Three representative otolaryngological procedures–laryngeal surgery, endoscopic sinus surgery, and tympanoplasty–were selected based on their relevance to board certification requirements for otolaryngology specialists. The data were stratified by age, sex, and prefecture, and annual surgery counts as well as rates per 100,000 person-years were calculated. Trends over time were assessed using the Jonckheere-Terpstra trend test and Poisson regression models to estimate the annual risk ratios (RRs).

Tympanoplasty showed a smaller but significant decline, while the trends for endoscopic sinus surgery were minimal. Subgroup analyses indicated significant annual decreases among individuals aged 20–89 years, who comprised the majority of laryngeal surgery cases for males, females, and both sexes combined (RR range: 0.875–0.957; all <em>P</em> &lt; 0.0009).

The consistent decline in laryngeal surgery across major demographic groups suggests a systemic shift in clinical practice, rather than an isolated reduction in disease incidence.
