Benmoussa1,2 · F. Crampon3,4 · A. Fanous5 · P. Charlier1,6 Received: 5 March 2019 / Accepted: 22 June 2019 / Published online: 28 June 2019 © Springer-Verlag France SAS, part of Springer Nature 2019 Abstract Introduction In the following article, we are presenting a clinical observation of Baron Larrey. In 1804, Larrey was the inspector general of health, as well as the chief surgeon of the imperial Napoleonic Guard. He participated in all of Napoleon’s campaigns. A paleopathological study was performed on a skull from Dupuytren’s Museum (Paris) with a long metal stick in the head. We report here a clinical case as well as the autopsy description of this soldier’s skull following his death. We propose a diferent anatomical analysis of the skull, which allowed us to rectify what we believe to be an anatomical error and to propose varying hypotheses regarding the death of soldier Cros. Materials and methods The skull was examined, observed and described by standard paleopathology methods. Measure- ments of the lesion were performed with metric tools and expressed in centimeters. Historical research was made possible through the collaboration with the Museum of Medicine History-Paris Descartes University. Results Following the above detailed anatomical analysis of the path of the metal rod, we propose various possible lesions in soldier Cros due to the accident. At the inlet, the frontal sinuses could have been damaged.

The measurements on digital radiography are quite acceptable and reliable for clinical use as long as the structures do not traverse the midline. Repeated measurements lead to a reduction in the systematic error and magnification to a loss of accuracy. The study was planned on the Department of Dentistry Anugrah Narayan Magadh Medical College and Hospital, Gaya.on 30 implants in the posterior mandibular regions. The digital panoramic radiographic images were taken using implants in the posterior mandibular regions. The digital panoramic radiographic equipment used. All digital panoramic radiographs were taken by technicians according to standard protocol provided by the manufacturer. This study is aimed to determine the accuracy of the vertical and horizontal measurements on digital panoramic radiographic images using implants in the posterior mandibular regions.

  • Direct Sagittal CT in the Evaluation of Temporal Bone Disease
    371 Direct Sagittal CT in the Evaluation of Temporal Bone Disease 1 Mahmood F. Mafee The human temporal bone is an extremely complex structure. Direct axial and coronal Arvind Kumar2 CT sections are quite satisfactory for imaging the anatomy of the temporal bone; Christina N. Tahmoressi1 however, many relationships of the normal and pathologic anatomic detail of the Barry C. Levin2 temporal bone are better seen with direct sagittal CT sections. The sagittal projection Charles F. James1 is of interest to surgeons, as it has the advantage of following the plane of surgical approach. This article describes the advantages of using direct sagittal sections for Robert Kriz 1 1 studying various diseases of the temporal bone. The CT sections were obtained with Vlastimil Capek the aid of a new headholder added to our GE CT 9800 scanner. The direct sagittal projection was found to be extremely useful for evaluating diseases involving the vertical segment of the facial nerve canal, vestibular aqueduct, tegmen tympani, sigmoid sinus plate, sinodural angle, carotid canal, jugular fossa, external auditory canal, middle ear cavity, infra- and supra labyrinthine air cells, and temporo­ mandibular joint. CT has contributed greatly to an understanding of the complex anatomy and spatial relationship of the minute structures of the hearing and balance organs, which are packed into a small pyramid-shaped petrous temporal bone [1 , 2]. In the past 6 years, high-resolution CT scanning has been rapidly replacing standard tomography and has proved to be the diagnostic imaging method of choice for studying the normal and pathologic details of the temporal bone [3-14].

  • A Morphological Study of Jugular Foramen
    Vikas. C. Desai et al /J. Pharm. Sci. & Res. Vol. 9(4), 2017, 456-458 A Morphological Study of Jugular Foramen Vikas. C. Desai1, Pavan P Havaldar2 1. Asst. Prof, Department of Dentistry, BLDE University’s,Shri. B. M. Patil Medical College Hospital and Research Centre,Bijapur – 586103, Karnataka State. 2. Assistant Professor of Anatomy, Gadag Institute of Medical Sciences, Mallasamudra, Mulgund Road, Gadag, Karnataka, India. Abstract Jugular foramen is a large aperture in the base of the skull. It is located behind the carotid canal and is formed by the petrous part of the temporal bone and behind by the occipital bone. The jugular foramen is the main route of venous outflow from the skull and is characterised by laterality based on the predominance of one of the sides. Sigmoid sinus continues as internal jugular vein in posterior part of jugular foramen. Ligation of the internal jugular is sometimes performed during radical neck dissection with the risk of venous infarction, which some adduce to be due to ligation of the dominant internal jugular vein. It is generally said that although the Jugular foramen is larger on the right side compared to the left, its size as well as its height and volume vary in different racial groups and sexes. The foramen’s complex shape, its formation by two bones, and the numerous nerves and venous channels that pass through it further compound its anatomy. The present study was undertaken in 263(526 sides) different medical and dental institutions in Karnataka, India. Out of 263 skulls in 61.21% of cases the right foramina were larger than the left, in 13.68% of cases the left foramina were larger than the right and in 25.09% cases were equal on both sides.

