Disease relevance of Sphenoid Sinus

• Extrapituitary causes of acromegaly include eutopic GH cell adenoma in the sphenoid sinus or parapharyngeal region and excess GHRF secretion which may be eutopic or ectopic [1].
• We undertook this study to evaluate the potential etiopathogenesis of spontaneous CSF fistula involving the sphenoid sinus and to review the imaging findings [2].
• Both patients had midline basilar skull fractures that traversed the midclivus through the sella turcica floor, dorsum sellae, and sphenoid sinus [3].
• Aspergillosis of the sphenoid sinus: presentation as a pituitary mass and postoperative gallium-67 imaging [4].
• Hepatocellular carcinoma presenting as sphenoid sinus metastasis [5].

High impact information on Sphenoid Sinus

• Fractures of the planum sphenoidale, the floor of the sphenoid sinus, and bilateral fractures of the lesser wings are also shown [6].
• FluoroNav provided accurate, continuous information regarding the anatomic midline trajectory to the sella turcica as well as anatomic structures (e.g., sella, sphenoid sinus) in the lateral view [7].
• We evaluated each of the 11 patients for the exact site of CSF leak in the sphenoid sinus [2].
• METHODS: Coronal CT was performed in seven patients with expansile or erosive benign lesions of the sphenoid sinus, and results were compared to a control population of 72 subjects with unopacified sphenoid sinuses [8].
• RESULTS: Of 219 women, 92% with preoperative prolactin (PRL) values of < or = 100 ng/ml and 91% with intrasellar microadenomas experienced initial remission; 80 to 88% of patients with intrasellar macroadenomas or macroadenomas showing moderate suprasellar extension or focal sphenoid sinus invasion experienced remission [9].

Chemical compound and disease context of Sphenoid Sinus

• Intracranial invasive aspergillosis originating in the sphenoid sinus: a successful treatment with high-dose itraconazole in three cases [10].

Biological context of Sphenoid Sinus

• Lowest bone density was found at the lateral wall of the sphenoid sinus (3.31 +/- 0.99 mm aluminum [Al]); highest density was measured at the roof of the sphenoid sinus (12.91 +/- 1.75 mm Al) [11].

Anatomical context of Sphenoid Sinus

• We measured the distances and angles for identifying the natural ostium of the sphenoid sinus using several reference points such as the limen nasi, the sill, and the posteroinferior end of the superior turbinate [12].
• MRC showed CSF leakage in 14 patients with rhinorrhoea at the time of the examination, into the ethmoid air cells in nine, the sphenoid sinus in three and the frontal sinus in two cases [13].
• OBJECTIVE: Delineate the relationships among the optic nerve (CN II), the sphenoid sinus, and the sphenoethmoid cell [14].
• The morphological changes, proliferation, and differentiation of sphenoid sinus mucosa were examined after incubation with different LPS or LTA concentrations [15].
• Heavily T2-weighted magnetic resonance (MR) imaging (MR cisternography) in the coronal plane clearly delineated a fistulous tract through the sphenoid bone into the sphenoid sinus [16].

Associations of Sphenoid Sinus with chemical compounds

• A regimen of stress doses of hydrocortisone and antibiotics was prescribed, and the patient underwent transsphenoidal drainage of the sphenoid sinus [17].
• The prevalence of types 0 to 4 CN II position relative to the sphenoid sinus was 4.7%, 25.8%, 39.8%, 14.1%, and 15.6%, respectively [14].

Gene context of Sphenoid Sinus

• Sphenoid sinus brown tumor of secondary hyperparathyroidism: case report [18].
• A case of an ectopic prolactin-producing tumor located within the sphenoid sinus is reported [19].
• RESULTS: The natural ostium of the sphenoid sinus was located at an angle of 35.9 degrees with a distance of 56.5 mm from limen nasi and at an angle of 34.3 degrees with a distance of 62.7 mm from nasal sill [12].
• MRI evaluation indicates that a majority of patients have both acute and chronic sphenoid sinus abnormalities after TSA [20].
• There was not a statistically significant relationship between the pneumatization of the PR and ICA protrusion into the sphenoid sinus (chi2 = 0.258, p = 0.168) [21].

Analytical, diagnostic and therapeutic context of Sphenoid Sinus

• Our findings also show the efficacy of noninvasive imaging techniques, such as plain high-resolution CT and MR cisternography, in the evaluation of sphenoid sinus CSF leak [2].
• A specially designed nasal speculum is positioned to displace the posterior septum and lateralize the middle turbinates, permitting direct midline exposure of the sphenoid sinus and sella [22].
• Under local anesthesia, a needle is introduced manually through a nostril toward the sella turcica and EDH adhesive or fibrin glue is injected into the sellar cavity or sphenoid sinus, or both [23].
