Ear Surgery (Otoplasty): Correction of Protruding or Misshapen Ears

By: Senior Surgeon — Educational Information

Introduction

Otoplasty (ear surgery) is a widely performed procedure to correct protruding ears, prominent ear deformities, and a variety of congenital or acquired ear shape abnormalities. As a senior surgeon experienced in both cosmetic and reconstructive procedures, I view otoplasty as a surgery that blends precise cartilage work, careful soft‑tissue handling, and thoughtful aesthetic judgment. The goal is to create ears that are symmetric, proportional to the patient’s face, and that preserve natural contours while minimizing visible scarring and functional compromise.

This article provides a comprehensive, practical overview of indications, ear anatomy, patient evaluation, surgical techniques, anesthesia, postoperative care, complications and their management, patient selection, and long‑term outcomes.

Why patients seek otoplasty

Cosmetic concerns: conspicuously protruding ears, large conchal bowls, deformities of the antihelix, or ears that appear “too large” relative to the face.
Psychosocial impact: children and adults with prominent ears often experience teasing or self‑consciousness; correction can improve confidence and social functioning.
Congenital deformities: lop ear, cup ear, Stahl’s ear, cryptotia, concha hypertrophy, and helical rim abnormalities.
Traumatic or post‑surgical deformities: ear injuries and prior surgical results that require revision.

Ear anatomy and aesthetic principles

Successful otoplasty requires intimate knowledge of auricular anatomy and how subtle changes affect perceived prominence and symmetry.

Key anatomic landmarks

Helix: the outer rim of the ear; defines the overall silhouette.
Antihelix: the curved ridge parallel to the helix; deficiency or underdevelopment of the antihelical fold often contributes to protrusion.
Concha (conchal bowl): deep cavity adjacent to the ear canal; conchal hypertrophy pushes the ear laterally.
Lobule (earlobe): composed of soft tissue without cartilage; its size and position contribute to overall ear shape.
Scapha and triangular fossa: intermediate depressions that add contour.
Cranioauricular angle: the angle between the ear and the skull; normal adult angle ranges roughly from 20°–30° laterally — increased angles correspond to protrusion.

Aesthetic principles

Symmetry: ears rarely match perfectly; aim for harmonious balance rather than absolute identity.
Proportion: scale of the ear relative to facial features and head size is important — overcorrection to achieve symmetry can look unnatural.
Natural contours: recreate a soft, natural antihelical fold and gradual conchal slope.
Incision placement: hidden scars behind the ear (postauricular) or within natural creases give optimal concealment.

Preoperative evaluation and planning

History

Age, onset (congenital vs acquired), prior ear surgery or trauma.
Psychosocial context — for children, ask about school teasing and family expectations.
Medical history: bleeding disorders, smoking, medications (anticoagulants), and conditions that impair healing (diabetes, autoimmune disease).

Physical examination

Measure cranioauricular angle and compare both sides.
Assess cartilage thickness and pliability — thin cartilages are easier to reshape but can be overcorrected; thick cartilage needs more robust scoring or suturing.
Evaluate the antihelix, conchal depth, lobule, and skin quality.
Look for associated craniofacial asymmetries or conditions (microtia, hemifacial microsomia) that may affect the surgical plan.

Photographic documentation

Standardized photos: frontal, oblique, lateral (both sides), posterior, and top view. These help with planning and postoperative comparison.

Timing: Surgery in children vs adults

Otoplasty can be performed safely in children once the cartilage has achieved sufficient strength — commonly around age 5–6, when ear growth is near adult size.
In adults, otoplasty is equally effective with similar principles of technique, though cartilage stiffness may be greater.

Surgical goals and technique selection

Otoplasty techniques are chosen based on the primary deformity:

Underdeveloped antihelix (most common): techniques that create or enhance the antihelical fold (e.g., Mustardé sutures for fold creation) are used.
Conchal hypertrophy: conchal setback or conchal resection and suturing to decrease conchal prominence.
Lobule deformity: earlobe reshaping or setback by excision and advancement.
Combined deformities: often require a combination of cartilage scoring, suturing, and limited cartilage resection.

No single technique fits every ear. The two broad technical approaches are cartilage‑preserving (suture) and cartilage‑modifying (scoring/resection), and many modern operations combine both.

Common operative techniques

Posterior (postauricular) approach

Incisions are typically placed in the posterior sulcus (behind the ear) where scars are concealed.
A posterior skin flap is elevated to expose the perichondrium and cartilage.

Mustardé (mattress) sutures for antihelical fold creation

Permanent or long‑lasting sutures placed through the cartilage to fold and set the antihelix.
Advantage: cartilage preserved, lower risk of contour irregularities if placed carefully.
Suited for pliable cartilage and mild–moderate antihelical deficiency.

