Therapeutic Approaches for the Management of Trigeminal Autonomic Cephalalgias.

ABSTRACT: Trigeminal autonomic cephalalgia (TAC) encompasses 4 unique primary headache types: cluster headache, paroxysmal hemicrania, hemicrania continua, and short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing and short-lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms. They are grouped on the basis of their shared clinical features of unilateral headache of varying durations and ipsilateral cranial autonomic symptoms. The shared clinical features reflect the underlying activation of the trigeminal-autonomic reflex. The treatment for TACs has been limited and not specific to the underlying pathogenesis. There is a proportion of patients who are refractory or intolerant to the current standard medical treatment. From instrumental bench work research and neuroimaging studies, there are new therapeutic targets identified in TACs. Treatment has become more targeted and aimed towards the pathogenesis of the conditions. The therapeutic targets range from the macroscopic and structural level down to the molecular and receptor level. The structural targets for surgical and noninvasive neuromodulation include central neuromodulation targets: posterior hypothalamus and, high cervical nerves, and peripheral neuromodulation targets: occipital nerves, sphenopalatine ganglion, and vagus nerve. In this review, we will also discuss the neuropeptide and molecular targets, in particular, calcitonin gene-related peptide, somatostatin, transient receptor potential vanilloid-1 receptor, nitric oxide, melatonin, orexin, pituitary adenylate cyclase-activating polypeptide, and glutamate.

Project description:Trigeminal schwannomas (TS), though the second most common intracranial schwannomas, represent only 0.8 to 8% of all Schwannomas. Advancement in imaging and microsurgical techniques has led to a remarkable improvement in the outcome of these benign tumors. Multicompartmental TS, though extensive, have an excellent outcome after surgery. In this article, we present our experience in the management of multicompartmental TS (types middle/posterior [MP], middle/extracranial [ME], and middle/posterior and extracranial [MPE]) and outcome in this rather uncommon group of tumors. This retrospective study included all the cases of multicompartmental TS operated at our institute from 1999 to 2009. The medical data were analyzed retrospectively. The demographic profile, clinical features, radiological findings, management strategies, postoperative complications, length of hospitalization, and outcome were noted. Follow-up data were collected from outpatient department records. The range and average duration of follow-up were noted. There were a total of 43 patients with TS operated over this period. Among them, 4 were type B, 5 type C, 11 type D, 18 type E, and 5 type F. The study included 26 patients (4 type B, 18 type E, and 4 type B). A variety of approaches were used to approach the tumor. Of 26, 23 patients had a gross total or near-total excision while 2 patients were lost to follow-up. Among the three patients who had a near-total excision and follow-up magnetic resonance imaging showed a small residual tumor, two are on close follow-up with no increase in the size of the tumor over a follow-up period of 3 years, the other patient is a 5-year-old boy who is too young for radiosurgery and is on follow-up. There was no mortality while four patients have had fresh permanent postoperative deficits. Multicompartmental TS are a rare, complex but eminently treatable group of tumors. A variety of surgical approaches can be used to excise the tumor. The choice of approach needs to be individualized with total excision providing excellent results.
