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)...

Hemidiaphragmatic paralysis is the most common adverse effect associated with interscalene block. In most cases, it resolves with the resolution of nerve blockade with only an estimated incidence of 0.048% persisting for longer duration. Occasionally, interscalene block is also associated with recurrent laryngeal nerve block and seldom with cranial nerve paresis. We present a case of delayed onset and prolonged hemidiaphragmatic paralysis that was associated with 3 cranial nerve deficits after interscalene nerve block for shoulder surgery performed under general anesthesia in the beach chair position...

BACKGROUND: In patients with papillary thyroid carcinoma (PTC), the role of total thyroidectomy (TT) versus that of thyroid lobectomy (TL) has been controversial. METHODS: This retrospective study was approved by our institutional review board, and the requirement to obtain informed consent was waived. In total, 173 patients with 1- to 5-cm stage cN0 and cM0 PTC tumors treated by curative surgery from 1994 to 2008 were evaluated. Clinicopathologic features and adverse events were compared between patients who underwent TT and those who underwent TL...

OBJECTIVE: Imaging plays a critical role in the evaluation of patients presenting with unilateral vocal fold paresis or paralysis of unknown etiology. In those with idiopathic unilateral vocal fold paralysis (iUVFP), there is no consensus regarding the need or timing of repeat imaging. This study seeks to establish the rate of delayed detection of alternate etiologies for these patients to determine if and when imaging should be repeated. METHODS: Retrospective chart review was conducted identifying patients at our institution with vocal fold movement impairment between 1998 and 2014...

The objective is to compare the consequences of routine visualization (RV) and the application of intermitted (I-IONM), standardized (S-IONM), and continuous monitoring (C-IONM) of recurrent laryngeal nerve (RLN) management. RV includes that 698 RLNs managed solely with visual identification. In a second period 777, RLNs were handled by the I-IONM. The third period 768 RLNs monitoring was performed according to the standards. C-IONM via VN stimulation included 626 RLNs. The following issues were analyzed and compared per each period study: RLN identification rate, branching detection, assessment of NRLN, intraoperative recognizable nerve damage, stage thyroidectomy rate, transient or definitive lesions, bilateral nerve palsy, and recovery time...
