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...

OBJECTIVES: We investigated whether advanced age affects peri-operative outcomes after robotic-assisted pulmonary lobectomies. MATERIALS AND METHODS: We retrospectively analyzed patients who underwent robotic-assisted lobectomy by one surgeon over a 5-year period. Rates of postoperative complications were compared according to age group. Other outcomes, such as intraoperative complications, hospital length of stay (LOS), and in-hospital mortality, were also compared...

INTRODUCTION: Use of intra-operative neuro-monitoring (IONM) during high-risk thyroidectomy has been suggested to decrease the rate of recurrent laryngeal nerve (RLN) palsy. However, current evidences were mixed and there was no large-scale study concluding its benefit. We evaluated the role of IONM in reducing RLN palsy during high-risk thyroidectomy and identified which high-risk subgroup would be most benefited. METHODS: A systemic review was performed to identify studies comparing the use of IONM and visual identification of RLN alone (VA) during high-risk thyroidectomy, namely re-operation, thyroidectomy for malignancy, thyrotoxicosis or retrosternal goitre...

OBJECTIVES: The aim of the study was to stimulate the vagal and the recurrent laryngeal nerves during and after thyroidectomy or parathyroidectomy, to record muscle responses, interpret the electrophysiological modifications and identify prognostic factors for postoperative vocal fold mobility. PATIENTS AND METHODS: A prospective study monitored 151 vagal nerves and 144 recurrent laryngeal nerves in 114 patients. Seven patients (14 vagal nerves) underwent continuous monitoring via an automatic periodic stimulation (APS(®)) electrode...

BACKGROUND: Natural orifice transluminal endoscopic surgery developed for neck surgery become increasing popular. Herein, an innovative transoral endoscopic parathyroidectomy vestibular approach (TOEPVA) was developed for primary hyperparathyroidism (PHPT) and renal hyperparathyroidism (rHPT).

Injury to the recurrent laryngeal nerve (RLN) is a well known, though less frequent, complication of parathyroid surgery. In recent years, the use of intraoperative nerve monitoring (IONM) has gained popularity amongst surgeons when operating on thyroid gland; however, its utilization in parathyroid surgery is not established. This trend continues to rise, despite multiple studies documenting no statistically significant difference that IONM decreases the incidence of RLN injury. Most surgeons use this technology as an adjunct to visualization alone for identification of RLN...

PURPOSE: Taking into consideration that the aberrant right subclavian artery (ARSA) is the commonest congenital aortic arch anomaly (prevalence 0.16-4.4%), our goal was to investigate its incidence in Greeks, with respect to location, course, and relationship to trachea and esophagus. Gender dimorphism, coexisting neural, and vascular variations were also examined. The clinical impact and embryological background of the variation are discussed. METHODS: Two hundred and sixty-seven (126 male and 141 female) formalin-embalmed Greek cadavers (mean age 59 ± 13 years) were examined...

This study aimed to investigate the single-session complete ablation rate of ultrasound-guided percutaneous laser ablation (LA) for benign thyroid nodules. LA was performed in 90 patients with 118 benign thyroid nodules. Contrast-enhanced ultrasound (CEUS) was used to evaluate complete nodule ablation one day after ablation. Thyroid nodule volumes, thyroid functions, clinical symptoms and complications were evaluated 1, 3, 6, 12, and 18 months after ablation. Results showed that all benign thyroid nodules successfully underwent LA...

BACKGROUND: Quality of voice after immediate recurrent laryngeal nerve (RLN) reconstruction in thyroid cancers has not been thoroughly studied. METHODS: Thirteen patients with fixed vocal cords (fixed vocal cord group) and 8 patients with intact or impaired mobile vocal cords (mobile vocal cord group) who had immediate RLN reconstruction simultaneously with total thyroidectomy, and patients who had arytenoid adduction and thyroplasty for vocal cord paralysis caused by previous surgery (arytenoid adduction thyroplasty group) were enrolled in this study...

OBJECTIVES: The recurrent laryngeal nerve and its branches form a great variety of anastomoses. These nerve communications can alter the innervation patterns of the laryngeal muscles and can affect both the diagnosis and treatment of paralyzed vocal cords. The aim of this study was to assess the prevalence and anatomical characteristics of the laryngeal nerve connections, and to review their function and clinical significance.

BACKGROUND: The oncologic outcome of esophageal squamous cell carcinoma (ESCC) patients after robot-assisted thoracoscopic esophagectomy (RATE) with total mediastinal lymphadenectomy (ML) has not been reported. This study was performed to determine the oncologic outcome of RATE and the effectiveness of total ML for ESCC. METHODS: The 115 patients who underwent RATE without neoadjuvant therapy from 2006 to 2014 were reviewed. The efficacy index (EI) was calculated by multiplying the incidence of metastasis by the 3-year survival rate of the patients for each node station...

The definition of substernal goiter (SG) is based on variable criteria leading to a considerable variation in the reported incidence (from 0.2% to 45%). The peri- and postoperative complications are higher in total thyroidectomy (TT) for SG than that for cervical goiter. The aim of this study was to evaluate the preoperative risk factors associated with postoperative complications. From 2002 to 2014, 142 (8.5%; 98 women and 44 men) of the 1690 patients who underwent TT had a SG. We retrospectively evaluated the following parameters: sex, age, histology, pre- and retrovascular position, recurrence, and extension beyond the carina...

BACKGROUND: Open esophagectomy (OE) is associated with significant morbidity and mortality. Minimally invasive oesophagectomy (MIO) reduces complications in resectable esophageal cancer. The aim of this study is to explore the superiority of MIO in reducing complications and in-hospital mortality than OE. METHODS: MEDLINE, Embase, Science Citation Index, Wanfang, and Wiley Online Library were thoroughly searched. Odds ratio (OR)/weighted mean difference (WMD) with a 95% confidence interval (CI) was used to assess the strength of association...

While in many cases they are not directly visualized, awareness of the thoracic nerves and their courses at cross-sectional imaging is important for radiologists. An understanding of the normal function of each nerve is important, as many patients present with neurologic signs and symptoms that can be used to reinforce search patterns for disease and detection of supportive radiologic abnormalities. In the case of primary neoplasms, understanding the expected presence of a nerve in the location of a mass can enhance and improve the accuracy of differential diagnoses...

BACKGROUND: The non-recurrent laryngeal nerve (NRLN) is a rare but potentially serious anomaly that is commonly associated with the aberrant right subclavian artery (ARSA). It is easy to damage during surgical resection of esophageal cancer, leading to severe complications. METHODS: Preoperative enhanced thoracic computed tomography (CT) scans of 2697 patients with esophageal carcinoma treated in our hospital between January 2010 and December 2013 were examined...
