Background  Injury to the cavernous portion of the internal carotid artery (ICA) during endoscopic skull base surgery is a well-recognized rare complication that can be associated with high rates of morbidity and mortality. Many techniques have been suggested to manage ICA injury with varying degrees of success. Objectives  We provide a detailed technical description of an operative technique f...

OBJECTIVES/HYPOTHESIS To conceive and critically evaluate an adaptation of the split calvarial osteopericranial flap for reconstruction following endoscopic endonasal resection of the anterior skull base. STUDY DESIGN Cadaveric anatomic study. METHODS Five cadavers were embalmed with methanol, and vasculature was injected with latex. Endoscopic endonasal resection of the anterior skull base...

OBJECTIVE To develop a new staging system for juvenile nasopharyngeal angiofibroma that reflects changes in surgical approaches (endonasal), route of intracranial extension, and the extent of vascular supply from the internal carotid artery. DESIGN Retrospective review of case series. SETTING Academic medical center. PATIENTS Patients undergoing endoscopic endonasal surgery for juvenile n...

OBJECTIVES/HYPOTHESIS To validate the endonasal surgical approach to frontal sinus in inflammatory sinus disease, trauma, and selective tumor surgery, and to define the role of external approaches to the frontal sinus. Endonasal frontal sinusotomy can range from endoscopic removal of obstructing frontal recess cells or uncinate process to the more complex unilateral or bilateral removal of the ...

Introduction: Non Endoscopic endo-nasal dacryocystorhinostomy retains the benefit of an Endo-nasal approach and can be done without using expensive video endoscope or laser system.
 Case presentation: A 22 years old female presented with epiphora medial canthal mass in her left eye, accompanied by discharge recurrent conjunctival congestion since childhood. Physical examination revealed lo...

OBJECTIVE The learning curve for endonasal endoscopic and neuroendoscopic port surgery is long and often associated with an increase in complication rates as surgeons gain experience. We present an animal model for laboratory training aiming to encourage the young generation of neurosurgeons to pursue proficiency in endoscopic neurosurgical techniques. METHODS 20 Wistar rats were used as mode...

OBJECT The extended transsphenoidal approach is a less invasive method for removing purely suprasellar lesions compared with traditional transcranial approaches. Most advocates have used a sublabial incision and a microscope and have reported a significant risk of cerebrospinal fluid (CSF) leakage. The authors report on a series of purely endoscopic endonasal surgeries for resection of suprasel...

OBJECTIVE Suprasellar meningiomas have been resected via various open cranial approaches. During the past 2 decades, the endoscopic endonasal approach has been shown to be an option in selected patients. We wished to examine the learning curve for parameters such as extent of resection, visual outcome, and complications. METHODS We retrospectively reviewed a consecutive series of patients in ...

Over the last decade, the Endoscopic Endonasal Approach (EEA) has revolutionized skull base neurosurgery. The endonasal approach has anatomical and technical advantages over traditional skull base approaches for the treatment of selected lesions. EEA is not only minimally invasive but also maximally effective for the treatment of a wide variety of skull base lesions. Meticulous knowledge of the...

BACKGROUND Odontogenic cysts and tumors of the maxilla may be amendable to management by endonasal endoscopic techniques, which may reduce the morbidity associated with open procedures and avoid difficult reconstruction. OBJECTIVE To perform a systematic review that evaluates the feasibility and outcomes of endoscopic techniques in the management of different odontogenic cysts. A case series ...
