of an inpatient in a Japanese hospital.
(10) reported that, among the patients they operated on with an initial diagnosis of COM and with a polypoid mass in the external ear canal

The right ear showed a large retained cotton swab in the medial end of the external ear canal
. The external ear canal
skin including the bony-cartilaginous junction was not inflamed.
After a routine ENT examination, skin samples were taken from the tragus medialis of the external ear canal

Fine-needle biopsy of external ear canal
masses in the cat: cytologic results and histologic correlations in 27 cases.
1) Cured: The tympanic membrane did not congest after surgery, and purulent secretions in the external ear canal
and otitis media symptoms disappeared; 2) remitted: the tympanic membrane still mildly congested after surgery, but purulent secretions in the external ear canal
and otitis media symptoms were significantly mitigated; 3) ineffective: the tympanic membrane was still congested after surgery, and purulent se- cretions or clinical symptoms were unalleviated or even aggravated.
Results of experiments have shown that, in particular, the signal components that travel through the external ear canal
