Introduction: Bilateral vocal folds' immobility is a challenge in laryngology. Multiple procedures have been proposed to improve breathing by statically enlarging the glottal airway, what also results in loss of voice and aspiration. We proposed a technique to enlarge the posterior glottis by rotating the arytenoids on its axis, imitating the function of the posterior cricoarytenoid muscle, with the objective of evaluating the results regarding decannulation, voice quality, and bronchoaspiration.

Purpose: With adequate indication and meticulous execution, endoscopic procedures can efficiently treat a subset of adult and pediatric benign laryngotracheal stenosis and obstructions, but these procedures are precise and very demanding. The difference between a successful and a failed surgery, with potentially debilitating side effects, resides in small details. The learning curve is long and very few centers worldwide have a sufficient case load making adequate training difficult. Read More

Department of Surgery, Division of Thoracic Surgery, Medical University of Vienna, Vienna, Austria.

Objectives: Bilateral vocal fold paralysis (VFP) is a severe complication after laryngotracheal (LT) surgery. The reduced glottic opening leads to significant respiratory distress immediately after the operation and requires the placement of a tracheostomy in most cases.

Objective: Treatment options for symptomatic unilateral vocal fold paralysis (VFP) include vocal fold augmentation, laryngeal framework surgery, and laryngeal reinnervation. Laryngeal reinnervation (LR) has been suggested to provide "tone" to the paralyzed VF. This implies a loss of tone as a result of denervation without reinnervation. Read More

The restoration of the functional competence of the larynx following bilateral laryngeal nerve damage and vocal fold paralysis is a serious challenge for the surgeon that has thus far no satisfactory solution. Physiological re-innervation that occurs naturally with time is non-selective and, in the majority of the cases, leads to synkinesis. Laryngeal pacing achieved with the application of the implantable microchips appears to be a promising approach. Read More
