Nasal vestibule wall elasticity: interactions with a nasal dilator strip.
We studied the effect of an adhesive external nasal dilator strip (ENDS) on external nasal geometry in 20 healthy Caucasian adults (10 men, 10 women; age 21-45 yr). The recoil force exerted by ENDS was estimated by bending the device (n = 10) with known weights. In the horizontal direction, a small/medium-sized ENDS in situ exerted a unilateral recoil force of 21.4-22.6 g. Application of ENDS r...
متن کاملSnoring can be reduced when the nasal airflow is increased by the nasal dilator Nozovent.
The ability to breath through the nose can be increased above normal by dilating the narrow nasal valve area with the plastic nasal device Nozovent. For 10 nights, 10 patients used Nozovent every other night, and the sleeping partners of the patients judged the snoring sound level using a snoring score. The results showed a significant decrease in snoring, from moderate to slight, when Nozovent...
متن کاملCombined effects of a nasal dilator and nasal prongs on nasal airflow resistance.
STUDY OBJECTIVES Nasal prongs (NPs), when used to assess nasal flow, can result in dramatic increases in nasal airflow resistance (NR). The aim of this study was to investigate whether the NP-induced increases in NR could be corrected by the simultaneous use of an internal nasal dilator (ND). DESIGN NR was estimated by posterior rhinomanometry, in the basal state (NRb), and while breathing wi...
متن کاملEffects of the nasal strip and dilator on nasal breathing--a study with healthy subjects.
OBJECTIVE To investigate effects of the nose dilating devices on nasal anatomy and breathing in healthy subjects. MATERIALS AND METHODS 27 healthy subjects were tested when using the Breathe Right nasal strip or the Nozovent dilator. Posterior rhinomanometry, acoustic rhinometry, and a subjective evaluation were used as methods. RESULTS Both devices significantly increased the minimum cross...
متن کاملContractile properties of human nasal dilator motor units.
The technique of intramuscular microstimulation was used to activate facial nerve fibers while acquiring simultaneous twitch force measurements to measure the contractile properties and force-frequency responses of human nasal dilator (ND) motor units. Twitch force amplitude (TF), contraction time (CT), half-relaxation time (HRT), and the maximal rate of rise of force normalized to the peak for...
