Accessory Auricles: Systematic Review of Definition, Associated Conditions, and Recommendations for Clinical Practice

J Craniofac Surg. 2018 Mar;29(2):372-375. doi: 10.1097/SCS.0000000000004201.

Abstract

Accessory auricles are rare congenital abnormalities embryologically derived from the first branchial arch. Presentation may be variable with locations grouped into anatomical zones based on the frequency of location found in the literature. This study reviewed the papers between 1981 and 2017. Findings included an association with syndromes including Goldenhar, VACTERL, Treacher-Collins, Townes-Brocks, and Wolf-Hirschhorn. Based on histological and embryological evidence, the term "accessory auricle" is best used as an umbrella term to define this difference. Finally, indications are provided for imaging and laboratory investigations to guide the physician treating patients with accessory auricles.
