Schwannomas are usually benign, single, encapsulated, slow-growing tumours originating from cranial or spinal nerve sheaths. The vagus nerve involvement at the mediastinal inlet is very uncommon. For anatomical reasons, the resection of cervical and mediastinal schwannoma of the vagus nerve has a high risk of vocal fold paralysis. We describe the case of a 67-year-old female with a cervico-medi...

IT MAY BE CONCLUDED FROM THE RESULTS OBTAINED IN THESE EXPERIMENTS : 1. That stimulation of the right vagus nerve in the dog usually causes arrest of all the chambers of the heart. 2. That stimulation of the left vagus nerve exerts a moderate negative chronotropic effect on the auricles. 3. That stimulation of the left vagus nerve has a profound effect on the conduction of impulses over the aur...

The innate immune system protects against infection and tissue injury through the specialized organs of the reticuloendothelial system, including the lungs, liver, and spleen. The central nervous system regulates innate immune responses via the vagus nerve, a mechanism termed the cholinergic antiinflammatory pathway. Vagus nerve stimulation inhibits proinflammatory cytokine production by signal...

The present study evaluates the participation of the vagus nerve in pre-pubertal rats with unilateral ovariectomy on puberty onset, and on progesterone, testosterone and estradiol serum levels, and the compensatory responses of the ovary. Unilateral vagotomy did not modify the onset of puberty in unilaterally ovariectomized rats. Ovulation rates of animals with the left vagus nerve sectioned an...

Objective: Neuroimmune interplay is one of the basic elements that determine mucosal health and disease. Continuing discussion of the vagus nerve in maintenance of homeostasis of gastroduodenal area, we aim to revise immunomodulating effects of acetylcholine. Results: Vagus nerve plays a major role in gut mucosa immunity due to cytoprotective properties and modulation of leukocytes activity. St...

Total thyroidectomy was performed in a 53-year-old male, with Graves-Basedow's disease. At surgery, the vagus nerve was found to be located medially to the carotid artery associated with a non-recurrent laryngeal nerve arising directly from the cervical vagus: this association has never been described in the literature. These results indicate that a medial location of the vagus nerve may be con...

Policy [TOP] Vagus nerve stimulation may be considered medically necessary as a treatment of medically refractory seizures. Vagus nerve stimulation is considered investigational as a treatment of other conditions, including but not limited Non-implantable vagus nerve stimulation devices are considered investigational for all indications.

OBJECTIVES Vagal pathways in gastrointestinal tract are the most important pathways that regulate ischemia/reperfusion (I/R). Gastrointestinal tract is one of the important sources of melatonin production. The aim of this study was to investigate probable protective effect of the interaction between vagus nerve and melatonin after I/R. MATERIALS AND METHODS This study was performed in male ra...

INTRODUCTION Vagus nerve stimulators are devices used in the management of patients with drug-refractory epilepsy unsuitable for resective or disconnective surgery. Implanted usually by neurosurgeons, these devices are infrequently encountered by otolaryngologists. Despite significant anti-seizure efficacy, side effects related to laryngopharyngeal stimulation are not uncommon. CASE REPORT A ...
