 We presented 10 cases of carcinoma of external auditory canal(EAC)treated by the middle ear preservation operation. Partial resection of the EAC was done in 4 cases for T1 case and en bloc resection of the EAC together with tympanoplasty in 6 cases for T1 and T2 case. Some of the patients who underwent en bloc resection of the EAC together with tympanoplasty preserved or improved their hearing after the operation compared with operative method of obliteration of the EAC. They had a good prognosis expect for a patient discontinued to visit the hospital. We considered that en bloc resection of the EAC together with tympanoplasty for T1 and T2 cases improves a high QOL of the patients.
