A new corrosion method (Aycan's method).

Background: As it is known, the anatomy of the vessels is examined by removing the cast of the vessels inside the organs. Generally, liquid material (polyester, takilon, etc.) is injected into the vessels with positive pressure to remove the cast from the vessels of the organs.

Anatomic and morphometric examination of auditory ossicles in sheep.

It is important to know the morphometry of the auditory ossicles for middle ear surgical applications. The present study aims to investigate the morphometric measurements of sheep auditory ossicles and the relationship between these ossicles. In this study, 100 malleus, incus and stapes of 50 Akkaraman sheep were examined using at trinocular stereo microscope and a total of 19 morphometric measurements were taken.

Effects of COVID-19 on brain and cerebellum: a voxel based morphometrical analysis.

Objective: COVID-19 is caused by SARS-CoV-2 virus and turned into a pandemic in a short time, affects many organs and systems, especially the nervous system. In the present study, it was aimed to determine the morphological and volumetric changes in cortical and subcortical structures in recovered COVID-19 patients.

Background: We think that COVID-19 has a long-term effect on cortical and subcortical structures.

A new supportive approach in the diagnosis of Chiari malformation type 1 in pediatric patients.

Purpose: Chiari malformation type 1 (CM-1) is a posterior fossa anomaly characterized by herniation of the cerebellar tonsils from the foramen magnum (FM). This study compares FM, medulla spinalis (MS), and herniated cerebellar tonsils ratios by making area measurements from axial plane MRI in CM-1 patients and the control group.

Methods: Our study evaluated 30 pediatric patients with CM-1 and 30 people in the control group.

Determining Knowledge Level, Attitude, Behaviors Regarding Vocal Hygiene and Use of Medical Drugs and Herbal Medicinal Products for Vocal Health in Second Level Professional Voice Users.

Objectives: This study aims to determine the knowledge level, attitude, and behaviors regarding vocal hygiene and use of medical drugs and herbal medicinal products for vocal health in second level professional voice users.

Methods: The study examined second level professional voice users comprised of amateur singers, religious officials,voice instructors and vocal coaches consisting of academicians working in conservatories and education faculties, music teachers, conservatory students majoring in opera or choir, students majoring in music education, and amateur actors who were reached via online platforms and were administered a 32-item questionnaire RESULTS: A total of 406 participants consisting of conservatory students (26.8%), religious officials (23.

An unique unilateral tendon variation of the extensor digitorum longus muscle.

Purpose: The double tendon of extensor digitorum longus (EDL) muscle was observed on the left leg of a 80-year-old male cadaver.

Methods: A male cadaver 80 years old was subjected to routine anatomical dissection for research and teaching purposes.

Results: The main tendon of the EDL muscle started just at the end of the muscle belly.

Anatomy of parotid gland and its secretory ducts in sheep.

Background: The parotid gland in sheep ends freely in front of the masseter muscle, and paracondylary section of occipital bone and extends deep until pterygoid extends of sphenoid bone and hyoid bone. The structure of salivary glands in mammals has been thoroughly studied using histological and sialographic method. This study aimed to reveal the detailed anatomic features and race-specific differences of the canal system of the parotid glands in Akkaraman sheep by using the corrosion cast technique.

A golden ratio for foramen magnum: an anatomical pilot study.

Background: The foramen magnum (FM) is an important landmark because of its close relationship to key structures such as the brainstem and spinal cord, an extension of the medulla oblongata. Because of the similarity in their shape, the existence of a relationship between cranial length and anteroposterior diameter of the FM, and between cranial width and transverse diameter of the FM may reveal the magnificent harmony of the skull and FM. Based on this idea, we investigated the existence of this harmony in skulls that we used in our study.

The morphology of the afferent and efferent domain of the sheep glomerulus.

Background: It is important to know the morphology of the glomerulus in order to explain kidney infiltration. The present study aims to research the morphology of afferent and efferent domains of sheep kidney glomeruli.

Materials And Methods: In this study, 2000 glomeruli from 20 kidneys of Akkaraman sheep were examined using the polyester resin method.

Comparison of three methods for the estimation of the pituitary gland volume using magnetic resonance imaging: a stereological study.

Stereological techniques using point counting and planimetry have been used to estimate pituitary gland volume. However, many studies have estimated pituitary gland volume by the mathematical approach the elliptic formula. The objective of the current study was to determine pituitary gland volume using stereological methods and elliptic formula on magnetic resonance imaging (MRI).

Outcome of dentigerous cysts treated with marsupialization.

Objective: The aim of this study was to evaluate the results of dentigerous cysts in children treated with marsupialization.

Study Design: 35 dentigerous cysts from 35 children treated with marsupialization were included in the study. The age of the children ranged from 8 to 13 years old.

Arteries of the carotid body in rats.

The arterial blood supply of 40 carotid bodies in 20 Wistar rats of both sexes, aged 10-12 weeks (250-350 g), was examined by light microscopy. The carotid bodies of all rats were supplied by only one carotid body artery. The average diameter of the carotid body arteries was 40 microns.

Measurements of axial length and radius of corneal curvature in the rabbit eye.

The axial length of the eye, the radius of the anterior corneal surface, and the diameter of the cornea were measured on 40 eyes of 20 New Zealand White rabbits. The ultrasonographic measurements of the axial length of the eye showed a mean value of 15.12 +/- 0.

Intradural disc herniations pathogenesis, clinical picture, diagnosis and treatment.

The relatively rare occurrence and uncertainty about pathogenesis of intradurally displaced disc herniations stimulated an anatomico-pathological study into intradural disc herniations. The relation between the ventral dura and posterior longitudinal ligament in the cervical, thoracic, lumbar and sacral regions were examined macroscopically and microscopically, and ventral and dorsal dural thickness was compared in 20 adult autopsies on patients who died from various causes; in addition, 20 late abortions and newborn cadavers were investigated in the same way. In this study, a total of 40 autopsies has shown that the ventral dura is most frequently and firmly attached to the posterior longitudinal ligament at the L4-L5 level and these adhesions may be congenital.
