Treatment Options for Skin Cancer on Ear
Treatment Options for Skin Cancer on Ear In general, ear cancer is defined as the uncontrolled development and growth of cancer cells in the ear. Ear cancer is comparatively the least common of all types of cancers. In general, cancer in the ear develops as skin cancer in or around the outer part of the ear. Cancer cells can develop in one of three parts of the outer ear constituting the visible Pinna Chartreux (auricle), the ear canal and the outer layer of the eardrum (Tytipanique membrane).
Primary treatment options for external ear cancer
The choices of corrective measures include surgery or radiotherapy, or both. These corrective measures almost cure cancers in the outer part of the ear. The category and extent of the surgery to be performed are based on the stage of cancer. The most common types of surgery are listed below:
- Micrographic Surgery of the Mohs
- Great local excision
- Excisional biopsy
- lymph node dissection
Mohs Micrographic Surgery
Mohs Micrographic Surgery is a procedure in which thin layers of cancer-containing skin are progressively removed with the surrounding thin layer of healthy tissues. The thin layer of cancerous skin, which has been removed by Mohs surgery, is subjected to sectioning, freezing, staining, and mapping in detail, then it is completely examined under a microscope.
If the cancer is still found in the inner or outer layer of this surrounding thin tissue layer, the surgeon removes the patient’s indicated cancer tissue through the Mohs procedure. This procedure is repeated on all sites that still contain cancer cells until no other cancerous cell is under a microscope.
Great local excision
In addition to the initial biopsy, a large local excision is used in melanomas (malignant tumor in skin cancer) that tend to reproduce.
The procedure generally is 1 to 2 cm of healthy skin around the location of the melanoma; Nevertheless, the variation of this margin depends on factors such as the impact of the depth of the tumor and its extent of propagation in the dermis and the layers of the hypodermis of the skin. The closure of large local excision with stitches is often performed on smaller lesions, but skin grafts or skin flaps may be used on larger lesions.
In a biopsy approach to excision, the surgeon uses a lancet to completely excise the area affected by the tumor and the margin of excision of healthy skin around it. The surgical wound around the tumor site can be sewn.
The specimen of tissue removed is observed under a microscope to ensure that all tumor cells have been excised. This procedure can be repeated later until no other cancer cell is examined on a skin specimen under a microscope. With this approach, the primary cure rate of primary cancers is approximately 92%.
Lymph node surgery
In the ganglionic biopsy, the ganglionic tissue is excised and examined under a microscope to determine the symptoms of a tumor or other infection. Lymph nodes are listed under the human immune system. Lymph nodes are found in the body, but swollen lymph glands in the neck, armpits and groin area are not easily identifiable.
Enlargement of the lymph nodes usually refers to the symptom of cancer or other infections. No specific care is required for most lymph nodes in cases where they become enlarged due to local infection or trauma.
Otoplasty or ear reconstruction surgery
The reconstruction of the ear remains one of the most difficult areas of plastic surgery. The first step in reconstructive surgery is to develop a skin pocket at the place of the ear by redirecting the available tissue and thinning the skin to match the cosmetics of the skin of the adjacent ear.
Three small pieces of rib cartilage are harvested. The rib cartilage is carved and wired with a stainless steel fine wire to make a detailed frame that looks like an ear. The entire frame is then inserted into a pocket. A gentle aspiration can be achievable by melting the skin and the structure of the ear together.

The second step involves positioning the new ear in such a way that it normally projects from the head like a normal ear. The ear is lifted from its bed and the positioning is held by another piece of cartilage that is attached behind the ear. To end the process, a layer of tissue and skin graft are taken and placed on the uncovered cartilage.
In radiotherapy, very intensive rays of energy (radiation) are used to treat cancer. To begin with radiation treatment, the patient should consult the radiologist who designs the treatment schedule, which can last between 4 and 6 weeks.
If cancer on the outer part of the ear or Pinna is low, then radiation therapy is enough to kill cancer cells. It is also possible to have post-operative radiotherapy in situations where the doctor is unable to dissect a clear margin around cancer. This reduces the risk of cancer recurrence after the tumor has been removed by surgery.
