Accessory auricles are benign malformations seen at birth.1 They are found in 1.5% of the population, frequently in the preauricular region, and may be single or multiple.1,2 They are often unilateral but may also be bilateral.
More unusually, they are found farther away from the auricle in a zone extending toward the angle of the mouth.3 This zone corresponds to the line in which the maxillary and mandibular processes of the first branchial arch grow together. Recent cases of preauricular skin tags, including skin tags near the oral commissure (unusual position) (Figure), prompted us to discuss the therapy of this condition.
Accessory auricles may be part of a complex of malformations, which include anomalies of the eye, ear, and buccal and possibly the vertebral regions (eg, Goldenhar syndrome, hemifacial microsomia, or Wildervanck syndrome).4 Accessory auricles are unsightly (especially those near the oral commissure) and may be
