对筛选出的鼻腔良性阻塞性嗅觉异常的39例（62侧）鼻腔进行CT及鼻内窥镜检查，发现因中鼻甲变异致嗅裂消失者14侧（22.58％），筛泡肥大及中鼻道息肉26侧（41．93％），中鼻道合并嗅裂息肉15侧（24.19％），鼻中隔高位偏曲4侧（6.45％）。鼻中隔代偿性肥厚3侧，经功能性鼻窦内窥镜手术处理后，对其嗅觉变化进行了动态观察，发现术后12周嗅觉治愈率为48．4％（30／62），嗅觉好转为25.8％（16／62），25.8％（16／62）无变化。鼻窦炎越严重者，嗅觉恢复越慢，由此认为嗅觉障碍常与中鼻甲变异，窦口鼻道复合体及嗅裂的阻塞和炎症有关，早期处理上述病变，可使嗅觉有较好的恢复。
Thirty-nine patients (62 sides) with nasal cavity obstructive olfactory dysfunction were screened by CT and nasal endoscopy. 14 cases (22.58%) with disappearance of olfactory fissure caused by middle turbinate were found, 26 cases of polyp (41.93%), 15 cases (24.19%) of nasal polyps combined with olfactory bulb rupture and 4 sides (6.45%) of high nasal septum. Nasal septum compensatory hypertrophy 3 side, after functional endoscopic sinus surgery, its changes in the olfactory dynamic observation and found that 12 weeks after the olfactory cure rate was 48.4% (30/62), the olfactory improved to 25.8% (16/62), 25.8% (16/62) no change. The more serious sinusitis, the slower the recovery of the sense of smell, which often associated with olfactory disorders and middle turbinate variability, ostiomeatal complex and olfactory fissure obstruction and inflammation related to early treatment of these lesions can make a good sense of smell recovery .
