Empty sella is a radiological-anatomical entity characterised by a sella turcica filled partially or completely with cerebrospinal fluid, leading to varying degrees of pituitary flattening. Literature reports a 5% 20% incidence of empty sella in unselected autopsies leading many to argue that it is an extreme normal variant. Endocrine dysfunction varies from 8% 25% with primary empty sella and ...

In earlier studies, a sella turcica bridge was stated to occur in 1.75 to 6 per cent of the population. The occurrence of a sella turcica bridge has not previously been studied in a group of patients with craniofacial deviations treated by surgery. Profile radiographs from 177 individuals who had undergone combined orthodontic and surgical treatment at the Copenhagen School of Dentistry were st...

OBJECT The sella turcica usually appears partially empty in MR images obtained from patients with chronic elevation of intracranial pressure. The authors measured the size of the sella turcica to determine if enlargement of the pituitary fossa explains the partially empty sella associated with pseudotumor cerebri. METHODS The medical records from 2005 to 2011 of a single neuro-ophthalmologist...

Empty sel la refers to the radiological appearance of an enlarged or deformed sella turcica that is partially or completely filled with cerebrospinal fluid. In the earlier days, the radiographic appearance of an enlarged sella turcica was frequently equated with the presence of an intra or perisellar neoplasm. It was found, however, in some of these patients on pneumoencephalography, that the e...

OBJECTIVE The purpose of this study was to investigate the effects of a newly developed rapid maxillary expansion screw-the memory screw-over 6 months. METHODS Five subjects, aged between 11.7 and 13.75 years, were enrolled in this study. All subjects underwent placement of a maxillary expansion appliance containing superelastic nickel-titanium open-coil springs in its screw bed. The parents ...

BACKGROUND In orthodontic science, diagnosis of facial skeletal type (class I, II, and III) is essential to make the correct treatment plan that is usually expensive and complicated. Sometimes results from analysis of lateral cephalometry radiographies are not enough to discriminate facial skeletal types. In this situation, knowledge about the relationship between the shape and size of the sell...

The aim of this study was to measure line segments and areas of sella turcica on lateral cephalograms with respect to the clinical diagnosis of facial phenotype of patients with neurofibromatosis type 1 (NF1). Special attention was given to correlate the measured values with certain tumour types that are typical for this disease. Material and methods: Lateral cephalograms of 194 individuals wer...

The normal functions of the pituitary gland may be suppressed when the gland is compressed onto the sella floor by arachnoid tissue extending through an impaired sella diaphragm. Interestingly, pituitary hormone hypo- and hypersecretion, including acromegaly, have been observed in patients with an 'empty sella'(1-4). This 'empty sella syndrome' has been classified into a primary form, in which ...

Introduction. Empty sella is caused by the herniation of the subarachnoid space within the sella, which results in compression of pituitary gland. The image of empty sella may be an incidental finding on MRI in asymptomatic patients, but it can be also associated with severe neurological, ophthalmological and endocrine disorders. Aim. The aim of the study was to analyze clinical and hormonal da...

BACKGROUND The purpose of this study was to determine and compare the shapes, sizes, and bridging of the sella turcica in patients with different skeletal patterns and genders. METHODS It was a cross-sectional comparative study. The samples were divided into three groups according to the skeletal pattern viz. Class I, Class II and Class III, and each group consisted of 40 samples (20 males an...
