Repair of Tympanic Membrane Perforation Using Tachosil Under Local Anesthesia

Tympanoplasty is the gold standard treatment for tympanic membrane perforation. It is done under general anesthesia in the following form: Incision in the post auricular area, harvesting of fascia and cartilage from the concha of the pinna . In Trans ear canal approach starting with debridement of the edges of the tympanic membrane perforation and closing the perforation using cartilage and fascia. After being informed about the study and potential risks, all patients giving informed consent will participate in the study. This study will include two groups. The first group will be treated with the conventional way as described above. The interventional group will be treated using Tachosil in the following order: Local anesthesia using Lidocadren (lidocaine and epinephrine) will be injected to the ear canal using dental needle. Debridement of the edges of the tympanic membrane perforation Placing the tachosil under and above the perforation in the correct order. The patient could be discharged home immediately after the procedure if no adverse effects are seen (dizziness, nausea or vomiting). After one month, similar to the conventional treatment method, the patient will be invited to the otology clinic, for hearing test and microscopic examuntaion of the tympanic membrane, to see if the perforation is closed. The study will compare the success rate in the two groups and if it will be similar that will help publish this method and use it in patients who are not suitable to general anesthesia and in hospitals were waiting time table for operation room is very long.
