Background/Aim: Carpal tunnel is an important anatomical passage that carries the flexor tendons into the hand. As there is still no consensus about its contents among the anatomy textbooks, the main purpose of this study was to identify the relations of the flexor carpi radialis tendon in the carpal tunnel. Materials and methods: This retrospective study was completed in April 2018 at authors' university's hospital. Seventy-four female and 44 male patients' wrists without any pathology were examined by using magnetic resonance images. The series of axial sections where the pisiform exist were evaluated by using T1 sequence and the structures in the carpal tunnel were identified. Results: Results of this study showed that the tendon of the flexor carpi radialis was found above the flexor retinaculum within its own septal compartment in all patients. Conclusion: According to the results, tendon of flexor carpi radialis crosses the wrist region superficial to the carpal tunnel. Thus, tendon of flexor carpi radialis doesn't have any effect on the carpal tunnel syndrome. Further cadaveric studies would be useful for identifying the contents of the carpal tunnel and morphological organization of the wrist.

Aim: For reliable diagnosis and surgical approach, a fundamental knowledge of the normal anatomy and the morphometric measurements of the skull base are important to the clinicians. The aim of this study is to evaluate the morphometric dimensions of Foramen Magnum (FM) and clivus with respect to the related structures of Turkish population. Material and Method: 313 patients' computed tomography angiography (CTA) image series of head and neck region was examined retrospectively. Length of the clivus (LoC), angle between the clivus and posterior margin of FM (C-FM), angle between the line along the posterior surface of the clivus and the other line along the posterior side of the dens of axis (C-D), antero-posterior diameter of the FM (FMap), largest transvers distance between lateral margins of the FM (FMt) and the area of the FM (FMa) were measured.

Background: Rima glottidis and cricoid cartilage are important parts for laryngeal passage. However, their complex anatomical organizations give rise to occur some difficulties during intubation or surgeries. Therefore, these anatomical structures have great risk of damage during these procedures. The main aim of this study is to evaluate detailed morphometric properties of these critical parts of the larynx. Methods: In this study, 74 female and 76 male patients', without any pathology in their laryngeal and neck regions, computed tomography images were examined, retrospectively. Anteroposterior diameter of the supraglottic region immediately above the vocal folds, anterior angle of the vocal folds, transverse diameter of the rima glottidis and anteroposterior and transverse diameters of the cricoid cartilage were measured using Osirix-Lite version 9. Results: Transverse diameter of the cricoid cartilage was found less than 1 cm, however, the transverse diameter of the rima glottidis was significantly smaller. All variables except for anterior angle of the vocal folds were higher in men than women. Conclusions: The transverse diameter of the rima glottidis was the narrowest part of the laryngeal passage. The physicians should be aware of this part of the larynx besides the cricoid cartilage during endotracheal tube administrations.
