed for both diagnostic and therapeutic reasons. It involves removing the entire nail, providing access to the nail bed and the deeper germinal matrix for biopsy if needed. One of the most common indications for nail avulsion is ingrown toenails, a condition where the toenail grows into the skin, causing pain, damage, and infection.
Ingrown toenails can be treated through a procedure called partial nail avulsion, which involves removing a portion of the toenail from its nail root. This technique specifically targets the part of the nail that is cutting into the sides of the skin. Partial nail avulsion is a minimally invasive method that can be performed in a clinic setting, typically taking less than 30 minutes. It is generally safe for young and healthy individuals with recurrent ingrown toenails. However, it is not recommended for individuals with certain conditions, such as diabetes with diabetic foot complications.
While partial nail avulsion can provide relief from pain and infection, it is important to note that it does not prevent the nail from growing back. Recurrence of ingrown toenails is common, as the underlying nail root remains functional. To achieve a long-term solution, a chemical matrixectomy can be performed following partial nail avulsion to destroy the nail root completely. This combined procedure has proven highly effective with low recurrence rates.
After nail avulsion, the regrowth of nails typically takes a considerable amount of time. For fingernails, complete regrowth can be expected within 4 to 5 months, while toenails may take up to 10 to 18 months. In some cases, regrowth may take even longer, depending on various factors such as age, health status, and the degree of damage to the nail.

Nail biopsy can cause scarring and permanent nail deformity
A nail matrix biopsy is a surgical procedure to obtain a tissue specimen from the nail matrix, which is a crescent-shaped structure at the base of the nail that produces the nail plate. The procedure is often employed to diagnose or rule out melanoma in patients with longitudinal melanonychia originating from the matrix.
Nail matrix biopsies are considered the most technically challenging type of nail biopsy, with a heightened risk of scarring. The nail matrix is very delicate, and any inadvertent or excessive damage to the matrix can result in permanent scarring and nail deformity. Scarring of the nail matrix is common and may lead to permanent deformity of the nail plate, also known as nail dystrophy.
To minimise scarring and nail dystrophy, biopsies should be performed on the distal matrix whenever possible as it is responsible for producing the undersurface of the nail plate. The distal matrix is less likely to produce scarring compared to the proximal matrix. Careful planning and precise targeting of the biopsy can also help to avoid undesirable complications and permanent damage to the matrix tissue.
While nail deformities can occur if the germinal matrix is damaged during a surgical avulsion, the nail plate typically regrows after such procedures. The literature indicates that the rate of nail growth varies and can take anywhere from 4 to 10 months for complete regrowth, depending on various factors such as the status of the nail and nutritional status.

The nail plate is placed back to improve healing and minimise pain
The nail plate is a protective plate found at the tip of the digits (fingers and toes) of primates. It is made of a tough rigid protein called alpha-keratin. The nail plate is the visible hard nail area from the nail root to the free edge. The nail matrix, which consists of specialised cells that produce the nail plate, is located at the end of the digit (finger or toe) under the skin beyond the distal phalangeal joint.
During a nail matrix biopsy, the nail plate is separated from the nail bed to allow a direct view of the nail matrix, enabling a precise targeted biopsy of the lesion. After the biopsy, a suture is placed to hold the nail plate back onto the nail bed. This is done to improve healing and minimise pain. The nail bed is highly innervated, and removal of the nail plate can be extremely painful.
In the case of a nail avulsion, where the nail is completely removed, the original nail or a prosthetic is placed over the nail bed to protect it from infection and scarring. This also helps to inhibit defect and deformity of the nail plate.
After a nail biopsy or avulsion, the nail will usually start to grow back within several weeks. The regrowth process can take between 4 to 18 months, depending on the type of nail and the status of the nail bed.

The nail bed is vulnerable to popping off after sutures are removed
A nail matrix biopsy is a surgical procedure in which a tissue specimen is obtained from the nail matrix—the end of the digit (finger or toe) under the skin beyond the distal phalangeal joint. The procedure can be used to diagnose or confirm a disorder affecting the nail plate, such as nail psoriasis, lichen planus, benign tumours, or a pigment band in the nail plate.
During the procedure, the nail plate is separated from the nail bed, and a suture is placed to hold the two together. After removing the sutures a week later, the nail plate is vulnerable to "popping off" and can be supported with tape.
Nail beds are vulnerable to injury, with fingertip injuries being the most common hand injuries. The nail provides protection for the fingertip and allows for tactile sensation. Injuries to the nail bed can be caused by crushing, such as with a hammer or a car door, and can result in nail separation or onycholysis.
In the case of nail separation, the nail peels away from the nail bed, often after an injury to the nail. This condition usually does not cause pain, but fungal infections can result in pain and irritation. Treatment for nail separation may involve cutting away the separated nail as it grows out, taking antifungal medications, or discontinuing certain nail products.
Nail avulsion is a common procedure that provides surgeons access to the nail bed for biopsy. Following surgical avulsion, nails typically take between 5 to 10 months to regrow, with fingernails taking 4 to 5 months and toenails requiring 10 to 18 months.

Frequently asked questions
Yes, nails do grow back after a biopsy.
The reported time for full regrowth ranges from 5 to 10 months for both fingernails and toenails. Toenails take longer, requiring 10 to 18 months to fully regrow, while fingernails typically take 4 to 5 months.
To avoid defects, the original nail or a prosthetic is placed over the nail bed to protect it from infection and inhibit scarring.
Nail bed biopsies are technically demanding and carry a risk of inadequate specimens, damaged samples, and nail dystrophy due to injury to the distal matrix. Postoperative pain and discomfort are proportional to the extent of nail plate removal.
