Length Of Sella Turcica Research Articles

Examination of 3D sella turcica models in three species of ruminants.

Sella turcica is an important anatomical structure that contains the pituitary gland. Changes observed on the sella turcica facilitate the identification of diseases such as Down syndrome, Seckel syndrome and tuberculum sellae meningioma in humans. Therefore, studies in this region are critical for a better understanding of sella turcica. The crania of six adult male tuj sheep, five adult male hair goats and five adult male gazelles were used in the study. Cross-sectional images of the cranium were captured using computed tomography. Cross-sectional images were used to model the sella turcica region in 3D, and the region was analysed morphologically and morphometrically. It was observed in the study that fossa hypophysialis, dorsum sella and processus clinoideus caudalis were clearly observed on the sella turcica. The processus clinoideus caudalis in some animals was not split into two. In morphometric analysis, the sella turcica length and sella turcica height (rostral border) parameters were statistically significant between the groups (p < 0.05). Consequently, this study morphological and morphometric examinations were carried out on the sella turcica of different ruminant species, and the differences between the groups were discussed. This study is expected to contribute to the very limited number of related studies, taxonomy and clinical studies in this field.

Evaluation of Sella Turcica Morphology and Morphometry Based on Gender and Age in Our Population Using Computed Tomography.

In this study, it was aimed to determine the reference values for the healthy Turkish population by evaluating the age-related changes in the morphology and morphometry of Sella Turcica (ST) and the relationship with the body mass index. In addition, it has been investigated whether the morphology and morphometry of this structure vary in diabetes mellitus (DM) patients. The study group was consisted of a total of 524 individuals (266 females and 258 males) (426 healthy and 48 with DM) between the ages of 1 and 80, who applied to the Department of Radiology between January 2018 and February 2021. Axial brain computed tomography scans which have no pathology in ST were retrospectively examined. The ST length (STL), height (STH), diameter (STD), processus clinoideus anterior right-left (PCAR_L), processus clinoideus posterior right-left (PCPR_L) did not differ significantly in healthy individuals and individuals with DM (P>0.05). When the ST morphology according to the ST shape classification performed by Meyer Marcotti and colleagues and Axellson and colleagues was evaluated, it was observed that there was no statistically significant difference between the 2 groups (P>0.05). There was a significant difference in STL, STD values (P<0.05), however, there was no difference in STH, PCAR_L, PCPR_L values between genders (P>0.05). While the distance between STL, STD, PCAR_L showed a significant difference between the decades in all groups, there was no significant difference in the STH, PCPR_L in both classifications (P>0.05). When the relationship between the parameters and body mass index was evaluated, STL, STD, PCAR_L showed a significant difference between the groups (P<0.05). Detailed knowledge of the ST anatomy will be helpful in terms of early diagnosis of diseases that may be related and guiding surgical interventions in this region.

Cone Beam Computed Tomographic Evaluation of Shape, Linear Dimensions and Volume of Sella Turcica: A Retrospective Observational Study

Background: Sella turcica is an important saddle shaped structure that houses the pituitary gland. Any deviation in the development of the pituitary gland may affect the size and shape of the sella turcica as well. So, the morphology of the sella turcica gains special importance in certain clinical conditions. The aim of this study was to assess the shape, linear dimensions and volume of sella turcica in healthy adults using cone beam computed tomography (CBCT). Material and Methods: This retrospective study involved CBCT images of 108 healthy adults. The sagittal, axial, and coronal slices of CBCT images were used to evaluate the shape, volume and linear dimensions. Results: The overall linear dimensions of sella turcica were length 8.59 ±1.49 mm, depth 7.27 ±1.16 mm, diameter 10.24 ±1.75 mm and volume 1499.69 ± 395.5 mm3 respectively. The length of sella turcica was higher in males than females which was statistically signifcant (p = 0.015) while the depth, diameter and volume reported non-signifcant results. The most frequent shape of sella turcica was normal and the least frequent was sella turcica bridging. The Pearson correlation co-efcient was statistically significant for the length vs diameter and volume along with diameter vs volume in both genders (p &lt; 0.01). The depth was statistically correlated with length, diameter and volume in males (p &lt;0.01). Conclusion: The sella turcica shape and dimensions can be used in forensic and medicolegal purposes. So, a thorough of knowledge about this important structure is necessary.

