To compare efficacy and safety of microvascular decompression (MVD) and Gamma Knife surgery (GKS) treatments for trigeminal neuralgia. ⋯ Both MVD and GKS are effective surgical treatments for trigeminal neuralgia. The rate of complete pain relief in the MVD group was significantly superior to the rate of complete pain relief in the GKS group. There was no significant difference in recurrence rates between the groups; however, there were more severe complications in the MVD group than in the GKS group.

Percutaneous Endoscopic Lumbar Surgery via the Transfacet Approach for Lumbar Synovial Cyst.
There are currently no high-quality studies on the optimal therapeutic approach for juxtafacet cyst, as treatment guidelines have not been developed. Herein, a novel technique in which we used an endoscopic transfacet approach to treat a patient with symptomatic lumbar synovial cyst is presented. ⋯ Percutaneous endoscopic lumbar surgery could be a new option for the management of lumbar synovial cysts, especially when general anesthesia is not appropriate for the patient.

Case Reports Comparative Study
A Comparative Report on Intracranial Tumor-to-Tumor Metastasis and Collision Tumors.
The incidence of 2 distinct tumor types occupying the same anatomic location is rarely observed and may be accounted for by 2 separate mechanisms: tumor-to-tumor metastasis and collision tumors, where 2 adjacent tumors invade one another. These rare phenomena arise from distinct mechanisms, which may affect their preoperative recognition, surgical approach, and postoperative care. We review 2 cases, highlighting their identification and perioperative management. ⋯ Preoperative recognition of collision tumor and tumor-to-tumor metastasis is imperative for surgical planning, including selecting regions for tissue biopsy and goals of care. Meticulous evaluation of history and imaging and thorough pathologic analysis allow for effective diagnosis and optimal patient outcomes.

Transpedicular Intrabody Cage Insertion with Posterior Spine Stabilization in Kümmell Disease: Report of 2 Cases.
Kümmell disease has been treated with multiple surgical approaches, as described in the literature. However, there are few reports describing the technique of transpedicular intrabody cage insertion to enhance bony fusion and maintain the height of the vertebral body. We describe the technique of transpedicular intrabody cage insertion with posterolateral fusion in patients with Kümmell disease. ⋯ Transpedicular intrabody cage insertion is a safe and effective procedure for treating vertebral osteonecrosis to achieve bone formation at the site of vertebral osteonecrosis and to maintain body height.

Dermoid cysts are rare tumors usually seen in the midline structure of the brain but rarely arise in the petrous apex and cavernous sinus. There have been very few reports of dermoid cysts arising in the infratemporal fossa, with scarce anatomic descriptions. Here we report the case of a patient with a dermoid cyst in the left infratemporal fossa. ⋯ Dermoid cysts in the infratemporal fossa are extremely rare. However, tumor resections can be performed safely and efficaciously using anatomically detailed preoperative planning.
