This study evaluates if a computed tomography (CT) scan is useful to assess the olfactory loss in sinonasal disease, and if a preoperative CT scan has a predictive value for the long-term outcome regarding olfaction.
Thirty-one patients with nasal polyposis were included. Olfactory function was assessed with the 'Sniffin' Sticks' test and subjective perception recorded with a visual analogue scale. CT scans were assessed with the Lund-Mackay system and the Damm nasal segmentation. Patients were retested after endoscopic sinus surgery in a follow-up appointment at least 1 year later.
Disease in the upper meatus and the posterior portion of the middle meatus strongly affects olfactory function. Lund-Mackay scores were significantly correlated with preoperative olfactory test results. Preoperative subjective ratings had a significant correlation only with present disease in the anterior upper meatus. Postoperative results were significantly decreased. Their relative percentage change was correlated only with the preoperative presence of disease in the anterior upper meatus. No correlation was found between the Lund-Mackay score and the postoperative olfactory results.
Olfactory dysfunction in nasal polyposis is strongly related to specific obstructed nasal areas. A CT scan has no predictive value for the long-term surgical outcome regarding olfaction.
本研究评估计算机断层扫描（CT）对评估鼻窦疾病嗅觉丧失是否有用，以及术前CT扫描对嗅觉的长期预后是否具有预测价值。
纳入31例鼻息肉患者。采用“嗅觉棒”测试评估嗅觉功能，并用视觉模拟量表记录主观感受。采用Lund-Mackay系统和达姆鼻腔分段法评估CT扫描结果。患者在内镜鼻窦手术后至少1年的随访预约中接受重新测试。
上鼻道和中鼻道后部的病变严重影响嗅觉功能。Lund-Mackay评分与术前嗅觉测试结果显著相关。术前主观评分仅与上前鼻道的现有病变显著相关。术后结果显著下降。其相对百分比变化仅与术前上前鼻道疾病的存在相关。未发现Lund-Mackay评分与术后嗅觉结果之间存在相关性。
鼻息肉患者的嗅觉功能障碍与特定的鼻腔阻塞区域密切相关。CT扫描对嗅觉的长期手术预后没有预测价值。
