   • Unquestionably, gentlemen, the bones most liable to exostosis are, first, the femur; secondly, the humeri; and thirdly, the lower jaw. But exostoses are met with on the sternum clavicle, and the bones of the head; in short, I may state, that there are no bones on which exostoses may not be produced.1834, Samuel Cooper, “Lectures on the Principles, Practice, & Operations of Surgery: Lecture LXIV”, in Michael Ryan, editor, The London Medical and Surgical Journal, volume 4, Henry Renshaw, page 516
   • Exostoses are the most common benign tumors of the EAC.^([External Auditory Canal])2009, Mauricio Castillo, Valerie L. Jewells, Craig Buchman, “2: The External Auditory Canal and Pinna”, in Joel D. Swartz, Laurie A. Loevner, editors, Imaging of the Temporal Bone, 4th edition...
