What is Mohs Surgery?

Mohs surgery, named after Dr. Frederic Mohs, who developed it in the 1930s, is a specialized technique for removing certain common types of skin cancer, primarily basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). 

This procedure is distinct from standard surgical excision because the removed cancerous tissue is immediately examined under a microscope. This real-time analysis allows the surgeon to confirm whether all cancerous cells have been successfully removed while preserving as much healthy tissue as possible.

Why Is Mohs Surgery Considered Precise?

Several factors contribute to the precision of Mohs surgery:

• Microscopic Control: The surgeon can visually confirm if cancerous cells remain or if they have been fully excised.
• Conservative Tissue Removal: Cancerous tissue is removed in stages, minimizing the removal of extra healthy tissue.
• Minimal Scarring: By avoiding excessive tissue removal, scarring is reduced.
• High Cure Rates: Mohs surgery boasts cure rates of over 95%, with some sources reporting success rates as high as 99% for newly diagnosed skin cancers.
• Ideal for High-Risk Areas: The technique is particularly effective for delicate areas such as the face, neck, hands, feet, and genitals due to its conservative approach.

The ability to microscopically examine excised tissue is indeed the key advantage of Mohs surgery, ensuring that no cancer cells are left behind.

Essential Mohs Surgery Tools

Mohs surgery requires a unique set of surgical instruments to remove tissue layers precisely and examine samples microscopically. Here are the key tools used:

1. Microscopes

Two main types of microscopes are used in Mohs surgery:

• Stereomicroscope: To prepare specimens and examine surface details. This provides a 3D view.
  
• Compound microscope: To analyze the cellular details of specimens. This offers higher magnification.

After each stage of excision, the tissue samples are meticulously prepared, stained, and examined under both microscope types to identify any remaining cancer cells.

2. Blades and Scalpels

Scalpels and blades are used to precisely excise the tissue layers. Common types include:

• Curette blades: Sturdy, sharp blades ideal for scraping tissue.
• Razor blades: Provide the sharpest cutting edge.
• Scalpel handles: Reusable handles fitting disposable scalpel blades.

Our surgeon selects the appropriate blade for each excision stage, allowing controlled and incremental tissue removal.

3. Curettes

Curettes are instruments with oval-shaped tips used for tissue scraping and removal. Mohs surgeons use curettes in all stages of tumor removal. Types used include:

• Sharp curettes: Have cutting edges to scrape off tissue slices.
• Blunt curettes: Have dull, rounded edges suitable for scooping and probing tissue.

Curettes provide precise control when removing tissue layers and when scoping the margins after tumor removal.

4. Forceps

Forceps grasp and maneuver the tissue during excision. Common forceps used in Mohs surgery include:

• Toothed forceps: Have interlocking teeth to firmly grip tissue.
• Non-toothed forceps: Have flat, blunt tips to gently grasp tissue.
• Adson forceps: Offer fine, pointed tips for handling delicate tissues.

Forceps enable our surgeon to orient, transfer, and flatten out tissue specimens for microscopic analysis.

Other Tools

Additional specialized tools used in Mohs surgery include:

• Probes: Exploring and evaluating the wound margins.
• Scissors: Cutting and shaping tissue samples.
• Ink and markers: Mapping and marking the wound site.
• Hemostats: Clamping blood vessels for bleeding control.
• Retractors: Keeping the surgical area open and visible.

Understanding the Mohs Surgery Process

Step 1: Excision

Our surgeons begin by administering local anesthesia to numb the area. Then, they use a scalpel, curette, or razor to remove the visible tumor along with a thin layer of surrounding tissue. Forceps assist in handling the excised tissue. This first stage aims to remove the obvious cancer cells.

Step 2: Tissue Processing

The excised tissue samples are carefully cut, marked, and mapped. They are then processed for microscopic examination. This involves freezing the tissue and preparing it into thin sections for analysis.

Step 3: Microscopic Examination

The prepared slides of tissue are analyzed under both a stereomicroscope and a compound microscope to search for any remaining cancer cells. This step is crucial for determining if further excision is necessary.

Step 4: Mapping and Marking

If cancer cells are detected in the microscopic examination, our surgeons mark their exact location on a surgical map created during the initial excision. This mapping is essential for accurately identifying where additional tissue needs to be removed.

Step 5: Repeat Excision

Using the precise mapping from the previous step, our surgeons return to the marked areas to remove additional tissue only from locations still containing cancer. This cycle of excision and examination continues until no cancer cells remain in the surgical margins.

Step 6: Wound Closure

Once all cancerous cells have been cleared, they close the wound using sutures or other methods. The entire process may take several hours, often under four hours for a typical Mohs surgery session.

Recovery After Mohs Surgery

Recovery time after Mohs surgery varies based on factors such as the size and location of the removed cancer. Here’s what to expect during the recovery process.

1. Most wounds typically heal within 4-6 weeks, but delicate areas like the nose or eyelids may take longer. It is important to note that complete healing can take up to 12 to 18 months, especially for scars to fully mature and fade. 
2. After surgery, the wound will be bandaged. It is crucial to keep the site clean and change bandages as directed by your surgeon. Initially, it is recommended that the dressing remain undisturbed for 24 to 48 hours post-surgery to allow for optimal healing.
3. Sutures will be removed once the site shows signs of healing, which typically occurs within seven to fourteen days. The exact timing can depend on the wound's location and size.
4. Patients may be prescribed antibiotics, pain relief medication (such as acetaminophen), or other drugs as needed. It is essential to take these medications only as directed. Non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen are generally avoided for several 
5. Regular follow-up exams are crucial for monitoring any potential recurrence of cancer. Most patients are scheduled for a follow-up visit within 2-4 weeks post-surgery for suture removal and evaluation of the surgical site. 
6. To reduce scarring, applying sun protection (SPF 30 or higher) to the area is highly recommended. Other options for scar management include steroid creams, laser therapy, dermabrasion, or resurfacing procedures, which can be discussed with the healthcare provider based on individual needs.
