“…The introduction of the operating microscope led to increasing use of microvascular decompression as a treatment for TGN (Janetta, 1976). The ability to visualize and localize aberrant blood vessels by means of advances in radiographical techniques (Meaney et al, 1994) (Fig. 1) has led to a much more widespread and effective use of microvascular decompression (Barker et al, 1996).…”

“…In a prospective study of patients with TGN and age-and sex-matched controls, high-resolution MRTA identified vascular compression in 85% of symptomatic patients compared to 8% in the controls, and in a study comparing surgical findings with MRTA, sensitivity and specificity were high [3]. In such patients, excellent results are obtained from MVD.…”

“…Diagnostic MR and MRTA scans were performed using a Siemens Magnetom 1.5-tesla MR scanner using the sequence described in which arterial blood flowing into the block gives a high signal; separate acquisitions were performed with and without gadolinium, the addition of which makes veins visible and often makes the arteries more obvious [3,4]. The Surgical Technique MVD was performed as described [2].…”

Aims: To assess whether microvascular decompression (MVD) is a safe and efficacious treatment for patients with trigeminal neuralgia (TGN) and multiple sclerosis (MS). Methods: Case records were reviewed of all patients with TGN and MS who underwent posterior fossa exploration with a view to MVD between 1993 and 2001. In all patients, magnetic resonance tomoangiography (MRTA) demonstrated vascular compression. Results: Nine patients were included in the study. Seven patients underwent MVD alone; in 2 patients a partial sensory rhizotomy of the trigeminal nerve was added to the decompression. All patients had excellent initial pain relief. Recurrence of neuralgia was noted in 5 patients after MVD and in 1 of the 2 patients after partial sensory rhizotomy. Long-term pain relief was obtained in 1 patient who underwent a redo MVD after postoperative MRTA scans demonstrated recurrent vascular compression of the root entry zone (REZ). Thus only 4 out of 9 patients maintained pain relief. In addition, 3 patients experienced transient worsening of their MS. Conclusions: Although MVD provides good initial pain relief, the recurrence rate is much higher than that obtained in ‘idiopathic’ TGN. Although all procedures for the treatment of TGN are worse than those for idiopathic TGN, it is concluded that because of the high recurrence rate together with the morbidity associated with the procedure MVD should not be offered to patients with TGN and MS.

“…55 Anterior inferior cerebellar artery, posterior inferior cerebellar atery or the vertebral artery form a loop under, over or between the VII and VIII cranial nerves and may produce symptoms, if the compression coincides with the glial Schwann cell junction. New strict criteria have been developed for the diagnosis of neurovascular conflict that in appropriate clinical setting, the vessel should be an artery, site of contact must be the root entry zone with the vessel crossing the nerve perpendicularly, and the nerve must be deviated or indented by the offending vessel or compressed or encased between two or more vessels.…”

This article reviews the role of magnetic resonance imaging (MRI) in the evaluation of lateral skull base lesions. Due to superior soft tissue resolution and multiplanar capability, MRI provides accurate information and exquisite anatomical detail. Thus, it guides the surgeon in proper preoperative planning regarding the approach of a lesion. MRI is also useful in post-treatment follow-up to assess the therapeutic response and to identify potential complications. We discuss the relevant anatomy, indications of MRI and MR pulse sequences used in the diagnosis of lesions of lateral skull base. Characteristic MRI findings of various lesions which help to arrive at a specific diagnosis as well as pitfalls of MRI which may confound the diagnosis are described. Newer MR pulse sequences enable image-guided surgery, which assist the surgeon intraoperatively, are briefly discussed. In summary, this article emphasizes the role of MRI in providing a specific answer to a clinical problem and its ability to guide the clinician for better management of patients.
