The Correlation Of Concha Bullosa And Nasal Septal Deviation And Their Relationship To Chronic Rhinosinusitis

Objective:To discuss the correlation of bulbous type concha bullosa and nasal septal deviation, and analysis their relationship to chronic rhinosinusitis.Methods:1. The statistics of our study was based on the paranasal sinus coronal plane CT scans of972patients.2. Observe the incidence of bulbous type concha bullosa in the patients with or without nasal septal deviation, with upper septal deviation or lower septal deviation, and measure the transverse diameter of bulbous type concha bullosa, analysis the relationship between bulbous type concha bullosa and nasal septal deviation.3. Observe the incidence of chronic rhinosinusitis and bulbous type concha bullosa and analysis the relationgship between bulbous type concha bullosa and chronic rhinosinusitis, measure the transverse diameter of bulbous type concha bullosa, use the average transverse diameter to evaluate the size of the bulbous type concha bullosa. At the same time, observe the existence of unilateral or bilateral bulbous type concha bullosa whether has signs of chronic rhinosinusitis, and analysis the relationship between the transverse diameter of bulbous type concha bullosa and chronic rhinosinusitis.4. Observe the incidence of nasal septal deviation, classify them into upper septal deviation and lower septal deviation, and analysis the relationship between nasal septal deviation and chronic rhinosinusitis.Results:1. The incidences of chronic rhinosinusitis and bulbous type concha bullosa were22.63%and9.72%in972patients. There were142patients of bulbous type concha bullosa, including95patients of unilateral concha bullosa and47patients of bilateral concha bullosa. The incidence of nasal septal deviation was18.72%, including60patients of upper septal deviation and122patients of lower septal deviation.2. There was no statistical difference of the incidence of bulbous type concha bullosa between the cases with nasal septal deviation and without nasal septal deviation(P>0.05). Of the cases with upper septal deviation and lower septal deviation, the incidences of bulbous type concha bullosa were16.67%and4.92%, the incidences of bulbous type concha bullosa in concave side were33.33%and4.55%, statistical difference was found between them(P<0.05). The average transverse diameter of bulbous type concha bullosa were5.58±1.79mmå'Œ4.12±1.78mm in cases with and without nasal septal deviation, the difference was statistically significant(P<0.01). But the average transverse diameter of bulbous type concha bullosa were5.92±1.87mm in cases with upper septal deviation and4.80±1.35mm in cases with lower septal deviation, the difference was not statistically significant(P>0.05).3. Of95patients who had unilateral bulbous type concha bullosa the incidences of chronic rhinosinusitis were36.84%in CB sides and21.15%in non-CB sides, the incidences of chronic rhinosinusitis were50.00%in cases with bilateral bulbous type concha bullosa and20.36%in cases without bulbous type concha bullosa, statistical difference was found between them(P<0.05). There was no statistical difference between the transverse diameter of bulbous type concha bullosa and chronic rhinosinusitis(P>0.05).4. The incidences of chronic rhinosinusitis were32.97%in cases with nasal septal deviation and27.47%without nasal septal deviation, the difference was not statistically significant (P>0.05). But the incidence of chronic rhinosinusitis was statistically different in cases with upper septal deviation and lower septal deviation(P<0.05). Whether in upper septal deviation or lower septal deviation, the incidence of chronic rhinosinusitis was not statistically different between the convex sides and concave sides of nasal septum(P>0.05)Conclusion:1. There was a significant relationship between upper nasal septal deviation and bulbous type concha bullosa, especially finding bulbous type concha bullosa in concave sides of nasal septum.2. The relationship between bulbous type concha bullosa and chronic rhinosinusitis was significant, but there was no significant relationship between the size of the bulbous type concha bullosa and chronic rhinosinusitis.3. There was significant relationship between upper septal deviation and chronic rhinosinusitis.
