We assessed prospectively changes in olfaction and ciliary beat frequency (CBF) after functional endoscopic sinus surgery (FESS) in 70 patients with chronic sinusitis. CBF was measured by the microscopic-photometry technique 2, 4 and 6 months after FESS. Olfaction was evaluated by the Erlangener Smell Identification Test. Preoperative CBF was markedly reduced due to the infectious process. CBF was significantly improved (p < 0.001), reaching normal values 6 months postoperatively despite the endoscopic examination revealing normal nasal mucosa at around 3 months. The pattern of improvement of CBF was linear being more rapid between months 4 and 6. After operation olfactory-impaired patients were improved subjectively and objectively (p < 0.001 and p = 0.003). We conclude that impaired olfactory ability and CBF are significantly improved after FESS, and FESS demands longer postoperative follow-up periods for at least 6 months even if the clinical evaluations were normal.
我们前瞻性地评估了70例慢性鼻窦炎患者在功能性鼻内镜鼻窦手术（FESS）后嗅觉和纤毛摆动频率（CBF）的变化。在FESS术后2、4和6个月，通过显微光度测量技术测量CBF。通过埃尔朗根嗅觉识别测试评估嗅觉。术前由于感染过程，CBF显著降低。CBF显著改善（p<0.001），尽管内镜检查显示术后约3个月鼻粘膜正常，但术后6个月CBF达到正常值。CBF的改善模式呈线性，在第4至6个月之间更为迅速。术后嗅觉受损的患者在主观和客观上均有改善（p<0.001和p=0.003）。我们得出结论，FESS术后嗅觉能力和CBF显著改善，即使临床评估正常，FESS也需要至少6个月的更长术后随访期。
