A guide to Microtia: Home

Microtia - Latin meaning; small or underdeveloped ear

About

This guide is for people who have microtia or know someone with it as well as the general public. I believe that there isn’t enough awareness of this condition or knowledge about it.

Overview

  • Microtia is a congenital malformation of the ear and can often lead to hearing loss.
  • Microtia can be unilateral (one side only) or bilateral (affecting both sides).
  • In unilateral microtia, the right ear is most commonly affected.
  • Microtia occurs in 1 out of about 8,000–10,000 births. 
  • It occurs more commonly in males than females.
  • The cause of microtia in children remains uncertain but there are some cases that associate it with genetic defects in multiple or single genes, altitude, and gestational diabetes. 
  • Risk factors gathered from studies include infants born underweight, women gravidity and parity, and medication use while pregnant.
  • Genetic inheritance has not been fully studied but in the few studies available, it has shown to occur during the early stages of pregnancy.
