Outcome and Prognosis The goal of congenital aural atresia (CAA) surgery is to restore hearing to a speech-reception threshold (SRT) of less than or equal to 30 dB HL without the need for amplification. [microtiaexpert.com]

Etiology The etiology of microtia is often multifactorial. Only 15 % of patients have a positive family history. [entokey.com]

Etiology: 1. Exposure to teratogens like vitamin A 2. Vascular insults and genetic aberrations 3. Isolated microtia can occur with branchial arch anomalies 4. Can occur as a part of a single gene deletion or embryopathic development anamolies, eg. [drtbalu.co.in]
