Bony over growths of the ear canal are a frequent incidental finding and occasionally have clinical significance
Clinically, they present as skin-covered bony mounds in the medial ear canal obscuring the tympanic membrane to a variable degree
Solitary osteomas are of no significance as long as they do not cause obstruction or infection
Multiple exostoses, which are generally acquired from repeated exposure to cold water (eg, “surfer’s ear”), may progress and require surgical removal
