The endoscopic endonasal transsphenoidal approach (EEA) to treat sellar, parasellar, and suprasellar tumours continues to gain increased significance. Due to the close proximity of the sphenoid sinus to the carotid artery and the optic canal, it is very important for surgeons to know the anatomical features and variations of the sphenoid sinus as relevant to EEA. A prospective study of the sphe...

OBJECTIVE To report 3 cases of pneumosinus dilatans of the sphenoid sinus associated with visual loss. MATERIALS AND METHODS Retrospective case series describing history of visual loss, visual examination, visual field deficits, and radiologic imaging. RESULTS Three patients developed visual loss associated with pneumosinus dilatans of the sphenoid sinus. CONCLUSIONS Pneumosinus dilatans ...

BACKGROUND Sphenoorbital meningiomas are surgically challenging because of their nature to extend to adjacent structures. Here, we describe a case of recurrent sphenoorbital meningioma extending into the sphenoid sinus, pterygopalatine fossa, and infratemporal fossa, which was resected using combined simultaneous transcranial and endoscopic endonasal approaches. CASE DESCRIPTION A 62-year-old...

OBJECT Spontaneous meningoencephaloceles of the lateral sphenoid sinus are rare lesions that are hypothesized to result from persistence of the lateral craniopharyngeal canal. Prior reports of the management of this lesion have been limited by its relative rarity. The objective of this paper is to report the theoretical etiology, surgical technique, and outcomes in patients undergoing endoscopi...

conclusions an extremely rare condition, a spontaneous intracranial pneumocephalus with skull base defect origin could be considered as a possible diagnosis in patients with sudden and severe headache. we can safely conclude that medical treatment and close follow-up is an effective mode of therapy in this patient. introduction spontaneous pneumocephalus without any pathological condition is ve...

BACKGROUND AND PURPOSE DAVFs rarely involve the sphenoid wings and middle cranial fossa. We characterize the angiographic findings, treatment, and outcome of DAVFs within the sphenoid wings. MATERIALS AND METHODS We reviewed the clinical and radiologic data of 11 patients with DAVFs within the sphenoid wing that were treated with an endovascular or with a combined endovascular and surgical ap...

There has been significant evolution over time from external headlight sinus surgery to endoscopic sinus surgery(ESS). ESS was pioneered by Messenklinger, who discovered that the sinuses had a predetermined mucociliary clearance pattern towards the natural ostium irrespective of additional openings into the sinuses. This philosophy of opening the natural ostium of the diseased sinus was then po...

Objective: This study aims to analyze the complications of endoscopic transsphenoidal surgery for pituitary neoplasms. Methods: 326 patients who underwent neuroendoscopic endonasal transsphenoidal surgery at the neurosurgery department of the First Affiliated Hospital of Chongqing Medical University from July 2012 to July 2015 were enrolled in this retrospective analysis. Results: Among the 326...
