Effects of decongestion on nasal cavity air conditioning efficiency: a CFD cohort study

Scientific Reports
Decongestion reduces blood flow in the nasal turbinates, enlarging the airway lumen. Although the enlarged airspace reduces the trans-nasal inspiratory pressure drop, symptoms of nasal obstruction may relate to nasal cavity air-conditioning.

[Language tests for the examination of nasal resonance].

Otolaryngologia polska = The Polish otolaryngology, 1997
A set of 7 word tests with different number of nasal phonemes was prepared. These tests are adjusted to technical possibilities of nasal resonance examination by means of own construction apparatus. The VII-th test consisting only oral speech sounds appeared to be most important for estimating physiological nasal resonance characteristic for the Polish
