Objectives/hypothesis: The purpose of this study was to investigate the morphological and histological change of vocal folds (VFs) after steroid injection in a rabbit model.

Study Design: Prospective animal study.

Setting: Tertiary academic medical center.

Local steroid injection via the cricothyroid membrane in patients with a vocal nodule.
