[Chronic sphenoid sinusitis].

Sphenoid sinusitis is often ignored by doctors, for the sphenoid sinuses are the most neglected paranasal sinuses and sphenoid sinusitis lacks specific symptoms. 58 cases of sphenoid sinusitis were reported in this article. The specific clinical symptoms remain to be deficient. At present, computerized tomography, MRI and telescope help to make accurate evaluation of sphenoid sinus diseases. The endoscopic intranasal surgery for sphenoid sinusitis enables the complicated surgical procedures simple. In our series, most cases (53) are sphenoethmoid sinusitis. The isolated sphenoid sinusitis is rare in clinical practice.

Magnetic resonance imaging of carotid artery abnormalities in patients with sphenoid sinusitis.

Sphenoid sinusitis is unusual in children, but when it occurs, it can lead to serious intracranial complications. We show the value of MRI in demonstrating intracranial abnormalities due to sphenoid sinus infection, particularly those involving the internal carotid arteries and cavernous sinuses. We reviewed our imaging experience of sphenoid sinusitis and found four patients with ICA narrowing who had undergone MR evaluation including conventional and diffusion imaging. MR angiography was also performed in three patients to determine the extent of ICA narrowing. Narrowing of ICA was found in the cavernous segment in all patients and in the supraclinoid segment in three. Cerebral infarction was found in two patients. In one patient the cavernous sinus showed hyperintensity on diffusion-weighted images and hypointensity on apparent diffusion coefficient map, suggesting reduced diffusion. Although infrequent in children, sphenoid sinus infection should be considered as a possible cause of intracranial infection, particularly in teenagers. Early recognition of cavernous sinus involvement and ICA narrowing may lead to prompt treatment and hence a more favorable outcome.

Reversible blindness secondary to acute sphenoid sinusitis.

Sphenoid sinusitis is an elusive diagnosis with significant morbidity if not diagnosed and treated promptly. We have reported an unusual case of acute sphenoiditis mimicking Gradenigo's syndrome. This resulted in virtual bilateral blindness that entirely resolved with aggressive surgical and medical treatment. It is recommended that sphenoid sinusitis be strongly considered in patients with acute headache and fever. A detailed cranial nerve examination should be performed, and CT scans of the skull base and paranasal sinuses should be obtained. Immediate surgery is strongly recommended for acute sphenoid sinusitis at the first suggestion of a complication and in those patients not promptly responding to medical therapy. It is apparent that irreversible damage to the optic nerve can occur before the development of gross intraorbital pathology. Therefore we believe that delaying surgery until the visual acuity is worse than 20/60, as advocated by some authors, may not be in the patient's best interest. Surgery should be directed at removing the purulent material, obtaining cultures, removing irreversibly diseased mucosa, and maintaining drainage of the sphenoid sinus.

[Sphenoid sinusitis].

Sphenoid sinusitis is uncommon, with an incidence of about 2.7%. Failure to diagnose and treat sphenoid sinus disease has been shown to lead to serious neurologic sequellae. Plain radiographs play a limited role in the management of sinusitis. CT scan can provide a positive diagnosis by the visualization of mucosal thickening, air-fluid level and complete opacification of the sinusal cavities. In addition, CT can provide more information about the anatomy and abnormalities of the sphenoid sinus. MRI is used in cases of suspected tumors or neurologic involvement. The most common presenting symptom is headache that arise characteristically, but rarely, from the vertex. Sphenoiditis has a high risk of severe neurologic involvement, cavernous sinus thrombosis being one of the most serious complications.

Mucous cyst of the sphenoid sinus.

Sphenoid sinus mucous cysts are rare, benign, expansile masses, which can form mucoceles if the entire sinus is filled. Due to their close proximity to numerous important anatomical structures, they can cause a variety of different symptoms. The incidental finding of a sphenoid sinus mucous cyst during cephalometric radiology for orthodontic analysis is reported.

[Mucocele of the sphenoid sinus].

Sphenoid sinus mucoceles are pseudocystic expansile slow-growing processes that arise within the sphenoid sinus. A dynamic process of bone resorption and erosion results in a pseudo-tumoral development. Clinical features and potential risks are related to mass effect with compression of the optic nerves and intracranial extension of the process. CT and MRI allow diagnosis and distinguish mucoceles from skull base tumors or inflammatory diseases. Endonasal endoscopic approach is adapted to the treatment of sphenoid mucoceles and allows marsupialization of the mucoceles.

[Diagnosis by cranial computer tomography of sphenoidal sinusitis].

Sphenoidal sinusitis is an uncommon pathology potentially dangerous condition, that we can find in young population. Clinically it is very difficult to diagnose because of its nonspecific symptoms, but cranial computer tomography confirms the diagnosis. The most cases were treated with antibiotics and recovered completely. We present a young man with isolated sphenoidal sinusitis who was managed in our medical centre, and a review of the literature.

Papillary carcinoma of the sphenoid sinus associated with sphenoid sinus abscess presenting as cavernous sinus syndrome. A case report.

Primary carcinoma of the sphenoid sinus is a rare tumor that may present with dramatic neuro-ophthalmological-symptoms and signs of which spheno-cavernous syndrome is the best known clinical entity. The most frequently encountered histological types of the sphenoid carcinomas are squamous cell carcinoma and papillary carcinoma, in decreasing order of frequency. In this article, a papillary carcinoma of the sphenoid sinus associated with sphenoid sinus abscess is presented. We are not aware of previously reported papillary carcinoma of the sphenoid sinus associated with sphenoid sinus abscess presenting as a cavernous sinus syndrome.

