Differences in self-reported symptoms in patients with chronic odontogenic and non-odontogenic rhinosinusitis.

Purpose: To evaluate the possible differences in self-reported symptoms between patients with chronic odontogenic rhinosinusitis (CORS) and patients with chronic non-odontogenic rhinosinusitis (CnORS).

Materials And Methods: The study included 64 patients diagnosed with chronic rhinosinusitis according to EPOS guidelines. 32 patients had CORS, and the control group were 32 patients with CnORS. Patients were matched according to gender and age. All the patients underwent a CT scan evaluated by a radiologist, and were evaluated by an oral surgeon and otorhinolaryngologist before being assigned to one of the groups. The severity of the symptoms was assessed through questioners SNOT-22 (sino-nasal outcome test) and VAS (visual analogue scale) symptom score. Kolmogorov-Smirnov's, Fisher's and Mann-Whitney U test were used in the statistical analysis of the data.

Results: People with CORS show similar symptomatology on SNOT-22 score to patients with CnORS, with no significant statistical difference between any of the SNOT-22 symptoms. VAS symptom score showed that odontogenic group had a significantly higher score for fever (p = .004) and halitosis (p = .003).

Conclusion: Halitosis and fever might be the most important symptoms in differentiating between CORS and CnORS symptomatology. Better diagnostic tools, such as VAS symptom score might help medical professionals to be quicker at recognizing CORS specific symptomatology, and help them treat the disease as early and adequately as possible.
