Case 1: A 52-year-old woman was sent to our clinic for suspected malignant tumor of the right external canal. The canal was filled with granulation tissue and purulent otorrhea. The head of a toothpick and a small piece of cotton were found in the left ear canal, so the right external canal was investigated for foreign bodies. Pieces of a decayed cotton ball were discovered in the granulation deep in the right external ear canal. After removal of the cotton and the oral administration of antibiotics, the granulation decreased dramatically, the tympanic perforation closed and her hearing returned to normal.Case 2: A 59-year-old woman, who was predisposed to allergic disease, complained of left tinnitus and hearing loss. Severe swelling of the left posterior external canal with purulent otorrhea was noted. A piece of cotton was seen in a smear of the pus. Removal of the cotton plug, local treatment and oral antibiotic administration relieved her symptoms immediately.Many patients with foreign bodies in the external ear canal have subjective symptoms. In patients who are not aware of a foreign body in the external canal, the diagnosis is difficult, and treatment may be refused. On the other hand, even patients with severe pathological findings show good improvement after removal of the foreign body. It is important to examine local findings in detail, to consider the possible presence of foreign bodies and to discuss ear hygiene at the time of treatment of granulation external otitis. Many patients with this disease have chronic external otitis as an underlying disease.
