 | | The sella turcica lies on the intracranial surface of the body of the sphenoid and consists of a central pituitary fossa bounded anteriorly by the tuberculum sellae and posteriorly by the dorsum sellae. | | | The aim of the study was to compare the incidence of sella turcica bridging and sella turcica dimensions in 150 Caucasian subjects who had combined surgical-orthodontic correction of their malocclusion with a randomly selected group of 150 Caucasian subjects who were treated contemporaneously by orthodontic means only. | | | The aim of this study was to compare the incidence of sella turcica bridging and sella turcica dimensions in Caucasian subjects who had undergone combined surgical-orthodontic treatment with a Caucasian group treated contemporaneously by orthodontic means only. |

| | empty sella |
| | Primary empty sella is an idiopathic form of an empty sella which occurs in the absence of prior pituitary surgery or radiation therapy or medication with DOPA agonists. | | | Secondary empty sella occurs as a result of surgical resection or irradiation of a sellar expansion. | | | These measurements are widely variable because the definition of the lateral and superior boundaries of the sella is arbitrary. |

| | Due to its anatomical location in the sella turcica, expanding lesions of the pituitary may give rise to visual disturbances, cavernous sinus syndrome(s), and headaches. | | | In some subjects this opening is much wider, and is thought to allow transmission of pulsations of the cerebrospinal fluid pressure, leading to the development of the ‘empty sella syndrome’, or cisternal herniation. | | | Thus, unless specific visualization of the bone anatomy surrounding the pituitary gland is required, a skull radiograph or sellar tomograms have little value in assessing pituitary anatomy. |

| | Dr. Fred Schudy: GROWTH INCREMENTS |
| | The entire profession of orthodontics is aware of the possible movement of sella turcica and nasion during growth. | | | Our profession has been studying the possible movement of sella and nasion for the past 65 years, and has done a wonderful job of determining the growth of the cranial base. | | | While we will continue to study and learn more about this anatomical complex, it now seems important to change the focus and begin to try to select the one most scientific analysis which we can standardize for the future. |

| | This syndrome may occur in the absence of a recognized pituitary tumor and is either primary, resulting from a congenital diaphragmatic defect which is thought to allow CSF pressure to enlarge the sella, or secondary, resulting from an injury to the diaphragm by pituitary surgery, radiation, or infarction. | | | Secondary empty sella syndrome is observed in patients with otherwise benign cerebrospinal fluid hypertension and in patients with a loss of pituitary function from apoplexy or surgical therapy. | | | Primary empty sella syndrome usually occurs in obese, multiparous, hypertensive women who experience headaches but have no underlying neurologic disorders. |

| | Transsphenoidal surgery is the usual treatment of choice for lesions confined within the sella turcica. | | | Lesions extending beyond the confines of the pituitary are most frequently the nonfunctioning chromophobe adenomas and require additional radiation therapy. | | | Growth hormone- secreting tumors can also be treated by somatostatin analogues, such as Sandostatin, with success.[2] The development of transsphenoidal hypophysectomy represents a major development in the safe surgical treatment of both hormonally-active and nonfunctioning tumors. |
