BACKGROUND: The management of solely intracanalicular acoustic neurinoma (iAN) includes observation, microsurgical resection and radiation therapy. Treatment goals are long-term tumor control, hearing preservation and concurrently low side-effects. Stereotactic radiosurgery (SRS) has evolved as an alternative first-line treatment for small AN. Here we report about the long-term follow-up of a unique cohort of patients with iAN after LINAC or Cyberknife® based SRS. METHODS: In this single center retrospective analysis, we included all patients with iAN who underwent single session LINAC or Cyberknife® based SRS between 1993 and 2015, and who had a minimum follow-up period of six weeks...

Facial paralysis can be a devastating condition, causing disfiguring facial droop, slurred speech, eye dryness, scarring and blindness. This study investigated the utility of closed-loop functional electric stimulation (FES) for reanimating paralyzed facial muscles in a quantitative rodent model. The right buccal and marginal mandibular branches of the rat facial nerve were transected for selective, unilateral paralysis of whisker muscles. Microwire electrodes were implanted bilaterally into the facial musculature for FES and electromyographic (EMG) recording...

Bilateral facial nerve palsy is a rare and sometimes difficult diagnosis. We describe a case of bilateral simultaneous facial nerve palsy associated with Epstein-Barr virus (EBV) infection in a 3-year-old boy. Several symptoms led to the diagnosis of EBV infection: the clinical situation (fever, stomachache, and throat infection), white blood cell count (5300/mm(3) with 70% lymphocyte count), seroconversion with EBV-specific antibodies, lymphocytic meningitis, and a positive blood EBV polymerase chain reaction (9...

BACKGROUND AND PURPOSE: Stapes surgery for otosclerosis can be challenging if access to the oval window niche is restricted. The aim of this study was to determine the accuracy of the computed tomographic (CT) scan in the evaluation of anatomical distances, and to analyze its reliability in predicting surgical technical difficulties. MATERIAL AND METHODS: A total of 96 patients (101 ears) were enrolled in a prospective study between 2012 and May 2015. During surgery, we evaluated the distance D1 between the stapes and the facial nerve, distance D2 between the promontory and the facial nerve after ablation of the superstructure, and the intraoperative discomfort of the surgeon...

OBJECTIVE In large vestibular schwannoma (VS) surgery, the facial nerve (FN) is at high risk of injury. Near-total resection has been advocated in the case of difficult facial nerve dissection, but the amount of residual tumor that should be left and when dissection should be stopped remain controversial factors. The objective of this study was to report FN outcome and radiological results in patients undergoing near-total VS resection guided by electromyographic supramaximal stimulation of the FN at the brainstem...

Classic Raymond syndrome presents with abducens nerve palsy on the ipsilateral side with contralateral hemiparesis and facial nerve paralysis. A 60-year gentleman presented with deviation of left angle of mouth and right sided weakness. Examination showed that he had left sided abducens nerve palsy, with contralateral central facial paralysis and paresis. MRI of brain confirmed left pontine infarct. These findings were consistent with classic Raymond syndrome. Till now, only a few cases have been reported worldwide, this being the first case reported in South Asia...

Background Many patients with mid-face or lower face craniofacial pain are diagnosed, based on accompanying signs and symptoms and features other than location, as either atypical migraines or atypical TACs. Distinguishing features of headache disorders as a cause of facial pain include the temporal pattern of pain, associated symptoms including light and sound sensitivity and nausea, cranial autonomic symptoms, and the lack of local triggering among others. Results An intraoral neurovascular pain has been observed, and was termed neurovascular orofacial pain (NVOP)...

Premise This review summarises the pain syndromes that overlap between headache and facial pain and overlap between pain and cranial nerve lesion. Problem These syndromes share two features in common. First, they show both cranial nerve impairment (e.g. palsy, autonomic dysfunction) and pain; second, they have inflammatory (and/or small vessel) processes as the underlying mechanism. A typical representative of these syndromes is recurrent painful ophthalmoplegic neuropathy, which was previously called ophthalmoplegic migraine and was regarded as a migraine subtype...

Here we describe the superficial appearance of the brain of the rarely studied tree pangolin. Phylogenetic analyses have placed the pangolins, order Pholidota, as a sister group to the order Carnivora. The majority of features visible on the surface of the tree pangolin brain, and its overall appearance can be described as typically mammalian. The pattern of sulci and gyri, while simple, appears very similar to that observed in carnivores. Two derived features of the Pholidota were observed, the first being the rostral decussation of the pyramidal tract, which instead of occurring at the spinomedullary junction, decussates at the level of the caudal pole of the facial nerve nucleus in the rostral medulla oblongata...

Schwannomas are benign encapsulated tumors arising from the sheaths of peripheral nerves. They present as slowly enlarging solitary lumps, which may cause neurological defects. Multiple schwannomas in non-neurofi bromatosis type 2 patients are extremely rare. We report a case of a 60-year-old female patient, without any family history of neurofibromatosis or schwannomatosis, presented with trigeminal neuralgia and progressive facial nerve palsy. Magnetic resonance imaging revealed the presence of acoustic schwannoma involving facial nerve and trigeminal schwannoma of the cisternal part of the nerve involving gasserian ganglion (Meckel’s cave)...
