Abstract

A number of minor variations to the configuration of the external ear are well recognized. This paper brings attention to one entity which is characterized by a small cartilaginous nodule or prominence arising from the posterior surface of the pinna and which we have named Quelprud's nodule. A prospective clinical survey of 208 patients attending an ENT clinic revealed that nearly one-third of the population studied possess this nodule. There was an equal sex incidence. The Quelprud's nodule was identified within families in a distribution which suggests an autosomal dominant inheritance with variable expressivity.
