Abstract

Objectives: This article reviews the advantages and disadvantages of endoscopic ear surgery (EES).

Method: Pubmed, Google and the Proquest Central Database at Kırıkkale University were queried using the keywords "endoscopic ear surgery", "ear surgery" and "endoscopy" to identify the literature needed for the review.

Results: Endoscopes allow for enhanced surgical visualisation. The distal part of the apparatus is illuminated and contains lenses angled to allow a wider view of the operative area. Transcanal endoscopic techniques have transformed the external ear canal (EAC) into an operative gateway. The benefits EES can offer include wider views, enhanced imaging capabilities and increased magnification, and ways to see otherwise poorly visualisable portions of the middle ear. EES permits surgeons to operate using minimally invasive otological techniques. When compared with microscope-assisted surgery, endoscopic tympanoplasty has been shown to require a shorter operating time in some instances. There are a number of drawbacks to EES, however, which include the fact that it is a single-handed technique, that the light source may produce thermal injury and that visualisation using the endoscope is severely curtailed if bleeding is profuse.

Conclusion: EES is a safe and effective technique. The current literature supports the idea that the results achieved by endoscopic methods are usually comparably beneficial to results obtained using conventional microscopic methods.

Keywords: Benefit; Ear surgery; Endoscopic ear surgery; Endoscopy.
