失嗅

方法：8例外伤后失嗅病人行MRI检查，观察并记录嗅球及皮层损伤情况，测量嗅球体积体积。并与12例健康志愿者对照。

Methods : 8 patients with posttraumatic anosmia and 12 normal volunteers underwent MR examination . In anosmic patients , the injury of olfactory bulbs and related cortex was visualized and recorded .

失嗅症组嗅上皮中细胞凋亡指数（AI）高于嗅觉正常组（P<0.05）。

At the same time , the apoptosis index ( AI ) in the olfactory epithelium of the 26 cases suffering from dysosmia was higher than that in the control group ( P < 0.05 ) .

术前嗅觉检查均为嗅觉缺失，失嗅时间5～30年，平均11.8年。

All patients were diagnosed to have anosmia by olfactory tests before the operation . The history ranged from 5 to 30 years .

其中鼻塞、头痛、脓涕及失嗅症状消失率分别为95.2%，92.0%，66.7%，42.1%；

The disappearance rate of four symptons & nasal obstruction 、 headache 、 purulent nasal discharge and loss of smelling was 95.2 % 、 92 % 、 66.7 % and 42.5 % , respectively .
