Why MOHS Surgery is Used to Eyelid Skin Cancers.
Meet
Dr Mopi Lenake, ophthalmologist and
oculoplastic surgeon. She is one of the reconstructive surgeons who works closely with Dr Johann de Wet in the Somerset West branch of the
Skinmatters Mohs and Reconstructive Unit.
“The goals of eyelid reconstruction after skin cancer excision include restoring eyelid structure and function while attaining acceptable aesthetic results. Mohs surgery achieves high cure rates while preserving healthy tissue, making it a useful technique for removing skin cancers around the eyelids where small amounts of tissue may involve important structures that affect the normal function of the eyelids.”
Mohs surgery is particularly helpful in removing
basal cell carcinoma and squamous cell carcinoma around the eyelids. Recurrent tumours and cancers involving the medial canthus can be especially challenging and may benefit from Mohs surgery due to its precise margin control.
Another advantage of working with a Mohs surgeon is that the excision and reconstruction can be planned as a coordinated procedure. This approach allows the
reconstructive surgeon to proceed with confidence once all cancerous tissue has been removed.
Removal of Eyelid Skin Cancer
Mohs surgery is an effective treatment for eyelid cancers for several reasons.
The eyelids are a delicate and complex area of the face that require precision and expertise. Mohs surgery allows for the preservation of healthy tissue while removing cancerous tissue with maximum precision.
The eyelids also have high cosmetic and functional importance. Mohs surgery removes only the cancerous tissue and preserves as much healthy tissue as possible, helping to maintain the natural appearance and function of the eyelid.
In addition, eyelid skin cancers have a risk of recurrence. Mohs surgery allows the entire surgical margin to be examined during the procedure, helping to ensure that all cancer cells have been removed before reconstruction is performed.
Overall, Mohs surgery is a highly effective treatment for eyelid skin cancer because of its precision, tissue preservation and high cure rates.
What Is Eyelid Skin Cancer?
Eyelid skin cancer, also known as eyelid carcinoma, is a type of cancer that develops on the skin of the eyelids. It is most commonly caused by excessive exposure to ultraviolet (UV) radiation from the sun over an extended period.
UV radiation can damage DNA within skin cells, leading to uncontrolled growth of abnormal cells and the development of cancer.
Types of Eyelid Skin Cancer
There are different types of skin cancer that can occur on the eyelids.
Basal Cell Carcinoma (BCC):
BCC is the most common type of eyelid skin cancer. It often appears as a small, raised or pearly bump with visible blood vessels. It may ulcerate or crust over but is typically slow growing and rarely spreads to other parts of the body.
Squamous Cell Carcinoma (SCC):
SCC is less common than BCC but is generally more aggressive. It may present as a scaly red patch or rapidly growing nodule and can spread to regional lymph nodes if left untreated.
Melanoma:
Melanoma is the least common but most serious form of eyelid skin cancer. It often appears as a dark or irregularly shaped lesion and has a higher risk of spreading to other parts of the body.
Symptoms of Eyelid Skin Cancer
Eyelid skin cancer can cause symptoms such as itching, pain, tenderness and visible changes in eyelid appearance.
Any unusual growth, sore, lump or change affecting the eyelid should be assessed by a medical professional. An ophthalmologist or dermatologist may perform a thorough examination and biopsy to determine whether a lesion is cancerous.
Treatment for Eyelid Skin Cancer
Treatment depends on the type, size and stage of the tumour.
Surgical excision is the primary treatment for most eyelid skin cancers. In selected cases, Mohs micrographic surgery may be recommended because it combines complete margin assessment with maximum preservation of healthy tissue.
Early detection and treatment offer the best chance of successful outcomes while helping to minimise complications. Patients should also take steps to protect their skin from excessive sun exposure through appropriate sun protection measures.
Reconstruction After Eyelid Skin Cancer Surgery
Following the removal of eyelid skin cancer, reconstruction may be required to restore both function and appearance. Mohs surgery provides the advantage of confirming complete tumour removal before reconstruction is undertaken.
The Mohs and Reconstructive Unit works collaboratively with reconstructive and oculoplastic surgeons to achieve the best possible functional and cosmetic outcomes for patients undergoing eyelid skin cancer surgery.
