We have studied 77 patients belonging to the OAV-spectrum. These patie
nts were grouped into four different categories according to their cli
nical signs: Goldenhar syndrome, oculoauriculovertebral dysplasia, typ
ical hemifacial microsomia, and those only with pre-auricular tags, in
order to compare the frequency of associated anomalies and recurrence
rates. We have listed and compared our clinical findings with those f
ound in the literature. There are few associated anomalies in the last
group (pre-auricular tags) when compared with the other three groups,
indicating that pre-auricular tags could represent a distinct anomaly
.
