背景:嗅覺喪失是慢性鼻竇炎一個常見的症狀。許多方法已經被用來評估慢性鼻竇炎患者之嗅覺功能,主觀評估是傳統方法。一些心理物理方法已經被發展出來,包括閾值測試、分辨測試及記憶測試。可是,這些方法的關聯性尚未被檢驗。 方法:80名將接受功能性內視鏡鼻竇手術的慢性鼻竇炎患者被收錄在本研究。在手術前1日,他們的嗅覺功能利用問卷調查、嗅覺閾值測試、賓州大學嗅覺分辨測試及嗅覺記憶測試來評估。結果用Spearman關聯分析法來分析。 結果:問卷調查的結果和嗅覺閾值測試、賓州大學嗅覺分辨測試及嗅覺記憶測試的結果是高度相關。嗅覺閾值測試、賓州大學嗅覺分辨測試及嗅覺記憶測試的結果互相之間也是高度相關。 結論:本研究顯示慢性鼻竇炎患者之嗅覺功能能有效的利用問卷調查、嗅覺閾值測試、賓州大學嗅覺分辨測試或嗅覺記憶測試來評估。
BACKGROUND: Olfactory loss is a common symptom of chronic sinusitis. The olfactory function in patients with chronic sinusitis has been evaluated by different methods. Subjective evaluation is the traditional method. Several psychophysical methods have been developed, including threshold tests, identification tests and memory tests. However, the correlation between these methods has not been tested. METHODS: Eighty patients with chronic sinusitis who were scheduled to undergo functional endoscopic sinus surgery were included in this study. On the day before surgery, their olfactory functions were evaluated by questionnaires, the Smell Threshold Test(superscript TM) (STT), the University of Pennsylvania Smell Identification Test(superscript TM) (UP SIT) and the Odor Memory Test(superscript TM) OMT. The results were correlated by Spearman correlation analysis. RESULTS: The answers to questionnaires were highly correlated with the results of STT, UPS1T and OMT (p<0.01). The results of SIT, UPS1T and OMT were also well correlated with each other (p<0.0l). CONCLUSIONS: The study showed that the olfactory functions of patients with chronic sinusitis could be evaluated well by questionnaires, STT, UPSIT or OMT.
