How effective is nail surgery for nail fungus?

A dermatologist may consider partial or complete nail removal when the nail is thick, painful, crumbling, or difficult to treat through its surface. Removing diseased nail material can make the toe or finger more comfortable and allow medication to reach the nail bed more easily. The new nail still grows slowly, and its appearance depends on whether the nail-producing area was affected.

Surgery does not identify every cause of a discoloured or thick nail. A sample may be recommended before treatment because trauma, psoriasis, and other nail disorders can look similar to fungal infection.

Ask whether testing is needed and which part of the nail should be removed. Follow the wound-care instructions, keep the area protected as advised, and avoid picking at the healing edge. Your clinician may recommend an antifungal treatment for the nail bed, skin, or footwear, depending on the confirmed diagnosis. Arrange follow-up if the nail remains painful or the new growth is abnormal.

Contact a clinician promptly for spreading redness, increasing warmth, pus, fever, worsening swelling, or pain that is not settling. People with diabetes, poor circulation, reduced sensation, or a weakened immune system should seek individual advice early for any nail wound.

Ask: Has the fungus been confirmed? Is removal partial or complete? How will the nail bed be treated? What signs suggest infection after surgery? How will we judge improvement while the nail grows?
