Özet
Objectives This study examined the temporal and seasonal distribution of sudden sensorineural hearing loss admissions and audiogram types from 2015 to 2024 using seasonal-trend decomposition with locally estimated scatterplot smoothing. Methods A retrospective analysis included sudden sensorineural hearing loss patients admitted to a tertiary otorhinolaryngology clinic between January 2015 and December 2024. Demographics, admission dates and audiogram types were evaluated. Results Among 738 patients (mean age 45.7 ± 15.6 years; 58.4% male), admissions varied significantly across years, months and seasons, peaking from November to March. Winter admissions were highest, while autumn had the lowest. Seasonal-trend decomposition with locally estimated scatterplot smoothing confirmed recurring seasonal patterns. Although audiogram types showed no seasonal or pandemic association, their distribution differed significantly by month. Conclusion Sudden sensorineural hearing loss admissions demonstrate clear temporal and seasonal clustering, aligning with influenza-like illness peaks and suggesting a viral contribution. Monthly audiogram variations imply possible environmental influences.