Assessment of the Relationship between Sella Turcica Morphology and Delayed Dental Age

The purpose of this study was to evaluate the relationship between sella turcica morphology and delayed dental age. In total, 389 participants under 16 years old were selected. Dental age was evaluated by the Demirjian method and age discrepancy (AD), the value subtracted from dental age to chronological age, was calculated. The participants were divided into 8 groups based on the sella turcica type. Bridging ratio (BR) was defined as interclinoid distance divided by sella turcica length to determine the degree of sella turcica bridging (STB) and the participants were classified into 4 groups by BR. The data were statistically analyzed using the Kruskal Wallis test and the Mann Whitney test. Some groups with sella turcica abnormality showed lower AD than that of the normal group and the AD differences varied from 4 months to 1.3 year. As the STB severity increased, AD decreased. AD differences varied from 7 months to 1.19 year. No distinct differences were observed in sella turcica type and STB groups according to sex. The results indicate that sella turcica morphology is associated with delayed dental age. Sella turcica can be used as a supplementary indicator to predict dental development.

Evaluation of Dimension and Bridging of Sella Turcica and Presence of Ponticulus Posticus in Individuals With and Without Cleft: A Comparative Study.

Sella turcica abnormalities such as sella turcica bridging (STB) have been observed frequently among patients with craniofacial anomalies. Ponticulus posticus (PP) is an important structure and its presence causes complications during surgeries. Due to the importance of these structures, this study aimed to evaluate the prevalence of STB, PP, and dimensions of the sella turcica in individuals with and without cleft. A cross-sectional study. Orthodontic and Radiology Departments in a public dental school, Tehran, Iran. Eighty-three lateral cephalograms of individuals with cleft and ninety-two cephalograms of class I individuals without cleft. Length, depth, and maximum anterior-posterior diameter (APD) of sella turcica, presence of STB (classified as types 1, 2, and 3), and PP. In the group with cleft, 19.3% of individuals had type I, 65.1%, type II, and 15.7%, type III STB. In the group without cleft, 15.2% had type I, 73.9%, type II, and 10.9%, type III STB. In the group with cleft, 65.1% of individuals had no PP, 24.1%, incomplete, and 10.8%, complete PP while in the group without cleft, 56.5% had no PP, 29 31.5%, incomplete, and 12%, complete PP. The sella turcica dimensions, STB, and PP prevalence were not significantly different between individuals with and without cleft. The sella turcica length and prevalence of STB and PP were not affected by age, sex, and cleft type. However, the depth and the APD were affected by age.

Morphometric assessment of the sella turcica in different morphologic types of Class II malocclusion: a retrospective study

Objectives: Sella turcica is a substantial anatomic reference structure used to assess craniofacial growth and treatment changes in orthodontics. The aim of this retrospective study was to analyze the size and morphology of sella turcica in different subdivisions of Class II malocclusion and to compare it Class I craniofacial development. Materials and Methods: The study was conducted with 150 patient’s pre-treatment lateral cephalometric radiographs. Good-quality lateral cephalometric radiographs with a prominent appearance of sella turcica were grouped into Class II division 1, Class II division 2 and Class I (control group). On lateral cephalograms, the length, diameter and depth of the sella turcica were gauged and morphological types of the sella turcica was detected. For statistical analysis, one-way ANOVA, Kruskal Wallis analysis with Dunn-Bonferroni test and Chi-square test were used (p <0.05). Results: A significant difference was found in the length of the sella turcica in the Class II div 2 group (p <0.05) compared to the other groups. The differences in depth and diameter of the sella turcica among three groups were non-significant (p > 0.05). The appearance of the sella turcica was normal shaped in most of the subjects (60.6%). Conclusion: No significant difference was found among skeletal Class II division 1, Class II division 2 and Class I groups in terms of diameter and depth of the sella turcica. A smaller length of sella turcica was found in patients with Class II division 2 anomaly.

