Prominent ears (commonly called bat ears) is the most frequent congenital ear shape variation, affecting roughly 5 percent of the population. The condition is defined by an auriculocephalic angle greater than 25 degrees, an underdeveloped antihelical fold, or an overdeveloped conchal bowl that projects the ear away from the skull. Otoplasty corrects all three components in a single 1.5–2 hour procedure under local or general anaesthesia.
Key Facts
Why ears stick out: the anatomy
Three anatomical features determine ear projection. First, the antihelical fold — the Y-shaped ridge inside the ear — may fail to fold during fetal development, leaving the upper third of the ear flat against air rather than curling backward. Second, the conchal bowl (the deep cup-shaped cavity surrounding the ear canal) may be enlarged or angled outward, pushing the entire ear forward. Third, the cartilage stiffness varies by patient — softer cartilage tends to recover better post-operatively while denser cartilage requires more aggressive scoring or suturing.
A typical prominent ear shows one or two of these features. Severe cases show all three. Treatment must address the specific components present, not apply a one-size-fits-all technique.
Functional vs cosmetic impact
Prominent ears are not a medical disease — hearing, balance, and ear health are unaffected. The impact is psychosocial: studies show children with prominent ears experience teasing at school in 50–70 percent of cases, and adults often develop concealment behaviours such as growing long hair or avoiding tied-up hairstyles. Surgical correction has been shown in multiple peer-reviewed studies to improve self-esteem scores, particularly in patients aged 8–18.
When to consider surgery
Otoplasty becomes feasible once ear cartilage reaches near-adult firmness, generally around age 5 to 6. Earlier intervention (newborn ear moulding with thermoplastic splints) can reshape soft neonatal cartilage in the first 6–8 weeks of life but cannot be performed afterwards. From age 6 through adulthood, otoplasty produces equivalent results — there is no upper age limit, and Dr. Erdal regularly operates on patients in their 50s and 60s.
Techniques used for prominent ears
For prominent ears, Dr. Erdal favours cartilage-sparing techniques that reshape the ear with permanent sutures rather than cutting the cartilage. The two cornerstones are Mustardé sutures to create or strengthen the antihelical fold, and Furnas sutures to set back an over-projected conchal bowl. Combined, these techniques produce natural-looking results without sharp edges or unnatural contours.
In selected cases — particularly young patients with soft cartilage — an incisionless approach using percutaneous sutures can be considered, though it is suitable for milder deformities and carries a higher recurrence risk than open techniques.
What results look like
The goal of modern otoplasty is correction, not over-correction. A natural result preserves the helical rim contour, leaves visible antihelical detail, and shows symmetry between the two ears without identical mirroring (a small natural asymmetry is preserved). The post-operative auriculocephalic angle should sit between 17 and 21 degrees — closer than that risks the "pinned-back" appearance seen in older techniques.
Frequently Asked Questions
How long do otoplasty results last?
When performed with cartilage-sparing techniques and permanent sutures, otoplasty results are lifelong in over 95 percent of cases. The cartilage retains its new shape because the sutures maintain tension during the early healing period, after which scar tissue stabilises the position permanently.
Will the ears ever 'pop back'?
Recurrence — where one or both ears begin to project again — occurs in less than 5 percent of cases with modern techniques. Most recurrences happen in the first six months and can be revised with a minor procedure. After one year of stable positioning, late recurrence is rare.
Is the procedure painful?
Otoplasty is performed under local or general anaesthesia, so the surgery itself is painless. The first 48 hours afterwards involve moderate pressure and tightness rather than sharp pain, controlled with standard oral analgesics. Most patients describe discomfort as 3–4 out of 10.
Can both ears be different shapes?
Yes — asymmetric prominent ears (one more projected than the other) are common. The surgical plan adjusts suture placement and tension to bring both ears into symmetry, while preserving the natural minor asymmetry that exists in all faces.
What is the minimum age?
Most surgeons recommend waiting until ear growth is largely complete, which happens around age 5 to 6. By this age the ear has reached 85–90 percent of adult size. Surgery before this risks affecting future growth and producing distortion as the ear continues to develop.
How visible will scars be?
Scars sit in the natural crease behind the ear and are not visible from the front, side, or normal viewing angles. Even on close inspection from behind, the scar usually fades to a thin pale line within 6–12 months and becomes very difficult to detect.
