European consensus on endoscopic surgery for bilateral vocal fold immobility: classification and nomenclature.
Practice Guideline
There are inconsistencies in how different endoscopic procedures to manage Bilateral Vocal Fold Immobility (BVFI) have been described in the literature. This limits our ability to compare functional outcomes. There is no unifying international terminology available that precisely describes the anatomical boundaries and extent of the different types of treatment. A pan-European consensus regarding terminology of different endoscopic surgical procedures to manage BVFI in adults was developed./r/nThirty-one expert laryngologists and phoniatricians of the European Laryngological Society (ELS) or Union of the European Phoniatricians (UEP), participated in a modified Delphi process. They voted on an initial series of 13 proposed statements, including graphical visualization of different endoscopic surgical techniques for BVFI. Statements reaching > 70% of agreement in the first voting round were accepted. In the second voting round, eight revised and newly proposed statements were accepted with an increased threshold of > 80%./r/nFourteen statements were anonymously validated through two voting rounds. The following categories of endoscopic arytenoid and vocal fold surgery were defined: total arytenoidectomy, partial arytenoidectomy (subclassified into subtotal, anteromedial, posteromedial and superomedial), posterior cordectomy (subclassified into ligamental, transmuscular and ventriculocordectomy) and transverse cordotomy (subclassified into posterior cordotomy and ventriculocordotomy). The suffixes ‘with mucosal preservation’, ‘with laterofixation’ and ‘combined procedure’ were defined too./r/nThis ELS-UEP consensus on endoscopic arytenoid and vocal fold surgery for BVFI provides a practical nomenclature and classification to improve reporting in literature and clinical practice and to allow comparison of functional outcomes.
