a condition in which the inside of the ear becomes swollen and painful

It is important to have your pet seen for otitis as it can result in a burst eardrum and deafness if not treated. 宠物得了耳炎一定要及时就诊，因为如果不及时治疗，可能会导致耳膜爆裂、耳聋。

Malignant otitis requires the use of systemic antibiotics for nearly two months. 恶性耳炎需要使用全身性抗生素近两个月时间。
