Goal. To establish a reliable instrumental system for synchronized reactivation of a unilaterally paralyzed vocal fold and evaluate its functional feasibility. Methods. Unilateral vocal fold paralysis model was induced by destruction of the left recurrent laryngeal nerve (RLN) in anesthetized dogs. With a micro controller-based electronic system, electromyography (EMG) signals from cricothyroid (CT) muscle on the ipsilateral side were recorded and used to trigger pacing of paralyzed vocalis muscles. The dynamic movement of vocal folds was continuously monitored using an endoscope, and the opening and closing of the glottis were quantified with customized imaging processing software...

Charcot-Marie-Tooth type 4B1 (CMT4B1) is an autosomal recessive motor and sensory demyelinating neuropathy characterized by the association of early-onset neurological symptoms and typical histological findings. The natural history and the clinical variability of the disease are still poorly known, thus further clarification of the different phenotypes is needed. We report on the case of a Pakistani girl born to consanguineous parents harboring a novel mutation in the MTMR2 gene. When aged 18 months, reduced limb tone, muscle wasting associated with proximal and distal weakness prevalent in lower limbs, absence of tendon reflexes, hoarseness and inspiratory stridor were detected...

BACKGROUND: Based on randomized trials, carotid endarterectomy (CEA) is the standard procedure for patients with a 50-99% symptomatic carotid stenosis and carefully selected patients with an asymptomatic high-grade carotid stenosis. Carotid artery stenting (CAS) is a technical alternative for patients with a high surgical risk or difficult anatomic conditions (e.g., recurrent stenosis). This study aims to provide an overview of anatomic factors associated with a higher risk of CEA complications...

Damage to the recurrent laryngeal nerve often causes hoarseness, dyspnea, dysphagia, and sometimes asphyxia due to vocal cord paralysis which result in a reduction of quality of life. Brain-derived neurotrophic factor (BDNF) and glial cell line-derived neurotrophic factor (GDNF) play critical roles in peripheral nerve regeneration. However, methods for efficiently delivering these molecules are lacking, which limits their use in clinical applications. The present study reports an effective strategy for targeting BDNF and GDNF to laminin by fusing the N-terminal domains of these molecules with agrin (NtA)...

Vocal fold immobility is a relatively rare complication that can occur after tracheal intubation. Differential diagnoses include a rare clinical entity called unilateral vocal fold adductor paralysis in which only branches entering the thyroarytenoid and lateral cricoarytenoid muscles of the recurrent laryngeal nerve become paralyzed. Computed tomography and laryngeal electromyography are required to distinguish this condition from others such as cricoarytenoid dislocation/subluxation. Here, we describe two patients who developed vocal fold adductor paralysis after intubation...

OBJECTIVES/HYPOTHESIS: Intralaryngeal muscle synkinesis associated with unilateral vocal fold paralysis (UVFP) is thought to preserve thyroarytenoid-lateral cricoarytenoid muscle complex tone, resulting in a better voice despite the presence of vocal fold paralysis (VFP). This study compares voice handicap in patients with unilateral VFP (UVFP) with and without evidence of adductory synkinesis on laryngeal electromyography (LEMG). STUDY DESIGN: Retrospective review of LEMG data and Voice Handicap Index-10 (VHI-10) scores of patients diagnosed with permanent UVFP...

OBJECTIVE: Facial paralysis is a devastating condition leaving patients with a myriad of aesthetic and functional consequences. Muscle-nerve-muscle (MNM) neurotization is a reinnervation technique that involves implanting an autogenous nerve graft as a conduit between an innervated "donor" muscle and a denervated "recipient" muscle. We investigated the use of MNM reinnervation, alone or in combination with electrical stimulation (ES) and testosterone propionate (TP) in comparison to nerve reanastomosis (RE), on functional recovery following rat facial nerve injury...

OBJECTIVES/HYPOTHESIS: Vocal fold paresis and paralysis are common conditions. Treatment options include augmentation laryngoplasty and voice therapy. The optimal management for this condition is unclear. The objective of this study was to assess possible neuromuscular compensation mechanisms that could potentially be used in the treatment of vocal fold paresis and paralysis. STUDY DESIGN: In vivo canine model. METHODS: In an in vivo canine model, we examined three conditions: 1) unilateral right recurrent laryngeal nerve (RLN) paresis and paralysis, 2) unilateral superior laryngeal nerve (SLN) paralysis, and 3) unilateral vagal nerve paresis and paralysis...

BACKGROUND: Lymphadenectomy along the left recurrent laryngeal nerve (RLN) in esophageal cancer is important for disease control (1) but requires advanced dissection skills. We previously reported a reliable method (2) for lymphadenectomy along the left RLN during thoracoscopic esophagectomy in the prone position (TEP). The goal of this method is complete dissection of the lymph nodes along the left RLN in a safe manner. METHOD: This procedure is performed for all resectable thoracic esophageal cancers...

Introduction Tracheostomy is the commonest surgical procedure in intensive care units (ICUs). It not only provides stable airway and facilitates pulmonary toilet and ventilator weaning, but also decreases the direct laryngeal injury of endotracheal intubation, and improves patient comfort and daily living activity. Objective The objective of this study is to assess the incidence, indications, timing, complications (early and late), and the outcome of tracheostomy on patients in the intensive care units (ICU) at a university hospital in a developing country...

Since its introduction in 1988 by Dr. Archie Brain, the laryngeal mask airway (LMA) is being used with increasing frequency. Its ease of use has made it a very popular device in airway management and compared to endotracheal intubation it is less invasive. The use of LMA was on the rise, so has been the incidence of its related complications. We report severe unilateral vocal cord paralysis following the use of the supreme laryngeal mask (sLMA) in a patient with Sjögren's syndrome. In addition, we propose possible mechanisms of injury, review the existing case reports, and discuss our findings...

This study aimed to evaluate the feasibility and efficacy of minimal endoscope-assisted thyroidectomy (MEAT) through a retroauricular (RA) approach. Most of the thyroidectomy operative time was accounted for by direct visualization through the RA window, minimizing interference between surgical instruments. Endoscope use was minimized and limited to critical surgical aspects, including preservation of the recurrent laryngeal nerve and parathyroid glands. The recurrent laryngeal nerve was neuromonitored throughout the procedure...
