OBJECTIVE: Microsurgery is the preferred treatment for large vestibular schwannomas (VSs). However, anatomical and functional preservation of the facial nerve (FN) remains a challenge during this surgery. The aim of this study was to determine whether it is beneficial to the preservation rates of the FN during microsurgical treatment of large VSs using intraoperative neurophysiological monitoring (IONM). METHODS: We retrospectively reviewed 53 patients with large VSs that underwent microsurgical resection via the retrosigmoid approach in our department during April 2009 to March 2016...

BACKGROUND: Nowadays, there is a general trend in vestibular schwannoma (VS) surgery favoring near-total or subtotal tumor resection (NTR/STR) with facial nerve (FN) function preservation rather than gross total resection (GTR) with high risk of FN damage. METHODS: The surgical technique of FN sparing in large VS includes patient-tailored image-guided craniotomy, continuous intraoperative neurophysiological monitoring (INM), intracapsular wide tumor debulking, and only final extracapsular dissection with FN course identification and brainstem decompression...

This article presents the development and experimental validation of a methodology to reduce the risk of thermal injury to the facial nerve during minimally invasive cochlear implantation surgery. The first step in this methodology is a pre-operative screening process, in which medical imaging is used to identify those patients that present a significant risk of developing high temperatures at the facial nerve during the drilling phase of the procedure. Such a risk is calculated based on the density of the bone along the drilling path and the thermal conductance between the drilling path and the nerve, and provides a criterion to exclude high-risk patients from receiving the minimally invasive procedure...

RATIONALE: Hereditary neuropathy with liability to pressure palsy (HNPP) is an episodic, multifocal neuropathy, with a typical clinical presentation of recurrent transient pressure palsies, which is induced by a PMP22 deletion. Another neuropathy caused by a PMP22 duplication is Charcot-Marie-Tooth disease type 1A (CMT1A). PMP22 is a gene coding a protein called peripheral myelin protein 22 (PMP22), which plays an essential role in the formation and maintenance of compact myelin. Coexistence of type 2 diabetes mellitus (T2DM) and CMT1A has been reported in many work, however HNPP patients with T2DM are rare, and comorbidity of HNPP and psoriasis has not been reported previously...

Objectives.:  Percutaneous radiofrequency ablation (RFA) of the gasserian ganglion through the foramen ovale and the glossopharyngeal nerve at the jugular foramen is a classical approach to treating trigeminal neuralgia (TN) and glossopharyngeal neuralgia (GPN), respectively. However, it can be technically challenging with serious complications. We have thus developed a novel technique utilizing C-arm and computerized tomography (CT) guidance to block TN and GPN. Our goals were to describe a three-dimensional image-based technique to improve patient comfort and to decrease procedural time associated with needle guidance...

BACKGROUND: Trigemino-cardiac reflex is a physiologic response of the body to pressure effects in the region of distribution of the trigeminal nerve. Oral and maxillofacial surgical procedures can induce the development of this reflex, which leads to significant changes in the heart rate and sinus rhythms. This study intends to evaluate the effects of this reflex in patients with facial fractures and its subsequent management. PATIENTS AND METHODS: A total of thirty-seven patients with facial fractures who reported to the Department of Oral and Maxillofacial Surgery at Basaveswar Teaching and General Hospital, Gulbarga during a period from July 2015-March 2016 were considered for the study...

Hemifacial microsomia (HFM) is a rare, multisystemic congenital disease with estimated frequency of 1/26370 births in Europe. Most cases are sporadic and caused by unilateral abnormal morphogenesis of the first and second pharyngeal arches. The aim of this study is to define the types and frequency of maxillofacial and systemic malformations in HFM patients. This is a case series study of patients with HFM evaluated at a single institution. Data were acquired through history, physical examination, photographs, diagnostic radiology, and laboratory and analyzed by the FileMakerPro database on 95 patients (54F; 41M) of which 89 met the inclusion criteria...

BACKGROUND: Microvascular decompression (MVD) of the facial nerve monitored intraoperatively by abnormal muscle response (AMR) activity is a common treatment for hemifacial spasm. AMR frequently persists after MVD, however, for which electromyography (EMG)-guided nerve combing sometimes is recommended. Because no research regarding the success of EMG-guided nerve combing has been published, we compared the effectiveness of nerve combing after MVD with simple MVD in cases including persistent AMR...

Bispectral index is an accepted depth of anaesthesia monitor for guiding intraoperative hypnotic agent administration. Frontalis EMG displayed on BIS monitor may increase due to twitching of frontalis muscle. EMG increases are also known to cause artefactual increases in BIS values. We report a case of artefactual increase of EMG and subsequently BIS values, due to electrical artefact from cranial nerve stimulator being used to identify the facial nerve. An explanation of the effect of stimulator signal on BIS EMG and BIS values has been provided...

BACKGROUND: Microvascular decompression (MVD) is the most useful treatment for hemifacial spasm (HFS). During MVD surgery, traditional abnormal muscle response (tAMR) is widely used to monitor success in decompressing the facial nerve. Dual AMR (dAMR) is a new monitoring method used during MVD for HFS. We compared the sensitivities and reliabilities of tAMR and dAMR. METHODS: We performed a retrospective study of 1301 cases of HFS treated using MVD between January 2014 and March 2016...
