Association between vertebral artery dominance and basilar artery curvature in migraineurs: an anatomical magnetic resonance imaging study.

Background And Purposes: Numerous studies demonstrate a link between cerebrovascular alterations and migraine pathogenesis. We investigated the association between migraine and vertebral artery dominance (VAD), basilar artery (BA) curvature, and elongation.

Materials And Methods: This cross-sectional MRI study included 74 migraine patients and 74 control subjects aged between 18 and 55 years.

Surgical landmarks for identification and preservation of the internal branch of the superior laryngeal nerve.

Objective: To determine the topographical anatomic features of the internal branch of the superior laryngeal nerve (ibSLN) at the thyrohyoid membrane entrance area in relation to certain consistent anatomical structures.

Materials: METHODS: Twenty-two fresh adult head cadavers (9 male, 13 female; age range 52-95 years) with no signs of abnormality in the neck were dissected to determine the anatomic relationship of ibSLN and superior border of thyroid cartilage, thyroid notch, carotid bifurcation, hyoid corpus, and hyoid greater cornu.

Results: The topographical relationship between ibSLN and superior border of thyroid cartilage, thyroid notch, carotid bifurcation, hyoid corpus, and hyoid greater cornu was identified bilaterally in all cadavers.

Preoperative and postoperative high angular resolution diffusion imaging tractography of cerebellar pathways in posterior fossa tumors.

This study aimed to utilize high angular resolution diffusion magnetic resonance imaging (HARDI) tractography in the mapping of the pathways of the cerebellum associated with posterior fossa tumors (infratentorial neoplasms) and to determine whether it is useful for preoperative and postoperative evaluation. Retrospective data from 30 patients (age 2-16 yr) with posterior fossa tumor (17 low grade, 13 high grade) and 30 age-sex-matched healthy controls were used. Structural and diffusion-weighted images were collected at a 3-tesla scanner.

Morphometric Development of the Mandible in Fetal Cadavers.

Purpose: The aim of this study is to present reliable data by measuring the morphometric properties of the mandible in the fetal period.

Methods: A study was performed on mandibles of 35 fetuses (18 male fetuses and 17 female fetuses), aged between 21 and 40 weeks of gestation. Fetuses were examined in 3 groups according to their developmental stages: 2nd trimester, 3rd trimester, and full-term.

Morphometric development of the tongue in fetal cadavers.

Purpose: The tongue is a specific organ for the sense of taste. It consists of the striated muscle and mucous membrane. Furthermore, it helps the functions of speech, chewing, and swallowing.
