The FACE of Skin Cancer Treatment: Basal Cell Carcinoma and Mohs Surgery on the Forehead

basal cell mohs surgery forehead

Skin cancer is frighteningly common, with over 5 million cases diagnosed in the United States each year. 

While melanoma grabs headlines as the deadliest form, another type silently stalks sun-exposed areas like the forehead at an even higher rate. Basal cell carcinoma accounted for over 4 million cases last year alone, far outpacing any other skin malignancy. Fortunately, advanced techniques like Mohs surgery provide extremely high cure rates, even for complex basal cell carcinomas on delicate facial areas like the forehead.

What is Basal Cell Carcinoma?

Basal cell carcinoma arises from abnormal growth of basal cells, which reside in the outermost layer of the epidermis. Long term sun exposure can cause cumulative damage to these cells, leading to uncontrolled proliferation and tumor formation. 

The face is a frequent site, especially areas that see the most sun like the forehead, temples, nose, lips and ears. In fact, over 90% of basal cell carcinomas occur on the head and neck.

In the initial stages, basal cell carcinoma may resemble a pearly bump or pinkish patch of skin. As it enlarges, the center often becomes ulcerated and crater-like. Dark blood vessels are sometimes visible under the surface. The borders tend to be waxy, elevated and translucent. 

While the tumor rarely metastasizes, it can grow deeper and spread to surrounding tissue if not treated promptly.

On the forehead, basal cell carcinoma can be mistaken for a stubborn cyst, scar or pimple. Some warning signs specific to the forehead include:

  • Shiny pink, white or tan dome-shaped bumps with visible blood vessels
  • Persistent open sores with raised borders that won't heal
  • Pink or red scaly patches that may bleed with minor trauma
  • Waxy scar-like areas that are translucent when stretched
  • Crusting or oozing sores that may be itchy or painful
  • Persistent scab that won't heal normally after several weeks

Catching a developing basal cell carcinoma early on the forehead vastly simplifies treatment. Any suspicious sores or marks that linger longer than one month warrant evaluation by a dermatologist. A skin biopsy will confirm the diagnosis and appropriate therapy can begin before extensive growth or tissue damage occurs.

Mohs Surgery - The Gold Standard Treatment for Facial Basal Cell Carcinoma

While basal cell carcinoma is typically slow growing, tumors on the sensitive facial skin require special consideration. Standard surgical excision provides effective treatment for cancers elsewhere on the body. 

But the forehead's intricate network of sensory nerves and delicate tissue structures demand precise, tissue-sparing removal to avoid scarring and deformity.

That's where Mohs micrographic surgery delivers unmatched accuracy and cosmetic results. Developed in 1938 by Dr. Frederic Mohs, this technique offers the highest cure rate of any skin cancer treatment, up to 99% even for high-risk malignancies. It excels at eliminating basal cell carcinoma on aesthetically vital areas like the forehead while preserving healthy tissue.

The Mohs procedure, performed under local anesthesia in an outpatient setting, involves surgically removing the visible tumor and a thin layer of surrounding tissue. This removed tissue layer is meticulously mapped, color-coded, and examined under a microscope by the surgeon. 

If any cancer cells remain at the edges, the surgeon precisely targets the involved areas to take an additional tissue layer. This process repeats until the microscope reveals a clear perimeter with no remaining cancer cells.

This method allows microscopic control and 100% margin visibility, ensuring no basal cell carcinoma remnants are left behind. Less tissue gets removed overall compared to other techniques because only cancerous zones undergo sequential excision. The unparalleled precision also leads to minimal scarring and optimal cosmetic results on delicate facial areas.

