Vocal Fold Polyps: A Scoping Review

This review aims to summarize the current understanding of vocal fold polyp etiology, pathophysiology, and prognosis, as well as recent developments in management. Scoping literature review. OVID Medline, PubMed, Google Scholar, Conference Papers Index, and Cochrane Library were searched for publications within the last 5 years using terms including “vocal,” “cord,” “fold,” and “polyp.” All abstracts were screened. Relevant studies pertaining to the etiology, pathophysiology, diagnosis, management, and prognosis of vocal fold polyps (VFPs) were included for review. Eight-hundred and sixty-five citations resulted from database review. Seven-hundred and thirty citations remained after the exclusion of duplicates. One hundred and ninety-three papers underwent abstract review, with 73 citations undergoing full-text review. Fifty-nine papers were included in the review. VFPs are one of the most common subtypes of benign vocal fold lesions. Phonotrauma contributes significantly to the development of these lesions, with laryngopharyngeal reflux and smoking also contributing. Correct diagnosis relies on a careful history, stroboscopy, response to voice therapy, and, in some cases, intraoperative findings. Phonosurgery is a definitive means of treatment, though more recently, in-office procedures have demonstrated efficacy and are potentially less costly and less invasive treatment options. Treatment modalities can be tailored based on the type and size of the lesion, the patient’s vocal needs, medical comorbidities, and initial response to voice therapy. Voice specialists can anticipate greater emphasis placed on minimally invasive office-based procedures for the management of vocal pathology.
