Toenail separation after an impacted toe nail can be practiced with a nail extraction to remove the damaged toenail. Under normal circumstances, the toenail acts as a tight, solid layer of keratinized skin that serves as a defense. When a toenail separates as a result of a traumatic injury, it loses its normal defensive function and can become infected. Therefore, it is recommended that a nail extraction procedure be performed to remove the damaged toenail and wait for a new one to grow. Nail extraction is one of the most common surgical procedures, in which the patient undergoes local anesthesia and is given a local nerve block, and then a scalpel and other instruments are used to separate the patient’s toenail from the nail bed, and then sterilized again. After the operation, it is necessary to pay attention to the prevention of infection and change the medicine regularly. The new toenail will grow back in 1~2 months after the surgery. The operation should be performed by a professional doctor. After the operation, you need to change the medicine regularly to avoid infection.
