Atlantoaxial fixation as treatment of trigeminal neuralgia in a patient having basilar invagination.
Trigeminal neuralgia can rarely be identified in association with basilar invagination. The presented case report observes that the treatment of basilar invagination by atlantoaxial fixation can result in lasting relief from trigeminal neuralgia. ⋯ The pathogenesis of trigeminal neuralgia and its relationship with atlantoaxial instability is speculated.

The globus pallidus internus (GPi) and subthalamic nucleus (STN) are therapeutic targets for deep brain stimulation (DBS) in the treatment of isolated dystonia. We conducted a meta-regression analysis on long-term studies of bilateral DBS in the GPi and STN to compare the relative effects of the 2 approaches. ⋯ A shorter disease duration correlated positively with better DBS outcomes. The STN appeared to be an optimized stimulation target for the treatment of isolated dystonia, although randomized controlled trials are needed to compare the treatment efficacy of GPi DBS and STN DBS.

Pituitary adenomas (PA) are usually benign neoplasms. Chiari I malformation (CIM) is an uncommon finding. Isolated cases associating functional PA and CIM have been reported. The concomitant presence of a nonfunctional PA and a CIM has not yet been described in the literature. ⋯ This is the first reported case of a concomitant CIM and a nonfunctional PA. We discuss our successful management and conduct a systematic review of the literature to provide the most up-to-date guidance on managing these singular cases with concomitant pathologic conditions.

In open brain surgery, fixation of the bone flap is the final procedure. The bone flaps then fuse naturally. The objective of this study was to investigate the chronological process of bone fusion after craniotomy and autologous cranioplasty. ⋯ Bone flap fusion rates after craniotomy and cranioplasty were significantly different before 12 months, but not significantly different thereafter. Bone resorption occurred more frequently in the cranioplasty group over time.

This paper reports the case of a giant saddle area lymphoid epithelial carcinoma as reference for clinical diagnosis and treatment. The clinical data of 1 patient who suffered from giant saddle area lymphoid epithelial carcinoma that invaded the bilateral cavernous sinus and surrounding internal carotid artery, slope, nasopharynx, oropharynx, sphenoid sinus, and ethmoid sinus were retrospectively analyzed. The treatment process and relevant literature were summarized. ⋯ Giant saddle area lymphoid epithelial carcinoma is rare. Surgical removal should be selected as the initial treatment, and postoperative radiotherapy is indispensable for lymphoid epithelial carcinoma of the skull base and sinus.
