Aim: There are more than 100 different clinical pathologies that affect the orbit, originating from the orbit or surrounding structures. Various surgical approaches have been described to solve this number of lesions. To date, there have been few evaluations of research productivity in the field of orbital surgery.

The infraorbital foramen (IOF) is a key reference point on the face, as the infraorbital nerve, which passes through it, is distributed across the face and provides sensation to important structures of midface region. The objective of this study is to conduct a morphometric analysis of the IOF in 3 dimensions. CBCT images of 92 individuals (50 females and 42 males) aged between 18 and 60 years were taken and transferred to the 3D Slicer program, and 3D images were obtained.

Alzheimer's disease is a chronic complex neurodegenerative disease characterized with amyloid plaques and loss of neurons. TGF-β1 is important growth factor, plays critical roles in cell metabolism, tissue homeostasis, neuronal development, and synaptic plasticity. In this study, we aimed to examine the effect of TGF-β1 on the regulation of α, β, and γ-secretase enzymes, Aβ-40 accumulation, apoptosis, and neuronal damage in an experimental Scopolamine-induced AD-like model.

The present paper was designed to analyze the dimensions of such important bony structures and surgical landmarks, which are used by many clinicians in many surgical interventions, in dry skull, cadaver, and healthy subjects on computed tomography (CT) images, and to determine whether there is a significant difference between these methods, and to obtain reference values from 3 different methods. Eight cadavers and 16 dry skulls and 100 three-dimensional (3D) CT images were studied. Necessary permissions for the study were obtained from Ethics Comittee.

Background: Piriformis syndrome, which is seen as the cause of 0.3% to 6% of low back pain, is a painful condition that occurs as a result of compression of the piriformis muscle on the sciatic nerve. Although there are many studies in the literature about piriformis syndrome, no bibliometric analysis has been found.

It is important to investigate the changes in the masseter muscle, one of the chewing muscles, in epilepsy patients and to determine whether epilepsy can be effectively predicted on muscle. The aim of this study is to measure masseter muscle thickness, circumference and cross-sectional area in individuals with epilepsy and healthy individuals. This study was performed with 128 individuals (64 epilepsy patients and 64 healthy subjects) aged between 18 to 59 years.

The study aimed to compare the morphometric and morphologic analyses of the bone structures of temporomandibular joint and masticatory muscles on Cone beam computed tomography (CBCT) in 62 healthy subjects and 33 subjects with temporomandibular dysfunction (TMDS) aged between 18 and 56 years. In addition, a machine learning (ML) pipeline involving the Random Forest classifier was used to automatically detect TMDS. Thirty parameters (including age and gender) associated with the condylar process, articular tubercle, mandibular fossa, ramus mandible, joint space, and masticatory muscles were examined using CBCT.

Article Synopsis
  • Epilepsy is a common chronic brain disease with genetic roots, and this study aims to analyze facial measurements in both epilepsy patients and healthy individuals to find characteristics that might influence epilepsy diagnosis.
  • The research included 120 epilepsy subjects and 60 healthy controls, measuring different facial angles and lengths using CT scans to compare the two groups.
  • The results indicated specific facial measurements were significantly different in epilepsy patients, suggesting that epilepsy may influence certain facial features, though no age-related changes were observed in healthy subjects.

This study aimed to investigate the significance of publications examining the effectiveness of cadaver studies in the field of medicine with the method of bibliometric analysis, which emerged in the 1950s, offers the opportunity to conduct a detailed analysis of a specific subject, just like a systematic literature review or meta-analysis. Also, it aimed to enlighten the content of cadaver studies in the last half-century and to present a perspective for the future. In the study, an advanced search was conducted on the Web of Science Core Collection database on August 1, 2023, using the keywords "cadaver," "cadaver study," "cadaveric dissection.

This paper determined the morphometric measurements' reference values and relationship of the optic nerve and cranium in Turkish healthy individuals according to age and sex. Five hundred fifty-nine (280 females and 279 males) patients aged from 2 to 90 years were included in this study. The measurements were taken from patients having brain magnetic resonance images in sagittal, axial, and coronal sections in the radiology department.

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.

Peripheral nerve injury (PNI) is a major health problem that results in loss of motor and sensory functions. In treatment of PNI, various methods such as anastomosis, nerve grafts, nonneural tissue grafts, and nerve conduits are applied. In the present study, it was aimed to investigate the effects of Theranekron and Alpha-lipoic acid (ALA) combined treatment on nerve healing in experimental PNI by using histomorphometric, electron microscopic, immunohistochemical and molecular biological methods.

Background And Objective: This study determined the hand muscle strength parameters and reference values in healthy subjects using the Nicholas Manual Muscle Tester (NMMT) and Manual Muscle Test (MMT) and compared these methods.

Methods: The study was carried out with 200 (102 males, 98 females) healthy adults aged between 18-25 years. Muscle strength evaluations of the hand were performed to determine hand motor ability using both NMMT and MMT.

Objective: The aim of this study was to determine the prerequisite physical features of classical ballet education.

Methods: Students who enrolled and were rejected for the applications of State Conservatory Ballet Main Art Branch in the academic year 2013-2014 and 2014-2015 were compared with their exam results. This study involves defining the physical ability and determining physical fitness by using Eurofit tests including the Flamingo Balance test (FB), Plate Tapping (PT), Sit and Reach (SITR), Standing Broad Jump (SBJ), Handgrip test (HG), Sit Up in 30 Seconds (SU) and Shuttle Run 10 × 5 meter (SR), Heath-Carter somatotyping method and anthropometric measurements which determine ballet students' body type and physical abilities.