What to Expect With Mohs Surgery on the Forehead

The prospect of facial surgery can provoke anxiety for any patient. Understanding exactly what the procedure entails helps ease the mind. The basic Mohs surgery process on the forehead involves:

  • Arriving at the clinic and checking in for the procedure
  • Meeting with the surgeon to discuss the treatment plan and answer questions
  • Changing into a gown and washing the face thoroughly with an antiseptic cleanser
  • Lying comfortably on an exam table and receiving monitored anesthesia through an IV line or local injections
  • Feeling pressure and tugging during the tissue removal but no pain due to numbness
  • Having the surgical site covered with a pressure bandage after the cancer excision
  • Waiting about 1 hour between stages for microscopic analysis of the tissue sample
  • Allowing additional layers to be removed if cancer cells remain in the margins
  • Understanding that the process may require several stages if the tumor is large
  • Receiving instructions for at-home wound care and follow-up appointment schedule
  • Having any reconstructive procedures scheduled if necessary

Compared to standard excision, the surgery itself takes longer since tissue analysis occurs during the procedure. However, the total healing time is often faster with Mohs due to the tissue sparing nature.

Recovery After Mohs Surgery on the Forehead

Since Mohs preserves the maximum amount of healthy tissue, the recovery period is generally mild. Most patients experience:

  • Mild discomfort, bruising and swelling around the site for 1-2 weeks
  • An indented surgical wound, unless reconstructive surgery is performed
  • Possible numbness of the forehead lasting weeks or months as nerve endings regenerate
  • Temporary itching, tingling, or burning sensations as nerve regeneration occurs
  • Formation of a scab within 24 hours, which later falls off to reveal new pink skin
  • Removal of any stitches within 7-10 days
  • Redness that fades over several weeks as new blood vessels form
  • Gradual smoothing of scar tissue over 3-6 months

To promote proper healing, patients should:

  • Apply antibiotic ointment and change dressings as directed
  • Avoid picking scabs or soaking the wound
  • Take over-the-counter pain relievers as needed
  • Keep the head elevated on pillows to minimize swelling
  • Follow any instructions for flap or graft care if reconstructive surgery was done
  • Avoid vigorous exercise and sun exposure until cleared by the surgeon
  • Report any signs of infection like oozing pus, increased pain or redness
  • Keep all follow up appointments for wound checks and monitoring

With Mohs surgery, most small to medium forehead defects heal without major cosmetic deformity. But larger defects may need additional procedures for the best aesthetic outcome on exposed forehead skin.

Reconstruction of the Forehead After Mohs Surgery

One advantage of the Mohs technique is precise mapping of the surgical defect. This allows the reconstructive or plastic surgeon to optimize repair options. The ultimate goal is restoring natural contour and appearance of the forehead.

For small defects, careful wound edge alignment and stitches often suffice. Linear closures can work for longer narrow defects. But wider gaps or deep crater-like cavities warrant more advanced options. The reconstructive techniques can be summarized as: 

Primary ClosureStitching wound edges togetherFor small defects only
Skin GraftsTransplanting skin from another areaRisk of graft failure or mismatch
Local FlapsRepositioning adjacent forehead skinLimited tissue availability
Regional FlapsRotating nearby scalp skinRequires some hair removal
Distant FlapsMoving skin from neck, chest, etcStaged procedures, more complex

The forehead presents unique reconstructive challenges due to minimal tissue mobility across midline. But the rich vascular supply facilitates healing of flaps and grafts. The scalp also supplies abundant extra tissue along with hair follicles for ideal color and texture match. 

Common repair techniques include:

  • Bicolumnar forehead flap - Skin pivoted from lateral forehead areas
  • Gullwing flap - Scalp tissue swung down as a pedicle flap
  • Scale flap - Skin recruited from the hairless brow ridge
  • Hairline flap - Scalp tissue advanced to fill a central defect

Forehead reconstruction ranges from simple same-day procedures to multi-stage operations spanning weeks or months. Your Mohs surgeon will advise on repair options and optimal timing after considering defect size, location, depth and other factors. 

Some patients may benefit from input of a specialized facial plastic surgeon. But with current techniques, even significant forehead and brow defects after Mohs surgery can be well concealed.
