Post-Operative Care After Mohs Surgery
Mohs micrographic surgery is a specialized procedure, and it is used for treating certain skin cancers, such as basal cell carcinoma and squamous cell carcinoma. Mohs surgery removes cancerous tissue in layers and examines each layer under a microscope during the procedure. It allows for precise removal with the aim of sparing as much healthy tissue as possible.
Who Is Mohs Surgery For?
Mohs surgery is typically performed on individuals diagnosed with high-risk skin cancers, which may be defined by tumor location, size, growth rate, or recurrence after previous treatment. The technique is also appropriate for treating cancers that have recurred or have indistinct borders, as it allows for close examination and targeted removal of affected areas. Although primarily used for basal cell and squamous cell carcinomas, Mohs surgery may be used for other types of cancers.
What Does It Involve?
The procedure is performed under local anesthesia and completed in stages during a single outpatient visit. The surgeon begins by numbing the area and excising the visible tumor, followed by removing a thin margin of surrounding tissue. This tissue is marked to correspond with its orientation on the body for accurate mapping. The removed tissue is processed immediately into microscope slides and analyzed to determine whether any cancer cells remain at the margins.
If cancerous cells are identified in any portion of the examined tissue, the surgeon returns to the patient. They can remove an additional thin layer from the targeted area. This process is repeated as necessary until all margins are clear of cancer cells. Because only tissue where cancer remains is removed, this method helps preserve the greatest amount of healthy skin. Each stage, including examination and preparation of tissue, can require a waiting period of up to an hour. The number of stages needed will vary depending on the size, depth, and complexity of the tumor.
What Does Recovery Entail?
Recovery after Mohs surgery depends on the size and location of the defect, the method of closure, and patient-specific factors. Swelling around the surgical area is common, especially for procedures on the face or areas close to the eyes. These symptoms often peak within the first two days after surgery. Ice application as directed can help reduce swelling. Mild discomfort can often be managed with over-the-counter pain relievers; severe pain is unusual and should prompt medical contact.
Post-operative wound care is directed by the surgeon and usually includes keeping the wound clean and protected with ointment and a bandage. Wound care helps promote faster healing and may minimize the development of scabs or crusts. These are sometimes associated with delayed healing or increased scarring. It is recommended to keep the area bandaged for several days as directed.
Consult With a Dermatologist
Patients scheduled for or recovering from Mohs surgery benefit from regular communication with their dermatologist or surgeon, who can tailor postoperative care to individual health needs and the specifics of their procedure. Following personalized advice on wound management, activity level, and follow-up appointments helps support healing and long-term skin health.
