Avoiding the Blinded Funnel: A Combined Single Piece Fronto-Temporo-Orbito-Zygomatic Craniotomy Endoscopic-Assisted Approach with Multimodal Assistance for an Epidermoid Tumor of Meckel's Cave-Case Report.

A Meckel's cave tumor poses a great challenge because of the peculiar neurovascular structure of the area and the deep location. Multiple surgical approaches have been designed for this area. In this report, we describe a case treated with a combined one step single piece fronto-temporo-orbito-zygomatic craniotomy (FTOZ) endoscopic-assisted approach for the treatment of an epidermoid tumor of Meckel's cave. A 51-year-old woman presented with a clinical history of left trigeminal neuralgia and paresthesia. CT imaging revealed a left basal temporal tumor. MR showed a tumor located in Meckel's cave near the cavernous sinus, with a good enhancement after gadolinium administration. The tumor was resected through a lateral basal subtemporal extradural approach followed by an intradural approach using intraoperative neuronavigation, endoscopic assistance, neurophysiological monitoring, and an intraoperative ultrasound probe. The lesion was completely removed. No new onset neurological damage has occurred. The symptoms improved following surgery. The aesthetic appearance of the patient was respected. The combined approach with a single piece fronto-temporo-orbito-zygomatic craniotomy has enabled us to work on a wider operating field to completely remove the lesion avoiding blind spots.

Correlation Between Cervical Spine Sagittal Alignment and Clinical Outcome After Standalone Intersomatic Titanium Cage CeSPACE for Cervical Anterior Discectomy and Fusion in Cervical Degenerative Disk Diseases.

The aim of this study was to determine the relationship between cervical spine sagittal alignment and clinical outcomes after using a standalone intersomatic titanium cage CeSPACE for anterior cervical discectomy and arthrodesis. We present our clinical experience in a group of 180 patients with a mean follow-up for at least 2 years. Patients were evaluated by clinical and radiological assessment preoperatively, immediately after surgery and at regular follow-up. There were 97 male and 83 female patients (average age: 56.6 years) who were preoperatively affected by cervical radiculomyelopathy that was due to spondylosis or cervical disk herniation and who underwent surgical treatment. All patients underwent an anterior discectomy and interbody fusion through the positioning of one or more levels of the CeSPACE device. Compared with the preoperative scores, improvement was seen in postoperative visual analog scale (VAS) scores and Neck Disability Index (NDI) values. The standalone intersomatic titanium cage CeSPACE for anterior cervical discectomy and arthrodesis improved radiculomyelopathy and increased the probability of cervical kyphotic alignment. However, cervical sagittal alignment after surgery was not significantly associated with clinical outcomes in terms of postoperative improvement in VAS scores and NDI values. Similarly, the change in cervical sagittal alignment was not related to visual analog scale scores or Neck Disability Index values.
