Developmental Anatomy of the Airway

Anatomy for Dental Students, Fourth Edition, demonstrates and explains all the anatomy needed for a modern dentistry undergraduate course. This text covers developmental anatomy, the thorax, the central nervous system, and the head and neck with an emphasis on the practical application of anatomical knowledge. This new edition has been extensively revised and updated in line with contemporary teaching and dental practice. Over 300 new full color diagrams map all the anatomical regions that dental students need to know, while the lively and accesible text guides the reader's learning. Throughout Clinical Application Boxes demonstrate how the form and function of anatomy have consequences for clinical practice. Sidelines boxes contain additional descriptions for key anatomical structures. This text is supported by an Online Resource Centre with multiple choice questions, drag and drop figure exercises, and links to key resources to help readers to consolidate and extend their knowledge of anatomy. Anatomy for Dental Students brings together anatomical structure, function, and their relationship to clinical practice, making it ideal for dental students.

Proper Weight

Objective: In ‘Curriculum' 2002 short answer questions are newly introduced. The content of 1st professional written examination was given but the weightage of different subdivision of Anatomy is not mentioned. So, present study was done to see the content validity of different subdivisions of Anatomy in written examinations. Study design: Descriptive type of study Place and period of study: The study was carried out from January 2003 to July 2004 in the Department of Anatomy, Bangabandhu Skeikh Mujib Medical University, Dhaka. Methods: It was based on a quantitative method; the question paper analysis based study. Results: It is evident from the questions paper analysis that different subdivisions of Anatomy are usually not given proper weight in the Anatomy written examinations. There are some subdivisions of Anatomy which are usually covered less than required. These include Genetics, Histology, General Anatomy, General Developmental Anatomy, Clinical Anatomy, etc. Conclusion: for further improvement of assessment system of Anatomy, content validity is needed to be established. Key words: Content validity, Anatomy, undergraduate, written examinations doi: 10.3329/bja.v7i1.3011 Bangladesh Journal of Anatomy January 2009, Vol. 7 No. 1 pp. 14-18

Objective To describe the developmental anatomy of the eustachian tube (ET) and its relationship to surrounding structures on computed tomography. Study Design Case series with chart review. Setting A tertiary care hospital. Methods ET anatomy was assessed with reformatted high-resolution computed tomography scans from 2010 to 2018. Scans (n = 78) were randomly selected from the following age groups: <4, 5 to 7, 8 to 18, and >18 years. The following were measured and compared between groups: ET length, angles, and relationship between its bony cartilaginous junction and the internal carotid artery and between its nasopharyngeal opening and the nasal floor. Results The distance between the bony cartilaginous junction and internal carotid artery decreased with age between the <4-year-olds (2.4 ± 0.6 mm) and the 5- to 7-year-olds (2.0 ± 0.3 mm, P = .001). The ET length increased among the <4-year-olds (32 mm), 5- to 7-year-olds (36 mm), and 8- to 18-year-olds (41 mm, P < .0001). The cartilaginous ET increased among the <4-year-olds (20 mm), 5- to 7-year-olds (25 mm), and 8- to 18-year-olds (28 mm, P < .0001). The ET horizontal angle increased among the <4-year-olds (17°), 5- to 7-year-olds (21°), and 8- to 18-year-olds (23°, P≤ .003), but the ET sagittal angle did not statistically change after 5 years of age. The height difference between the nasopharyngeal opening of the ET and the nasal floor increased among the <4-year-olds (4 mm), 5- to 7-year-olds (7 mm), and 8- to 18-year-olds (11 mm, P < .0001). Conclusion The ET elongates with age, and its angles and relationship to the nasal floor increase. Although some parameters mature faster, more than half of the ET growth occurs by 8 years of age, and adult morphology is achieved by early adolescence.
