AI Article Synopsis
- The study investigates the size and shape variations of the sella turcica, a bone structure visible in lateral cephalograms, aimed at developing a new index for gender determination.
- It analyzed 80 lateral cephalograms from individuals aged 10-30, measuring sella turcica dimensions and introducing a novel Sella Turcica Index (STI).
- Results showed significant gender-related differences, with higher perimeter and depth in females and a greater mean STI in males, indicating the potential use of STI in forensic identification.
Article Abstract
Unlabelled: Background: The sella turcica is a structure readily seen on lateral cephalograms and sella point is routinely traced for various cephalometric analyses. The aim of the present study was to evaluate the morphometric variation in size and shape of sella turcica via lateral cephalogram. The objectives were to introduce a novel sella turcica index (STI) and assess its reliability that could be helpful in gender determination. Materials and Methods: A total of 80 lateral cephalograms of the patients of age group 10-30 years were included for the study. The morphological variations of the sella turcica was done based on the classification given by Axelsson et al. (2004). The length, depth and perimeter of the sella turcica was measured and STI derived and calculated. The data was further subjected to discriminant analysis to validate the gender outcome. Reliability of the novel index was determined by calculating the sensitivity and specificity. Results: The overall most common morphological type of sella turcica was Type A (56.25%) followed by Type B (18.75%) and Type E (13.75%). The mean perimeter and depth of sella turcica was higher in females whereas the mean length of sella turcica was higher in males. The mean STI was higher in males and statistically highly significant. The sensitivity and specificity of this index was 72.5% and 90% respectively. Conclusion: A significant relationship was observed between the morphometric measurements of sella turcica and gender. STI could be of great help as a reliable tool for personal identification in forensic sciences.

Objectives: This study aims to compare the effects of two orthodontic treatment modalities for skeletal class Ⅲ malocclusion on specific changes in airway volume, morphology, palatal angle, mandibular rotation, and bone displacement. Results provide scientific evidence for the selection of orthodontic treatment plans and reduce the risk of developing obstructive sleep apnea hypopnea syndrome (OSAHS).
Methods: Thirty-six patients diagnosed with skeletal class Ⅲ malocclusion at the Department of Orthodontics, the Affiliated Stomatological Hospital of Nanjing Medical University from September 2018 to December 2023 were divided into two groups: orthodontic-orthognathic treatment group (18 patients) and camouflage orthodontic treatment group (18 patients).
Aim: The aim of this retrospective study was to investigate the morphology of sella turcica (ST) in Chiari malformation type I (CM-I) using computed tomography.
Material And Methods: The size and shape of ST were examined using the radiological images of 32 CM-I patients (21 women/11 men, mean age: 26.09 ± 15.

Empty sella (ES) is a radiographic finding defined by the presence of cerebrospinal fluid in the sella turcica, with associated compression of the pituitary gland. Empty sella syndrome (ESS) is the combination of this radiographic finding with endocrine, ophthalmological, and/or neurological symptoms. The focus of this literature review is to synthesize information about asymptomatic or incidental ES specifically, meaning the radiologic finding of an empty sella without symptoms.

We discuss a case of a 19-year-old female who presented with pressure headaches and progressive vision loss. In the emergency department, a series of diagnostic tests were conducted, including CT, MRI, and lumbar puncture with measurement of opening pressure. All these examinations yielded results consistent with the suspected diagnosis of idiopathic intracranial hypertension (IIH).

Purpose: Studies focused on the effects of sellar and/or perisellar (S/PS) meningiomas on pituitary function are scarce. The primary objective of the present study was to determinate the effects that S/PS meningiomas and their treatments have on pituitary function. Also, we described the clinical characteristics and therapeutic outcomes of the cohort of adult Spanish patients.
