Introduction. The aim of this paper is to determine the influence of nasal
septum deformity degree on the subjective nasal breathing assessment as well
as the existence of correlation between one side of the nose with nasal
septum deformity and the subjective feeling of difficulty in breathing on
that side in the subjects with different degrees of nasal septum deviation.
Material and Methods. The research included 90 randomly chosen patients, who
claimed to have nasal breathing difficulties. Every patient assessed
subjectively which side of the nose made breathing difficult and scored the
breathing on that side from 0 to 10 cm on the visual analogue scale. Results.
The patients from the third group described their breathing as the most
difficult, while the subjects from the first group claimed that their nasal
breathing problems were the least difficult. The subjective feeling of heavy
nasal breathing on the deformed nasal septum side was significantly different
in all groups (H= 38.466, p= 0.000). In the second and the third group of
patients there was a significant correlation between the deformed side of the
nose and the subjective heavy breathing on that side (p< 0.05), whereas this
correlation was not found in the first group (p> 0.05). Conclusion. The
subjective feeling of difficulty in breathing on the deformed side of the
nose is intensified with the degree of the nasal septum deformity, thus this
feeling was reported only by the subjects with a higher degree of the nasal
septum deformity.
