[Influence of an internal nasal dilator (Nasanita) on nasal flow in healthy adults].
Influence of an Internal Nasal Dilator (Nasanita) on Nasal Flow in Healthy Adults. In a prospective, randomized study the influence of dilatation of the vestibulum nasi by an internal dilatator type Nasanita on the nasal flow of healthy adult persons was tested. Primary target was the inspiratory nasal flow as measured by rhinomanometry. Secondary targets were subjective evaluation of the nasal breathing and the judgement of the subjects on the comfort of carrying the stent. The insertion of the stent type Nasanita increased the nasal flow from 614 +/- 151 ccm/sec about 54 % to 920 +/- 198 ccm/sec (p = 0,00000016). The expiratory nasal flow increased from 622 +/- 169 ccm/sec about 55 % 928 +/- 230 ccm/sec (p = 0,0000008). Subjectively the insertion of the stent improved the nasal breathing slightly to significantly. The comfort of wearing was classified mostly indifferent to slightly unpleasantly. The internal nasal stent Nasanita has proven to be an agent to increase nasal flow significantly.
