Rhizolysis

INTRODUCTION: Glycerol rhizolysis, thermocoagulation and balloon compression are well established in the treatment of trigeminal neuralgia. Despite this, very few direct comparisons between these procedures have been published. We aimed to compare the outcome profile of these 3 percutaneous procedures in a single center over a long follow-up period. METHODS: Over 19 years, 393 procedures were performed on 210 patients with trigeminal neuralgia. Patient records and telephone follow-up were used to determine demographic and operative details and surgical outcomes...

BACKGROUND: Zygapophysial joint arthrosis is a pathology related with axial lumbar pain. The most accepted treatment, after failure of medical management, is the thermal denervation of the medial branch. Nonetheless, the placement of the heat probe remains a challenge to surgeons, even when using the fluoroscope. Using a variation of Shealy's and Bogduk's original techniques, which includes ablation of the medial branch and the nerves present in the joint capsule, we hypothesize that we can obtain similar outcomes to those found in the literature...

BACKGROUND: Despite >30 years of clinical use, the literature is still sparse when it comes to comparisons between percutaneous balloon compression (PBC) and percutaneous retrogasserian glycerol rhizolysis (PRGR) as treatments for trigeminal neuralgia. OBJECTIVE: To perform a retrospective cohort comparison between PBC and PRGR with regard to therapeutic effect, side effects, and complications. METHODS: Medical records and follow-up data from 124 primary PRGRs performed from 1986 to 2000 and 82 primary PBCs performed from 2000 to 2013 were reviewed...

INTRODUCTION: The objective of this study was to determine the long-term efficacy of percutaneous glycerol rhizolysis of the trigeminal ganglion for treating patients with trigeminal neuralgia and search for predictors associated with (long-term) benefit to improve patient selection. METHODS: A retrospective study in 60 consecutive patients treated with percutaneous glycerol rhizolysis of the trigeminal ganglion for trigeminal neuralgia. Charts were reviewed in combination with follow-up by questionnaire (n = 55, 92% response)...

INTRODUCTION: Trigeminal neuralgia is a sudden, unilateral, brief, stabbing, recurrent pain in the distribution of one or more branches of the fifth cranial nerve. Pain occurs in paroxysms, which can last from a few seconds to several minutes. The frequency of the paroxysms ranges from a few to hundreds of attacks a day. Periods of remission can last for months to years, but tend to shorten over time. The condition can impair activities of daily living and lead to depression. METHODS AND OUTCOMES: We conducted a systematic review and aimed to answer the following clinical question: What are the effects of ongoing treatments in people with trigeminal neuralgia? We searched: Medline, Embase, The Cochrane Library, and other important databases up to September 2013 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review)...

A 78-year-old man with combined trigeminal and glossopharyngeal neuralgia underwent glycerol rhizolysis of the trigeminal ganglion. The treatment led to the immediate relief of both neuralgias. We discuss the potential mechanism of this unexpected therapeutic effect with reference to the pathophysiology of trigeminal and glossopharyngeal neuralgia.

In the Australian medical and paramedical fields considerable interest has been stirred by percutaneous rhizolysis, the procedure introduced here by Dr. W. E. Skyrme Rees, M.B., Ch.B., F.R.C.S. The technique itself comes under intensive scrutiny. In theory the technique is a "percutaneous bilateral section of the posterior primary rami", either lumbar or cervical.

INTRODUCTION: We analyzed the etiopathogenetic, clinical, radiographic, and histopathologic aspects of keratocystic odontogenic tumors, particularly in association with dental anomalies of number, with the aim of providing useful information for their correct diagnosis, treatment, and prognosis within a multidisciplinary approach. CASE PRESENTATION: A 14-year-old Caucasian girl presented for observation of bilateral agenesis of the upper incisors, which was diagnosed by orthopantomography...

