Microtia: why you have to wait until eight (and what to do meanwhile)

Microtia is a congenital malformation in which the ear does not develop fully. Families arrive at the consultation with many questions and almost always with two things mixed together that are worth separating from day one.

Shape and hearing are separate problems

Reconstruction of the ear addresses the shape. Hearing depends on the middle and inner ear and is assessed by ENT, who decides whether hearing surgery, a bone-anchored aid or neither is appropriate.

They are different specialists and different timetables. Reconstructing the ear does not improve hearing, and treating the hearing does not change the appearance.

One fact reassures many parents: in most cases of unilateral microtia the other ear is normal and language development proceeds without problems. What is worth having is an early hearing assessment, in the first months, so you know where you stand.

Why the wait until eight or ten

Reconstruction is done in stages and with cartilage from the child's own ribs, carved into the shape of an ear and placed under the skin.

That is why the timing is not set by the family's anxiety but by the size of cartilage available: before eight to ten years there is not enough rib to build an adult-sized ear. It is not an administrative rule or a preference: it is a physical limit.

Operating earlier means building a small ear that the other side will outgrow. The wait is not excessive caution: it is what keeps the result good at twenty.

What to do during those years

It is a long and difficult wait, especially once the child starts school, and it deserves support. What can be done:

• Address the hearing first, on its own timetable, which does not depend on the ear surgery.
• Talk about it at home naturally and with words the child can use at school. Having an explanation of their own, simple and theirs, changes how they answer other children's questions.
• Tell the school, especially if there is hearing loss on that side: where they sit in the classroom matters.
• Protect the skin of the area. This is technical and it has consequences: the skin that will cover the new ear must arrive intact, without scars or previous procedures that compromise it. Do not let anyone do anything there without checking first.
• Come to a consultation before surgical age, even if nothing is going to be done yet. It allows planning and gives the family calm answers.

What the surgery is like

It is done in stages, usually from eight or ten years of age. Each stage takes three to five hours, under general anaesthesia, with two or three nights in hospital. The chest, where the cartilage is taken from, is sore for the first days, and that is the part that most surprises families.

What is not promised

An ear identical to the other side is not promised: what is built is a natural-looking, recognisable, well-proportioned ear, with differences of detail visible close up. And hearing is not promised: reconstruction addresses the shape, not the ear.

That said, the real goal is a different one and it is almost always met: that the child can wear their hair however they like, wear glasses, and stop explaining themselves.
