Objective: The study aimed (1) to evaluate the prevalence of sulcus vocalis (SV) coexisting with vocal fold polyp (SV-VFP), and (2) to determine the effect of their coexistence on voice quality. Study Design: This is a retrospective cohort study in a tertiary referral center. Methods: The medical records of all patients who underwent micro direct laryngoscopy due to VFPs between January 2013 and April 2015 were reviewed. Patients with SV-VFP were identified and data of their demographics, medical history, habits, preoperative and intraoperative laryngeal findings, and pre- and postoperative GRBAS (Grade, Roughness, Breathiness, Asthenia, Strain) score, and compared with the data of patients with solitary VFPs (S-VFPs). Results: Eighty-nine patients were diagnosed with VFPs, 14 (15.7%) of whom were diagnosed with SV-VFPs. Patients with SV-VFPs had significantly lower incidence of concurrent leukoplakia (P = 0.01), higher incidence of contralateral vocal fold lesions (P = 0.04), increased voice roughness score postoperatively (P = 0.01) on the GRBAS score, and had a lower rate of cigarette smoking (P = 0.02) compared with patients with S-VFPs. Conclusions: The possibility of a hidden SV should be considered when detecting VFPs, particularly in patients with contralateral vocal fold lesions and without cigarette smoking history. Because the group of patients with SV-VFP presented with unique features, we suspect that the coexistence of VFPs and SVs is not incidental and that SVs may contribute to the formation of VFPs, possibly by alternating glottic airflow.
