Preoperative Information

Before the Day of Procedure

Please complete and review the following materials in preparation for your upcoming Mohs Surgery appointment in our Dermatology Department.

Medications

Take all of your usual medications including insulin on the day of surgery, unless directed otherwise. If you take any medications with Coumadin or Warfarin, please have your INR lab drawn within 72 hours before your procedure date. You may bring the results to your appointment or fax them to the Dermatology Department at 515-663-4836.

The Night Before Surgery

You may want to wash your hair the night or morning before surgery because you will be asked not to shower for at least 24 hours following surgery.


Day of Procedure

  • On the morning of surgery, wash your face thoroughly and do not apply any makeup. Also, do not wear clothing you must pull over your head as it may be difficult to remove after surgery.
  • You may eat a normal breakfast or lunch on the day of your surgery.
  • Feel free to bring along activities such as books, tablets, etc., or food, snacks, or beverages. We strive to make your visit as pleasant as possible, however, there will be wait times involved due to the nature of the procedure. 

What to Expect During Your Mohs Surgery

During the procedure, the Mohs surgeon removes the visible tumor and a margin of healthy tissue. Then your removed tissue is "mapped" and examined under the microscope for remaining cancer cells. With the Mohs procedure, the surgeon can examine 100 percent of the tissue that surrounds the tumor.


What to Expect After Your Mohs Surgery

After the cancer is removed, the Mohs surgeon repairs the area of skin you have lost. Reconstruction may be performed by simply sewing up the wound, or by using techniques such as skin flaps and grafts. Occasionally, wounds are allowed to heal on their own (without stitches, flaps, or grafts). Your Mohs surgeon will help you choose the reconstruction technique that is best for you.


If you have any questions, please do not hesitate to call our office at 515-663-4892.

Frequently Asked Questions

What is Mohs micrographic surgery?

It is a specialized surgical treatment for skin cancer which can provide the highest cure rate while removing the least amount of surrounding healthy tissue.

What other services are provided by a Mohs surgeon?

Addtional services provided by a Mohs surgeon include, but are not limited to, excisional surgery, scar revisions, melanoma treatment, mole removal and laser therapy.

When is Mohs surgery used?

Mohs surgery is usually recommended for skin cancers that occur on sensitive areas of the body or that have a high likelihood of recurrence.
These include skin cancers that:

  • Are located in cosmetically or functionally important areas such as around the face, scalp and neck. Mohs surgery can be used on other body areas for skin tumors that have a high risk of recurring.
  • Have cells that grow rapidly or deeply.
  • Have recurred after previous treatment.
What are the risks of Mohs surgery?

As with every surgery the risk of complications does exist. Complications associated with Mohs surgery are uncommon, but may occur. When they do occur, they include, but are not limited to:

  • Bleeding-Excessive bleeding under a wound that has been sewn up (sutured) can delay healing.
  • Infection- Rarely, wounds become infected and may require antibiotic treatment.
  • Loss of nerve and muscle function- Uncommonly, the surgery may result in impaired nerve or muscle function. This is often temporary, but may be permanent.
  • Poor healing- In some instances the wound created by the surgery may heal slowly or not as well as anticipated.
  • Swelling- All surgery results in swelling that decreases gradually during healing.
  • Scarring- All techniques to remove skin cancer can cause scarring. With Mohs surgery, the wound that is present after removal of the skin cancer is the smallest possible; this helps minimize scarring.

Mohs Surgery: The Most Effective Treatment for Skin Cancer

Mohs micrographic surgery is the most effective and advanced treatment for skin cancer. It is performed on an outpatient basis using a highly specialized and precise technique that removes the cancer in stages, one tissue layer at a time. This technique allows physicians to precisely identify and remove a tumor while leaving the surrounding healthy tissue intact and unharmed. Mohs surgery offers the highest potential for cure – even if the skin cancer has been previously treated by another method. To ensure that your skin cancer treatment is performed to the highest standards of quality and competency, be sure to choose an American College of Mohs Surgery (ACMS) fellowship-trained Mohs surgeon.
