ENDOSCOPIC PUSH-THROUGH CARTILAGE MYRINGOPLASTY COMPARED TO MICROSCOPIC UNDERLAYTECHNIQUE IN ANTERIOR TYMPANIC MEMBRANE PERFORATIONS (Suez Canal University)
Egypt (IFMSA-Egypt) - Suez Canal University, Suez Canal
Department of Otorhinolaryngology

Required: English Accepted: Arabic
Type of Research Project
- Clinical Project with Laboratory work
What is the background of the project?
Microscopic myringoplasty is one of the most frequently performed traditional procedures. A prominent anterior canal wall, and anterior quadrant or marginal perforations may limit the exposure or surgical manipulations when an operation microscope is used for visualization of the surgical field. In these cases, in order to overcome the disadvantages of using a microscope, more invasive procedures that enlarge surgical field are needed such as canaloplasty or a postauricular approach. Use of endoscopes provides considerable advantages with a wide exposure. Repair of tympanic membrane's (TM's) anterior quadrant perforations is harder than the repair of the posterior perforations due to graft's viability, protrusion of the anterior canal wall and medialization of the graft. Graft is usually placed medial to the tympanomeatal flap with an underlay technique for the repair of anterior quadrant perforations.
What is the aim of the project?
To compare operative and postoperative results of endoscopic Push-Through cartilage myringoplasty with the microscopic underlay technique in patients with anterior tympanic membrane perforations.
What techniques and methods are used?
Design: randomized controlled interventional study. Patients: patients with anterior tympanic membrane and air-bone gap ≤25 decibel. Methods: patients are randomized into 2 groups: In Group I; patients were treated with endoscopic push-through myringoplasty and tragal cartilage was used as grafting material. In Group II; patients were treated with microscopic underlay technique and temporalis fascia was used as grafting material. Patients are followed up at 1st, 3rd and 6th postoperative months.
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
- The tasks will be done under supervision
- If the project includes “lab work”
- the student will take active part in the practical aspect of the project
- If the project is clinical
- the student will take active part in the clinical examination
- If the project is clinical
- the student will be allowed to work with patients
- The tasks of the student will be performed on his/her own
What are the tasks expected to be accomplished by the student?
Collecting medical history (done under supervision). Performing general and local examination (done under supervision). Performing otoscope examinations and comment on the findings (done under supervision). Collecting blood samples for lab measurements (done under supervision). Study and explain the basics of tympanic membrane perforation and its causes (done alone).
Will there be any theoretical teaching provided (preliminary readings, lectures, courses, seminars etc)
Theoretical teaching about history, examination, clinical skills, interpreting lap results in form of lectures and clinical talks. 2-3 lectures per week conducted by tutors mentioned above.
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?
Know how to take medical history and perform a general examination. Commenting on otoscope findings. Previous experience with: Otorhinolaryngology.
Are there any legal limitations in the student’s involvement
