To evaluate the effectiveness of a "telestration" system in which the mentor annotates the view of the surgical field, for endoscopic transsphenoidal surgery (ETS). ⋯ The use of the telestration system during ETS facilitated the communication of the mentor's intentions to the trainee surgeon and contributed to safer, more accurate surgery. The system was also thought to be useful in reducing operative time.

Meta Analysis
Outcomes of Pulsatile Tinnitus after Cerebral Venous Sinus Stenting: Systematic Review and Pooled Analysis of 616 Patients.
Pulsatile tinnitus (PT) is a debilitating condition with substantial morbidity related to quality of life. Cerebral venous sinus stenosis has recently emerged as a noninfrequent cause of PT, either in the setting of concurrent idiopathic intracranial hypertension (IIH) or due to primary venous stenosis. Venous sinus stenting (VSS) is an endovascular technique that can be used to treat venous stenosis. However, it is unclear if outcomes are different between patients with primary venogenic PT and IIH associated PT. ⋯ Venous stenting in patients with PT results in a substantial decrease and often complete resolution of symptoms. PT is more likely to recur in patients with IIH-associated PT.

The present study described a modified technique of atlantoaxial arthrodesis in patients with atlantoaxial instability (AAI) along with the postoperative clinical and radiological results. ⋯ Modified atlantoaxial arthrodesis via intraarticular autografting using the structural iliac bone combined with posterior instrumentation appears to be an efficient alternative treatment method for AAI patients with concurrent pathologies, even when the C1-2 posterior arches are unavailable for the grafting bed.

Hyponatremia is a common complication following endoscopic endonasal resection (EER) of pituitary adenomas. We report a single-center, multisurgeon study detailing baseline clinical data, outcomes, and factors associated with postoperative hyponatremia. ⋯ Hyponatremia is a common postoperative complication of EER for pituitary lesions that can cause significant morbidity, increased readmissions, and increased healthcare costs.

Screw loosening is a common complication of pedicle screw internal fixation surgery. This study aimed to investigate whether the application of a porous scaffold structure can increase the contact area between screws and bone tissue by comparing the bone ingrowth and screw-bone interface of porous scaffold core pedicle screws (PSCPSs) and hollow lateral hole pedicle screws (HLHPSs) in the lumbar spine of Bama pigs. ⋯ Compared with HLHPSs, PSCPSs possessing a porous scaffold core could promote bone ingrowth and osseointegration, resulting in an effective enhancement of the combined area of the screw-bone interface.
