Sterile Preparation and Positioning

The surgery begins with the patient under anesthesia. The head is positioned on a specialized headrest (often a “horseshoe” or gel ring) to allow access to the entire scalp while protecting the face and eyes. The hair is secured with sterile gel or rubber bands to keep it out of the wound.

The scalp is prepped with a sterile solution. If a skin graft or free flap is planned, the donor site (thigh, back) is also prepped. Draping is extensive to create a large sterile field, allowing the surgeon to move tissue freely without contamination.

  • Stabilization of the head and neck
  • Securing hair away from incision lines
  • Sterile preparation of the recipient and donor sites
  • Protection of the eyes and ears
  • Establishment of a wide sterile field

Debridement and Tumor Resection

PLASTIC SURGERY

The first surgical step is removing the pathology. For trauma, this means debridement—removing all dead, contaminated, or crushed tissue until healthy, bleeding edges are reached. Cancer involves excising the tumor with the pre-planned safety margins.

Intra-operative pathology (frozen sections) is often used. The excised tissue is sent to the lab immediately for margin evaluation. The reconstruction does not begin until the pathologist confirms that all cancer is gone. This ensures that cancer is not buried under a complex flap.

  • Aggressive debridement of necrotic tissue
  • En bloc resection of tumors
  • Intra-operative frozen section analysis
  • Confirmation of clear surgical margins
  • Copious irrigation to reduce bioburden

Galeal Scoring and undermining

To gain tissue laxity, the surgeon undermines the scalp, separating the galea from the periosteum. This allows the scalp to slide. If more length is needed, “galeal scoring” is performed.

The surgeon makes multiple parallel cuts on the underside of the galea (the tight fibrous layer) without cutting the blood vessels in the subcutaneous fat. This releases scalp rigidity, allowing it to stretch significantly (“accordion effect”) to cover the defect without tension.

  • Separation of the galea from the pericranium
  • Preservation of perforating vessels
  • Parallel incisions in the galeal fascia
  • Release of fibrous tension
  • Expansion of flap reach (1-2 cm per score)

Local Flap Design and Rotation

Based on the defect size, a local flap is designed. Standard designs include the Rotation Flap (curved arc), Transposition Flap (rectangular tongue), or the “Pinwheel” Flap (multiple rotating flaps). The flap is lifted, ensuring the identified artery is included in its base.

The flap is rotated into the defect. The geometry distributes the tension over a large area rather than focusing it on the wound edge. Standing cones of excess skin (“dog ears”) are trimmed or corrected to ensure a flat contour.

  • Design of rotation or transposition geometry
  • Elevation of the flap on a vascular pedicle
  • Rotation into the primary defect
  • Distribution of closure tension
  • Management of “dog ear” deformities

Skin Grafting (If Applicable)

If the defect cannot be closed with flaps, a skin graft is harvested. A dermatome (electric shaver) takes a thin sheet of skin from the thigh. The pericranium (membrane over the bone) must be intact to support the graft.

The graft is meshed (small slits cut into it) or applied as a sheet. It is secured with staples or sutures. A bolster dressing or Wound VAC is placed over it to press it firmly against the bed, preventing fluid from lifting it off.

  • Harvest of split-thickness skin graft
  • Preparation of the recipient bed (intact periosteum)
  • Meshing for drainage and expansion
  • Fixation with staples or sutures
  • Application of compressive bolster/VAC

Management of Exposed Bone

  • If the periosteum is missing and bare bone is exposed, a skin graft will not survive. The surgeon must modify the bone to allow healing. The outer table of the skull is burrowed down or drilled with small holes (“trephination”).

    This exposes the bleeding diploic space (marrow) of the skull. Over a few weeks, granulation tissue forms in these holes, creating a vascular bed that can eventually support a skin graft. Alternatively, a vascularized muscle flap is brought in to cover the bone immediately.

    • Burring of the outer calvarial table
    • Trephination (drilling) to expose diploë
    • Stimulation of granulation tissue growth
    • Staged grafting procedure
    • Immediate coverage with muscle flaps

Microsurgical Free Tissue Transfer

  • For massive defects, a free flap is performed. The latissimus dorsi muscle or anterolateral thigh flap is harvested. The surgeon uses a microscope to suture the flap’s artery and vein to the superficial temporal or facial vessels on the head.

