Traditional mechanical tests, such as a three-point bending, compression, and torsion, are common methods to measure macro mechanical properties, however, such tests do not provide spatial stress distribution in bones. Since signals released from mechanosensitive osteocytes control neighboring bone-forming and bone-resorbing activities, region-specific mechanical stress is considered as a key contributor to local bone remodeling and may have the potential to be scanned and analyzed with accurate and useful methods.

BACKGROUND: Trigeminal Neuralgia (TN) is a well-recognized facial pain syndrome. Discrete forms with disparate pain symptoms include TN1 and TN2, however, atypical facial pain includes neuralgiform pain along a spectrum. The majority of TN is diagnosed in the adult population. Case reports and series in children present TN as a similar diagnosis which can be similarly treated as in adults. This manuscript reviews pertinent literature and presents two pediatric TN cases successfully treated with microvascular decompression (MVD). CASE DESCRIPTION: Two pediatric patients (ages 12 and 15) were identified with TN that was refractory to previous medical therapy. The patients were both deemed appropriate surgical candidates and were treated with MVD to manage their TN. TN compression was arterial in both cases and involved portions of the anterior inferior cerebellar artery. Patient 1 was found to be pain-free 6 months following the procedure. Patient 2 was pain-free immediately following the procedure and has since been weaned off preoperative symptomatic management. The most recent follow-up is 12 and 8 months, respectively, with continued pain freedom. CONCLUSIONS: There are few reports on the effectiveness of MVD in the pediatric population for the management of TN. Supporting literature, as well as the cases presented, demonstrate that MVD is an effective treatment for pediatric patients in managing their TN. Furthermore, there appears to be minimal side effects, with excellent pain relief with MVD in this patient population
