Concha Bullosa and Its Association with Chronic Sinusitis

Objective: To determine the proportion and the distribution of concha bullosa in patients with Chronic sinusitis and to determine the relationship between concha bullosa and age, sex, laterality, symptoms, mucosal changes and others. Design: Retrospective study. Setting: Otorhinolaryngology, head and neck surgery department. Method: Computed Tomography Paranasal sinus done in 120 patients suffering from Chronic sinusitis between 2010 and 2013 were reviewed. Distribution of Concha Bullosa and its association with Chronic sinusitis was tested using chi-square tests. Result: The incidence of Concha bullosa in Chronic sinusitis was 45%. Patient’s age ranged from 16 to 54 years and mean age of patients with concha bullosa was 28.61 years. Out of 69 males, 43.47% had CB. Out of 51 female, 47.06% had concha bullosa. Most common symptom was nasal obstruction and seen in 72.22% of patient. There was no evidence of the predominance of concha bullosa on any one side. There was significant relation between concha bullosa & mucosal changes in maxillary sinus. Conclusion: Concha bullosa is a common occurrence in the nasal cavity with no correlation between concha bullosa and age, sex and laterality. There is statistically significant relationship between the presence of concha bullosa and mucosal changes in maxillary sinus but no correlation with mucosal changes in anterior ethmoidal cells, posterior ethmoidal cells, frontal sinus and sphenoid sinus.
