Nasal Morphology and Its Correlation to Craniofacial Morphology in Lateral Cephalometric Analysis
International Journal of Environmental Research and Public Health Article Nasal Morphology and Its Correlation to Craniofacial Morphology in Lateral Cephalometric Analysis Agnieszka Jankowska 1 , Joanna Janiszewska-Olszowska 2,* and Katarzyna Grocholewicz 2 1 Private Practice “Dental Clinic Jankowscy”, 68-200 Zary,˙ Poland; [email protected] 2 Department of Interdisciplinary Dentistry, Pomeranian Medical University in Szczecin, 70-111 Szczecin, Poland; [email protected] * Correspondence: [email protected]; Tel.: +48-91-466-1690 Abstract: Nose shape, size, and inclination influence facial appearance, but few studies concern the relationship between the nasal profile and craniofacial structures. The objective of this study was to analyze association of nasal cephalometric variables with skeletal structures, age, and sex. Cephalometric and nasal analysis was performed in 386 Polish orthodontic patients (aged 9–25 years). Student t-test and Mann–Whitney test were used to compare quantitative variables and Pearson’s or Spearman’s correlation coefficients—to find correlations. Soft tissue facial convexity angle corre- lates to Holdaway ratio, ANB (A-Nasion-B), and Wits appraisal. Nasal dorsum axis, nose length, nose depth (1) and nose depth (2), nose hump, lower dorsum convexity, and columella convexity increase with age. Nasal base angle, nasolabial angle, nasomental angle, soft tissue facial convex- ity and nasal bone angle decrease with age. Nasal base angle and nasomental angle are smaller in females. Thus, a relationship exists between nasal morphology and sagittal jaw configuration. Nasal parameters significantly change with age. Sexual dimorphism characterizes nasal bone angle Citation: Jankowska, A.; and nasomental angle. Janiszewska-Olszowska, J.; Grocholewicz, K.

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.

Another important function that the bones have is to store materials such as calcium, phosphorus and lipids. Additionally, blood cells are synthesized in the red bone marrow to be released into the bloodstream. Bones serve as levers for the muscular system, working with them to produce movement and maintain posture. The human body contains 2 major kinds of bone tissue: compact and spongy. Compact bone (dense bone) is found on the outer surface of bones and serves as a place to absorb most of the stress on the bones. Spongy bone (cancellous tissue) is found on the inside of the compact bone layer. -

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. -

CT of Perineural Tumor Extension: Pterygopalatine Fossa
731 CT of Perineural Tumor Extension: Pterygopalatine Fossa Hugh D. Curtin1.2 Tumors of the oral cavity and paranasal sinuses can spread along nerves to areas Richard Williams 1 apparently removed from the primary tumor. In tumors of the palate, sinuses, and face, Jonas Johnson3 this "perineural" spread usually involves the maxillary division of the trigeminal nerve. The pterygopalatine fossa is a pathway of the maxillary nerve and becomes a key landmark in the detection of neural metastasis by computed tomogaphy (CT). Oblitera tion of the fat in the fossa suggests pathology. Case material illustrating neural extension is presented and the CT findings are described. Perineural extension is possibly the most insidious form of tumor spread of head and neck malignancy. After invading a nerve, tumor follows the sheath to reach the deeper connections of the nerve, escaping the area of a planned resection. Thus, detection of this form of extension is important in treatment planning and estimation of prognosis. The pterygopalatine fossa (PPF) is a key crossroad in extension along cranial nerve V. The second branch of the trigeminal nerve passes from the gasserian ganglion through the foramen rotundum into the PPF. Here the nerve branches send communications to the palate, sinus, nasal cavity, and face. Tumor can follow any of these routes proximally into the PPF and eventually to the gasserian ganglion in the middle cranial fossa. The PPF contains enough fat to be an ideal subject for computed tomographic (CT) evaluation. Obliteration of this fat is an important indicator of pathology, including perineural tumor spread. Other signs of perineural extension include enlargement of foramina, increased enhancement in the region of Meckel cave (gasserian ganglion), and atrophy of the muscles innervated by the trigeminal nerve. -
Endoscopic Supraorbital Eyebrow Approach for the Surgical Treatment of Extraaxial and Intraaxial Tumors
See the corresponding editorial in this issue (E21). Neurosurg Focus 37 (4):E20, 2014 ©AANS, 2014 Endoscopic supraorbital eyebrow approach for the surgical treatment of extraaxial and intraaxial tumors ROBERTO GAZZERI, M.D.,1,2 YUYA NISHIYAMA, M.D., PH.D.,1,3 And CHARLES TEO, M.D.1 1Centre for Minimally Invasive Neurosurgery, Prince of Wales Private Hospital, Sydney, Australia; 2Department of Neurosurgery, San Giovanni Addolorata Hospital, Rome, Italy; and 3Department of Neurosurgery, Fujita Health University School of Medicine, Toyoake, Japan Object. The supraorbital eyebrow approach is a minimally invasive technique that offers wide access to the anterior skull base region and parasellar area through a subfrontal corridor. The use of neuroendoscopy allows one to extend the approach further to the pituitary fossa, the anterior third ventricle, the interpeduncular cistern, the an- terior and medial temporal lobe, and the middle fossa. The supraorbital approach involves a limited skin incision, with minimal soft-tissue dissection and a small craniotomy, thus carrying relatively low approach-related morbidity. Methods. All consecutive patients who underwent the endoscopic supraorbital eyebrow approach were retro- spectively analyzed for lesion location, pathology, length of stay, complications, and cosmetic results. Results. During a 56-month period, 97 patients (mean age 58.5 years) underwent an endoscopic eyebrow ap- proach to resect extra- and intraaxial brain lesions. The most common pathologies treated were meningiomas (n = 41); craniopharyngiomas (n = 22); dermoid tumors (n = 7); metastases (n = 4); gliomas (n = 3); and other miscel- laneous frontal, parasellar, and midbrain (n = 23) lesions. The median length of postoperative hospital stay was 2.7 days (range 1–8 days).
