Abstract

Purpose: To determine the proportion, age and gender distribution of prevalence of septal degformities on Multislice Computed Tomography (MSCT) in patients with chronic rhinosinusitis. Subjects and methods: a retrospective study in 200 patients having chronic rhinosinusitis and undergoing sinus MSCT without intravenous contrast injection at Radiology Center-Hanoi Medical University Hospital from September 2020 to September 2022. MSCT scanning procedure from the frontal sinus to the end of the sphenoid sinus with 0.625mm thin layers, reconstructed in the coronal plane perpendicular to the hard palate and axial parallel to the hard palate. Results: The study included 200 patients with chronic rhinosinusitis. The average age of the patient group was 47.7±14.4, ranging from 8-77 years old with 103 patients (51,5%) male and 97 patients (48,5%) female. Among 200 patients, prevalence of septal degformities was present in 127 (63,5% with the rate of type I was 28 patients (28,22%), type II, III, IV, V, VI, VII was respectively 18 patients (18,14%), 20 patients (18.14%), 2 patients (2,1%), 15 patients (15,12%), 1 patients (1,1%), 17 patients (17,13%). The proportion of nasal septalwere crests was 24 patients (24,19%) and the number of patients with nasal septal bullosa was 2 patients (2.2%). The average age of the groups with and without prevalence of septal degformities was 48.1±13.7 and 47.1±15.7, the difference was not statistically significant with p>0.05. In the group with prevalence of septal degformities, the proportion of men and women were 49.5% (51 patients) and 50.5% (52 patients), respectively; the difference was not statistically significant with p> 0.05. Conclusion: prevalence of septal degformities were fairly common anatomical variant in patients with chronic rhinosinusitis. There was no difference between age and sex in patients with or without prevalence of septal degformities with chronic rhinosinusitis.
