For the treatment of pituitary tumors, microscopic transsphenoidal surgery has been considered the "gold standard" since the late 1960s. Over the last two decades, however, a worldwide shift towards endoscopic endonasal surgery is in progress for many reasons. These include a wide panoramic view, improved illumination, an ability to look around anatomical corners using angled tip and, in addition, application to the extended approaches for parasellar tumors. Both endoscopic and microscopic approaches appear equally effective for nonfunctioning adenomas without significant suprasellar or lateral extensions, whereas the endoscopic approach may improve outcomes associated with the extent of resection and postoperative complications for larger tumors...

Microscopic transnasal transsphenoidal surgery (MTTS) has been a time-confirmed effective treatment for pituitary adenomas; however, the data supporting its use in pediatric patients is limited. In this study, the authors summarize the authors' 5-year experience of pituitary adenomectomy via MTTS in a pediatric population. The authors retrospectively reviewed the medical records of 35 patients aged ≤18 years who underwent microscopic transnasal transsphenoidal approach for pituitary adenomas between January 2011 and December 2015...

BACKGROUND: Cognitive impairment following transsphenoidal surgery (TSS) among patients with pituitary tumors has been intermittently reported and is not well established. We performed a systematic review to summarize the impact of TSS on cognitive function. METHODS: We conducted a systematic search of the literature using the PubMed, Cochrane, and Embase databases through October 2014. Studies were selected if they reported cognitive status after surgery and included at least 10 adult patients with pituitary tumors undergoing either endoscopic or microscopic TSS...

OBJECTIVE: Prolactinomas are the most common functional hormone-producing pituitary lesions, accounting for 30-40% of all pituitary tumors, while in autopsy series their incidence reaches 50%. However, patients with prolactinoma had a higher recurrence percentage and rate than patients with acromegaly or Cushing's disease. Furthermore, prolactinomas have the highest rate of recurrence post-surgery as compared with other pituitary adenomas. At present, this behavior of prolactinoma is largely unexplained, but may be related to definition of cure, or to more frequent microscopic tumor infiltration into normal pituitary tissue, which is not removed at surgery...

X-rays and ventriculograms were the first imaging modalities used to localize intracranial lesions including brain tumors as far back as the 1880s. Subsequent advances in preoperative radiological localization included computed tomography (CT; 1971) and MRI (1977). Since then, other imaging modalities have been developed for clinical application although none as pivotal as CT and MRI. Intraoperative technological advances include the microscope, which has allowed precise surgery under magnification and improved lighting, and the endoscope, which has improved the treatment of hydrocephalus and allowed biopsy and complete resection of intraventricular, pituitary and pineal region tumors through a minimally invasive approach...

Till date there are no randomized trials to suggest the superiority of intra-operative magnetic resonance imaging (IOMRI) guided trans-sphenoidal pituitary resection over two dimensional fluoroscopic (2D-F) guided resections. We conducted this trial to establish the superiority of IOMRI in pituitary surgery. Primary objective was to compare extent of tumor resection between the two study arms. It was a prospective, randomized, outcome assessor and statistician blinded, two arm (A: IOMRI, n=25 and B: 2D-F, n=25), parallel group clinical trial...

OBJECTIVE Regrowth of the lesion after surgical removal of pituitary adenomas is uncommon unless subtotal resection was originally achieved in the first surgery. Treatment for recurrent tumor can involve surgery or radiotherapy. Locations of residual tumor may vary based on the original approach. The authors evaluated the specific sites of residual or recurrent tumor after different transsphenoidal approaches and describe the surgical outcome of endoscopic endonasal transsphenoidal reoperation. METHODS The authors analyzed a prospectively collected database of a consecutive series of patients who had undergone endoscopic endonasal surgeries for residual or recurrent pituitary adenomas after an original transsphenoidal microscopic or endoscopic surgery...

OBJECTIVE: The transition from microscopic to fully endoscopic transsphenoidal surgery requires a surgeon to assess how the change in technique will affect the extent of tumor resection (EOR), outcomes, and complications. We compared a single surgeon's experience transitioning from one technique to the other and examined the operative outcomes and EOR between microscopic versus endoscopic transsphenoidal surgery. METHODS: Retrospective data analysis of adult patients who were treated surgically for a pituitary adenoma between August 2005 and May 2015 by a single neurosurgeon, who was originally trained and practiced in the microscopic transsphenoidal approach...

AIM: Major complications of microscopic transnasal hypophyseal surgery (MTHS), such as cerebrospinal fluid rhinorrhea, carotid injury, and optic nerve injury, are very rare. However, late rhinological complications can be ignored because they are a minor cause of morbidity compared with major complications. In this study, we extensively examined postoperative rhinological complications in patients who underwent MTHS for pituitary adenoma. MATERIAL AND METHODS: Thirty-one patients diagnosed with pituitary adenoma, who underwent MTHS and whose preoperative nasal examinations were recorded between January 2007 and January 2014, were included in the study...
