Just in front of the short process of malleus. A total of 8 cases of chondroma of the EAC, including the current case and 7 previously reported cases, were reviewed. All of the EAC tumors were single, unilateral, and originated from the tympanosquamous or tympanomastoid suture. The Chondroma of the EAC were usually asymptomatic.
