Otoplasty (Ear Reshaping)

Overview

Otoplasty is the surgical correction of auricular (ear) deformities — most commonly prominent ears (protruding ears) resulting from an underdeveloped or absent antihelix fold, conchal excess, or a combination of both. It is one of the few facial surgical procedures performed with equal frequency in children (age 5–12, when the ear cartilage has reached 85–90% of adult size) and adults. The posterior auricular scar is concealed within the natural sulcus behind the ear and is rarely visible.

Auricular prominence is an entirely structural problem. The ear protrudes because one or more anatomical components — the antihelix, the conchal bowl, or the lobule — are in an incorrect spatial relationship to the mastoid bone and the lateral temporal surface. Correction requires identifying which anatomical component is responsible for the prominence and addressing it specifically with the correct technique.

Anatomy: Why Ears Protrude

The auricle has a characteristic three-dimensional cartilaginous architecture with specific landmarks: the helix (outer rim), antihelix (inner curved ridge), scapha (groove between helix and antihelix), conchal bowl (the central cup), and lobule (the non-cartilaginous inferior portion). The natural auricular position sits 1–2 cm from the mastoid, with the helical rim 15–20 mm from the mastoid in adults and a cephaloauricular angle (the angle between the ear and the head surface) of 20–35°.

Prominent ears result from three possible anatomical abnormalities, alone or in combination:

• Antihelix underdevelopment: The antihelix fails to form its characteristic Y-shaped fold, leaving the upper helix without adequate posterior folding — the most common cause, responsible for the "shell ear" appearance.
• Conchal excess: The conchal bowl is abnormally deep or protrudes excessively, pushing the entire ear away from the mastoid. Conchal excess with a well-formed antihelix produces a different prominence pattern — the ear angles away from the head at the base rather than lacking its fold.
• Combined antihelix and conchal abnormality: The most common clinical presentation.

Surgical Techniques

Mustardé Suture Technique (Antihelix Reconstruction)

Permanent mattress sutures (typically non-absorbable nylon or mersilene) are placed through the auricular cartilage via the posterior incision, folding the underdeveloped antihelix into its correct anatomical position. The number and placement of sutures is determined by the height and shape of antihelix correction required. The Mustardé technique is the standard approach for antihelix-predominant prominence.

Furnas Conchomastoid Sutures (Conchal Setback)

Permanent sutures are passed between the posterior surface of the conchal cartilage and the mastoid periosteum, drawing the conchal bowl posteriorly to reduce the auriculocephalic angle. This technique specifically addresses conchal excess. Over-tightening of conchomastoid sutures produces the "telephone ear" deformity — excessive setback of the mid-ear while the upper pole and lobule remain prominent.

Cartilage Scoring

The anterior or posterior cartilage surface is scored (abraded or partially incised) to weaken its spring force and allow permanent sutures to hold the fold with less tension and reduced suture breakage risk. Anterior scoring has largely been replaced by posterior scoring techniques to avoid anterior surface irregularities.

Recovery Timeline

• Days 1–7: Head bandage maintaining ear position. Discomfort managed with oral analgesia. No contact sport or activities risking head trauma.
• Days 7–10: Bandage removal. Suture removal. Ears reveal corrected position. Bruising and minor swelling remain.
• Weeks 2–6: Soft headband worn at night only — protecting suture positions during sleep from inadvertent bending forces. Return to normal activity (except contact sport) at 2 weeks.
• Month 3+: Final position confirmed as fibrous tissue reinforces the suture-maintained fold. Contact sport cleared at 6 weeks.

Cost in the United States

Bilateral otoplasty ranges from $4,000–$8,000 in the United States, comprising surgeon's fee ($2,500–$5,500), anaesthesia, and facility. Adult cases are performed under local anaesthesia with sedation; paediatric cases under general anaesthesia, adding modest additional cost.

Risks and Contraindications

• Recurrence: Suture failure or gradual suture cutting through cartilage can allow partial or complete return of prominence — reported in 5–10% of cases at long-term follow-up. Re-operation corrects recurrence.
• Haematoma: Auricular haematoma is a surgical emergency — prompt drainage is required to prevent avascular necrosis of the cartilage and the resulting cauliflower ear deformity.
• Telephone ear deformity: Overcorrection of the mid-ear conchal setback while the superior and inferior poles remain prominent. Results from over-tightening of conchomastoid sutures. Correction requires suture release and revision.
• Asymmetry: Minor bilateral asymmetry is expected — the goal is acceptably symmetric ears, not geometric equality. Significant asymmetry may require revision.
• Posterior auricular scar: Hypertrophic or keloidal scarring risk in susceptible patients — discussed pre-operatively with a history review.
