OBJECTIVES/HYPOTHESIS: Cysts are benign vocal fold lesions typically divided into mucous retention or epidermoid subtypes. The conventional paradigm that the former are translucent and the latter opaque fails to encompass the heterogeneity of cyst appearance on laryngoscopy. This study aims to characterize the relationships between clinical cyst characteristics and histopathology. STUDY DESIGN: Retrospective cohort METHODS: Clinicodemographic data, videostroboscopy findings, and histopathology results were retrospectively reviewed for adults who underwent surgical excision of vocal fold cysts at our institution between 2006 and 2021. RESULTS: Diagnostic histopathologic material was available for 69 patients (age: 50.4 ± 15.1 years, 68.1% female). Clinically, most cysts were opaque (69.6%) and located at the vibratory margin (82.6%). 11.6% were infraglottic. Significant associations existed between cyst location and epithelial type, with infraglottic cysts and those at the superior surface more commonly exhibiting ductal (P = 0.003) and squamous (P = 0.002) epithelium, respectively. Cyst opacity did not correlate with histopathology (P = 0.415). Epidermoid cysts were more likely to exhibit clinical inflammation (P = 0.002).
