Surgical removal is advised if moles change in shape, size, or colour, or if they cause irritation. Removed tissue is often sent for histological analysis to rule out malignancy.

Skin Surgery in Singapore
Dr. Liew Hui Min
Skin surgery encompasses procedures designed to remove, repair, or reconstruct areas of damaged, diseased, or unwanted skin tissue. These procedures treat medical conditions such as skin cancer, cysts, or chronic wounds, whilst also addressing cosmetic concerns that affect confidence and quality of life. The primary goal is to restore both function and appearance of the skin whilst minimising scarring and ensuring optimal healing.
Indications for Skin Surgery
Your dermatologist may recommend minor skin surgery in the following situations:
Moles (naevi)
Skin tags
These soft, benign growths can catch on clothing or jewellery. They are commonly removed for comfort or cosmetic reasons.
Seborrheic keratoses
These non-cancerous, wart-like lesions may be treated if itchy, irritated, or cosmetically bothersome.
Viral warts
Warts that are persistent or unresponsive to topical treatment may be removed surgically, with cryotherapy, or using electrocautery.
Cherry angiomas and spider naevi
These red, blood vessel-based growths may bleed or cause concern due to their appearance.
Pyogenic granulomas
Rapidly growing, red nodules that bleed easily may require surgical removal to prevent recurrence.
Skin cancers
Suspected or confirmed cases of basal cell carcinoma, squamous cell carcinoma, or melanoma require surgical excision to ensure complete removal of cancerous tissue and prevent spread.
Ingrown toenails
When part of the nail grows into the surrounding skin, it may cause chronic pain, swelling, or infection. Nail surgery removes the offending section and prevents recurrence.
Persistent or unclear rashes
When skin conditions do not improve with standard treatments, a biopsy may be needed. A small piece of skin is surgically removed to aid in diagnosis and guide further care.
Benefits of Skin Surgery
Definitive treatment: Complete removal of lesions eliminates the root cause rather than just managing symptoms.
Cancer detection and prevention: Early removal of suspicious lesions reduces cancer risk and allows timely intervention.
Symptom relief: Removing painful, itchy, or bleeding lesions improves physical comfort and quality of life.
Functional improvement: Surgery can restore movement or normal skin function in areas affected by scarring or overgrowth.
Diagnostic clarity: Histological examination of tissue provides a clear diagnosis, informing future treatment plans.
Skin Surgery Techniques and Methods
Several surgical techniques may be employed depending on the specific condition, location, and size of the area requiring treatment.
-
Punch Biopsy
A circular tool removes a small, full-thickness skin sample, often used to diagnose rashes or suspicious lesions.
-
Shave Excision
Superficial removal of raised lesions at skin level, commonly used for benign growths.
-
Ellipse (Simple) Excision
The lesion and a margin of normal skin are removed in an elliptical shape and closed with sutures.
-
Electrocautery and Curettage
Heat and scraping are used to remove lesions such as skin tags or viral warts, with minimal bleeding.
-
Nail Surgery
Partial or full nail plate removal to treat ingrown toenails or obtain nail biopsies.
Preparing for Your Skin Surgery
Proper preparation helps ensure your procedure proceeds smoothly and reduces the risk of complications.
Medical Evaluation
Your medical history will be reviewed, including current medications, allergies, and any bleeding disorders. Blood tests may be required for certain procedures or if you have underlying health conditions.
Site Preparation
Keep the skin clean. You may be advised to wash with antiseptic soap beforehand.
Smoking Cessation
Avoid smoking at least 2 weeks before and after surgery to support healing.
Transportation
Arrange for transport if sedation is involved or if surgery affects your ability to walk or drive.
What Happens During Your Skin Surgery
While each procedure is tailored to your specific needs, a typical surgical process often follows these general steps.
Initial Preparation
The surgical site is thoroughly cleaned with antiseptic solution, and sterile drapes are placed around the area. The surgeon marks the planned incision lines to ensure precision during the procedure.
Anaesthesia Administration
A local anaesthetic is injected into the skin around the treatment area to numb the region completely. You may feel a brief stinging sensation during injection, but the area becomes numb within minutes.
Tissue Removal
The surgeon carefully removes the affected tissue using the appropriate technique for your specific condition. The removed tissue is preserved for laboratory examination to confirm the diagnosis and ensure complete removal.
Bleeding Control
Any bleeding vessels are sealed using electrocautery or direct pressure, and the wound bed is inspected to ensure all targeted tissue has been removed.
Wound Closure
The wound is closed using the most appropriate method, which may include sutures, surgical glue, or skin adhesive strips. The choice depends on the wound size, location, and tension required for proper healing.
Dressing
A sterile dressing is applied to protect the wound and absorb any minor bleeding or drainage. You’ll receive instructions on when and how to change the dressing at home.
Recovery and Aftercare
-
First 48 Hours
Keep the area dry. Avoid strenuous activities that may stretch the wound.
-
1–2 Weeks
Sutures may be removed during this period. Redness or slight swelling is normal.
-
2–6 Weeks
Healing progresses, and scar tissue forms. Avoid direct sun exposure to prevent pigmentation changes.
-
3–6 Months
Final scar appearance improves over time. Continued skincare and sun protection help optimise results.
Potential Risks and Complications
Skin surgery is a safe and routine procedure when performed by a qualified dermatologist. Most patients recover smoothly with minimal downtime. Mild swelling, bleeding or bruising may occur but typically settles within days. Scarring is expected but often minimal with proper technique and care. Infections or allergic reactions are not common. In some cases, further treatment may be needed to fully address the lesion.
Frequently Asked Questions
Will I need time off work after skin surgery?
Most patients can return to desk-based work within 1-2 days, though this depends on the location and extent of your procedure. Physical jobs or those requiring heavy lifting may require several days to a week off work to allow proper healing.
Can I exercise after my skin surgery?
Light activities can usually resume within a few days, but avoid strenuous exercise, heavy lifting, or activities that stretch the surgical site for at least one week. Your dermatologist will provide specific guidance based on your procedure and healing progress.
How should I care for the surgical site at home?
Keep the dressing clean and dry, changing it as directed by your dermatologist. Avoid soaking in baths, swimming pools, or hot tubs until the wound has healed sufficiently, though gentle showering is usually permitted after 24-48 hours.
What signs should prompt me to contact my dermatologist?
Contact your dermatologist promptly if you notice increasing pain, swelling, spreading redness, pus-like discharge, separation of wound edges, or if you develop a fever. Early intervention can prevent minor issues from becoming more serious complications.
When will I know the results of my tissue analysis?
Laboratory results are typically available within 1-2 weeks of your procedure. Your dermatologist will contact you to discuss the findings and any additional treatment recommendations if necessary.
