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...

Treatment of frontal sinus disease represents one of the most challenging aspects of endoscopic sinus surgery. Frontal sinus mucocele drainage may be an exception to the rule because in many instances, the expansion of the mucocele widens the frontal sinus recess and renders surgical drainage technically undemanding. Recently, there has been an increased interest in in-office procedures in otol...

BACKGROUND This study examined the relationship between the superior turbinate and natural ostium of the sphenoid sinus, as seen during the endoscopic endonasal transsphenoidal approach (EETSA) for sellar lesions and described how to enter the sphenoethmoid cell safely for complete exposure of the sellar floor, including adjacent vital structures such as the prominence of the optic nerve and ca...

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 Mucoceles are slowly expanding cystic lesions with respiratory epithelium containing mucus most commonly affecting the frontal and ethmoidal sinuses. They are caused by obstruction of sinus ostium. Mucoceles exert pressure on the bony boundaries and due to the proximity to the brain and orbit extension to these areas are common. CASE PRESENTATION A case of a frontal mucocele with a...

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...

mucoceles are defi ned as chronic, cystic lesions in the paranasal sinuses. when the mucocele content becomes infected, the lesion is defi ned as mucopyocele. most mucoceles are located in the frontal and anterior ethmoid sinuses and normally they involve the frontal-ethmoid complex, expanding to the superior-medial region of the orbit, leading to ocular disorders; maxillary sinus presentation ...

OBJECTIVES We present the clinical and radiological features, treatment protocols, and medium-long-term results of our patients following surgery for paranasal sinus mucocele, along with a review of the relevant literature. MATERIALS AND METHODS A total of 18 patients (11 women and 7 men) who underwent surgery for paranasal sinus mucocele at Kocaeli University Faculty of Medicine, Department ...

Defects in the lateral wall of the sphenoid sinus are a rare cause of cerebrospinal fluid (CSF) rhinorrhea. The etiology of these defects may be congenital or acquired. A dehiscent lateral craniopharyngeal canal, or Sternberg canal, arises from a malunion of two parts of the developing sphenoid bone: the greater wing and the basisphenoid.1,2 Originally reported in 4% of healthy adults,3 its tru...

Four patients with mucocele of maxillary sinus, observed between 1995 and 2001, with two years' follow-up, are described. Aim of the present study was to establish whether endoscopic marsupialization of the maxillary sinus mucocele is adequate resolutive treatment without complete removal of the mucocele wall, using more invasive approaches. The surgical procedure used was endoscopic endonasal ...
