Schwannomas (neurinoma, neurilemmoma) are benign slow-growing encapsulated tumours originating from well-differentiated myelin-producing Schwann cells or nerve fiber sheet cells at the glial-Schwann cell junction. Hypoglossal nerve schwannoma mostly develops in the intracranial and extra-cranial segment or in both intracranial and extra-cranial segment forming a dumbbell shape tumour. The peripheral hypoglossal schwannomas are very rare. We present a case of right hypoglossal nerve schwannoma in a 46-year-old female who presented with headache and neck pain since 2 weeks with deviation of tongue to right side since 1 week. Patient was investigated with Computed Tomography (CT) scan of head and Magnetic Resonance Imaging (MRI) of brain, which showed a dumb-bell shaped solid-cystic mass lesion with fluid-fluid level in right cerebello-pontine angle cistern.

Introduction: Obstructive sleep apnoea (OSA) is characterised by blood oxygen desaturations and sleep disruptions manifesting undesirable consequences. Existing treatments including oral appliances, positive airway pressure (PAP) therapy and surgically altering the anatomy of the pharynx have drawbacks including poor long-term adherence or often involving irreversible, invasive procedures. Bilateral hypoglossal nerve stimulation (HNS) is a new treatment for managing OSA, and this study is intended to determine whether an HNS system is a safe and effective treatment option for adults with OSA.

We report a case of a 39-year-old male patient who developed propofol-induced fasciculations during the induction of general anesthesia. The patient had a history of moderate obstructive sleep apnea and was intolerant to continuous positive airway pressure therapy. He subsequently underwent the insertion of a hypoglossal nerve stimulator as a viable surgical intervention.

Objective: This study was undertaken to test the following hypotheses in the Atp1a3 mouse (which carries the most common human ATP1A3 (the major subunit of the neuronal Na/K-adenosine triphosphatase [ATPase]) mutation, D801N): sudden unexpected death in epilepsy (SUDEP) occurs during seizures and is due to terminal apneas in some and due to lethal cardiac arrhythmias in others; and Atp1a3 mice have central cardiorespiratory dysregulation and abnormal respiratory drive.
Methods: Comparison was made of littermate wild-type and Atp1a3 groups using (1) simultaneous in vivo video-telemetry recordings of electroencephalogram, electrocardiogram, and breathing; (2) whole-body plethysmography; and (3) hypoglossal nerve recordings.
Results: In Atp1a3 mice, (1) SUDEP consistently occurred during seizures that were more severe than preterminal seizures; (2) seizure clustering occurred in periods preceding SUDEP; (3) slowing of breathing rate (BR) and heart rate was observed preictally before preterminal and terminal seizures; and (4) the sequence during terminal seizures was as follows: bradypnea with bradycardia/cardiac arrhythmias, then terminal apnea, followed by terminal cardiac arrhythmias.
Craniovertebral Junction Tuberculosis, a Rare Presentation With Hypoglossal and Facial Nerve Palsy: A Case Report.

Case: A 47-year-old man presented with neck pain, restricted neck movements, along with involvement of facial and hypoglossal nerve. On the basis of clinico-radiological correlation, the patient was diagnosed with craniovertebral junction tuberculosis and was started on antitubercular therapy (ATT). Failing the conservative trial, the patient was operated and occipitocervical fusion was done with bone grafting.

This is a case report of a rare hypoglossal nerve paresis after tonsillectomy in a healthy 29-year-old woman. While she made a full recovery, she experienced 6-8 weeks of dysphagia, dysarthria and had to be readmitted because of dehydration. As direct intraoperative trauma is unlikely due to the protected course of the nerve, we discuss possible mechanisms and suggest precautions to avoid similar neuropraxia - such as avoiding overinflation of the laryngeal mask airway, regularly relieving the tongue pressure and using careful manipulation of the tongue base if necessary.
