Congenital Nevus: Post-Surgery Care and Scar Management - Surgery

More Info

---

Understanding congenital nevi, particularly congenital melanocytic nevi (CMN), is essential for both medical professionals and patients. These nevi are pigmented lesions present at birth, and while they are generally benign, they can grow in size as the child develops. The decision to surgically remove a CMN, especially if it is large or has changed in appearance, is often made to rule out malignancy and for cosmetic reasons.

Post-surgery care is crucial for optimal healing and minimizing scarring. After the excision of a CMN, it is common for patients to experience itching and redness around the surgical site, especially within the first few weeks. The use of silicone gel sheets or silicone gel, often referred to as "beauty tape" or "scar tape," is a common recommendation for scar management. These products can help flatten and soften scars, but they may also cause irritation in some individuals, leading to redness or rashes.

In your case, since you are experiencing significant itching and redness around the area where the silicone gel is applied, it may be wise to discontinue its use temporarily. Instead, you could consider using a hydrocolloid dressing or artificial skin, which can provide a protective barrier while allowing the skin to breathe. These dressings can help manage moisture levels and protect the area from external irritants.

Regarding the use of scar treatment products like polyxal (or other silicone-based scar gels), these can be beneficial once the wound has fully healed and there are no open areas or drainage. Typically, these gels should be applied to clean, dry skin. You would want to apply a thin layer over the scar and gently massage it in. It's usually recommended to apply the gel twice daily for several weeks to months, depending on the severity of the scar and the product's instructions.

It's also important to monitor the scar for any changes. If the redness persists or worsens, or if you notice any signs of infection (such as increased warmth, swelling, or discharge), you should consult your healthcare provider. They may recommend a topical corticosteroid to reduce inflammation or other treatments to address the irritation.

In summary, after the excision of a congenital nevus, careful post-operative care is essential. If silicone gel is causing irritation, consider switching to an alternative dressing. Once the area is fully healed, you can start using scar management products like silicone gel. Always consult your healthcare provider before making changes to your post-operative care routine, especially if you have concerns about your healing process or the appearance of your scar.
