STUDY DESIGN: Cross-sectional analysis.

METHODS: This study evaluated personal payments concerning lecturing, consulting, and writing paid by 92 major pharmaceutical companies to all Japanese head and neck surgeons board-certified by the Japan Society for Head and Neck Surgery between 2016 and 2019.