Size and shape of sella turcica among Down syndrome individuals in a Nigerian population

Background/Aims: This study was conducted to determine the size and shape of sella turcica (ST) among Down syndrome (DS). Materials and Methods: The size of the ST was determined among 29 DS (mean age 13.76 ± 2.41 years), while the shape of the ST was among 25 DS individuals (mean of 13.84 ± 2.41 years) who met the inclusion criteria. Statistical significance of linear measurement in relation to gender was evaluated using an independent t-test, while Chi-square test was used to analyze the occurrence and significance of the shape. A statistically significant level was set at P &lt; 0.05. Results: ST length (STL), depth (STD), and anterior–posterior diameter (STAPD) were 9.00 ± 3.23 mm, 7.61 ± 1.51 mm, and 10.45 ± 2.79 mm, respectively. Female DS had a larger value for STD and STAPD than males (P &gt; 0.05). The pyramidal shape of the dorsum sella accounted for the largest deviation (28.3%) in shape. A change in shape of the ST tend to affect the depth (F = 1.669, P = 0.204) and diameter (F = 1.425, P = 0.263) than its effects the length. Conclusion: The depth and diameter of ST were observed to be larger than normal individuals within the same age range documented in the literature. Abnormal deviation in the shape of sell turcica may have contributed to the variation in the length, depth, and diameter. A deviation in the size and shape of ST could be considered etiological factor in the development of malocclusion among Down syndrome individuals.

Sex determination through the evaluation of sella turcica measurements using head CT scan.

The estimation of age and sex is mandatory in forensic identification of unknown skeletal remains and it could be reached analyzing different bones' features. The morphometric evaluation of Sella turcica is less described in literature. Many studies have been published in this field for age estimation but none of them based on head CT scan measurement. Previous studies were carried out for age estimation on different populations, but any study has been carried out on the Italian population. Furthermore, no studies were carried out with CT scan technology for the correlation between sex and Sella turcica. Thanks to CT scan technology it has been possible to measure sella turcica's dimensions in an easier way than previous methods, to detect more accurate parameters and even introduce a new one. In this study, the sample was composed of 115 adults, 53 males, and 62 females. Five different measurements of the sellae turcicae were taken. The purpose of this study was to find new elements for sex assessment with the evaluation of sella turcica measurements, improving previous studies, analyzing an Italian European sample. In this study, results of the statistical analysis showed correlation between sex and sella turcica's parameter "Length of Sella Turcica" for which grater values are related to male gender. In conclusion, the Authors consider this unexpected result useful for sex determination in association with other parameters.

CORRELATION BETWEEN VERTICAL GROWTH PATTERNS OF THE JAWS AND SELLA TURCICA'S LINEAR DIMENSIONS USING CONE BEAM COMPUTED TOMOGRAPHY IN AN EGYPTAIN SUBPOPULATION.

Abstract: The sella turcica is one of the most important landmarks used by orthodontics in analysis of growth and treatment planning. Therefore, the purpose of this retrospective study was to detect whether there is a correlation between the sella turcica's linear dimensions and the vertical growth patterns of the jaws using CBCT in an Egyptian subpopulation. 144 CBCT scans of adult patients (68 males and 76 females) were taken from the archive of the Oral Radiology Department , Faculty of Dentistry, Suez Canal University. CBCT images were divided according to the vertical growth pattern of both maxilla and mandible into three groups; hypodivergent, normodivergent and hyperdivergent. The sella turcica diameter, length and depth were measured individually for each case. There were no statistically significant differences found between sella turcica's length and diameter measurements and vertical growth pattern of the jaws. While significant difference was found regarding the depth only between the three groups where the p-value was found to be 0.001. Conclusion: CBCT could be used as a highly accurate radiographic modality in assessing the linear dimensions of sella turcica .The sellar depth was the only linear measurement found to be affected by the vertical growth pattern of the jaws.

