Submucosal Thyroarytenoid Myectomy with Arytenoidectomy in Treating Bilateral Vocal Fold Immobility.
Article in The Laryngoscope, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveSurgery 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.
methodsCase-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.
resultsSuccessful 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.
conclusionSubmucosal 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.
