Application of qualitative and quantitative analysis in skull typisation based on skull asymmetry
Bosnia and Herzegovina (BoHeMSA) - University of Sarajevo, Sarajevo
Department of Anatomy, Medical Faculty University of Sarajevo
Professor Aida Hasanović, MD
Associate Professor Aida Sarač – Hadžihalilović, Senior Assistant Zurifa Ajanović
English, Croatian, Bosnian, Serbian
Type of Research Project
- Basic science
What is the background of the project?
Brain and skull asymmetry has always been the research issue as was their mutual conditioning and possible impact on concrete clinical happening. It is very important to understanding the anatomically – antrophological aspect of skull categorization on the basis of its asymmetry. In this sense it is necessary to present the kyphosis of skull base formation as well as their cause and effect mechanisms. If we take a look at history of research into asymmetry of brain and skulls we can indicate that determining factor for definitive form of skull is triple rotation of temporal bone, which by its growth dictates brahicefalic development of human skulls. Relationship between the skull base and temporal bone was also observed and it led us to conclusion that the whole configuration of the skullbase is closely dependant on changing configuration and position of temporal bone. We also examined differences between the capacities of the right and the left half of the human skull. Distinguishing the positive and negative aspects of osteometric and osteoscopic methods in assessing the type of the skull on the basis of its asymmetry and see their impact on classifying.
What is the aim of the project?
To analys the configuration of cranial fossa (anterior, middle and posterior) and cranial diameters in order to asses skull type.
What techniques and methods are used?
While applying classical anatomy – anthropological skull analyzes based on her asymmetry, methodology has two paths: Qualitative (ostheoscopic – anthroposcopic) analyze presents qualitative subjective morphological characteristic assessment (exp. To notice: occipital symmetry, left or right occipitopetaly, left or right temporoparietopetaly, left or right frontopetaly). As well as displaying of anteroposition petrosus part of temporal bone, regarding the type and configuration of the observed skull base. Spotting the position of the posterior part of lesser wing of sphenoidal bone according to the skull asymmetry. Quantitative (osteometric – anthropometric ) analyse is process of measuring individual oblique diameters of the skull with prior clearly defined procedures (skeleton position or position of the skeleton part, instrument, metric unit, anthropometric points)
What is the role of the student?
- The student will observe the practical experiments but will be highly involved in the analysis of the results
- If the project includes “lab work”
- the student will take active part in the practical aspect of the project
- The tasks will be done under supervision
What are the tasks expected to be accomplished by the student?
The student will work with skulls in anthropological laboratory at Department of anatomy provided by mentor, applaing qualitative (osteoscopic – anthroposcopic) and quantitative (osteometric – anthropometric) analyze in assessment the skull asymmetry; search relevant literature on the topic; analyse the data for statistical assessment and write the paper with help of the mentor. Through this process approximately 110 skulls will be hand measured by student with mentioned methods. All data will be inserted in Excel Office and later analyzed.
Will there be any theoretical teaching provided (preliminary readings, lectures, courses, seminars etc)
The student will have a lectures on topic: Application of medical anthropology in skull typisation based on her asymmetry, provided by a mentor. Student will be tutored in recognizing anthropometric points of the skull, application of the cephalometry at craniometrical measurements of the skull oblique diameters, as well as assessment of the type of the skull due to its configuration of occipital part. This will be introduction during first week of project.
What is expected from the student at the end of the research exchange? What will be the general outcome of the student?
- The student will prepare a poster - The student’s name will be mentioned in a future publication - The student will have the opportunity to present the results together with the supervisor at a conference
What skills are required of the student? Is there any special knowledge or a certain level of studies needed?
Student will acquire knowledge which will introduce them with skull typisation based on her asymmetry; search the literature; data analysis; data presentation; skills in writing the paper
Are there any legal limitations in the student’s involvement
