Micrographic surgery
Micrographic Surgery is a precise surgical technique used primarily in the treatment of skin cancers, including basal cell carcinoma and squamous cell carcinoma. It is known for its high cure rate and conservation of healthy tissue.
Overview
Micrographic surgery, often referred to as Mohs surgery, involves the systematic removal and microscopic analysis of thin layers of cancer-containing skin until only cancer-free tissue remains.
Technique
The technique includes several steps:
- Tissue Removal: The visible portion of the tumor is removed, along with a thin layer of surrounding tissue.
- Microscopic Examination: The excised tissue is immediately examined under a microscope.
- Iterative Process: Additional layers of tissue are removed and examined until no cancer cells are detected.
Applications
Micrographic surgery is primarily used for:
- Treating skin cancers, especially in cosmetically and functionally important areas like the face.
- Removing tumors that have recurred after previous treatment or that have edges that are hard to define.
Benefits
The advantages of micrographic surgery include:
- High Cure Rate: It offers the highest cure rate for basal cell carcinoma and squamous cell carcinoma.
- Tissue Conservation: Maximizes the preservation of healthy tissue.
- Reduced Scarring: Leads to less scarring compared to other methods.
Preoperative and Postoperative Care
Patients undergoing micrographic surgery need to follow specific preoperative and postoperative instructions to ensure optimal outcomes.
Training and Certification
Surgeons performing this technique undergo specialized training in dermatology and micrographic surgery.
Challenges and Considerations
While highly effective, micrographic surgery requires significant expertise and can be time-consuming. Patient selection and tumor characteristics are critical for optimal outcomes.
