Abstract
Introduction Tympanoplasty is a reparative surgery that has multiple indications. The aid of a
microscope or an endoscope is necessary to carry out the procedure. The classic method
utilizes the microscope; however, in the recent decades, the endoscope has been popular.
Although many articles try to compare these two techniques, there is still no robust
evidence that confirms the superiority of either technique. In the present work, we
seek to perform a systematic review contribute with this.
Objectives The present systematic review attempted to compare endoscopic and microscopic surgery
techniques and to discover whether there would be superiority in the results of any
of them, based on data currently available in the literature.
Data Synthesis The objectives of the present review were organized according to the PICO planning
and strategy adapted for systematic reviews. The inclusion and exclusion criteria
were established aiming to select only select primary data. The main medical databases
were searched using an optimized search string with appropriate descriptors. The searched
databases were MEDLINE, LILACS, SciELO, and EMBASE. A total of 99 studies were selected
and 38 were fully assessed after the inclusion criteria were applied. All included
articles were reviewed by all authors and their results were discussed and summarized.
Conclusion The endoscopic technique was shown to be a safer technique comparable in effectiveness
to the use of microscopy. In addition, it provides possible advantages such as shortening
the surgical time and better postoperative pain outcomes.
