Clinical features of chronic fungal rhinosinusitis in Korean geriatric and non-geriatric patients.

ABSTRACT

PURPOSE: Worldwide, the incidence of chronic fungal rhinosinusitis (CFRS) has increased. Although ageing leads to weakening of the immune system, which increases susceptibility to CFRS, the CFRS characteristics in geriatric patients are unclear. Therefore, we comparatively analysed the clinical characteristics of CFRS in geriatric and non-geriatric patients. METHODS: This retrospective analysis compared the demographics, rhinologic symptoms, multiple allergen simultaneous tests, olfactory function tests, paranasal sinus computed tomography findings, and outcomes of 131 patients with CFRS who underwent functional endoscopic sinus surgery and 131 enrolled patients were divided in geriatric (> 65 years) and non-geriatric (≤ 65 years) groups. RESULTS: Among the geriatric and non-geriatric participants (n = 65, 49.6% and n = 66, 50.4%, respectively), hypertension and diabetes mellitus were more common in the geriatric group. Demographics, including symptoms, showed no significant intergroup differences. Normosmia and hyposmia were significantly less prevalent, whereas phantosmia and parosmia were more prevalent in the geriatric group than in the non-geriatric group (p = 0.03 and p = 0.01, respectively). Sphenoidal sinus involvement was significantly higher in geriatric patients than in non-geriatric patients (p = 0.02). CONCLUSION: Based on greater sphenoidal sinus involvement, a deeper anatomical area is more vulnerable to fungal infection in the geriatric group than in the non-geriatric group. Increasing clinicians' awareness of CFRS in geriatric patients with olfactory dysfunction, including phantosmia and parosmia, is important for early intervention.