The Size of the Sella Turcica in Skeletal Class I, Class II, and Class III using FACAD Software- South Indian Population Study

Background: The sella turcica is a saddle-shaped bony structure in which anterior wall is formed by tuberculum sellae and posterior wall is formed by dorsum sellae. Lateral cephalometric landmark, sella, is of paramount importance in the field of orthodontics and dentofacial orthopaedics for diagnosis, treatment planning and assessment of skeletal maturation. * Significant literature is available indicating that large variations occur in the shape and size of sella turica among the three different types of skeletal malocclusion classes.* Studies have been conducted in different regions to evaluate the shape and size of sella turcica in different skeletal malocclusions therefore, the aim of this study is to describe the shape and measure the size of the sella turcica in south Indian subjects with different skeletal types. Materials and Methodology: Lateral cephalometric radiographs of 60 subjects (30 males and 30 females); 20 Class I, 20 Class II, and 20 Class III. The sella turcica on each lateral cephalometric was analysed using FACAD ortho software tracing to measure the linear dimensions of length, depth, and anteroposterior dimension. One-way analysis of variance was performed to study the relationship between skeletal type and sella size. Result: Skeletal class III subjects presented with a statistically significant difference in the depth of sella turcica on comparison with skeletal class II (p&gt;0.01). There was statistically insignificant difference found in the anteroposterior dimension and length of sella turcica in skeletal class I, class II and class III. Conclusion: When the size of sella turcica was compared with skeletal type, a statistically significant difference was found in depth skeletal Class II and Class III subjects.

Association between sella turcica bridging and congenitally missing maxillary lateral incisors

Background/purposeSella turcica bridging (STB) and its association with dental anomalies has been investigated and reported in literature. This is the first study that exclusively compared STB among the orthodontic patients with congenital missing maxillary lateral incisors (CMMLI) and individuals with complete dentition. Materials and methodsThe retrospective study has recruited 49 patients with CMMLI (13 males and 36 females aged between 12 and 43 years) and 49 patients with complete dentition. Sella dimensions and association of STB with CMMLI were evaluated and the results were analysed using descriptive and inferential statistics. ResultsThe comparison of mean diameter, length, and depth of sella between groups showed reduction in length among the CMMLI (p = 0.04). CMMLI group has shown a significant higher (p < 0.05) number of subjects (69.4%) with calcification when compared to control group (46.9%). The odds of having sella's bridging in patients with CMMLI were 2.5 times greater than patients with full set of teeth. Age showed a significant (p < 0.001) positive correlation with sella's width only in CMMLI. ConclusionPatients with CMMLI tend to have an increased frequency of STB, and decreased sella turcica length.

Morphology, Incidence of Bridging, Dimensions of Sella Turcica, and Cephalometric Standards in Three Different Racial Groups.

This study aims to assess the morphological appearance, incidence of bridging, linear dimensions of sella turcica and establish cephalometric standards in Bosnian, Chinese and Nepalese subjects. This retrospective study examined digital standardized lateral cephalograms of 540 subjects, which consisted of 116 females and 64 males with an age range of 8 to 28 years. The sella morphology, bridging, and size were analyzed on the lateral cephalograms. Steiner's and Rickett's analyses were performed on 270 subjects. Sella turcica presented a normal morphology in most Bosnian (86.7%), and Nepalese (90%) subjects whereas flat-shaped morphology was highly prevalent among Chinese subjects (36.7%). The frequency of full bridging was 7.2%, 2.8%, and 11.7% for Bosnian, Chinese, and Nepalese subjects, respectively. A significant correlation was detected between the length of sella turcica and gender of Bosnian subjects, whereas the size of sella turcica and gender of Chinese and Nepalese subjects were not affected. A direct correlation existed between age and size of sella turcica of Bosnian subjects. A significant correlation was detected between length and diameter of sella turcica and age in Chinese and Nepalese subjects. A statistically significant difference was found in length (P < 0.001), depth (P < 0.01) and diameter (P < 0.001) of sella turcica with race. The diameter of sella turcica was the only parameter significantly associated with race, gender and age. Significant differences were found between cephalometric norms in different racial groups. These findings assist orthodontists, neurosurgeons, and forensic medical investigatiors during orthodontic treatment planning, diagnosis of pathology of the pituitary gland, and age determination.

