简要总结
To investigate whether MRI is able to predict the exact anatomy and topography of the sphenoid sinus and its relationship to the sellar, parasellar und paraclinoid region and where CT yields more detailed information for the surgeon before trans-sphenoidal pituitary adenoma surgery.
详细描述
The current research project addresses the question whether MRI alone is sufficient for preoperative planning and computer-assisted surgery (CAS) during standard trans-sphenoidal pituitary surgery and if situations can be identified, where additional CT yields more information for the surgeon.
A comparison of MRI with CT of the skull base or paranasal sinuses and intraoperative Video documentation of the anatomical site will be used.
50 patients operated the University hospital of Basel [USB] (Centre A) are consecutively included into the prospective part of the study. MRI is used to assess the standardized variables, confirmed by CT. Additionally, for the 50 prospectively collected patients, neuroimaging results are correlated with intraoperative evaluation during endoscopic trans-sphenoidal surgery or post-hoc with video analysis of the performed surgery.
Between 20-50 patients operated at the University of Malaya Medical Centre [UMMC] and Specialist Centre [UMSC] (Centre B)will be included retro- and prospectively . MRI is used to assess the standardized variables and the results are correlated with intraoperative evaluation during endoscopic trans-sphenoidal surgery or post-hoc with video analysis of the performed surgery.

结局指标
主要结局
Posterior Insertion Site of the sphenoid septum at Cavernous Carotid and/or Optico-Carotid-Recess
时间窗: duration of endoscopic transsphenoidal surgery
To compare the relative performance of the MRI and the CT scan regarding posterior insertion site of the sphenoid septum at cavernous carotid and/or optico-carotid-recess. Neuroimaging results are correlated with intraoperative evaluation during endoscopic transsphenoidal surgery.
