Ear Reconstruction After Mohs Surgery: Repairing Form and Function Following Skin Cancer Removal

Book An Appointment
ear reconstruction after mohs surgery

Losing part of your ear to skin cancer can be devastating. 

Beyond the emotional impact, physical changes to this complex cartilaginous structure can affect not only appearance but also hearing and function. Fortunately, with the right surgical approach, skilled reconstructive techniques can restore the natural contours and symmetry of the ear after skin cancer removal.

Ear reconstruction following Mohs surgery represents a complex process, but also an opportunity. In the hands of experienced reconstructive surgeons, this restorative work aims to rebuild the structural framework of the ear and recreate natural aesthetic form. Utilizing a combination of skin flaps, cartilage grafts, and meticulous layering approaches, post-Mohs ear repair can produce excellent functional and cosmetic outcomes.

Mohs Surgery

Mohs micrographic surgery has become a common technique for removing different skin cancer types on the ears, including basal cell and squamous cell carcinomas. By progressively excising and examining cancerous tissue under a microscope, Mohs surgery aims to remove tumors while conserving as much healthy tissue as possible.

However, the intricate cartilaginous anatomy of the ear means skin cancer removal can create complex defects. The ear’s unique topography—with many ridges, depressions, and a thin covering of skin over cartilage—poses challenges for reconstruction after Mohs surgery.

Depending on cancer size and location, the Mohs procedure may require excising skin, cartilage, or both. This can leave noticeable dents, holes, or malformed areas. In addition to cosmetic concerns over the ear’s appearance, this type of tissue removal can also affect structure and function.

That’s where reconstructive surgery comes in. The goals of ear reconstruction after Mohs surgery include:

  • Restoring natural form and symmetries. Carefully rebuilding the contours and anatomical structure of the ear is a priority. This helps restore a natural, aesthetically-pleasing appearance.
  • Preserving or improving hearing/function. Ensuring the ear canal opening and internal structures are intact helps maintain hearing ability and ear functionality.
  • Protecting long-term ear health. Providing ample skin coverage and blood supply supports healing and prevents future complications like infection or deformation.
  • Factoring in patient expectations. Considerations like lifestyle and priorities help guide reconstructive approaches.

With careful planning and execution, ear reconstruction can successfully meet these goals following skin cancer removal.

Reconstruction Techniques and Modalities Used on the Ear

Ear defects after Mohs surgery can vary considerably depending on:

  • Size - Small, medium, large, or total ear loss
  • Depth - Skin only or involving cartilage
  • Location - Different ear zones like the bowl, lobule, helix

To address this spectrum, plastic and reconstructive surgeons have a range of repair techniques from which to choose:

TechniqueDescriptionAdvantagesDisadvantages
Skin graftsUse skin from behind ear or scalpLess invasive, quickerLess blood supply, need for second site
Local skin flapsRotate nearby skin into defectRobust blood supplyMore complex, longer surgery
Cartilage graftsGraft ear/rib cartilageProvides structureDonor site, shaping challenges
Primary closureSuture wound edges togetherSimple, single siteOnly for smaller defects

The specific approach depends on the characteristics of the Mohs defect and patient factors like age and medical status. In many cases, a combination of modalities is used.

For example, a large defect on the ear's bowl involving loss of cartilage may require a skin flap for coverage along with a structural cartilage graft. Accurately assessing the post-Mohs defect and thoughtfully selecting from available reconstructive techniques is key to success.

Surgical Steps and Considerations for Ear Repair After Mohs

Meticulous surgical planning and execution forms the foundation of ear reconstruction after Mohs surgery. The main procedural steps include:

  • Thorough defect evaluation - The surgeon closely examines the wound to determine size, depth, location, and structures involved. Precise measurements are taken and diagrams made to aid in reconstructive planning.
  • Developing a surgical strategy - Based on the defect analysis, appropriate techniques are selected to restore missing skin and cartilage. This plan is tailored to the patient’s unique situation.
  • Cartilage framework - For larger defects or those with cartilage loss, cartilage grafts from the ear or ribs are strategically placed to provide structural support.
  • Skin/Soft tissue repair - Skin flaps or grafts are positioned to provide ample skin coverage over the cartilage framework. Local skin flaps are commonly used due to their robust blood supply.
  • Layered closure - Deep sutures, followed by subcutaneous, then skin closure helps support the intricate ear anatomy. Drains may be placed to prevent fluid buildup.
  • Dressings & supportive care - A padded dressing protects the ear repair while minimizing pressure. Head dressings help stabilize the ear post-operatively.

Throughout reconstructive ear surgery, maintaining adequate blood supply and venous outflow are crucial elements. Avoiding tension or distortion of the intricate ear structures also helps promote optimal healing.

For larger or complex defects, staging procedures over multiple surgeries may be required. 

Recovery: What to Expect After Ear Reconstruction Surgery

The recovery process after ear reconstruction aims to protect repairs while allowing optimal healing. Here’s an overview of what to expect:

  • Early recovery - The first 1-2 weeks focus on incision care, changing dressings, and monitoring for complications like bleeding or infection. Pain medication and head dressings help provide comfort.
  • Transition phase - At 2-4 weeks, sutures are removed and swelling/bruising continues to improve. Ear micromovements and light activity may be allowed.
  • Maturation stage - From 1-3 months, patients can return to work/school and ease into exercise. The ear regains normal sensations like touch. Final contour refinements may be done.
  • Long-term - After around 3-4 months, most recovery milestones are met, but the ear continues to stabilize over the next year. Patients should watch for issues like receded skin or cartilage warping.

Reconstructive surgeons will closely follow progress during the recovery period through frequent office visits and oversight. Patients play an important role by carefully following post-op protocols and reporting any worrisome symptoms.
