Objective- The aim of the study is to determine the association of angulation of nasal septum with the severity of rhinosinusitis as measured by symptom score and visual analog score. Materials and methods- 50 patients who were diagnosed with rhinosinusitis and fullled the selection criteria were assessed for symptom score and VAS and measurement of angulation of nasal septum was performed through a coronal view of CT paranasal sinuses in bone window setting. Patients older than 18 years, diagnosed with rhinosinusit Inclusion criteria- is and carrying indications for CT scan of paranasal sinuses were included in the study. Patients with history of nasal Exclusion criteria trauma, septal surgery, septal haematoma ,septal perforation, concha bullosa, sinonasal tumors were excluded from the study. Results- The result obtained from one-way ANOVA test revealed a signicant association between category of severity of septal angulation and the symptom score of rhinosinusitis. Severity of nasal septum angulation may be signicantly asso Conclusion- ciated with severity of rhinosinusitis based on symptom score and VAS.these ndings could be used in management of patient with rhinosinusitis during functional endoscopic sinus surgery
