Introduction: Although sinusitis is a clinical diagnosis, imaging studies are used to
assess the extent of the disease and demonstrate sinonasal anatomy. Concha bullosa is
the pneumatization of the middle turbinate and one of the most common variations of
sinonasal anatomy. Concha bullosa may lead to narrowing or even complete blockage
of the entrance to the middle meatus.
Objectives: This work aimed to detect the relationship between concha bullosa and
incidence of sinusitis.
Subjective and methods: 100 subjects with age ranged from 20 to 50 years were
included in this study. They were divided into study and control groups. All subjects
were examined and C.T for all were performed.
Results: Significant difference was found between study and control groups as concha
bullosa was found in 80%of patients with chronic rhinosinusitis in contrary to 10% of
subjects not suffered from chronic rhinosinusitis.
Conclusion: concha bullosa may be one of the predisposing factors of chronic
rhinosinusitis and so surgical manipulation during FESS is important to avoid
recurrence of the disease.
