Vocal Fold Scar – New Classification Proposal

Background: There are several types of scars on the vocal folds, for multiple causes. Strobe videolaryngoscopy is the safest and most elucidative diagnostic method, as it evaluates the mobility of the vocal folds and the tissue analysis of the lesion. Treatments such as speech therapy, topical application and infiltration of substances, as well as surgeries are proposed alone or in combination. Objective: To present a new classification of vocal fold scars, taking into account structural changes within and outside the vocal fold boundaries. Method: To characterize scars that exceed the anatomical limits of the vocal folds, such as synechiae and granulomatous lesions, considered hypertrophic and exuberant. Classify the types of granulomas in terms of appearance and location. To classify the different types of synechiae resulting from reflux complication, iatrogenic surgical trauma, and post-radiotherapy. Compare intra-tissue scars with extra-tissue scars. Result and Conclusion: Proof of the efficacy of this didactic systematization with the use of videolaryngoscopy and microscopy associated with rigid endoscopy in the intraoperative period, with a better understanding of the disease and programming of the most appropriate therapeutic regimen.