Intractable headache: aseptic meningitis and sphenoidal sinusitis.

Sphenoid sinusitis, an uncommon cause of headache, is associated with significant morbidity. A 30-year-old man presented with a progressive intractable headache and aseptic meningitis. Failure to recognize sphenoid disease on brain CT delayed diagnosis; treatment with i.v. antibiotics resolved the disorder.

Invasive fungal sinusitis of isolated sphenoid sinus in immunocompetent subjects.

Invasive fungal sinusitis of the paranasal sinuses in a healthy immunocompetent person is uncommon. Isolated involvement of any paranasal sinus, particularly sphenoid sinus is rare. In this study, five immunocompetent patients who had no nasal complaints but obscure symptoms of headache and orbital symptoms such as diplopia, retro-orbital pain and loss of vision were diagnosed to be having fulminant fungal sinusitis of the sphenoid sinus. Three patients had aspergillosis and two patients had mucormycosis. These patients initially presented to neurologists and ophthalmologists because they had no ENT complaints. The diagnosis was made on endoscopy, radiology and histopathology. They were treated aggressively according to the standard protocols. The purpose of this paper is to bring to light the changing clinical spectrum of invasive fungal sinusitis. It can occur in immunocompetent patients and in the form of isolated sphenoid sinus involvement.

Isolated sphenoid sinusitis.

Isolated sphenoid sinusitis is a relatively rare clinical entity and can cause severe complications. Diagnostic nasal endoscopy using Hopkins telescopes and coronal and axial paranasal-sinus CT made the diagnosis of the sphenoid sinus disease easier. Eight out of 221 patients with paranasal sinus infection refractory to medical treatment--and treated surgically at the 2nd ENT Clinic of Ankara Numune Hospital between 1990-1995--had isolated sphenoid sinus infection. The most common symptom was headache felt in the retro-orbital region. Surgical procedure was intranasal endoscopic approach to the sphenoid sinus. The symptoms of the patients with isolated sphenoid sinusitis were completely resolved after surgery. As the literature is reviewed, it is concluded that endoscopic approach to the sphenoid sinus disease is the most appropriate method of surgery in order to reduce intra-operative morbidity and mortality.

Sphenoid sinus mucocele.

Sphenoid sinus mucocele is a rare entity that can occur alone or as a result of ethmoid sinusitis and polyposis. A myriad of presentations is possible due to the presence of important contiguous neurologic and vascular structures. Past surgical approaches to the sphenoid sinus have problems associated with them. The endoscopic sinus technique offers outstanding visualization and a safe, straight-forward approach to the sphenoid sinus. Four patients with documented mucocele of the sphenoid sinus were treated successfully with endoscopic sinus surgery. The technique involves partial removal of the inferior middle turbinate and direct entrance into the sphenoid sinus through the anterior sinus wall. Other sinus abnormalities can be treated simultaneously as required. Sphenoid sinus mucocele is discussed from the standpoint of cause, clinical presentation, and treatment options.

Unilateral abducens nerve palsy: a presenting sign of sphenoid sinus mucocoeles.

Sphenoid sinus mucocoeles can stimulate a variety of pathological conditions and patients can present to a range of specialists. Because of the relative rarity of sphenoid sinus mucocoeles, diagnosis is often delayed and these lesions can progressively expand and cause direct mechanical compression on adjacent structures. We present three cases which presented with an abducens nerve palsy. Early surgical intervention is advocated and these patients' symptoms resolved following surgery. Although several conditions can present with an abducens nerve palsy, it is important to consider a sphenoid sinus mucocoele in the differential diagnosis.

Transnasal bamboo foreign body lodged in the sphenoid sinus.

Transnasal sphenoid sinus foreign body is a rare condition. We report a very rare case of transnasal bamboo foreign body lodged in the sphenoid sinus without damages to the orbital wall or skull base. A 69-year-old man fell down onto a bamboo stick, which snapped after penetrating his face through the right nostril. CT demonstrated that the bamboo stick stuck into the middle meatus, penetrated the ethmoid sinus just medial to the lamina papyracea and reached to the sphenoid sinus. No abnormal findings were detected in the orbit or skull base. The foreign body was removed from the nasal cavity without any complication. The endoscope was useful for evaluating possible injuries in the orbit and skull base and confirming the absence of residual foreign bodies.

Septic complications to sphenoidal sinus infection.

Sphenoid sinusitis is an uncommon infection, but an early diagnosis and appropriate treatment is important because of its serious complications. We report 4 patients (28, 28, 37 and 28 years old) admitted to a department of infectious diseases with meningitis, sepsis and orbital cellulitis as complications of acute sphenoidal cavity infection. The cases illustrate the value of computed tomography (CT) scan of the sphenoid sinus in the evaluation of patients with clinical features suspicious of sphenoid sinusitis.

Vascular malformation of the sphenoid sinus.

Isolated sphenoid sinus lesions are usually inflammatory lesions or mucoceles. We report an unusual case of a thrombosed arteriovenous malformation presenting as a unilateral primary vascular malformation of the sphenoid sinus. To the best of our knowledge, no one has ever reported such an entity in the medical literature. Differential diagnosis of sphenoid sinus lesions and possible etiologies for this case will be detailed.
