OBJECTIVE
To investigate the relationship between nasal obstruction and lip-closing force.
MATERIALS AND METHODS
Nasal airway resistance and lip-closing force measures were recorded for 54 Japanese females. The subjects were classified into normal and nasal obstruction groups according to nasal airway resistance values. Differences between the normal and nasal obstruction groups in lip-closing force were tested statistically. Correlation coefficients were calculated between the measures for the normal and nasal obstruction groups.
RESULTS
Lip-closing force for the nasal obstruction group was significantly less than for the normal group (P < .05). In the normal group, nasal airway resistance did not correlate with lip-closing force, while in the nasal obstruction group a significant negative correlation was found between nasal airway resistance and lip-closing force (P < .05).
CONCLUSIONS
Nasal obstruction is associated with a decrease in lip-closing force. When the severity of nasal obstruction reaches a certain level, the lip-closing force is weakened.
目的
探讨鼻塞与闭唇力的关系。
材料与方法
对 54 名日本女性进行了鼻腔气道阻力和闭唇力测量。根据鼻腔气道阻力值将受试者分为正常组和鼻塞组。比较两组间闭唇力的差异，并对正常组和鼻塞组的测量值进行相关性分析。
结果
鼻塞组的闭唇力明显小于正常组（P<0.05）。在正常组中，鼻腔气道阻力与闭唇力无相关性，而在鼻塞组中，鼻腔气道阻力与闭唇力呈显著负相关（P<0.05）。
结论
鼻塞与闭唇力下降有关。当鼻塞的严重程度达到一定水平时，闭唇力会减弱。
