An area of the scalp was shaved above the ear and then also 1% Xylocaine with 1:200,000 epinephrine injected, a total of 4 mL local anesthetic was used.  The ear was then prepped and draped in the usual sterile fashion.  The microscope was then brought into view and examining the marginal perforation, the patient was noted to have large granuloma under the tympanic membrane at the anterior border of the drum.
