Auricular appendages, skin tags, dermal appendages and cartilage are
probably the most common malformation of the ear (1.5% of the population) (1).
- Often unilateral.
- Vary in size from sessile
protuberances to polypoidal projections.
- Occur most commonly in the
line of fusion of the mandibular and hyoid arches and less frequently in
the fusion line of the maxillary process and mandibular arch (may be
associated with melotia).
- They vary in size and may
simulate the shape of the pinna.
- They may be associated with
microtia or facial fissures.
- They are rarely associated
with conductive or sensorineural hearing loss (which is usually
ipsilateral) (2).
