Pituitary adenomas are benign tumors of the anterior pituitary gland, with incidence rates between 4 and 78 per 100,000...
Surgical Navigation Systems
Evolution of Surgical Navigation Systems
Surgical navigation systems are popular tools during sinus and skull base surgery, which allow the surgeon to upload CT scans of individual patients into a computer. The scans are then synchronized with the surgical instruments, so that the exact location of the surgical instrument can be visualized in relation to its whereabouts on the patients 3D CT scan rendering. This allows the surgeon to localize key structures, and validate spatial anatomy that is seen endoscopically. Image guidance systems are a valuable tool in preventing injury to these key structures.
The StealthStation surgical navigation system allows you to see your instrument tip on the screen, which allows a safer and more thorough resection, and can decrease the chances of violating important anatomic structures. Knowledge of precise surgical location is important during skull base surgery, as vital structures such as the brain, carotid arteries, optic nerves, and orbit are all in close proximity.
The CT image uploaded must be fine cut(1mm slices). Image guidance is used to confirm the correct location when resection a portion of the posterior nasal septum, and when drilling away the skull base directly inferior to the pituitary adenoma. Once the adenoma is located, the StealthStation guidance is used to demarcate the extent of skull base that must be resected in order to completely visualize and remove the tumor.
