Introduction:
•In the endoscopic tympanoplasty we found a way to give our patients an effective treatment for chronic perforations, not limited by the size or topography
•Because we work in a public hospital we found difficulties to access an operating room with general anesthesia. That’s the reason why we need to perform local anesthesia surgeries on a regular basis.
•The main purpose of this work is to show our outcomes using this technique.
Methods:
•Retrospective review of medical records
•June 2015 to July 2018
•Primary eligibility criteria:
•Patients with no follow-up were excluded
•Surgical technique: endocanal without tympanomeatal flap
•Graft: tragal cartilage and perichondrium
•Anesthesia: injection of mepivacaine 2% + epinephrine, in the circumference of the osteocartilaginous junction.

Conclusion:
•We found in endoscopic tympanoplasty with local anesthesia an effective treatment for the chronic perforations of the tympanic membrane with acceptable rate of success. Knowing that our access to general anesthesia is limited.
•So endoscopic tympanoplasty has turned out to be helpful especially in developing countries, because of the limited accessibility to general anesthesia.
