Objective This study aims to determine the topographic localization of the stylomastoid foramen (SF) and its morphometric relationship with the surrounding bony landmarks. Design A descriptive anatomical study. Setting Anatomy Laboratory of the Faculty of Medicine. Participants Measurements were performed on 53 dry temporal bones. Main Outcome Meas...

Hair whorl direction and handedness were stated to have a common genetic basis in the random recessive model. This study was carried out with a total of 317 healthy young males. The association between hair whorl swirling direction and handedness, footedness and eyedness were assessed. The direction of hair whorl was clockwise at a rate of 76.7%, a...

The azygos system veins vary greatly in their mode of origin, course, tributaries, anastomoses and termination. Therefore, we aimed to investigate the types of azygos system in this study. Our research was made in Anatomy departments on 48 conserved cadavers aging between 27-70 years, of which 35 were males and 13 females. In the research, the diam...

Objective: Measurement of disc height has various clinical implications. Radiographic measurement of disc height may present inaccurate results and its direct “surgical” confirmation has not been studied. This study aimed to evaluate the agreement between the radiographic and post-discectomy surgical measurements of human intervertebral discs’ heig...

Aim: To investigate the disc-capsule complex and condyle attachments of the lateral pterygoid muscle and its variations. Materials and methods: Forty-nine temporomandibular joint (TMJ) specimens were used, obtained from 26 human cadavers. The insertion point of each muscle head was determined. The widths and lengths of the heads were measured. Resu...

It is well known that formaldehyde (FA) is cytotoxic and potentially carcinogenic. Although the individual effects of this reactant on cells has been investigated, the cytotoxicity exerted by the coexistence of FA is poorly understood. The aim of this study was to investigate the effects of FA on the liver in rats, by light and electron microscopic...

The inferior alveolar nerve is the one of the large branches of the mandibular division of the trigeminal nerve. It is vulnerable during surgical procedures of the mandible. Despite its importance, no anatomical and histological examination has been conducted to provide a detailed cross-sectional morphology of the mandibular canal according to dent...

Bilateral arcus axillaris was found on a 55-yearold male cadaver in our laboratory of anatomy during routine dissection. This variation which is also called as axillary arch, axillopectoral muscle or axillary arch of Langer could be fibromuscular or muscular. In our case, a fasciculus separating from latissimus dorsi muscle ended at the tendon of p...

Objectives: Anatomical dimensions of lateral ulnar collateral and annular ligaments were determined in the present study.Patients and Methods: These measurements were performed on 20 elbows from 10 cadavers. Lateral ulnar collateral and annular ligaments were dissected in all elbows and their anatomical lengths and widths were measured.Results: The...

The aim of this prospective study is to evaluate the differences in the ability to view structures in the middle ear between Tos modified canal wall-up mastoidectomy and classic canal wall-up (CWU) and canal wall-down (CWD) mastoidectomies. Eighteen temporal bones of 10 cadaver heads were used. Six bones were randomly selected for each surgical tec...

To investigate and evaluate the prevalence of 4 kinds of synovial plicae named according to patella, which are inferior, medial, lateral and superior. We evaluated plicae in 318 knee arthroscopies through video records, obtained from January 1994 to December 2002 in the Arthroscopy Unit, Department of Orthopedic Surgery, Faculty of Medicine, Trakya...

Variations seen in the thoracic vein system are related to the development of these veins. During the dissection from the posterior mediastinum of the 60-year-old male cadaver, it was observed that there was no complete accessory hemiazygos vein, and both posterior intercostal veins and hemiazygos vein (above T10 level) drained bilaterally to the a...

The aim of this study was to determine number of ocular vortex veins, their scleral coordinates, and their relationship with nearby extraocular muscles. Sixty intact cadaver orbits having no history of eye or orbital disorders during life were carefully dissected under stereomicroscopic magnification to expose vortex veins and their exit sites from...

The aim of this study was to examine the existence of the extensor indicis et medii communis in detail. Thirty-one randomly selected adult cadavers (62 upper extremities) were examined for this project (22 males and 9 females between the ages 38 and 87). The muscle was observed in 3 of 62 hands, an incidence of 4.8%. One was in the right and the ot...

To study the anatomical dimensions of the anterior bundle of ulnar collateral ligament and its role in elbow instability. We studied 20 elbows of 10 cadavers. Anterior bundle of ulnar collateral ligament was dissected in all elbows and its anatomical length and width were measured. After measuring it, we assessed the role of the anterior bundle of...

During routine dissections, we observed the subclavius posticus muscle in the cervical region. This muscle was on the left side and innervated by a branch of suprascapular nerve. The omohyoid muscles and the subclavius muscles were normal. The anomaly observed in this dissection should be considered as neural or vascular compression syndromes.

In this study, we aimed to investigate the muscular bridge between the inferior oblique (IO) and inferior rectus (IR) muscles of the eye. Cohort study. The orbits of sixty intact cadavers with no history of eye muscle or orbital disorders during life were carefully dissected to expose the muscular bridge between the IO and IR muscles. Numbers of th...

Ulnar artery originating from brachial artery higher and coursing superficially was found at the left upper extremity of a male cadaver during routine dissection. The branch originating from the brachial artery at the middle part of the arm reached the elbow at the medial part of this artery. At the elbow region it reached the forearm by crossing i...

The musculus extensor digiti medii proprius and musculus extensor digitorum brevis manus are anomalous extensor muscles of the hand. During the routine dissection of a white male cadaver a musculus extensor digiti medii proprius was seen on both hands and a musculus extensor digitorum brevis manus was seen on the left hand. The extensor medii propr...

The superficial brachial artery, an anatomical variation of the brachial artery, is usually located anterior to the aponeurosis of the biceps muscle in the forearm. Since it may be mistaken for the cubital vein, it may pose severe problems on intravenous injections. This case report illustrates findings of the superficial brachial artery encountere...

During the dissection of a 48-year-old male cadaver, the left gastric artery was observed directly originating from the abdominal aorta. An unusual embryologic development of the ventral splanchnic arteries may lead to considerable variations. The rare occurrence of this variation is stated to be 0.5%-15%. This case of the left gastric artery is de...