    Ossification Defects and Craniofacial Morphology In Incomplete Forms of Mandibulofacial Dysostosis A Description of Two Dry Skulls ERIK DAHL, D.D.S., DR. ODONT. ARNE BJORK, D.D.S., ODONT. DR. Copenhagen, Denmark The morphology of two East Indian dry skulls exhibiting anomalies which were suggested to represent incomplete forms of mandibulofacial dysostosis is described. Obvious although minor ossification anomalies were found localized to the temporal, sphenoid, the zygomatic, the maxillary and the mandibular bones. The observations substantiate the concept of the regional and bilateral nature of this malformation syndrome. Bilateral orbital deviations, hypoplasia of the malar bones, and incomplete zygomatic arches appear to be hard tissue aberrations which may be helpful in exami- nation for subclinical carrier status. Changes in mandibular morphology seem to be less distinguishing features in incomplete or abortive types of mandibulofacial dysostosis.

  • Surgical Anatomy of the Juxtadural Ring Area
    Surgical anatomy of the juxtadural ring area Susumu Oikawa, M.D., Kazuhiko Kyoshima, M.D., and Shigeaki Kobayashi, M.D. Department of Neurosurgery, Shinshu University School of Medicine, Matsumoto, Japan Object. The authors report on the surgical anatomy of the juxtadural ring area of the internal carotid artery to add to the information available about this important structure. Methods. Twenty sides of cadaver specimens were used in this study. The plane of the dural ring was found to incline in the posteromedial direction. Medial inclination was measured at 21.8š on average against the horizontal line in the anteroposterior view on radiographic studies. Posterior inclination was measured at 20.3š against the planum sphenoidale in the lateral projection, and the medial edge of the dural ring was located 0.4 mm above the tuberculum sellae in the same projection. The lateral edge of the tuberculum sellae was located 1.4 mm below the superior border of the anterior clinoid process. The carotid cave was situated at the medial or posteromedial aspect of the dural ring; however, two of the 20 specimens showed no cave formation. The carotid cave contained the subarachnoid space in 13 sides, the arachnoid membrane only in three sides, and the extraarachnoid space in two sides. The authors propose that the marker of the medial side of the dural ring, which is more proximal than the lateral, is the tuberculum sellae in the lateral view on radiographic studies. In the medial aspect of the dural ring the intradural space can be situated below the level of the tuberculum sellae because of the existence of the carotid cave.

  • Chapter 2 Implants and Oral Anatomy
    Chapter 2 Implants and oral anatomy Associate Professor of Maxillofacial Anatomy Section, Graduate School of Medical and Dental Sciences, Tokyo Medical and Dental University Tatsuo Terashima In recent years, the development of new materials and improvements in the operative methods used for implants have led to remarkable progress in the field of dental surgery. These methods have been applied widely in clinical practice. The development of computerized medical imaging technologies such as X-ray computed tomography have allowed detailed 3D-analysis of medical conditions, resulting in a dramatic improvement in the success rates of operative intervention. For treatment with a dental implant to be successful, it is however critical to have full knowledge and understanding of the fundamental anatomical structures of the oral and maxillofacial regions. In addition, it is necessary to understand variations in the topographic and anatomical structures among individuals, with age, and with pathological conditions. This chapter will discuss the basic structure of the oral cavity in relation to implant treatment. I. Osteology of the oral area The oral cavity is composed of the maxilla that is in contact with the cranial bone, palatine bone, the mobile mandible, and the hyoid bone. The maxilla and the palatine bones articulate with the cranial bone. The mandible articulates with the temporal bone through the temporomandibular joint (TMJ). The hyoid bone is suspended from the cranium and the mandible by the suprahyoid and infrahyoid muscles. The formation of the basis of the oral cavity by these bones and the associated muscles makes it possible for the oral cavity to perform its various functions.

  • Lab Manual Axial Skeleton Atla
    1 PRE-LAB EXERCISES When studying the skeletal system, the bones are often sorted into two broad categories: the axial skeleton and the appendicular skeleton. This lab focuses on the axial skeleton, which consists of the bones that form the axis of the body. The axial skeleton includes bones in the skull, vertebrae, and thoracic cage, as well as the auditory ossicles and hyoid bone. In addition to learning about all the bones of the axial skeleton, it is also important to identify some significant bone markings. Bone markings can have many shapes, including holes, round or sharp projections, and shallow or deep valleys, among others. These markings on the bones serve many purposes, including forming attachments to other bones or muscles and allowing passage of a blood vessel or nerve. It is helpful to understand the meanings of some of the more common bone marking terms. Before we get started, look up the definitions of these common bone marking terms: Canal: Condyle: Facet: Fissure: Foramen: (see Module 10.18 Foramina of Skull) Fossa: Margin: Process: Throughout this exercise, you will notice bold terms. This is meant to focus your attention on these important words. Make sure you pay attention to any bold words and know how to explain their definitions and/or where they are located. Use the following modules to guide your exploration of the axial skeleton. As you explore these bones in Visible Body’s app, also locate the bones and bone markings on any available charts, models, or specimens. You may also find it helpful to palpate bones on yourself or make drawings of the bones with the bone markings labeled.
