We 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.
Two 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.
The 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.
Arytenoid augmentation by injection laryngoplasty can be considered a safe and effective surgical tool for the treatment of dysphagia with persistent aspiration following partial laryngectomy.
我们采用胶原蛋白注射喉成形术对部分喉切除术后出现吞咽困难和持续性误吸的患者进行杓状软骨增大术，并评估杓状软骨增大术在辅助新声门关闭和确保气道安全方面的疗效。
研究了两名部分喉切除术后持续存在吞咽障碍的患者。使用纤维内镜和改良钡餐吞咽造影评估吞咽情况。然后将胶原蛋白注射到杓状软骨黏膜中以实现新声门功能正常。
对患者进行了长达两年的随访。在三个月和一年的随访预约中，通过纤维内镜和软性内镜评估，两名患者的新声门功能均有显著改善。
注射喉成形术进行杓状软骨增大术可被视为治疗部分喉切除术后伴有持续性误吸的吞咽困难的一种安全有效的手术方法。
