Microtia Overview

  • Low-set hairline very common

  • /> The Microtia-Congenital Ear Deformity Institute has evaluated thousands of children born with microtia and atresia. Dr. Bonilla has dedicated his practice exclusively to children born with microtia and atresia. He has evaluated and surgically reconstructed microtic ears on children from all over the world.

    Dr. Bonilla is a strong believer in using our own natural cartilage for ear reconstruction instead of a manufactured product.

    Incidence and possible causes of Microtia

    Microtia occurs more commonly in ills and on the right side (unilateral) . Approximately 10% may occur on both sides (bilateral).

    Microtia usually occurs as an isolated deformity although it can present itself as part of a spectrum of other deformities, either minor or major such as hemifacial microsomia, Goldenhar Syndrome and Treacher-Collins syndrome. Most patients with the most severe form of microtia also lack an external auditory channel, also known as "atresia".

    Children born with bilateral microtia (both sides affected) are managed differently than those with unilateral (one-sided) microtia.

    Luckily, children with unilateral microtia have the other normal side to hear good, crisp , Clean sounds. Children with bilateral microtia do not have that luxury. Their hearing loss requires amplification with a bone-conduction hearing aid. There are usually three specialists involved in obtaining bone-conduction hearing aid. The primary care doctor usually refers to the child to an ear, nose and throat specialist. A hearing test is performed by an audiologist and this person is usually the one who dispenses and tests the hearing aid.

    If one wants to know what a child with bilateral microtia hears, it is rather simple to reproduce this Hearing loss. If one places a finger in each ear in order to totally occlude the ear canal, that is what a child with bilateral microtia and atresia hears. One may ask, then how can the child hear if both ear canals are occluded. The answer is simple: Bone Conduction. Because the vast majority of children with microtia have normal inner ears, sound travels via the skull via vibrations. In other words, a sound will strike the skull, nose, jaw, etc. And a vibration gets transmitted straight to the inner ears, totally bypassing the ear canals.
