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...

The most common cause of vocal cord paralysis (VCP) as a result of recurrent laryngeal nerve compression is malignant tumors. A benign and inflammatory causes of VCP is rarely reported in the literature, and in almost all reported cases it was a unilateral paralysis. We report a rare case of tuberculous mediastinal lymphadenopathy causing bilateral VCP in a young female patient.

BACKGROUND: The problem of recurrent laryngeal nerve (RLN) paralysis (RLNP) after radical esophagectomy remains unresolved. Several studies have confirmed that intraoperative nerve monitoring (IONM) of the RLN during thyroid surgery substantially decreases the incidence of RLN damage. This study tried to determine the feasibility and effectiveness of IONM of the RLN during thoracoscopic esophagectomy in the prone position for esophageal cancer. METHODS: All 108 patients who underwent prone esophagectomy at Tohoku University Hospital between July 2012 and March 2015 were included in this study...

Postoperative paralysis of the vocal cords resulting from intraoperative surgical injury of the recurrent laryngeal nerve is one of the most serious complications of elective thyroid surgery. The chance of injury is reduced by using intraoperative neuromonitoring (IONM). This educational report describes a case of IONM failure resulting from residual muscle relaxation that was restored by administration of sugammadex. It discusses possible pharmacology explanations and provides recommendations for how to prevent this situation in daily practice...

OBJECTIVES/HYPOTHESIS: Bilateral vocal cord paralysis in early childhood is a life-threatening condition, which often requires immediate intervention. One of the treatment options is a quick, reversible simple suture vocal cord lateralizing technique, whereby the arytenoid cartilage is directly lateralized to the normal abducted position. Considering pediatric laryngeal anatomy, a small endolaryngeal thread guide instrument was designed for precise suture insertion. STUDY DESIGN: New instrument validation...

CONCLUSIONS: The two scales reliably measure laryngeal edema and dysfunction in laryngeal cancer patients. The eight categories from these scales, and abnormal pharyngeal squeeze, can be used to form a new rating scale intended to help clinicians identify and circumvent swallowing complications after chemo-irradiation. OBJECTIVES: The objectives were to compare two laryngeal edema rating scales in laryngeal cancer patients and determine if post-radiation +/- chemotherapy edema predicts dependence on a feeding tube and/or tracheostomy...

OBJECTIVES: Speech signal processing techniques have provided several contributions to pathologic voice identification, in which healthy and unhealthy voice samples are evaluated. A less common approach is to identify laryngeal pathologies, for which the use of a noninvasive method for pathologic voice identification is an important step forward for preliminary diagnosis. In this study, a hierarchical classifier and a combination of systems are used to improve the accuracy of a three-class identification system (healthy, physiological larynx pathologies, and neuromuscular larynx pathologies)...
