- If the meningioma arises from the diaphragma sellae the posterior chiasm is damaged. (wikipedia.org)
- Anteroinferiorly, the foramen rotundum and Posterior to the sella are the tow posterior clinoid processes, dorsum sellae. (jrmds.in)
- Tuberculum sellae and sphenoid planum meningiomas usually compress the optic chiasm from below. (wikipedia.org)
- Its border superiorly by the diaphragma sella, inferiorly by thin floor of cortical bone below which lies the sphenoid sinus, laterally by cavernous sinus, anteriorly by the tuberculum sellae, anterolaterally by the tow anterior clinoid processes. (jrmds.in)
- Tuberculum sellae meningiomas are a classic tumor of the anterior fossa that present in patients with gradual visu- al deterioration secondary to optic apparatus compression. (docslib.org)
- The authors reviewed their experience at the University of California, San Francisco, in cases of tuberculum sellae meningiomas treated between 1992 and 2002. (docslib.org)
- Meningiomas of the tuberculum sellae arise from the REVIEW OF SURGICAL TREATMENT limbus sphenoidale, chiasmatic sulcus, and tuberculum.14,22 They comprise approximately 3 to 10% of all intracrani- Clinical Presentation and Demographic Features al meningiomas.19,22 Correct diagnosis and management require an appreciation of the unique clinical, neuroim- Visual deterioration is the most common problem in aging, and surgery-related features that distinguish these patients harboring tuberculum sellae meningiomas.

- The sella Turcica is a midline depression in the sphenoid bone which contains the pituitary gland and distal portion of the pituitary stalk. (jrmds.in)
- Larger diameter values were present in skeletal Class III subjects, while smaller diameter sizes were apparent in Class I subjects, so the size of Sella Turcica and pituitary gland play important role to determine the skeletal developmental, classification and occlusion of jaws. (jrmds.in)
- This study proposes a deep learning approach using intraoperative endoscopic images to discriminate pituitary adenomas from non-tumorous tissue inside the sella turcica. (bvsalud.org)
- Because growth is slow and insidious in most optic nerves laterally.14 In cases involving large tumors ex- cases, evaluation and diagnosis are typically delayed, and tending toward the planum sphenoidale, sellae, and cav- significant vision loss of one or both eyes occurs. (docslib.org)
- The most of cephalometric analysis and studies of the skull depend on the sella point to make liner and angular measurements, like Downs analysis (1948) [ 3 ], where he was used the sella landmark to make Y-axis plane that extend from sella to Gonthon (S-Gn) as one of skeletal reference plane, which indicate the degree of downward, reward or forward position of chin in relation to upper face. (jrmds.in)
- The purpose of this study was to evaluation of Sella Turcica dimension(area and perimeter) in skeletal class III malocclusion (as study group) in comparative with skeletal class I normal occlusion (as control group) among adult Ukrainian peoples by using 3D Cone-beam computed tomography (CBCT).

- As such, ernous sinus, it can be difficult to differentiate tuberculum pre- and postoperative ophthalmological evaluation for sellae meningiomas from others originating from the pla- both visual acuity and visual fields is mandatory. (docslib.org)
- The independent samples T test was used to assessed the relationship between skeletal type and sella Turcica dimension, also was used to determine if skeletal type showed the significant differences. (jrmds.in)
- When comparing the area of sella Turcica for two group, there were significant differences between the study group and the control group (P=0.0116) while the sella perimeter were non-significant differences (P=0.0662). (jrmds.in)
- When sella size was compared with skeletal type, a significant difference was found in diameter size between Class I and Class III subjects. (jrmds.in)
- The results of the present study of sella area and perimeter may be used as reference standards for Ukrainian subjects in relation to sella Turcica size. (jrmds.in)
- Tu- tients typically present with a history of uni- or bilateral berculum sellae meningiomas characteristically lie in a visual decline progressing over months to years. (docslib.org)
- Tuberculum sellae and sphenoid planum meningiomas usually compress the optic chiasm from below. (wikipedia.org)
- The sella turcica features such structures as the hypohysial fossa, tuberculum sellae and dorsum sellae. (anatomy.app)
- The tuberculum sellae is a small process in front of the hypophysial fossa. (anatomy.app)
- The lateral wall of the cavernous sinus is primarily formed by the continuation of the meningeal layer of the dura, flowing medially up from the floor of the middle cranial fossa, over the cavernous sinus, to the clinoid processes before forming the diaphragma sella. (radiopaedia.org)
