The Development of the Human Maxilla, Vomer, and Paraseptal Cartilages
THE DEVELOPMENT OF THE HUMAN MAXILLA, VOMER, AND PARASEPTAL CARTILAGES. By Professor FAWCETT, M.D., University of Bristol. THE usually accepted descriptions of the development of the maxilla of man state that it arises by a number of separate centres-the number varying somewhat with the authority, likewise the situation of these centres. No description of the maxilla can be considered complete unless at the same time notice is taken of the manner of development of the premaxilla, which, of course, forms the anterior segment of the adult bone as usually interpreted. But the consideration of the development of the premaxilla may be left until that of the maxilla has been fully dealt with. Before breaking new ground, it may be well to state what are the usual statements with reference to the ossification of the maxilla. These statements are apparently for the most part based on work done by Callender, Toldt, Rambaud and Renault, and Bland Sutton, so far as concerns human anatomy. More recently Franklin Mall has given his views on the subject in the American Jouarnal of Anatomy, views based on observation of specimens treated by the "clearing" method of Schulze. So far as they go, these statements are in harmony with my own notions, which I have for several years now taught. A very precise account is given in Cunningham's Text-book of Anatomy. The maxilla is there stated to be developed in the connective tissue around the oral cavity of the embryo from centres which are not preceded by cartilage, of uncertain number, as early fusion takes place between them. -

Open Access Original Article DOI: 10.7759/cureus.1727 Anatomical Study of the Zygomaticotemporal Branch Inside the Orbit Joe Iwanaga 1 , Charlotte Wilson 1 , Koichi Watanabe 2 , Rod J. Oskouian 3 , R. Shane Tubbs 4 1. Seattle Science Foundation 2. Department of Anatomy, Kurume University School of Medicine 3. Neurosurgery, Complex Spine, Swedish Neuroscience Institute 4. Neurosurgery, Seattle Science Foundation Corresponding author: Charlotte Wilson, [email protected] Abstract The location of the opening of the zygomaticotemporal branch (ZTb) of the zygomatic nerve inside the orbit (ZTFIN) has significant surgical implications. This study was conducted to locate the ZTFIN and investigate the variations of the ZTb inside the orbit. A total of 20 sides from 10 fresh frozen cadaveric Caucasian heads were used in this study. The vertical distance between the inferior margin of the orbit and ZTFIN (V-ZTFIN), the horizontal distance between the lateral margin of the orbit and ZTFIN (H-ZTFIN), and the diameter of the ZTFIN (D-ZTFIN) were measured. The patterns of the ZTb inside the orbit were classified into five different groups: both ZTb and LN innervating the lacrimal gland independently (Group A), both ZTb and LN innervating the lacrimal gland with a communicating branch (Group B), ZTb joining the LN without a branch to the lacrimal gland (Group C), the ZTb going outside the orbit through ZTFIN without a branch to the lacrimal gland nor LN (Group D), and absence of the ZTb (Group E). The D-ZTFIN V-ZTFIN H-ZTFIN ranged from 0.2 to 1.1 mm, 6.6 to 21.5 mm, 2.0 to 11.3 mm, respectively. -

A literature review was conducted in order to investigate the morphology and effect of hamulus pterygoid fracture in clinical manifestation and its relationships with other orofacial components. A literature search was conducted, using Pubmed and Bireme data bases, and covering the time period 1970 to 2019. The Key words for the research were hamulus pterygoid, pterygoid fracture and hamulus pterygoid fracture, resulting in 440 articles, being 41 initials selected. Among them, just 31 were included in the analysis and 08 of the articles were not available through our library system or were in volumes before our holdings began. The remaining were excluded when they weren’t in English idiom, or when didn’t talk about morphological, functional or damages in the hamulus pterygoid. -

Tikrit University – college of Dentistry Dr.Ban I.S. head & neck Anatomy 2nd y. Infratemporal fossa: This is a space lying beneath the base of the skull between the lateral wall of the pharynx and the ramus of the mandible. It is also referred to as the parapharyngeal or lateral pharyngeal space. Boundaries Its medial boundary is the lateral surface of the lateral pterygoid plate . The lateral wall is the ramus of the mandible and its coronoid process. The anterior wall is the posterior surface of the maxilla, at the upper margin of which is a gap between it and the greater wing of sphenoid—the inferior orbital fissure. The roof of the fossa is formed medially by the infratemporal surface of the greater wing of the sphenoid (perforated by the foramen ovale and foramen spinosum). This infratemporal surface 1 cden.tu.edu.iq Tikrit University – college of Dentistry Dr.Ban I.S. head & neck Anatomy 2nd y. of the sphenoid is bounded laterally by the infratemporal crest, where the bone takes an almost right-angled turn upwards to become part of the side of the skull, deep to the zygomatic arch and part of the temporal fossa. Thus the roof of the infratemporal fossa lateral to the infratemporal crest is not bony, but is the space deep to the zygomatic arch where the temporal and infratemporal fossae communicate. The posterior boundary is the styloid process with the carotid sheath behind it. Contents 2 cden.tu.edu.iq Tikrit University – college of Dentistry Dr.Ban I.S. head & neck Anatomy 2nd y. -

Senthil Kumar1, E. Gnanagurudasan2 1Professor, 2Ph.D Scholar, Department of Anatomy, Sri Ramachandra Medical College and Research Institute, Sri Ramachandra University, Porur, Chennai, Tamil Nadu. Corresponding Author: E. Gnanagurudasan Received: 16/07/2015 Revised: 11/08/2015 Accepted: 12/08/2015 ABSTRACT Introduction: Orbit lodges important structures for vision and allows passage of fine neurovascular structures in it. The knowledge of orbital morphometry helps to protect those structures during various surgical procedures. Aim: To determine the morphometry of bony orbit in dry South Indian skulls related to gender and to compare the results with previous authors. Material and Methods: The material of the present study consists of 100 orbits from 50 skulls (right & left) which are identifiable of their sex. Foetal skulls and skulls with damages in the area of measurement were excluded. All the parameters were examined by a single observer using a vernier calliper, divider and millimetre scale. In each wall of the orbit, a bony landmark is chosen from where the distance of other bony structures is measured. Result: The result of the present study showed significance with respect to gender and side. Conclusion: The data of the present study will be helpful for various surgical approaches around the orbit. Keywords: orbit, South Indian skulls, morphometry. INTRODUCTION pyramidal cavity formed by seven bones The bony orbits are skeletal cavities namely maxilla, palatine, frontal, zygomatic, located on either side of the root of the nose. -

We discuss also anatomical structure of the sphenoid bone implementing clinical application of this bone to diff erent invasive and miniinvasive procedures (i.e. FESS). Key words: sphenoid bone, sphenoid sinus, anatomy, computer tomography, FESS. Introduction Sphenoid sinuses are pneumatic spaces lined with mucosa, located in the body of the sphenoid bone. Th eir morphology is highly variable. Th eir variability concerns: 46 Joanna Jaworek-Troć, Michał Zarzecki, et al. • Size • Shape • Number of septa • Level of pneumatization Th ere is a lack of unequivocal pattern of the sinuses, which could have been supposed as anatomically normal. Sphenoid sinuses neighbor through their walls with important anatomical structures, both nervous and vascular — this neighbourhood and anatomical composition of the sphenoid sinuses are extremely important for the surgery in these regions. -
