We report on a 28-year-old man with severe headache. Imaging studies included CT and MR. A large sphenoid mucocoele was demonstrated as well as findings compatible with fibrous dysplasia of the facial bones. Both disorders had been previously unknown. Imaging findings suggested that the sphenoid mucocoele was related to an obstruction caused by the expansile bone of fibrous dysplasia. These fin...

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 ...

Agenesis of paranasal sinuses is an uncommon finding mainly seen in the frontal and maxillary sinuses. Agenesis of sphenoid sinuses is an extremely rare condition. In this article, we present an 18-year-old female patient suffering from headache and nasal obstruction without any skeletal or cranial anomalies. Axial, coronal and sagittal computed tomography revealed absent sphenoid sinuses. Surg...

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...

The aim of this study was to analyze the bacterial flora in the nasal cavity and sphenoid sinus and evaluate the sensitivity of these bacteria to antibiotics that can be used to prevent postoperative meningitis. Bacteria of the preoperative nasal cavity and intraoperative sphenoid sinus mucosa were cultured and analyzed in 40 patients (20 men and 20 women; mean age, 52.2 years) who underwent en...

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...

STATEMENT OF THE PROBLEM The sphenoid sinus is a common target of paranasal surgery. Functional endoscopic sinus surgery is likely to endanger the anatomic variations of vital structures adjacent to the sphenoid sinus. PURPOSE The aim of this study was to determine the variations of sphenoid sinus and the related structures by using cone-beam computed tomography (CBCT). MATERIALS AND METHOD...

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...