Furnas (conchal setback) sutures

Sutures placed from the conchal cartilage to the mastoid periosteum to reduce the cranioauricular angle and move the ear closer to the head.
Useful for conchal hypertrophy causing overall protrusion.

Cartilage scoring and resection

For stiffer cartilage or when stronger reshaping is needed, anterior scoring (weakening the cartilage) or partial resection of conchal cartilage is performed.
Scoring relaxes the cartilage on one side, allowing it to bend and hold a new shape. Careful technique prevents notching or sharp deformities.

Lobule modification

Direct excision or reshaping of the lobule (especially in “stuck‑on” or prominent lobule variants) with careful closure to minimize visible scars.

Combined techniques

Many ears require antihelix formation plus conchal setback — combining Mustardé sutures with Furnas sutures and selective cartilage scoring achieves a balanced result.

Incision closure and dressings

Posterior skin closed with fine sutures; a head dressing or ear splint is placed to maintain position and reduce swelling. Dressings are usually removed after 24–48 hours and replaced with a light headband worn for several weeks, especially during sleep.

Anesthesia and operative setting

Otoplasty may be performed under local anesthesia with sedation for cooperative adults and older children.
General anesthesia is often used in young children for safety and comfort.
The choice depends on patient age, anxiety level, and combined procedures.

Postoperative care and recovery

Immediate postoperative period

Head dressing or ear splint is applied to prevent hematoma and protect the ears. Pain is typically mild to moderate and controlled with oral analgesics.
Antibiotics may be administered perioperatively; some surgeons give short postoperative courses.

First week

Dressings are changed and sutures are often removed between 5–10 days depending on technique. Swelling and bruising peak within the first 48–72 hours and improve thereafter.
Patients are advised to avoid direct pressure on the ears and to sleep with the head elevated.

Weeks 2–6

Light activities are resumed within days; more strenuous activity and contact sports should be avoided for 4–6 weeks to prevent trauma and hemorrhage.
The ears generally settle into their new shape over several weeks; residual swelling slowly resolves.

Long‑term outcomes

Most patients achieve stable, durable results with improved cranioauricular angles and natural contours. Scar lines behind the ear typically fade to an inconspicuous line.

Complications and their management

Although otoplasty is generally safe, complications can occur. Prevention starts with appropriate patient selection and meticulous technique.

Hematoma

A postauricular hematoma may require prompt drainage to avoid cartilage necrosis and infection. Meticulous intraoperative hemostasis and secure dressings help prevent this.

Infection

Relatively uncommon but can affect cartilage (chondritis); early recognition and appropriate antibiotics (and drainage when necessary) are essential.

Overcorrection or undercorrection

Overly aggressive setback or fold creation can produce ears that look pinned back or unnatural. Undercorrection may leave residual prominence. Minor asymmetries can sometimes be corrected with revision surgery after healing.

Scarring and contour irregularities

Visible contour irregularities (notching, step-offs) can result from mishandled cartilage scoring or uneven sutures. Revision may involve scar release, additional suturing, or grafting.

Suture extrusion or late suture visibility

Permanent sutures may become palpable or extrude; they can often be removed and replaced or revised.

Sensory changes

Temporary numbness around the ear is common and usually resolves. Persistent numbness is unusual.

Keloids or hypertrophic scarring

Patients with history of poor scarring need counseling; treatment options include steroid injections, silicone therapy, or revision.

Special considerations

Pediatric psychosocial context

For children, family support and realistic expectations are crucial. Psychological benefits can be substantial when surgery addresses ongoing bullying or psychosocial stress.

Revision otoplasty

Revision operations are more complex due to scar tissue, altered cartilage, and possible loss of tissue. A staged approach, cartilage grafting, or composite techniques may be required.

Ethnic and gender considerations

Aesthetic ideals vary: male ears may be set with slightly greater projection than female ears in some aesthetic philosophies. Respect for ethnic characteristics and patient preference is essential.

Patient selection and counseling

Ideal candidates are healthy, with realistic expectations and clear reasons for surgery. Counsel patients on risks, recovery, and realistic outcomes including possible need for revision. Review preoperative photos and show examples of results for similar ear types.

Longevity and maintenance of results

Otoplasty results are typically stable for life once growth is complete. Trauma or later changes in cartilage over decades can alter appearance, but most patients enjoy long‑term satisfaction.

Choosing a surgeon

Seek a board‑certified plastic surgeon or otolaryngologist/ facial plastic surgeon with specific experience in otoplasty. Examine before‑and‑after photos and ask about complication rates and revision policies.

Conclusion

Otoplasty is a reliable, often life‑changing procedure for correcting protruding or misshapen ears. The best outcomes come from individualized planning, respect for auricular anatomy, conservative cartilage manipulation when appropriate, and clear patient counseling. Whether performed in children to address psychosocial concerns or in adults for aesthetic refinement, otoplasty—when done by an experienced surgeon—produces natural, enduring results with relatively low complication rates.
