Microtia / Total Ear Reconstruction | Long-term appearance and maintenance

Microtia ranges from minor deformity to near absence of the ear, and reconstruction must create both a supportive framework and suitable skin cover. The normal auricle is complex, so results depend on framework design, tissue quality, surgical judgment and experience. One source notes reconstructed ears often lack projection, definition and the post-auricular sulcus, while another reports a polyethylene construct with excellent projection and form at 14 months after a cartilage construct lacked those features. Complications such as skin vascular compromise, infection, cartilage resorption or wire extrusion can also affect detail. All aesthetic and anatomical details depend on the relief of the grafted framework.

Microtia reconstruction usually uses rib cartilage carved into an auricular framework, then covered by local skin. The reconstructed ear may be rigid, thick and less finely defined than a normal ear because skin and cartilage are less ideal. Growth observations suggest most frameworks grow and may slightly overgrow, while shrinkage or loss of detail is uncommon. Cartilage resorption can occur, especially with infection or poor blood supply, and may alter shape or projection. Reconstruction is often staged, with framework placement then elevation; complications such as skin vascular compromise, infection, wire extrusion or cartilage resorption can affect final contour. Because each patient's cartilage, skin thickness and healing differ, the final ear may not match the opposite ear exactly.

With a bone-anchored system, the pillars are cleaned daily with water, soap and a cotton swab. If acute inflammation occurs, topical antibiotics such as fusidic acid may be used for a few days; chronic granulating tissue may be treated with topical steroids for three weeks. The prosthesis is removed at night and for bathing or swimming, and a helmet helps protect it during physical activity. Older adhesive prostheses can detach spontaneously. In one 16-year review, 75% of patients had skin problems such as granulation tissue or local infection requiring antibiotics, and satisfaction was disappointing. The prosthesis is custom-made and fitted onto the abutments after osseointegration. Daily cleaning helps prevent chronic inflammation around the pillars.

Microtia reconstruction commonly uses a rib cartilage framework placed under local mastoid soft tissue, but the reconstructed ear often lacks projection, definition and a post-auricular sulcus. Symmetry depends on precise framework position and projection; the normal ear may also appear prominent. Secondary corrections can range from a direct cutaneous approach for a cartilaginous irregularity to a V-Y skin plasty to deepen a retracted sulcus. In one reported strategy, if framework projection is at least 80% of the normal ear, second-stage elevation may not be insisted upon; if less, elevation is considered and the patient decides. Contralateral otoplasty may also be discussed when the opposite ear hinders symmetry.

After the second stage, skin grafts in the retro-auricular sulcus can contract and reduce sulcus depth or ear projection. An elastomer ear splint is fitted at about two weeks to counteract those contractile forces. If a small area of skin graft necrosis occurs, the necrotic skin may be debrided and treated with wet-to-dry gauze twice daily, with expectation that the area contracts and heals. For a larger area of skin loss, additional skin may allow more rapid healing and help prevent significant contracture and loss of ear definition. If cartilage becomes exposed, a temporal muscle flap with skin grafting may be used. Previous scars can also compromise skin flap blood supply.

Microtia is a congenital ear deformity, often associated with aural atresia and conductive hearing loss on the affected side. For severe microtia, reconstruction may be performed in two surgical stages: first creating a new auricular framework and cutaneous covering, then elevating and refining the ear. The described technique aims for aesthetic detail, facial symmetry and regular sensibility of the reconstructed ear. Because each patient has peculiar anatomy, the surgeon must consider individual characteristics carefully. The cited source supports regular sensibility, but does not describe how it compares with a normal ear. Complications can include skin vascular compromise, infection, cartilage resorption or wire extrusion. Individual suitability, expected sensation and risks are discussed during consultation.

Reconstructed microtia ears contain a cartilage framework under thin skin, so a routine piercing can be difficult and may risk infection or damage. A piercing can sometimes be retained during first-stage reconstruction if its tract lies suitably relative to the future lobule, and the surgeon must clean the tract carefully. After reconstruction, piercing may be done by reducing the framework and placing the piercing below the cartilage, or by creating a hole through the cartilage. These are surgical decisions, not salon procedures. When performed after reconstruction, the surgeon marks the ideal position, uses sterile earrings left for three to four weeks, and applies antibiotic ointment until the skin lines the tract.

Pressure can distort the reconstructed ear, affect skin blood supply and expose the underlying cartilage framework. For this reason, pressure dressings are usually not recommended, and patients should avoid sleeping on the reconstructed side. Glasses should be avoided; if essential, remove the earpiece on that side. After bilateral reconstruction, both ears need pressure protection during sleep for the first two weeks, which is one reason the two sides are not operated together. Sun protection with a wide-brimmed hat for several months and gentle cleaning after one month also support healing. Repeated pressure from helmets or headgear should be avoided while healing, and the surgeon can advise when sports and normal activities are safe.

Microtia often occurs with aural atresia, so the affected side usually has conductive hearing loss; hearing difficulties may become more noticeable as social and school demands grow. Parents may see little difference early, but effects can show later. Hearing aids, bone-conduction aids or implantable devices may be considered, and the unaffected ear should be monitored closely. External ear reconstruction should precede middle-ear surgery, and many high-volume centres avoid ear-canal surgery first because of long-term problems such as narrowing, discharge or cholesteatoma. In bilateral cases, both ears are affected and early hearing support may be needed. The hearing team decides timing and device choice based on age, anatomy and hearing tests.

Prosthetic ears can look very real and be worn with adhesive or surgically implanted anchors; the anchor procedure is minor with minimal recovery. They suit children for whom reconstruction was not possible or unsuccessful. Some people dislike a detachable prosthesis, others have skin sensitivity to medical-grade adhesives, and implanted anchors can raise skin infection risk. Implant-retained prostheses remain an option even after failed reconstruction, but one source prefers postponing implant surgery until adolescents can judge risks themselves. Most reconstructive surgeons prefer autologous reconstruction as the treatment of choice for children with microtia. Prosthetics also need periodic replacement, and adhesive-retained prostheses should not be considered a trial for implant-retained ones.
