Congenital nevus surgery is performed in a hospital setting or an accredited surgery center. The operating room is maintained to a strict sterile standard to prevent infection, which can be catastrophic for implants like tissue expanders.
The room is warmed to protect pediatric patients from heat loss. Specialized pediatric equipment, from small IVs to specific airway tubes, is utilized. The team includes the surgeon, scrub nurses, and pediatric anesthesia specialists.
The induction of anesthesia is handled gently, often with a mask for children to drift off before an IV is placed. The anesthesiologist continuously monitors heart rate, oxygenation, and temperature.
Pain management begins during the surgery. Long-acting local anesthetics are injected into the incision sites to provide numbness that lasts for hours after the patient wakes up. This preemptive analgesia reduces the need for heavy narcotics later.
The surgeon makes precise incisions along the borders of the nevus or in the planned expansion zones. The dissection creates a pocket between the subcutaneous fat and the muscle fascia. This plane is relatively bloodless and preserves the nerves and blood vessels supplying the skin.
Great care is taken to handle the skin gently. Trauma to the skin edges can lead to necrosis. The dissection must be wide enough to accommodate the expander or to allow the skin flap to move freely without tension.
For tissue expansion, the deflated silicone balloon is rolled up and inserted into the pocket. The surgeon ensures it lies flat and has no kinks. The injection port is placed in a separate, accessible pocket under the skin.
The incision is closed in layers to create a water-tight seal. A small amount of saline is injected into the expander to test the system and take up the slack in the pocket.
The inflation phase begins 2 to 3 weeks after placement, once the incision has healed. Patients visit the clinic weekly. The nurse or surgeon locates the port through the skin and injects saline using a small butterfly needle.
This process stretches the skin. It can cause pressure or discomfort for a few hours, but it is generally well-tolerated. The skin is monitored for thinning or blanching, which indicates the expansion is proceeding too quickly.
Once the skin has expanded sufficiently (usually after 3 to 4 months), the second major surgery occurs. The expander is removed. The nevus is excised. The newly grown skin is advanced as a flap to cover the defect.
This is the reconstructive payoff. The surgeon tailors the flap to fit the defect, removing dog ears (puckers of skin) and contouring the fat to ensure a smooth transition. Drains are often placed to remove fluid from the large pocket left by the expander.
After surgery, the patient wakes up in the recovery room. The surgical site is covered with dressings ranging from simple gauze to compression garments. If a graft was used, a “bolster” dressing is sewn on to keep the graft still.
Monitoring for hematoma (blood collection) is critical in the first few hours. The patient is observed until they are awake, drinking, and pain is controlled. Most expander placements are outpatient; major flaps may require an overnight stay.
Pain control is multimodal. It includes oral narcotics for the first few days, combined with acetaminophen and ibuprofen. Muscle relaxants may be used during tissue expansion to prevent muscle spasms around the foreign object.
Keeping the surgical area elevated helps reduce throbbing and swelling. Cool compresses (never directly on a flap or graft) can also provide relief. The goal is to keep the patient comfortable enough to rest and eat.
During the expansion months, the child carries the weight and bulk of the fluid-filled balloons. This can be awkward and uncomfortable, especially when sleeping. Using extra pillows and soft bedding helps.
Parents must protect the expanders from trauma. Rough play or sports where the expander could be hit are restricted to prevent rupture or skin breakdown.
Parents are taught to inspect the incisions daily. Signs of infection include increasing redness, heat, fevers, or pus. For tissue expanders, any redness over the implant dome is an emergency sign of impending extrusion.
If a drain is present, parents learn to strip the tube and record the output. Drains are usually removed in the clinic once the fluid output decreases to a safe level.
Activity is strictly limited after surgery. No running, jumping, or heavy lifting for several weeks. This prevents the incisions from pulling apart (dehiscence) and reduces the risk of bleeding.
For children with expanders, these restrictions last for months. They can attend school but must sit out of gym class. Protecting the skin from abrasion or puncture is paramount.
Simple serial excisions and expander placements are usually outpatient procedures. Large rotational flaps, extensive grafting, or surgeries on very young infants may require a hospital stay of 1 to 3 days.
This allows the nursing staff to administer intravenous pain management and antibiotics, and to closely monitor the flap’s blood supply.

It is scarce. They are made of thick silicone. However, a sharp object (like a cat scratch or a needle) could puncture it. If it deflates, the saline is harmlessly absorbed by the body, but the device must be replaced surgically.
Most children report a feeling of pressure or “tightness” rather than sharp pain. A numbing cream (EMLA) can be applied to the skin over the port an hour before the visit to make the needle stick painless.
You usually cannot submerge in a bath. Sponge baths are required until the drains are removed. Once drains are removed and the wound is sealed, showers are permitted, but the area should be gently patted dry.
Yes. The skin has incredible elasticity. Once the expander is removed, the stretched skin is used to cover the wound, and the remaining skin contracts and settles over several months. It does not stay baggy.
Small openings (dehiscence) can happen. They are often treated with antibiotic ointment and dressing changes. However, if an expander is exposed through the wound, it is a serious complication that usually requires removing the device.
