Morphometric analysis of middle ear ossicles in adult cadavers
Turkey (TurkMSIC) - Mersin University, Mersin
Department of Anatomy, Mersin University Faculty of Medicine, Ciftlikkoy, 33343 Yenisehir/Mersin
Prof. Dr. Alev Bobus
Prof. Dr. Alev Bobus
Type of Research Project
- Basic science
What is the background of the project?
Please, provide the background of the project (Provide information about the project; min. 10 lines, max. 25 lines) Because of 3 ossicles it has (incus, stapez and malleus) and 2 openings which are opening to the inner ear, middle ear has vital importance for function of audition. At the same time some neural structures which are passing through the middle ear cavity (n. facialis, chorda tympani, n. tympanicus) pose a risk for surgical morbidity in this anatomical region interventions. Middle ear is a place which it is need to be a well-known area because of pathological eradications of itself and audition reconstructions. There are many different initiatives in this region and have several endoscopic and microscopic surgical interventions availabilities.
What is the aim of the project?
Examining morphometric analysis and relationships of tympanic membrane, middle ear cavity and ossicles and to investigate the anatomic structures relationships’; to determine the factors that affect the outcomes of surgical operations of the internal ear.
What techniques and methods are used?
This project will be done in 15 adult cadaver, 30 temporal bones which stay in Department of Anatomy, Mersin University School of Medicine. Surgical methods such as tympanoplasty, tympanomastoidectomy, posterior tymanoanatomy described in the literature will be applied to the cadavers and the ossicles will be photographed by endoscopic and microscopic methods. Ossicles will be removed by dissection and morphometric analysis will be done. Middle ear medial side will be displayed. The round and oval window, n. tympanicus will be evaluated and analyzed.
What is the role of the student?
- The student will mainly observe
- 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 needs to investigate the anatomic localization of the parameters which are mentioned in the background [middle ear ossicles (incus, stapez, malleus), n. facialis, chorda tympani, n. tympanicus, tympanic membrane] to understand the morphological analyse and relationships. Also, If the student will review literature about these parameters it will be effective to understand the aim and course of the project. The student will take a part in taking and saving measurements under the supervision of a teacher during the project. After the project process we want a presentation from student about what the student learnt.
Will there be any theoretical teaching provided (preliminary readings, lectures, courses, seminars etc)
Will there be any theoretical teaching provided for the student (preliminary readings, lectures, courses, seminars)? Please describe how much teaching and by whom. A presentation about the ear anatomy will be given once by Prof. Dr. Alev Bobus
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 scientific report
What skills are required of the student? Is there any special knowledge or a certain level of studies needed?
No specific skills are required
Are there any legal limitations in the student’s involvement
