Microvascular decompression is a well-established technique used to relieve abnormal vascular compression of cranial nerves and associated pain. Here the authors describe three cases in which a sling technique was used in the treatment of cranial nerve pain syndromes: trigeminal neuralgia with predominant V2 distribution, hemifacial spasm, and geniculate neuralgia and right-sided ear pain. In each case, the artery was mobilized from the nerve and tethered with a sling. All three patients had reduction of symptoms within 6 weeks.

Spinal instability may arise as a consequence of decompressive lumbar surgery. An oblique lumbar interbody fusion combined with pedicle screw fixation can provide indirect decompression on neural elements, stabilization of mobile spondylolisthesis, and restoration of segmental lordosis. Minimally invasive techniques may facilitate a shorter hospitalization and faster recovery than a traditional open revision operation. The authors describe the use of an anterior interbody fusion via an oblique retroperitoneal approach and posterior pedicle screw fixation to treat a 67-year-old woman who developed L3–4 and L4–5 unstable spondylolisthesis after a lumbar laminectomy.

Anterior two-thirds corpus callosotomy is a common palliative surgical intervention most commonly employed in patients with atonic or drop seizures. Recently, stereotactic laser ablation of the corpus callosum without a craniotomy has shown promise in achieving similar outcomes with fewer side effects and shorter hospitalizations. The authors demonstrate ablation of the anterior two-thirds corpus callosum in a patient with Lennox-Gastaut syndrome and drug-resistant drop seizures. Technical nuances of laser ablation with 3 laser fibers are described. Postoperatively, the patient showed a significant reduction in seizure frequency and severity over a 9-month follow-up period.

Moyamoya is an uncommon disease that presents with stenoocclusion of the major vasculature at the base of the brain and associated collateral vessel formation. Many pediatric patients with moyamoya present with transient ischemic attacks or complete occlusions. The authors report the case of a 9-year-old girl who presented with posterior fossa hemorrhage and was treated with an emergency suboccipital craniotomy for evacuation. After emergency surgery, an angiogram was performed, and the patient was diagnosed with moyamoya disease. Six months later, the patient was treated for moyamoya using direct and indirect revascularization; after surgery there was excellent vascularization in both regions of the bypass and no further progression of moyamoya changes. This case illustrates a rare example of intracerebral hemorrhage associated with moyamoya changes in the posterior vascularization in a pediatric patient and subsequent use of direct and indirect revascularization to reduce the risk of future hemorrhage and moyamoya progression.
