  • Incidence Of Clavicular Rhomboid Fossa (impression For Costoclavicular Ligament) In The Brazilian Population: Forensic Application.
    2015
    Co-Authors: Prado F B, De Mello Santos L S, Caria P H F, Kawaguchi J T, Preza, D'o A G, Daruge Jnr E, Da Silva R F, Daruge E
    Abstract:

    In the last years, anthropology has been widely explored mainly when related to bones due to its morphologic characteristics, such as the Rhomboid Fossa of the clavicle. This study examined the incidence of the Rhomboid Fossa in paired clavicles of Brazilian subjects obtained from 209 adult bodies of known age and sex (107 males and 102 females) on which postmortem examinations had been performed by the senior author. The data were submitted to qualitative statistical analysis according to Fisher. There was a statistical difference (p= 5.98 x 10-23) between sexes related to the frequency of the Rhomboid Fossa. The Fossa was absent in 97,1% of the female clavicles and the incidence of bilateral Fossa was present in 2,9% of females. The incidence of bilateral Fossa was 29% for male clavicles. The sexual or side differences in the incidence of the Fossa could be found in this study, and qualitative analysis can corroborate sex determination of unidentified bodies in forensic medicine.2712-

  • endoscopic opening of the foramen of magendie using transaqueductal navigation for membrane obstruction of the fourth ventricle outlets technical note
    Journal of Neurosurgery, 2006
    Co-Authors: Pierluigi Longatti, Alessandro Fiorindi, Alberto Feletti, Vittorio Baratto
    Abstract:

    A membrane obstruction of the foramina of Magendie and Luschka is an uncommon origin of hydrocephalus characterized by unusual clinical symptoms of Rhomboid Fossa hypertension. Various surgical approaches have been proposed to alleviate this obstruction, including opening the obstructed foramen of Magendie using suboccipital craniectomy, shunting procedures, and more recently, endoscopic third ventriculostomy (ETV). In some cases, however, reshaping of the posterior Fossa due to the collapse of the prepontine cistern could make ETV difficult for the surgeon and dangerous to the patient. In these cases, endoscopic opening of the foramen of Magendie by transaqueductal navigation of the fourth ventricle is a suitable and feasible therapeutic option.

  • Inter- and Intrapatient Variability of Facial Nerve Response Areas in the Floor of the Fourth Ventricle
    Operative Neurosurgery, 2011
    Co-Authors: Helmut Bertalanffy, Nadir Tissira, Niklaus Krayenbühl, Oliver Bozinov, Johannes Sarnthein
    Abstract:

    Abstract BACKGROUND: Surgical exposure of intrinsic brainstem lesions through the floor of the 4th ventricle requires precise identification of facial nerve (CN VII) fibers to avoid damage. OBJECTIVE: To assess the shape, size, and variability of the area where the facial nerve can be stimulated electrophysiologically on the surface of the Rhomboid Fossa. METHODS: Over a period of 18 months, 20 patients were operated on for various brainstem and/or cerebellar lesions. Facial nerve fibers were stimulated to yield compound muscle action potentials (CMAP) in the target muscles. Using the sites of CMAP yield, a detailed functional map of the Rhomboid Fossa was constructed for each patient. RESULTS: Lesions resected included 14 gliomas, 5 cavernomas, and 1 epidermoid cyst. Of 40 response areas mapped, 19 reached the median sulcus. The distance from the obex to the caudal border of the response area ranged from 8 to 27 mm (median, 17 mm). The rostrocaudal length of the response area ranged from 2 to 15 mm (median, 5 mm). CONCLUSION: Facial nerve response areas showed large variability in size and position, even in patients with significant distance between the facial colliculus and underlying pathological lesion. Lesions located close to the facial colliculus markedly distorted the response area. This is the first documentation of variability in the CN VII response area in the Rhomboid Fossa. Knowledge of this remarkable variability may facilitate the assessment of safe entry zones to the brainstem and may contribute to improved outcome following neurosurgical interventions within this sensitive area of the brain.

  • Computational Macroscopical Patterning Of The Medullary Striae Of Fourth Ventricle
    2015
    Co-Authors: Batigalia F., Boer N.p., Bankoff A.d.p., Simonato L.e., Boer A.l.r., Chacon E.
    Abstract:

    The aim of this study was to pattern macroscopically, by use of computational tools, the number and distribution of the medullary striae (MS) of fourth ventricle. After removing 71 fresh human brain stems, each respective Rhomboid Fossa was photographed. The MS were carefully identified to be shaped and fulflled by means of a digital pen, using the Adobe Photoshop CS3® program. For absolute and relative analyses of number and distribution, it was considered the maximum and minimum numbers of striae; striae that reached the ipsilateral lateral recess; presence of horizontal or oblique striae, with or without parallelism; and striae located at pontine or bulbar part of the Rhomboid Fossa. At least two MS per side were macroscopically detectable in 90.6% of cases; they were bilaterally absent in 5.3% of pieces; and at least one medullary stria was present in both sides of the Rhomboid Fossa in 92% of cases. As on the right side (36% of cases) as on the left (26.6%), two MS were frequently more present. In 60% of cases, striae reached ipsilateral lateral recess on the left, and in 40% of cases on the right. It was detected horizontal, (non-parallel) oblique and parallel striae in 50.7, 86.7 and 26.7% of cases, respectively. Medial medullary striae were observed in the bulbar part of Rhomboid Fossa in 80% of pieces, and in 36% of cases in the pontine part. The MS of fourth ventricle show high morphological variability degree in relation to number and distribution.263-4135140(2008) Department of Molecular and Cell Biology: Glossary, , www.http://mcb.berkeley.edu/courses/mcb160L/Handouts_2006/Glossary, UNIVERSITY OF CALIFORNIA, California, 2008(2001) Anatômica Da Sociedade Brasileira De Anatomia: Terminologia Anatômica, pp. 136-138. , COMISSÃO DE TERMINOLOGIA, São Paulo: Manole(1998) International Anatomical Terminology, (115), p. 113. , INTERNATIONAL FEDERATION OF ASSOCIATIONS OF ANATOMISTS-IFAA. 1 ed.