Correlation of linear dimensions of sella turcica with anteroposterior skeletal jaw relationship of Egyptian subjects using CBCT

The aim of this retrospective study was to find whether there is a correlation between the linear dimensions of the sella turcica and different anteroposterior skeletal growth patterns in an Egyptian population using CBCT. CBCT radiographs of 129 adult patients (60 males, 69 females) were retrieved from the archive of the radiology department of the Faculty of Dentistry, Suez Canal University. They were divided into three groups according to sagittal growth pattern and the sella turcica length, depth and diameter were measured for each case. No statistically significant differences were found between all sella turcica measurements and the anteroposterior jaw relationship. The p-values were 0.087, 0.007 and 0.998 for the diameter, depth and length respectively.

Association between sella turcica bridging and altered direction of dental eruption: A case-control study.

BackgroundCalcification between the anterior and posterior clinoid processes, also the so-called sella turcica bridging, has been associated in some studies with skeletal anomalies as well as with dental and eruption disturbances. It was hypothesized that sella turcica bridging was associated with an altered direction of dental eruption. The aim of the study was to assess whether there was a relationship between the degree of calcification and the presence or absence of an alteration in the tooth eruption direction.Material and MethodsA case-control multicenter study was conducted. The study population consisted of 150 subjects (age 10-50 years), 30 of which presented some type of alteration of the direction canine eruption (impactation or transposition) (cases) and 120 selected at random who did not present altered direction of dental eruption (controls). Cases and controls were matched by age, sex, and approximate date of starting orthodontic treatment. Lateral cephalometric radiographies were obtained and the extent of the sella turcica bridging was measured using a Vernier caliper and scored as no calcification, partially calcified, and completely calcified.ResultsThe frequency of a partially or completely calcified sella turcica bridge was significantly higher among cases with altered direction of dental eruption as compared with controls. There was a trend towards a shorter length of sella turcica in subjects with two or more canine eruption alterations. Sella turcica bridging was unrelated to sex, but it was significantly influenced by age.ConclusionsSella turcica bridging is frequently detected in subjects with altered direction of dental eruption of canines. Key words:Dental eruption, sella turcica bridging, anterior clinoid process calcification, posterior clinoid process calcification, cephalometric radiographs.

The morphology and bridging of the sella turcica in adult orthodontic patients

BackgroundThe 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.MethodsIt 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 and 20 females). The lateral cephalograms were traced and the sella turcica was assessed for its size, shape, and bridging.ResultsThe mean length, anteroposterior diameter and depth of sella turcica were 8.13 ± 2.03 mm, 9.60 ± 1.43 mm and 6.40 ± 1.21 mm respectively. The mean length of sella turcica was 7.91 ± 1.52 mm in Class I, 7.32 ± 1.62 mm in Class II and 9.16 ± .2.42 in Class III skeletal pattern; anteroposterior diameter was 9.30 ± 1.02 mm in Class I, 9.15 ± 1.28 mm in Class II and 10.35 ± 1.64 mm in Class III skeletal pattern; and the depth was 6.40 ± 0.92 mm in Class I, 6.07 ± 1.01 mm in Class II and 6.74 ± .1.54 mm in Class III skeletal pattern. There were significant differences in length and anteroposterior diameter and sella turcica between Class I, Class II and Class III skeletal patterns (p = 0.01), (p = 0.01) respectively. There was no significant difference in size of sella turcica between different genders and age groups. Sixty percent of the patients studied had normal Sella morphology. Partial Sella turcica bridging and Sella turcica bridging was seen in this study in 23.33% and 11.67% of patients respectively.ConclusionSixty percent of the patients had normal sella turcica. There were significant differences in lengths and anteroposterior diameters among Class I, Class II and Class III patients. The larger size was present in skeletal Class III patients.

Relationship Between Bridging and Dimensions of Sella Turcica and Antero-Posterior Skeletal Malocclusions in Children

