同时请注意其他副鼻窦广泛的病变。

Purpose : To explore the CT features of malignant lymphoma in nasal cavity and paranasal sinuses.

目的: 探讨鼻腔鼻窦恶性淋巴瘤的CT特点.

Method:six cases of osteoblastoma of the nasal cavity and paranasal sinuses were analyzed retrospectively.

方法：对6例鼻腔鼻窦骨母细胞瘤患者的临床资料进行分析。

Cancer of the nasal passages affects the paranasal sinuses (the small cavities in the bone surrounding the nose) and the breathing passages in the nose.

鼻癌影响鼻旁窦（鼻旁骨质内的小腔腺）和鼻内的呼吸通道。

Air that is inhaled through the mouth bypasses the nasal canal and the paranasal sinuses and is not filtered, warmed, and humidified as it is when inhaled through the nose.

从嘴巴进入的空气绕开了鼻泪管和鼻旁窦，不通过鼻腔的过滤、温暖和湿润就被人体直接吸入。
