[The effect of various types of nasal septal deviation, concha bullosa and hypertrophic inferior turbinate on the development of sinusitis].

OBJECTIVE

To determine the impact of various types of unilateral nasal septum deviation (NSD), (CB) and hypertrophic inferior turbinate (HIT) on the development of sinusitis.

MATERIAL AND METHODS

This study was conducted in the Irkutsk State Medical University and the Irkutsk City Clinical Hospital No. 1 from October 2017 to November 2018. By continuous sampling retrospective analysis of 1300 protocols of paranasal sinuses MSCT of adult patients was performed. We used MSCT scanners Somatom Emotion 16 Siemens and GE BrightSpeed 16. The studies were carried out on the patients lying on the back with the subsequent reconstruction on a graphical station in the coronal and axial projections using the slices around 1 mm in the thickness. Inclusion criteria: unilateral or absence NSD. Exclusion criteria: bilateral NSD, chronic polyposis or allergic rhinitis. We have analyzed 272 protocols: 70 without NSD and 172 with unilateral NSD, on the right side - 89 (52%) and on the left - 83 (48%). 108 (44.6%) patients were male and 134 (55.4%) were female with average age 38.5±12 years. All patients were divided into 4 groups by R. Mladina' classification (1987): with NSD types 1, 2, 3, and 5. The results were evaluated using the Yates corrected chi-square and the Fisher's exact test by Statistica 10.0.

RESULTS

There were 34 patients with NSD type 1: 12 with sinusitis; 9 had CB: 6 with sinusitis, 3 without it; HIT was in 27 cases: 33% with sinusitis, 67% without it. There were 69 patients with NSD type 2: 12 had sinusitis; 22 had CB: 5 with sinusitis, 17 without it; HIT was in 42 cases: 26% with sinusitis, 74% without it. There were 43 patients with NSD type 3: 26 had sinusitis; 15 had CB: 6 with sinusitis, 9 without it; 30 had HIT: 57% with sinusitis, 43% without it. There were 26 patients with NSD type 5: 11 had sinusitis; 9 had CB: 3 with sinusitis, 6 without it; 24 had HIT: 42% with sinusitis, 58% without it. NSD type 2 was statistically significant prevailed in patients without sinusitis (=0.000005); NSD type 3 (=0.03) and the combination of NSD type 1 with contralateral CB (=0.04) prevailed in patients with sinusitis.

CONCLUSION

NSD type 3 (by R. Mladina), as well as the combination of type 1 with contralateral CB are have influence to the development of sinusitis. CB and HIT are statistically significant prevailed on the contralateral side to unilateral NSD, but do not affect to development of sinusitis.
