面； 平面

I have seen cats with squamous cell carcinoma lose the pigment in the nasal planum as an early sign. 我看到過貓患有的鱗狀細(xì)胞腫瘤的初期會在鼻平面上出現(xiàn)色素減退。

There are also usually skin sores around the edges of the nasal planum, on the bridge of the nose, around the eyelids or places like that. 通常在鼻平面的邊緣會有皮膚發(fā)炎，或是在鼻梁，眼皮的位置等等。
