Percutaneous radiofrequency treatment of the gasserian ganglion for trigeminal neuralgia complicated by trochlear nerve palsy: a case report.

Background: Trigeminal neuralgia (TN) has the highest incidence of disorders causing facial pain. TN is provoked by benign stimuli, like shaving, leading to severe, short-lasting pain. Patients are initially treated using antiepileptic drugs; however, multiple invasive options are available when conservative treatment proves insufficient.

15. Discogenic low back pain.

An estimated 40% of chronic lumbosacral spinal pain is attributed to the discus intervertebralis. Degenerative changes following loss of hydration of the nucleus pulposus lead to circumferential or radial tears within the annulus fibrosus. Annular tears within the outer annulus stimulate the ingrowth of blood vessels and accompanying nociceptors into the outer and occasionally inner annulus.

Paravertebral blockade for minor breast surgery.

Unlabelled: Paravertebral blockade (PVB) has been advocated as a useful technique for breast surgery. We prospectively compared the efficacy of PVB via a catheter technique with the efficacy of general anesthesia (GA) for minor breast surgery. Thirty patients were randomized into two groups to receive either PVB or GA.