    This is the most complex reconstructive tier. It requires precise vessel anastomosis using sutures thinner than a hair. Once blood flow is established, the flap turns pink. The donor muscle is then covered with a skin graft. This provides a thick, healthy cushion over the brain.

    • Harvest of distant flap (muscle/skin)
    • Microvascular anastomosis of vessels
    • Re-establishment of perfusion
    • Monitoring of flap viability (Doppler)
    • Closure of the donor site

Tissue Expansion (Insertion Phase)

  • If tissue expansion is chosen, this surgery involves placing the device. Incisions are made remote from the defect. A pocket is created under the galea. The uninflated silicone expander is inserted.

    The injection port is placed under the skin in an accessible spot. The wound is closed meticulously to prevent the device from extruding. No expansion is done immediately; the wound is allowed to heal for 2-3 weeks before inflation begins.

    • Creation of sub-galeal pockets
    • Insertion of silicone expanders
    • Placement of remote injection ports
    • Layered water-tight closure
    • Delay period before activation

Closure and Drains

Scalp wounds are closed in layers. The galea is sutured with high-strength, absorbable sutures to maintain tension. The skin is closed with staples or non-absorbable sutures. Staples are commonly used on the scalp as they are gentle on hair follicles and quick to place.

Suction drains are almost always placed under large flaps. The scalp can bleed significantly post-op, and a hematoma (blood collection) can kill a flap by putting pressure on the vessels. Drains remove this fluid and suck the flap down onto the skull.

  • Galeal closure to bear mechanical load
  • Skin closure with staples or sutures
  • Placement of closed-suction drains (JP drains)
  • Prevention of sub-galeal hematoma
  • Obliteration of dead space

Dressings and Head Wraps

  • A distinct “head wrap” or turban-style dressing is applied. It provides gentle, even compression to minimize swelling and support the flaps. It must be tight enough to prevent bleeding but not so tight as to compromise blood flow to the flap edges.

    The ears are carefully padded to prevent pressure necrosis. For free flaps, a “window” is left in the dressing so nurses can check the flap’s color and temperature without removing the bandages.

    • Application of bulky compressive dressing
    • Protection of the ears and forehead
    • Padding of pressure points
    • Monitoring windows for flap assessment
    • Instructions on keeping the dressing dry

Immediate Post-Op Monitoring

  • Patients are monitored in the recovery room. Head elevation (30-45 degrees) is mandatory to reduce venous congestion and swelling. Blood pressure is strictly controlled; too high causes bleeding, too low causes flap ischemia.

    For free-flap patients, monitoring is intensive (in an ICU setting). Hourly checks of the flap using Doppler or clinical exam are performed for the first 24-48 hours. Any sign of vascular compromise necessitates an immediate return to the operating room.

    • Head elevation protocol (30-45 degrees)
    • Strict blood pressure management
    • Hourly flap viability checks (Color/Capillary refill)
    • Management of post-op nausea (to prevent straining)
    • Pain control with non-sedating analgesics

FREQUENTLY ASKED QUESTIONS

Will I be in a lot of pain?

Scalp surgery is surprisingly well-tolerated. The scalp has many nerves, but once the initial healing begins, the pain is usually described as a tight headache rather than sharp pain. Tylenol and mild narcotics are usually sufficient after the first few days.

Those are surgical drains. They remove blood and fluid that collects under the skin. They are temporary and are typically removed within 2 to 5 days as drainage decreases. They prevent fluid pockets that could hurt the healing.

You must sleep with your head elevated on 2 or 3 pillows, or in a recliner, for the first 1-2 weeks. This uses gravity to drain swelling away from your face and head. Do not sleep on the side of the surgery to avoid pressure on the wound.

Typically, you can let water run gently over the incisions after 48 hours, but you cannot scrub or use shampoo vigorously. If you have a skin graft, you must keep it dry for about a week. Your surgeon will give you specific instructions for the timeline.

Gravity causes the scalp swelling to travel downward. It is very common to get black eyes or swollen cheeks 2-3 days after scalp surgery, even if the surgery was on the top of your head. This is normal and will resolve in a week.
