Background: External ear consists of auricle or pinna and external acoustic meatus. The auricle projects to a variable and individual degree from the side of the head. It collects sound waves and conducts them on the external acoustic meatus inward to the tympanum. The auricle therefore acts because the1stcomponent of a series of stimulus modifiers within the auditory apparatus. The lateral surface of the auricle is on an irregular basis concave and faces slightly forwards. Its prominent curved rim, or helix, usually bears postero-superiorly a small auricular tubercle, a structure that is pronounced round the sixth month of intrauterine life, when the auricle closely resembles that of some adult monkeys. Another curved prominence, parallel and anterior to the posterior part of the helix, is the antihelix, dividing above into two crura flanking a depressed triangular fossa. Scaphoid fossa is curved depression between the helix and antihelix.
