摘要
目的：探讨成人、儿童鼻周期的类型、特点及鼻粘膜病理状态对鼻周期的影响。方法：应用声反射鼻测量计测量了１６ 例正常成人，１１ 例正常儿童，１４ 例双侧鼻阻塞患者的鼻周期。测量时间为４～８．５ ｈ，间隔时间为３０ ｍ ｉｎ（儿童组为２０ ｍ ｉｎ）。结果：所有受试者均有明显的鼻周期。正常成人组及鼻病组以典型鼻周期为最常见，正常儿童组以一致型为最常见。鼻病组与正常成人组之间在鼻周期类型、周期时间方面无明显差异（均Ｐ＞ ０．０５），但鼻腔容积变化幅度小于正常成人组（ Ｐ＜ ０．０１）。正常儿童组鼻周期类型分布不同于正常成人组（Ｐ＜ ０．０１），周期时间显著短于正常成人组（ Ｐ＜ ０．０１），鼻腔容积变化幅度小于正常成人组（ Ｐ＜ ０．０１）。结论：以上结果提示鼻周期系中枢控制、局部调节。儿童鼻周期类型以一致型为主。
Objective:The aim of this article was to study the classifications and characteristics of nasal cycle of adult and children and the influence of pathological state of nasal mucosa on nasal cycle with acoustic rhinometry.Method:We examined the nasal cycle of 16 healthy adults,11 healthy children and 14 patients with bilateral nasal obstruction.Acoustic rhinometry was performed every 30 minutes (20 minutes in children) over 4~8.5 hours to determine minimum cross sectional area of nasal cavity (MCA) and nasal cavity volume (NV) which were used as indices of nasal patency.Result:Nasal cycles were observed in all subjects.Classical nasal cycle was most commonly observed in healthy adults and patients with nasal diseases.In healthy children,in concert nasal cycle was the most common type.The distribution of the healthy adults and patients with nasal diseases between the cycle categories was not statistically significant different (P> 0.05 ),the mean periodicity of the cycle was no significantly different between these two groups (P> 0.05 ).The mean alteration amplitude of nasal cycle of healthy adults was significantly longer than that of patients with nasal diseases (P< 0.01 ).The distribution of the healthy children and the healthy adults between the cycle categories was significantly different (P< 0.01 ),the mean periodicity of the cycle of healthy children was distinctively shorter than that of healthy adults (P< 0.01 ).Conclusion:The above results illustrated that nasal cycle exists as central control and local modulation.In healthy children,in concert nasal cycle was most commonly observed and this may be related with the immature condition of their autonomic nervous system.
