Development of and psychometric testing for the Brief Pain Inventory-Facial in patients with facial pain syndromes.
Journal of neurosurgery, 2010Co-Authors: John T Farrar, John Y. K. Lee, H. Isaac Chen, Christopher Urban, Anahita Hojat, Ephraim W. Church, Sharon X. XieAbstract:Object Outcomes in clinical trials on Trigeminal pain therapies require instruments with demonstrated reliability and validity. The authors evaluated the Brief Pain Inventory (BPI) in its existing form plus an additional 7 facial-specific items in patients referred to a single neurosurgeon for a diagnosis of facial pain. The complete 18-item instrument is referred to as the BPI-Facial. Methods This study was a cross-sectional analysis of patients who completed the BPI-Facial. The diagnosis of classic versus Atypical Trigeminal Neuralgia (TN) was made before analyzing the questionnaire results. A hypothesis-driven factor analysis was used to determine the principal components of the questionnaire. Item reliability and questionnaire validity were tested for these specific constructs. Results Data from 156 patients were analyzed, including 114 patients (73%) with classic and 42 (27%) with Atypical TN. Using orthomax rotation factor analysis, 3 factors with an eigenvalue > 1.0 were identified—pain intensity, ...

pulsed radiofrequency v2 treatment and intranasal sphenopalatine ganglion block a combination therapy for Atypical Trigeminal Neuralgia
Pain Practice, 2010Co-Authors: Michelle Nguyen, Denise WilkesAbstract:: Trigeminal Neuralgia (TN) is a chronic condition affecting the fifth cranial nerve and resulting in sporadic intense burning and shock-like pain lasting for seconds to minutes that can be incapacitating to patients. Atypical TN includes additional features such as continuous pain and sensory disturbances in the area innervated by one or more branches of the Trigeminal nerve. Documented cases of TN have dated back to the 18th century. Today, there are roughly 140,000 people suffering with this condition in the U.S.A. Conventional treatments for this disorder include medical management with nonconvulsants such as carbamazepine, which decrease the nerves response to peripheral stimulation. These agents have good initial pain relief, but relief rates fall off dramatically over the long-term. Recently, methadone has shown promise as a pharmacologic adjunct to patients with intractable neuropathic noncancer pain, including patients suffering from TN. Cases refractory to medical management can be treated with surgical microdecompression or minimally invasive procedures such as radiofrequency (RF) treatment. Pulsed RF (PRF) is a method gaining interest as it is delivered in pulses, allowing adequate time for dissipation of heat and energy resulting in less damage to surrounding structures. This case report describes the successful treatment of Atypical V2 TN refractive to medical management requiring PRF treatment, a sphenopalatine block series, and low-dose methadone.

predictors of outcome in surgically managed patients with typical and Atypical Trigeminal Neuralgia comparison of results following microvascular decompression
Journal of Neurosurgery, 2002Co-Authors: Elizabeth C Tylerkabara, Amin B Kassam, Michael H Horowitz, Louise Urgo, Constantinos G Hadjipanayis, Elad I Levy, Yuefang ChangAbstract:Object. Microvascular decompression (MVD) has become one of the primary treatments for typical Trigeminal Neuralgia (TN). Not all patients with facial pain, however, suffer from the typical form of this disease; many patients who present for surgical intervention actually have Atypical TN. The authors compare the results of MVD performed for typical and Atypical TN at their institution. Methods. The results of 2675 MVDs in 2264 patients were reviewed using information obtained from the department database. The authors examined immediate postoperative relief in 2003 patients with typical and 672 with Atypical TN, and long-term follow-up results in patients for whom more than 5 years of follow-up data were available (969 with typical and 219 with Atypical TN). Outcomes were divided into three categories: excellent, pain relief without medication; good, mild or intermittent pain controlled with low-dose medication; and poor, no or poor pain relief with large amounts of medication. The results for typical and...
