The course of the left recurrent laryngeal nerve through the chest brings it in close proximity with the heart and great cardiac vessels. Diseases of the heart and the great vessels are known to cause vocal cord paralysis, probably by mechanical injury to the recurrent laryngeal nerve. Pulmonary artery hypertension and dilation occur in up to 80% of patients with cystic fibrosis. We report a case of a 23-year-old woman with cystic fibrosis and left vocal cord paralysis. We believe that sudden pulmonary artery expansion produced recurrent laryngeal nerve injury and vocal cord paralysis. This is only the second association of unilateral vocal cord paralysis and cystic fibrosis in the medical literature. The pathophysiology of the cardiovocal syndrome is discussed.

ABSTRACT Thyroidectomy is a commonly performing surgery worldwide with known complications of recurrent laryngeal nerve injury (RLN) and vocal cord paralysis. To avoid RLN palsy, various methods of RLN identification have been defined, one of which is called as defining Beahrs’ triangle. How to cite this article Jain V.

Neural Monitoring

Introduction Intraoperative neural monitoring of the recurrent laryngeal nerve has been widely used to avoid nerve injury during thyroidectomy. We discuss the results of the change in surgical strategy after unilateral signal loss surgeries using intermittent intraoperative neural monitoring in a high-volume referral centre. Materials and methods Details of consecutive patients who underwent thyroidectomy with intermittent intraoperative neural monitoring between January 2014 and December 2017 were prospectively recorded and retrospectively reviewed. Loss of signal was defined as recurrent laryngeal nerve amplitude level lower than 100 μV during surgery. The rate of loss of signal and change in surgical strategy during the operation were evaluated. Results Loss of signal was detected in 25 (5.4%) of 456 patients for whom intermittent intraoperative neural monitoring was performed. Four patients had anatomic nerve disruption and surgery was completed by an experienced endocrine surgeon making use of intraoperative neural monitoring with continuous vagal stimulation. Staged thyroidectomy was performed on 16 patients with unilateral loss of signal in whom the nerves were intact visually. Postoperative vocal cord paralysis was encountered in 18 of 21 (85.7%) patients with loss of signal, and 16 of 18 (88.8%) were improved during the follow-up period. Patients’ voices were subjectively normal to the surgeon postoperatively in 9 of 21 (42.8%) patients who were found to have loss of signal with intact nerves. Conclusions Intraoperative neural monitoring can be used safely in thyroid surgery to avoid recurrent laryngeal nerve injury. It enables the surgeon to diagnose recurrent laryngeal nerve injury intraoperatively to estimate the postoperative nerve function and to modify the surgical strategy to avoid bilateral vocal cord paralysis.

Unilateral Vocal Cord Paralysis

Five cases of unilateral vocal cord paralysis/ paresis were diagnosed following extracorporeal membrane oxygenation for newborn respiratory failure. All were right sided and transient in nature. None of the five patients had other findings commonly associated with vocal cord palsy. The extracorporeal membrane oxygenation procedure requires surgical dissection in the carotid sheath on the right side of the neck, an area immediately adjacent to both the vagus and recurrent laryngeal nerve. It is speculated that vocal cord paralysis in these infants was acquired as a result of the extracorporeal membrane oxygenation cannulation. Although the vocal cord paralysis resolved in all cases, two patients had difficult courses after extracorporeal membrane oxygenation. Therefore, laryngoscopic examination should be considered for patients after extracorporeal membrane oxygenation.

Abstract Background Recurrent laryngeal nerve paralysis in esophagectomy is one of the most concerned complications. In recent years, intraoperative neurostimulation monitoring system (IONM) in thyroid surgery have been widespread for identification of recurrent laryngeal nerve and assessment of soundness. Therefore, IONM is often used during esophagectomy in Japan. In this study, we examined the efficacy of IONM in the patients undergoing esophagectomy. Methods Of 66 patients underwent esophagectomy since April 2015 until December 2017, IONM used in 27 patients in the surgery for the examination of recurrent nerve paralysis. We retrospectively reviewed these cases for intraoperative findings, neurostimulation monitoring findings and their outcomes. Results Of 27 patients, 25 were male and two were female, and the median age at operation was 66 years old. Although IONM was used in cervical lymph node dissection, there were no vocal cord responses in 5 patients (left side in 4 and right side in 1) with stimulation of the vagus nerve. Because all patients had no vocal cord paralysis due to stimulation of the cervical recurrent laryngeal nerve, it was diagnosed that there was the recurrent laryngeal nerve injury due to thoracic para recurrent nerve lymph node dissection. IONM was able to facilitate the identification and preservation of cervical recurrent nerve in all patients. Three out of 5 patients with no vocal cord response by IONM were confirmed recurrent laryngeal nerve paralysis in postoperative endoscope. In patients with vocal cord paralysis by IONM, it was possible to carefully performed postoperative management. On the other hand, in patients without paralysis, extubation on the operation day seemed possible without the concern for aspiration. Conclusion By using IONM in esophagectomy, we were able to evaluate the damage of the recurrent laryngeal nerve in real-time. Confirming the intraoperative recurrent nerve injuries is important for postoperative management or prediction of postoperative aspiration pneumonia. IONM in esophagectomy was useful not only in terms of surgical procedures but also in the evaluation of postoperative management. Disclosure All authors have declared no conflicts of interest.
