Background: Cerebrospinal fluid (CSF) leak is a devastating complication after transsphenoidal surgical approach to pituitary adenoma and sellar repair has been postulated as crucial step in this approach. In this study, we describe our experience regarding sellar repair in pure endoscopic endonasal approach in 240 patients with pituitary adenoma. Methods: During April 2005 to April 2011, a tot...

  Background: Nose is used as a corridor in endoscopic endonasal transsphenoidal approach (EETSA) for pituitary adenoma. Thus, it may affect the nasal airway patency, function and sinonasal-related quality of life. The aim of this study is to objectively and subjectively evaluate these effects.   Methods: In this prospective study, 43 patients with pituitary adenoma who were c...

The endoscopic endonasal transphenoidal approach has proven to be a very versatile surgical approach for the resection of small midline skull base tumors. This is due to its minimally invasive nature, the potentially fewer neurological complications, and lower morbidity in comparison to traditional craniotomies. This surgical approach has been less commonly utilized for large midline tumors suc...

Treatment goals following skull base surgery have shifted over the last decade to improving functional outcomes and quality of life. Given the intimacy of skull base tumors to vital structures, the potential for morbidity, functional impairments, and a decline in quality of life after surgery is possible. The endoscopic endonasal approach may have potential functional outcome and quality of lif...

JNA (Juvenile nasopharyngeal angiofibroma) is a benign but highly vascular and aggressive tumor that takes its origin in the basisphenoid region close to the sphenopalatine foramen. It occurs invariably in male teenagers. Surgery is the treatment of choice. In the past, external transfacial approaches were recommended. Nowadays endonasal endoscopic approach is performed by experienced teams eve...

Pituitary apoplexy is an uncommon phenomenon typically characterized by vascular insufficiency or acute hemorrhage into a pituitary adenoma. The overall incidence of pituitary apoplexy ranges between 1 and 25% of all pituitary adenomas. With the widespread use of MRI technology, the diagnosis of asymptomatic intratumoral hemorrhage is closer to 10%. The authors report a case of a 27-year-old fe...

Background Schwannomas of the vidian canal are an extremely rare type of intracranial tumor that can have variable clinical presentations including headache, facial pain, facial muscle paralysis, decreased lacrimation, or nasal dryness. We present an atypical case of an incidentally identified asymptomatic vidian canal schwannoma. Case Description A 49-year-old woman with a history of multiple ...

To circumvent the disadvantages of endoscopic dacryocystorhinostomy such as small rhinostomy size, high failure rate and expensive equipment, we hereby introduce a modified technique of non-endoscopic mechanical endonasal dacryocystorhinostomy (NE-MEDCR). Surgery is performed under general anesthesia with local decongestion of the nasal mucosa. A 20-gauge vitrectomy light probe is introduced th...

Background: In recent years, many techniques for endoscopic closure of CSF leaks have been described and almost completely replaced the more traumatic transcranial and extracranial procedures. Aim of work: To evaluate endoscopic endonasal multilayer repair of CSF rhinorrhea of anterior and middle cranial fossae utilizing the vascularized middle turbinate rotational flap. Patients and methods: T...

OBJECTIVE Our aim in this study was to identify the endoscopic anatomy of the anterior cranio-vertebral junction to be able to perform minimal invasive endoscopic surgical procedures to this region (such as dens resection) safely with better postoperative performance of the patients. MATERIAL AND METHODS Five fresh adult cadavers were studied (n=5). We used Karl Storz 0 and 30 degree, 4mm, 18...
