Auricular petrification is a rare diagnosis and presents an interesting therapeutic challenge. Fewer than 160 cases have been reported in the literature since the first description by Bochdalek in 1866. The most common etiology is ectopic calcification. It may also result from injurious processes including frostbite, physical trauma, inflammatory conditions, and various endocrinopathies. We report an incidental finding of idiopathic bilateral auricular petrification in a 40-year-old man presenting with idiopathic unilateral sensorineural deafness.
Auricular petrification refers to calcification within the auricle. This should be differentiated from the much rarer auricular ossification, which involves the formation of lamellar bone with fibrous tissue, fat cells, and haversian canals and which can only be diagnosed histologically.
We report the case of a 40-year-old man with auricular petrification.
