Title: Etiological classification of presbycusis in Turkish population according to audiogram configuration
Abstract: This study aims to classify age related hearing loss in Turkish population according to Schuknecht audiometric configurations for presbycusis and investigate the most common etiologies.A total of 1,134 patients (568 males, 566 females; mean age 70.5±7.7 years; range 55 to 80 years) with age related hearing loss were included in the study. Audiograms of patients were classified into three categories: high frequency steeply sloping (HFSS), flat, and high frequency gently sloping (HFGS). Speech discrimination scores were evaluated and compared.In the study population, HFSS audiogram configuration was the most frequently observed (48.5%), followed by HFGS configuration (26.9%), and flat configuration (24.5%), respectively. While HFSS audiogram configuration was statistically significantly more common in males, flat audiogram configuration was statistically significantly more common in females (p=0.0001). HFSS group mean air conduction threshold were statistically significantly higher than flat and HFGS groups (p=0.0001). No statistically significantly difference was detected in terms of speech discrimination scores between three groups (p=0.796).Results of this study suggest that, in Turkish population, while sensory presbycusis is more common in males, strial presbycusis is more common in females. No difference was detected in terms of the prevalence of cochlear presbycusis in males and females (p=0.0001).
