BACKGROUND: Trigeminal neuralgia (TN) caused solely by venous compression is uncommon. An appropriate vein management protocol for microvascular decompression (MVD) has not been established. We evaluated the management of veins for TN solely due to venous involvement. METHOD: We analyzed 31 patients with TN in whom only veins were manipulated during MVD. The culprit veins smaller in diameter than the vein of the cerebellopontine fissure (VCPF) were coagulated and divided in 20 patients (divided group), while transposition was performed for larger veins in the remaining 11 patients (non-divided group)...

This paper describes two patients with squamous cell carcinoma (SCC) of the periocular and periorbital skin who presented with trigeminal neuralgia. Both patients had previous cutaneous SCC of the scalp treated successfully with surgical resection but later presented with neuro-ophthalmic findings suggesting perineural invasion (PNI) of SCC. PNI of SCC in the periocular skin or orbit can lead to devastating effects if malignant cells seed into the orbit and adjacent cranial nerves as our two patients developed an orbital apex syndrome...

INTRODUCTION: Trigeminal neuralgia is an agonising orofacial pain affecting unilaterally the distribution of the trigeminal nerve and it usually occurs in the middle and older age groups. Carbamazepine which is an anti-neuralgic as well as an anti-convulsant medication is the first line drug for treatment of trigeminal neuralgia. It is commonly taken as one tablet (200 mg) three times a day. MATERIALS AND METHODS: This is an observational study carried out from April to September 2014 to determine how Muslim patients on carbamazepine treatment for trigeminal neuralgia cope with their neuralgic pain...

BACKGROUND Systemic lupus erythematosus (SLE) is a multisystem autoimmune disorder of unknown etiology which can present at any age with symptoms of mucocutaneous, musculoskeletal, renal, central nervous system, and nonspecific clinical pictures making the disease a "master of mimicry". CASE REPORT A 53-year-old female, who was recently diagnosed with SLE, presented with right-sided sharp and electric shock-like facial pain starting at the side of her right nostril and traveling down the naso-labial fold and then back to the angle of the jaw, mostly in the region of V2-V3 distribution with no radiation beyond trigeminal distribution...

Introduction Trigeminal neuralgia (TN) is characterized by touch-evoked unilateral brief shock-like paroxysmal pain in one or more divisions of the trigeminal nerve. In addition to the paroxysmal pain, some patients also have continuous pain. TN is divided into classical TN (CTN) and secondary TN (STN). Etiology and pathophysiology Demyelination of primary sensory trigeminal afferents in the root entry zone is the predominant pathophysiological mechanism. Most likely, demyelination paves the way for generation of ectopic impulses and ephaptic crosstalk...

BACKGROUND: Microvascular decompression (MVD) is the most effective and non-ablative treatment for trigeminal neuralgia (TN). However, it is not possible when neurovascular compression (NVC) is absent. Neurocombing is a possible treatment option for TN patients without NVC. AIM: To evaluate and describe the clinical outcome of neurocombing for the treatment of TN when NVC was absent. METHODS: We retrospectively reviewed the clinical data of the 37 patients of Type 1 TN without NVC who underwent neurocombing in our department between January 2013 and November 2014...

PURPOSE: SRS is an effective non-invasive alternative treatment modality with minimal-toxicity used to treat patients with medically/surgically refractory trigeminal neuralgia root(TNR) or those who may not tolerate surgical intervention. We present our linac-based SRS procedure for TNR treatment and simultaneously report our clinical outcomes. METHODS: Twenty-eight TNR-patients treated with frame-based SRS at our institution (2009-2015) with a single-fraction point-dose of 60-80Gy to TNR were included in this IRB-approved study...

PURPOSE: Occipital neuralgia is a condition wherein pain is transmitted by the occipital nerves. Non-invasive therapies generally alleviate symptoms; however, persistent or recurring pain may require invasive procedures. Repeated invasive procedures upon failure are considered higher risk and are often contraindicated due to compounding inherent risk. SRS has not been explored as a treatment option largely due to the extracranial nature of the target (as opposed to the similar, more established trigeminal neuralgia), but advances in linear-accelerator frameless-based SRS now present an opportunity to evaluate the novel potential of this modality for this application...

