Understanding Quinquelobate Ear: Causes, Symptoms, and Treatment Options

Quinquelobate is a rare congenital malformation of the ear, characterized by a depression or notch in the upper part of the helix (the curved outer rim of the ear). It is also known as "quinquelobular notch" or "quinquelobate ear". The condition is usually present at birth and can be inherited in an autosomal dominant pattern.

The name "quinquelobate" comes from the Latin words "quinque," meaning five, and "lobus," meaning lobe, referring to the five lobes that are typically present in a normal ear. In individuals with quinquelobate ear, one or more of these lobes are missing or deformed, resulting in a distinctive appearance.

The exact prevalence of quinquelobate ear is not well established, but it is believed to be a rare condition. Treatment for the condition may include hearing aids or other assistive devices to help improve hearing and address any related ear problems.