Background: Interclinoid ligament calcification and dimensional changes in Sella Turcica seen on cephalometric radiographs are associated with some bone abnormalities as well as normal variations. Merging of anterior and posterior clinoid processes, known as Sella Turcica bridging or roofing and other changes in this area may occur as a part of large skeletal growth changes in body and may have association with craniofacial skeletal patterns development. Objectives: The aim of the present study was to compare Sella Turcica bridging and dimensions of patients with various skeletal patterns to investigate whether there is a correlation between Sella Turcica region changes with skeletal patterns or not, and on the other hand, to know if these changes could be used as predictive indices for growing patients skeletal patterns. Materials and Methods: A total of 108 cephalometric radiographs (36 Class I, 36 Class II, and 36 Class III) were randomly selected for evaluation. Sella Turcica was traced on acetate paper and scanned to produce digital images. The dimensions of Sella Turcica were measured with computer software using the Silverman, Kisling, and Axelsson method. To determine bridging, Leonardi’s method was employed. To determine the association of Sella Turcica bridging and dimensions with different malocclusions, chi-squared test and one-way ANOVA were used. Results: The means of Sella Turcica lengths in three groups were significantly different (P = 0.01). Mean depth and diameter, however, were not significantly different between malocclusions. In addition, bridging was not significantly different among three malocclusions evaluated. Conclusions: According to the results, mean length of Sella Turcica, rather than depth and diameter, was significantly associated with the type of malocclusion. Sella Turcica cavity length is larger in Cl III patients in comparison with Cl I ones and may have predictive value in some instances.

Correlation of Shape and Size of Sella Turcica With the Type of Facial Skeletal Class in an Iranian Group.

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 sella turcica and the type of facial skeletal class can help to make a more definitive decision for treatment plan.Objectives:The present study was designed to investigate this relationship in patients referred to a dental school in Iran.Patients and Methods:In this descriptive-analytical study, cephalometric radiographies of 90 candidates for orthodontic treatment (44 females and 46 males) with an age range of 14 - 26 years and equal distribution in terms of class I, class II, and class III facial skeletal classification were selected. The shape, length, diameter, and depth of the sella turcica were determined on the radiographs. Linear dimensions were assessed by one-way analysis of variance while the correlation between the dimensions and age was investigated using Pearson’s correlation coefficient.Results:Sella turcica had normal morphology in 24.4% of the patients while irregularity (notching) in the posterior part of the dorsum sella was observed in 15.6%, double contour of sellar floor in 5.6%, sella turcica bridge in 23.3%, oblique anterior wall in 20% and pyramidal shape of the dorsum sella in 11.1% of the subjects. In total, 46.7% of class I patients had a normal shape of sella turcica, 23.3% of class II patients had an oblique anterior wall and a pyramidal shape of the dorsum sella, and 43.3% of class III individuals had sella turcica bridge (the greatest values). Sella turcica length was significantly greater in class III patients compared to class II and class I (P < 0.0001). However, depth and diameter of sella turcica were similar in class I, class II, and class III patients. Furthermore, age was significantly correlated to the diameter of sella turcica as greater diameters were observed in older ages (P < 0.04).Conclusion:A significant relationship exists between the type of facial skeletal classification and the shape of the sella turcica; as in class III patients, sella turcica bridge was reported with a higher frequency. Also, sella turcica had a significantly higher length in these patients than in those with class I and class II facial skeletal types.

Sellar dimension in skeletal class II subjects with different growth patterns

ObjectivesThe purpose of this study was to evaluate and compare size and shape of the sella in skeletal class II subjects with normodivergent, hypodivergent and hyperdivergent growth patterns. Materials/methodsStandardized pre-treatment lateral cephalograms of 90 patients (45 males and 45 females) were selected based on values of five parameters. The sample consisted of 3 groups (normodivergent, hypodivergent and hyperdivergent) having 30 subjects each. The measurements included width, height, length and width/height (W/H) ratio. Student's t-test was used to calculate the differences in sella measurements among males and females of the same group, while one-way analysis of variance was used to determine the relationship between sella measurements and skeletal pattern. W/H ratio was used to assess the shape of the sella turcica. Values of W/H ratio were divided into 3 equal ranges: average, horizontally elongated or flat, and vertically elongated shapes. The shape of the sella turcica in groups was studied with the chi – square test and post-hoc analysis. ResultsThe results showed that the W/H ratio was maximum for hypodivergent and minimum for the hyperdivergent group. (p = 0.000). The average shape of sella turcica was most common among all the groups. No significant difference in mean sella turcica length, width and height was found between the groups. The sella turcica length in males of hypodivergent group was significantly higher as compared to the females of the same group (p = 0.038). Conclusions/implicationsSella turcica shape and dimensions can be used for the future studies as reference when comparing the same with the skeletal growth pattern.
