“…This task can be challenging in patients with poor anatomical landmarks, especially in those who have had previous surgery or who have disease invading or engulfing the surrounding structures. [9,11] We have experienced that hyper extension of the head increases the risk of CSF leak by unintentionally directing the dissection toward the base of the skull. To minimize this from happening we always make sure to keep the neck flexed and head extended with chin up and turning head toward slightly to the right side.…”

“…It is more beneficial when operating on revision cases and patient with obscure anatomy. [11,12] There are several different techniques for transsphenoidal pituitary surgery that have been described and among them, the sub-labial transseptal approach and transnasal transseptal approach are used most commonly. In our study, there were 103 patients who underwent transnasal transseptal approach and 5 patients with sub-labial transseptal approach.…”

Objective The aim of this study was to systematically collect data of patients undergoing transsphenoidal hypophysectomy and analyse with regard to clinical presentation, short and long term complications and demographic details. Methods This is a prospective study of transsphenoidal pituitary surgery at National Hospital Sri Lanka from May 2013 to August 2019. 108 patients who underwent transsphenoidal hypophysectomy for pituitary tumours were included. All the patients who underwent the procedure for the first time and for revision surgery were included in the study. Results Out of 108 patients, there were 87 primary cases and 21 revision cases. The average age at presentation was 45.39 years. The youngest patient was 2 years and 6 months old while the oldest was 76 years. 55 patients were male and 53 patients were female. The most common complaint at presentation was headache which affected 36 patients (33.3%). The visual disturbance was the second most common presentation, occurring in 32 individuals (29.6%). 103 patients out of 108 have been operated using trans-nasal transseptal approach and rest (5) by trans labial transseptal method. The mean postoperative hospital stay was 9.8 days (range 3-17 days). The mean follow-up period was 35.7 months (range 3-75). 6 patients had died during the follow up period and 23 patients had defaulted follow up. Postoperative CSF leak occurred in 8 patients (7.4%) and anosmia was noted in 6 patients (5.5%). Conclusion Microscopic transsphenoidal pituitary is a safe and effective treatment for pituitary tumours, and the commonest complication is CSF leak. Anosmia is one of the complications of this procedure.

“…In our opinion, the most promising approach for volumetric brain shift quantification should cope with intraoperative information, both volume and surface, and with modeling of the brain shift phenomenon [2], [35]. Existing 3D imaging devices will certainly give more reliable information regarding the volume deformation.…”

Intraoperative brain deformations decrease accuracy in image-guided neurosurgery. Approaches to quantify these deformations based on 3-D reconstruction of cortectomy surfaces have been described and have shown promising results regarding the extrapolation to the whole brain volume using additional prior knowledge or sparse volume modalities. Quantification of brain deformations from surface measurement requires the registration of surfaces at different times along the surgical procedure, with different challenges according to the patient and surgical step. In this paper, we propose a new flexible surface registration approach for any textured point cloud computed by stereoscopic or laser range approach. This method includes three terms: the first term is related to image intensities, the second to Euclidean distance, and the third to anatomical landmarks automatically extracted and continuously tracked in the 2-D video flow. Performance evaluation was performed on both phantom and clinical cases. The global method, including textured point cloud reconstruction, had accuracy within 2 mm, which is the usual rigid registration error of neuronavigation systems before deformations. Its main advantage is to consider all the available data, including the microscope video flow with higher temporal resolution than previously published methods.

Background:Surgical treatment of pituitary pathologies has evolved along the years, adding safety and decreasing morbidity related to the procedure. Advances in the field of radiology, coupled with stereotactic technology and computer modeling, have culminated in the contemporary and widespread use of image guidance systems, as we know them today. Image guidance navigation has become a frequently used technology that provides continuous three-dimensional information for the accurate performance of neurosurgical procedures. We present a discussion about the application of image guidance in pituitary surgeries.Methods:Major indications for image guidance neuronavigation application in pituitary surgery are presented and demonstrated with illustrative cases. Limitations of this technology are also presented.Results:Patients presenting a history of previous transsphenoidal surgeries, anatomical variances of the sphenoid sinus, tumors with a close relation to the internal carotid arteries, and extrasellar tumors are the most important indications for image guidance in pituitary surgeries. The high cost of the equipment, increased time of surgery due to setup time, and registration and the need of specific training for the operating room personnel could be pointed as limitations of this technology.Conclusion:Intraoperative image guidance systems provide real-time images, increasing surgical accuracy and enabling safe, minimally invasive interventions. However, the use of intraoperative navigation is not a replacement for surgical experience and a systematic knowledge of regional anatomy. It must be recognized as a tool by which the neurosurgeon can reduce the risk associated with surgical approach and treatment of pituitary pathologies.
