BackgroundWe undertook collagen injection laryngoplasty to achieve arytenoid augmentation in patients with dysphagia and persistent aspiration following partial laryngectomy, and we evaluated the efficacy of arytenoid augmentation in aiding neoglottic closure and ensuring airway safety.MethodsTwo patients with persistent swallowing impairment after partial laryngectomy were studied. Swallowing was evaluated using fibre-optic endoscopy, and modified barium swallow study. Collagen was then injected into the arytenoid mucosa to achieve neoglottic competence.ResultsThe patients were followed up for up to two years. Both patients showed a marked improvement in neoglottic competence, as evaluated by fibre-optic and flexible endoscopy at three-month and one-year follow-up appointments.ConclusionArytenoid augmentation by injection laryngoplasty can be considered a safe and effective surgical tool for the treatment of dysphagia with persistent aspiration following partial laryngectomy.