Percutaneous retrogasserian glycerol rhizolysis, introduced in 1981, has become established in the management of trigeminal neuralgia secondary to multiple sclerosis and pontine infarction. More recently, this technique was established as safe and reliable in managing pain originating from the zygapophyseal joints, with successful relief of pain in 67% of patients treated for lower back pain. In this article, we report a case of complete paralysis of lumbar paravertebral muscle function caused by severe multifidus degeneration after 3-level lumbar rhizolysis...

INTRODUCTION AND OBJECTIVES: The central odontogenic fibroma (COF) is a benign odontogenic tumour derived from the dental mesenchymal tissues. It is a rare tumour and only 70 cases of it have been published. Bearing in mind the rareness of the tumour, 8 new cases of central odontogenic fibroma have been found by analyzing the clinical, radiological and histopathological characteristics of COF. PATIENTS AND METHOD: A retrospective study was carried out on 3011 biopsies in the Service of Oral and Maxillofacial Surgery of the Dental Clinic of Barcelona University between January 1995 and March 2008...

BACKGROUND: Among the percutaneous procedures for the treatment of trigeminal neuralgia, percutaneous anhydrous glycerol rhizolysis (PRGR) and radiofrequency (RF) ablation of trigeminal neuralgia have stood the test of time. OBJECTIVE: A prospective study was conducted to compare PRGR and RF ablation techniques in patients with trigeminal neuralgia in terms of (1) efficacy of pain relief, (2) duration of pain relief and (3) side effects. METHODS: All patients presenting to our pain clinic for the first time for the treatment of trigeminal neuralgia were enrolled to receive either PRGR or RF ablation; the treatment was chosen by the patient...

Trigeminal neuralgia is a disorder associated with severe episodes of lancinating pain in the distribution of the trigeminal nerve. Previous reports indicate that 80-90% of cases are related to compression of the trigeminal nerve by an adjacent vessel. The majority of patients with trigeminal neuralgia eventually require surgical management in order to achieve remission of symptoms. Surgical options for management include ablative procedures (e.g., radiosurgery, percutaneous radiofrequency lesioning, balloon compression, glycerol rhizolysis, etc...

STUDY DESIGN: Case series. Prospective study. OBJECTIVE: This is a prospective study of a group of patients with chronic low back facet joint pain, meticulously selected using a combination of clinical history, examination, imaging tests, and lumbar facet joint block with a local anesthetic, aimed at assessing the efficacy of treatment with percutaneous rhizolysis in reducing pain and improving related disability. SUMMARY OF BACKGROUND DATA: Percutaneous radiofrequency facet joint denervation (rhizolysis) provides significant alleviation of pain and functional disability in patients with chronic low back pain of facet joint origin...

Trigeminal neuralgia (TN) is a neuropathic pain condition affecting the face. It has a significant impact on the quality of life and physical function of patients. Evidence suggests that the likely etiology is vascular compression of the trigeminal nerve leading to focal demyelination and aberrant neural discharge. Secondary causes such as multiple sclerosis or brain tumors can also produce symptomatic TN. Treatment must be individualized to each patient. Carbamazepine remains the drug of choice in the first-line treatment of TN...

OBJECT: Stereotactic radiosurgical rhizolysis using Gamma Knife surgery (GKS) is an increasingly popular treatment for medically refractory trigeminal neuralgia. Because of the increasing use of GKS for trigeminal neuralgia, clinicians are faced with the problem of choosing a subsequent treatment plan if GKS fails. This study was conducted to identify whether microvascular decompression (MVD) is a safe and effective treatment for patients who experience trigeminal neuralgia symptoms after GKS...

INTRODUCTION: From 1 August 1983 to 6 June 1992, 284 patients underwent decompression of the trigeminal root in the rear part of the skull as treatment for tic douloureux. According to preoperative diagnosis and intraoperative inspection, a space-occupying process was the cause of the typical neuralgia in 13 cases (4 meningiomas, 3 epidermoid tumours, 3 acoustic neuromas and 2 trigeminal neuromas). In 271 cases (95.4%) microsurgical vascular decompression according to Jannetta was carried out...
