1년 간 우측 귀에 재발성 외이염을 앓다가 이도 내 종괴가 발견된 19개월령의 중성화된 수컷 잡종 고양이에서 종괴의 제거를 시행하였다. 전신마취 후 2.7 mm 내시경을 우측 이도로 삽입하였으며, 원활한 시야 확보를 위해 이도 내 세척을 동시에 시행하였다. 이도 내에서 4.9 mm 직경의 둥근 붉은색 종괴가 확인되었고 traction-avulsion 방법으로 제거되었다. 제거 후 고막 파열이 확인되었으며, 고실 내의 삼출물 제거를 위해 0.9% 멸균생리식염수로 귀를 플러싱하였다. 제거된 종괴는 조직검사 결과 심한 궤양을 동반한 육아조직으로 진단되었다. 술 후 환축은 특별한 부작용을 나타내지 않았으며, 5개월이 경과된 현재 재발의 징후는 발견되지 않았다. 비디오 이경검사법의 사용은 고양이 염증성 폴립의 치료를 위한 효과적인 방법이 될 수 있을 것으로 생각된다.

Otic mass removal was performed in a 19-month-old, castrated domestic shorthair cat. The patient had 1- year history of recurrent otitis externa, and then otic mass in the right ear canal was found. Under general anesthesia, 2.7 mm rigid endoscope was inserted to the right ear canal with the irrigation system. The ovoid-shaped, 4.9 mm in diameter red otic mass located in the right ear canal was removed via traction-avulsion. Then, rupture of the tympanic membrane was revealed and otic flushing was performed with sterile isotonic (0.9%) saline to remove exudates. Histologically, the removed polyp was diagnosed as granulation tissue with severe ulceration. The patient didn't reveal any remarkable abnormality after surgery, and no recurrence were found after 5 months follow up. The video otoscopy seems to offer a useful option for treatment of a feline inflammatory polyp.

제안 방법
In this report, the patient underwent traction-avulsion of the inflammatory polyp, though traction-avulsion method had a disadvantage in terms of recurrence. According to previous studies, treatment with traction-avulsion alone showed a higher rate of recurrence when compared to other surgical methods like ventral bulla osteotomy (1,17).
A 19-month-old, 5 kg, castrated male domestic shorthair cat was referred to the Gyeongsang National University Animal Medical Center for removal of mass in the right ear canal. The patient had 1-year history of recurrent otitis externa with scratching, rubbing the ear, and head shaking. There were no notable improvements presented during few months of typical treatment at the local animal hospital, and then otic mass in the right ear canal has been found by handheld otoscopy lately.

The patient discharged on that day and prescribed to give a daily PO administration of 5 mg/kg enrofloxacin (Baytril®, Bayer Korea Ltd, Korea) for 4 weeks. Tissue sample submitted to the commercial pathology laboratory (Neodin Vetlab, Korea). Histologically, polyp diagnosed as granulation tissue with severe diffuse ulceration of mucosal epithelium including large numbers of degenerative neutrophils.
성능/효과
The patient didn’t reveal any remarkable abnormality after surgery, and no signs of recurrence were found after 5 months follow up.
