Background: We present the experience in the treatment of trigeminal neuralgia (TN) during 15 years in one institute, evaluating epidemiological variables and clinical presentation, and comparing the results obtained with different treatments available.
Methods: A retrospective, descriptive study was carried out by reviewing cases diagnosed by the Neurology Service, such as TN, and treated by the Pain Medicine and Palliative Care Unit of the Insituto Nacional de Ciencias Médicas y Nutrición "Salvador Zubíran," from January 1, 1998 to December 31, 2003. Age, sex, type of neuralgia, anatomical site affected and intensity of pain were evaluated by means of the Analogue Visual Scale (AVS). The following treatments were evaluated (pharmacologic, surgical, and blockade of Gasser ganglion). Descriptive statistics, linear regression and bivariate correlation were used (statistical package SPSS).
Results: Fifty two cases were studied with a female predominance (2:1). Average age was 60 years. Clinical presentation most frequently was typical neuralgia (51.9%), right predominance (59.6%) and affected branch V2 (50%). In 88%, pharmacological treatment was used. The reduction of pain was 74% in all cases, with r-.765 for the pharmacological treatment, r-.715 in the blockade of the Gasser ganglion, and r-.901 for surgical treatment (p < 0.01).
Conclusions: In the experience of the INCMNSZ, treatment of choice in most cases of TN is pharmacological, with surgical treatment useful in cases where vascular alterations were identified.

Designing and clinical application of a 3D-printed personalized model of a radiofrequency needle guide with a maxillary fixator for puncture of the gasserian ganglion for trigeminal neuralgia treatment.
J Neurosurg

Objective: The purpose of this study was to present a newly designed 3D-printed personalized model (3D PPM) of a radiofrequency needle guide with a maxillary fixation for gasserian ganglion (GG) puncture.
Methods: Implementation of 3D CT-guided radiofrequency therapy of the GG with and without use of 3D PPM was analyzed. The following parameters were assessed: radiation time, dose area product, air kerma reference point, pain severity during the puncture needle insertion, prosopalgia regression degree (according to visual analog scale) and the severity of facial numbness (according to the Barrow Neurological Institute scale) in the early postoperative period, and postpuncture complications.
Aneurysm at the Trunk of the Medial-Type Persistent Trigeminal Artery Associated with Facial Pain : A Rare Case Report.

Persistent trigeminal artery (PTA) is the most common residual manifestation of persistent carotid-vertebrobasilar anastomosis, with the medial-type (intrasellar or sphenoidal) PTA being exceptionally rare. Aneurysms originating from the PTA trunk are not common. We present a unique case of an aneurysm located at the trunk of the medial-type PTA in a patient presenting with trigeminal neuralgia who successfully received endovascular treatment.

Department of Pharmacology, University of Arizona College of Medicine, Tucson, AZ, USA.
Background: Women with endometriosis are more likely to have migraine. The mechanisms underlying this co-morbidity are unknown. Prolactin, a neurohormone secreted and released into circulation from the anterior pituitary, can sensitize sensory neurons from female, but not male, rodents, monkeys and human donors.

Background: Bilateral trigeminal neuralgia secondary to multiple sclerosis is an extremely rare condition. When Gasserian ganglion block is performed, it is necessary to achieve reliable long-term analgesic effects while avoiding treatment-related complications.
Case Presentation: A 49-year-old male with multiple sclerosis exhibited persistent dull pain and paroxysmal electric shock-like pain in his bilateral maxillary molars and mandible.

Trigeminal neuralgia (TN) is a debilitating condition affecting the patients' life quality. New therapeutic approaches and novel drugs are required to treat TN. Trazodone being a serotonin antagonist and reuptake inhibitor (SARI) provides neuroprotection, however its role and underlying mechanism in TN or are not clear.
