Splanchnocranium
splanchnocranium - Consists of part of skull that is derived from branchial arches - The facial bones are the bones of the anterior and lower human skull Bones Ethmoid bone Inferior nasal concha Lacrimal bone Maxilla Nasal bone Palatine bone Vomer Zygomatic bone Mandible Ethmoid bone The ethmoid is a single bone, which makes a significant contribution to the middle third of the face. It is located between the lateral wall of the nose and the medial wall of the orbit and forms parts of the nasal septum, roof and lateral wall of the nose, and a considerable part of the medial wall of the orbital cavity. In addition, the ethmoid makes a small contribution to the floor of the anterior cranial fossa. The ethmoid bone can be divided into four parts, the perpendicular plate, the cribriform plate and two ethmoidal labyrinths. Important landmarks include: • Perpendicular plate • Cribriform plate • Crista galli. • Ala. • Ethmoid labyrinths • Medial (nasal) surface. • Orbital plate. • Superior nasal concha. • Middle nasal concha. • Anterior ethmoidal air cells. • Middle ethmoidal air cells. • Posterior ethmoidal air cells.

Each consists of inferior and superior borders, medial and lateral surfaces, and anterior and posterior ends. The superior border serves to attach the bone to the lateral wall of the nose, articulating with four different bones. -

ABSTRACT: Objective: To evaluate the vomer bone dimenssional outline changes in relation to the midface hypoplasia of a Class III malocclusion by comparing with normal controls using a three dimenssional CBCT images analysis of Mimics 19.0 software. Material and Method: In total of 96 patients images were both Class III malocclusion as study cases and normal occlusion as controls with age between 15 to 30 years old. All patients were classified into three group based on ANB angular value of Steiner’s analysis. The study group were : normal, mild and sever malocclusion type groups. Linear and angular planes were determined by using 13 skeletal points and analysed by using Mimics 19.0 software. All study groups parameters statistically analysed for significant differences and correlation. Results: A high significant differences between the vomer bone anterior variables (P<0.01) followed by vomer posterior variables (P<0.05) in relation to cranial and midfacial measurements with positive correlation. The pattern of vomer bone was shown highly anterior impaction and backward inclination in sever type malocclusion group and male higher than female. -

The transverse diameter, number, shape and position of the greater (GPF) and lesser (LPF) palatine foramina; canine to canine inter-socket distance; distance between greater palatine foramen medial margins; on each side, the distances between greater palatine foramen and base of the pterygoid hamulus, median maxillary suture and posterior border of the hard palate; pal- atal length, breadth and height; maximum width and height of the incisive foramen; and the angle between the median maxillary suture and a line between the orale and greater palatine foramen were determined. Palatine index and palatal height index were also calculated. An oval greater palatine foramen was present in all skulls, while a mainly oval lesser palatine fora- men was present in 95.8% on the right and 97.2% on the left. Single and multiple lesser pala- tine foramina were observed on the right/left sides: single 44.1%/50.7%; double 41.2%/34.8%; triple 10.2%/11.6%. -

Read Full License Page 1/15 Abstract Introduction: Anatomically, the incisive canals start on the nasal fossa oor, close to the septum, and open at the incisive foramen of the maxillary palatine process. The nasopalatine nerve passes through the incisive foramen as well as the septal artery and the sphenopalatine vein. Also, there may be accessory canals. Typically, the incisive foramen has two incisive canals. This work aimed to analyze the morphology and morphometry of the foramen and incisive canals in the macerated cephalic skeletons. Material and methods: For this purpose, we selected 150 samples of adult individuals, with no distinctions of sex and ethnicity. We analyzed the frequency of incisive canals in the foramen was analyzed as well the area, diameter, and communications of incisive canals with the fossa and nasal cavity. Results: The cephalic analysis results showed that most incisive foramina have at least two canals that communicate the nasal cavity with the oral cavity. -

Posteroinferior Septal Defect Due to Vomeral Malformation
European Archives of Oto-Rhino-Laryngology (2019) 276:2229–2235 https://doi.org/10.1007/s00405-019-05443-3 RHINOLOGY Posteroinferior septal defect due to vomeral malformation Yong Won Lee1 · Young Hoon Yoon2 · Kunho Song2 · Yong Min Kim2 Received: 20 March 2019 / Accepted: 19 April 2019 / Published online: 25 April 2019 © Springer-Verlag GmbH Germany, part of Springer Nature 2019 Abstract Purpose Vomeral malformation may lead to a posteroinferior septal defect (PISD). It is usually found incidentally, without any characteristic symptoms. The purpose of this study was to evaluate its clinical implications. Methods In this study, we included 18 patients with PISD after reviewing paranasal sinus computed tomography scans and medical records of 2655 patients. We evaluated the shape of the hard palate and measured the distances between the anterior nasal spine (A), the posterior end of the hard palate (P), the posterior point of the vomer fused with the palate (V), the lowest margin of the vomer at P (H), and the apex of the V-notch (N). Results None of the PISD patients had a normal posterior nasal spine (PNS). Six patients lacked a PNS or had a mild depres- sion (type 1 palate), and 12 had a V-notch (type 2 palate). The mean A–P, P–H, and P–V distances were 44.5 mm, 15.3 mm, and 12.4 mm, respectively. The average P–N distance in patients with type 2 palate was 7.3 mm. There were no statistically signifcant diferences between the types of palates in A–P, P–H, or P–V distances. -
Bone-Axial Skeleton
BIO 176: Human Anatomy Lab Bone Practical: Lecture Bone-Axial Skeleton Speaker: Heidi Peterson What you will see in the following presentation are all of the bones and features and markings you will need to know for your upcoming practical. We are going to start with the skull. On the skull you will see an anterior view, which is like looking at somebody face to face. On the anterior view the use of your regional terms is going to be necessary. You learned them for a reason and they are going to help you with bones. The first bone you are going to see is your forehead, but it is actually called the frontal bone. The next bone you see is the nasal bone. It also forms the bridge of your nose. You might know it as the cheek bone, but anatomically correct it is called the zygomatic. If you feel in between your two nostrils it might seem strange, but you are going to find a bony protuberance that is called the vomer. The vomer is the bone that gives shape to your lip. That little frenulum comes from the vomer. Also in the skull you will find two big jaw bones. The top jaw bone is the Maxillae. And the bottom jaw bone is the Mandible. There will be features on each of these bones but we will talk about those in just a bit. Starting with the markings or features you will see a circle around something above the orbit of your eye. Anything that is above something anatomically is called superior or supra. -