PURPOSE: Focal radiosurgery is a common treatment modality for trigeminal neuralgia (TN), a neuropathic facial pain condition. Assessment of treatment effectiveness is primarily clinical, given the paucity of investigational tools to assess trigeminal nerve changes. The efficiency of radiosurgery is related to its highly precise targeting. We assessed clinically the targeting accuracy of radiosurgery with Gamma knife. We hypothesized that trigeminal tractography provides more information than 2D-MR imaging, allowing detection of unique, focal changes in the target area after radiosurgery...

Intracranial ganglioneuromas are very rare benign tumors of neural crest origin and generally arise from peripheral nervous system or adrenal glands. Very few cases of intracranial ganglioneuroma arising from the trigeminal nerve have been reported in literature so far. Out of those reported, all have been recognized in Eastern Asia. We report a rare case of trigeminal ganglioneuroma in a 52-year-old Caucasian male presenting with right trigeminal neuralgia.

INTRODUCTION: Schwannomas are benign tumours that are relatively common in the head, however the involvement of the sinunasal region is rare and there are only 5 cases reported in the maxilla in current literature, representing less than 1% of bone tumours. CLINICAL CASE: We report the case of a woman with a right maxillary schwannoma who underwent a complete resection of the lesion. Emphasis is placed on the rarity of the lesion in terms of its location and includes a review of clinical behaviour, diagnosis and current treatment options...

Several neurosurgical procedures, including rhizotomy for the management of trigeminal neuralgia, cannulate the foramen ovale (FO) to access intracranial structures. Cannulation procedures, including those utilizing neuronavigational technology, are occasionally complicated by anatomical variation of the FO, sometimes resulting in miscannulation and subsequent adverse events. The FO, while commonly thought of as oval-shaped, has also been described as "almond," "banana," "D shape," "pear," and "triangular." Because of the importance of the FO in neurosurgical procedures and the misunderstanding of FO shape, the aim of this study is to objectively describe the shape of the FO and its most likely shape variation...

Therapeutic strategy is controversial and not yet uniform for patients with trigeminal neuralgia (TN) and persistent or recurrent facial pain after microvascular decompression, percutaneous radiofrequency thermocoagulation (PRT), or Gamma Knife surgery. The outcomes and risks of PRT for these patients are not clearly understood. The authors performed a retrospective study of 84 patients with persistent or recurrent TN after surgery who then underwent PRT between 2007 and 2013. Data were obtained with chart review and telephone interviews...

The debilitating pain of trigeminal neuralgia often necessitates neurosurgical intervention via percutaneous transovale cannulation. While most percutaneous treatments of trigeminal neuralgia are successful, severe adverse events resulting from failure to properly cannulate the foramen ovale (FO) have been reported. With regard to specific targeting of particular trigeminal divisions (ie, V1, V2, V3, and combinations thereof), operative techniques have been described; however, these descriptions have not included specific angulation data...

Primary trigeminal neuralgia (TN) may occasionally occur in absence of neurovascular compression. A mechanism other than nerovascular compression may play a role in TN. High-resolution computed tomographies (CTs) of 21 consecutive TN patients without vascular compression during surgery and 30 healthy volunteers were retrospectively performed. Measuring parameters (length, width, and aspect ratio) were obtained in the axial plane for foramen ovale, and in the reconstructed coronal plane for foramen rotundum on both sides in each subject...

Trigeminal neuralgia is characterized by facial pain that may be sudden, intense, and recurrent. Our aim was to investigate microstructural tissue changes of the trigeminal nerve in patients with trigeminal neuralgia resulting from neurovascular compression by diffusion tensor imaging, and to test the predictive value of diffusion tensor imaging for determining outcomes after radiofrequency rhizotomy. Forty-three patients with trigeminal neuralgia were recruited, and diffusion tensor imaging was performed before radiofrequency rhizotomy...
