失去嗅觉的患者通常自己去看医生，报告味觉丧失，炎症（通常是由于过敏），病毒感染和头部创伤是嗅觉障碍的常见原因，历史记录可能为这些和其他问题（例如，毒素暴露，先天性嗅觉障碍）提供线索。在标准化测试确定嗅觉受损之前，不应开始检查。唯一真正可逆的原因是炎症，在使用皮质类固醇治疗后，嗅觉恢复即可确认。鼻窦计算机断层扫描是观察嗅裂的必要条件；缺乏阻塞表明嗅觉障碍是不可逆转的。患者应该对他们的疾病和预后做出解释。如果他们的嗅觉不太可能恢复，应该提醒患者采取措施确保安全，如气体泄漏、烟雾和变质的食物。
Patients who have lost the sense of smell usually come to a doctor on their own, reporting loss of the sense of taste, Inflammation (often due to allergy), viral infection, and head trauma are common causes of olfactory disturbance, History taking may provide clues to these and other problems (eg, toxin exposure, congenital dysosmia).Workup should not begin until a standardized test has been given that establishes impairment of the sense of smell, The only truly reversible cause is inflammation, which is confirmed when smell returns after a course of corticosteroid. Sinus computed tomography is necessary to view the olfactory cleft; lack of obstruction indicates that smell impairment is nonreversible.Patients deserve an explanation for their disorder and a prognosis, If restoration of their sense of smell is unlikely, patients should be cautioned to take steps to ensure safety in regard to such dangers as gas leaks, smoke, and spoiled foods.
