Prevalence and Determinants of Hearing Loss inPatients with Chronic Rhinosinusitis in a TertiaryHospital in Nigeria

Background: Chronic rhinosinusitis is a common otorhinolaryngologic condition that is often encountered in daily practice. Nasal obstruction is the most disturbing symptom in patients with chronic rhinosinusitis, which could predispose them to otologic pathologies. Aim: to assess the prevalence and determinants of hearing loss among patients with chronic rhinosinusitis in the Lagos State University Teaching Hospital. Method: an analytical cross-sectional study which was conducted among 256 patients diagnosed with chronic rhinosinusitis in Lagos State University Teaching Hospital. Participants’ audiological profiles were assessed by conducting Pure Tone Audiometry and Tympanometry. Data were analyzed with Statistical Package for Social Sciences version 26.0. Result: The participants aged 40-49 years constituted the largest age group (30.1%), and most of them were female (69.5%). The prevalence of hearing loss among the participants was 40.2%. There were reduced odds for hearing loss among participants aged 20-29 years (AOR= 0.043, 95% C.I. = 0.012- 0.157), 30-39 years (AOR= 0.042, 95% C.I. =0.010- 0.171) and 40-49 years (AOR= 0.075, 95% C.I. = 0.027- 0.209) compared with those age 60 years and above. Also there was reduced odds for hearing loss in male (AOR= 0.142, 95% C.I. = 0.057- 0.357), but those with facial pain had increased odds for hearing loss (AOR= 5.814, 95% C.I. =1.742- 19.231) and those with nasal polyp had increased odds for hearing loss (AOR= 2.134, 95% C.I. = 1.023- 4.451). Conclusion: in this study, there was a high prevalence of hearing loss among patients with chronic rhinosinusitis, and its determinants were age, gender, facial pain and nasal polyps
