Endoscopic repair of nasal septal perforation.

Surgical closure of nasal septal perforation is one of the most challenging procedures in nasal surgery. During the last decade, many endoscopic repair techniques have been described with a success of post-operative repair between 76.4% and 100%. The advantages of this approach are its minimal invasiveness (with no external scars), optimal exposure of the operative field (with better visibility of structures) and good control of perforation margins. The drawbacks are that it is time-consuming and can be difficult to perform, requiring years of endoscopic experience. In this review, all the relevant literature published in which repair was completely made endoscopically is overviewed, comparing the success rates, diameter of the perforation and materials used for the repair.
