Concurrent Occurrence of Ear Tag With Posterior Talon Cusp, Fissured Tongue, and Ankyloglossia: A Case Report

Ear tags or accessory auricles are branchial cleft remnants that clinically appear as asymptomatic nodules or papules in the preauricular region. They occur in various syndromes affecting the first and branchial arches during embryogenesis. The presence of an ear tag can have a psychological impact on one's life due to its unesthetic appearance, thereby affecting their quality of life. Talon cusp usually occurs in the maxillary central or lateral incisor. A fissured tongue or cerebriform tongue is characterized by the presence of horizontal or vertical grooves, usually affecting the dorsum of the tongue. Ankyloglossia or tongue-tie is a developmental anomaly in which the lingual frenum is abnormally attached to the ventral surface of the tongue. It can cause difficulties in breastfeeding in infants and in the pronunciation of certain vowels in adults. The concurrent occurrence of the ear tag along with the talon cusp in the mandibular second molar has not been reported in previous literature. We present a unique case of a 24-year-old non-syndromic individual with the concurrent occurrence of the ear tag along with a rare clinical occurrence of talon cusp in the mandibular second molar, fissured tongue, and ankyloglossia.
