An 51-year-old man had undergone surgery for Rathke's cleft cyst by transsphenoidal approach on October 2015. After the surgery, cerebrospinal fluid (CSF) rhinorrhea arose. Surgical treatment of CSF rhinorrhea was performed by the same approach. Ten days after reoperation, he suffered from severe headache, high fever, and nuchal rigidity. CSF findings indicated bacterial meningitis. CSF culture showed methicillin-resistant Staphylococcus lugdunensis. He received vancomycin intravenously for 19 days and recovered from the bacterial meningitis with no serious complication...

BACKGROUND: In Rathke cleft cysts (RCCs), inflammation by the cyst contents infrequently spreads to the surrounding structures. Calcification, which is regarded as a consequence of chronic inflammation of the cyst wall, can rarely be found in RCCs, and moreover, ossification is extremely rare. CLINICAL PRESENTATION: A 60-year-old woman presented with headaches, fatigue and weight loss due to panhypopituitarism. Magnetic Resonance imaging revealed a mass lesion in the sellar region, which was comprised of two different parts, with hypointensity anteriorly and hyperintensity posteriorly on T1-weighted image (WI), and the rim with significant hypointensity entirely on T2-WI...

INTRODUCTION: Pituitary surgery involving different techniques is often applied to the excision of benign adenomas. Operative interventions involved various approaches and techniques. Endoscopic transsphenoidal approach is the less traumatic route to the sella turcica, avoiding brain retraction, and also permitting good visualization, with lower rates of morbidity and mortality. Although mortality of pituitary surgery decreased by advances in surgical techniques morbidities such as synechiae formation, anosmia, bleeding, nasal septal perforations, drying, and incrustation due to traumatization of the nasal structures such as septum, nasal mucosa, and middle concha are the current problems in pituitary surgery...

BACKGROUND: The endoscopic transclival approach is a method for reaching the anterior side of the brainstem. In making this approach, bleeding from the basilar plexus is often observed when cutting the dura overlying the clivus; controlling such bleeding is essential. CASE DESCRIPTION: We performed a transvenous embolization of the basilar plexus before making the transclival approach. After embolization, bleeding from the basilar plexus during the operation decreased considerably...

OBJECTIVE: The transition from microscopic to a 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...

OBJECTIVE Endoscopic resection of pituitary adenomas has been reported to improve vision function in up to 80%-90% of patients with visual impairment due to these adenomas. It is unclear how these reported rates translate into improvement in visual outcomes and general health as perceived by the patients. The authors evaluated self-assessed health-related quality of life (HR-QOL) and vision-related QOL (VR-QOL) in patients before and after endoscopic resection of pituitary adenomas. METHODS The authors prospectively collected data from 50 patients who underwent endoscopic resection of pituitary adenomas...

Endoscopic endonasal approach has been successfully used for the management of pituitary tumors; however, the loss of septal mucosa especially around sphenoethmoidal recess and posterior nasal septum might be a disadvantage of this technique. The aim of this study is to describe a variation of the endonasal approach, "double nasoseptal flap" technique in endoscopic transsphenoidal pituitary surgery, and to evaluate its outcomes. The technique depends on fully harvested bigger nasoseptal flap on one side and smaller on the other...

Transsphenoidal surgery (TSS) was introduced into the Republic of Uzbeksistan in 2005, and has been developed there since. The principal center for the management of all pituitary disease is in a single site for a nation of approxiamately 30 million population. Results in the surgery of Cushing's disease (CD) are a marker of surgical technical skill in TSS. All previously published series come from the developed world where sophisticated investigations and management are available. Many of these investigations are not available in Uzbekistan...
