Abstract
Objective: Surgery for bilateral vocal fold immobility (BVFI) aims to establish a patent airway while maintaining voice and swallow function, a unique dilemma. Current techniques display unfavorable healing vectors, and exposed endolaryngeal tissue results in substantial airway granulation requiring postoperative care. We present a novel technique to improve glottic airway patency by preserving laryngeal mucosal lining and harnessing lateral retraction of glottic tissue to reduce revisions for granulation tissue and laryngeal scar.
Methods: Case-series analysis was performed on eight BVFI patients who underwent submucosal thyroarytenoid myectomy with arytenoidectomy for treatment from 2011 to 2021. Patient medical comorbidities and BVFI etiology were reviewed. Decannulation rates, revision procedures, requirement of emergency services, and pre- and postoperative status were assessed by laryngology and speech-language pathology using the following metrics: VHI, DI, Modified Medical Research Council (MMRC), GRBAS, jitter percentage, shimmer percentage, pitch range, maximum phonation time, and dysphonia severity index, and diet type. Pre- and postoperative distal-chip flexible laryngoscopy with stroboscopy was performed. Outcome measures were assessed using paired Student's t-test of pre- and postoperative categorical variables.
Results: Successful decannulation was achieved in all (four of eight) patients with previous tracheostomy. All patients reported improved respiratory symptoms without tracheotomy. There was no difference in long-term voice outcomes. All patients tolerated a mechanical soft or regular diet, without new or worsened dysphagia.
Conclusion: Submucosal thyroarytenoid myomectomy with arytenoidectomy represents an effective BVFI treatment, through utilizing natural vectors of scarring, preservation of endolaryngeal mucosa, and preservation of the superficial lamina propria and the vocal ligament.
期刊介绍：
The Laryngoscope has been the leading source of information on advances in the diagnosis and treatment of head and neck disorders since 1890. The Laryngoscope is the first choice among otolaryngologists for publication of their important findings and techniques. Each monthly issue of The Laryngoscope features peer-reviewed medical, clinical, and research contributions in general otolaryngology, allergy/rhinology, otology/neurotology, laryngology/bronchoesophagology, head and neck surgery, sleep medicine, pediatric otolaryngology, facial plastics and reconstructive surgery, oncology, and communicative disorders. Contributions include papers and posters presented at the Annual and Section Meetings of the Triological Society, as well as independent papers, "How I Do It", "Triological Best Practice" articles, and contemporary reviews. Theses authored by the Triological Society’s new Fellows as well as papers presented at meetings of the American Laryngological Association are published in The Laryngoscope.
