Complications in sinus surgery and new classification proposal.

Complication overviews may lead to measures directed toward quality improvement and to better information for patients. When evaluating the rhinological literature from 1979 to 1999, a detailed comparison could not be made because of differences in reporting. With the advent of electronically stored medical data, events can be registered better than before. To be able to compile very diverse data from electronic dossiers into concise overviews for feedback, a simple general scale with broad categories is needed. These feedback overviews enable insight in the complication rates of different kinds of sinus surgery and monitoring of changing trends in sinus surgery. An example of a general classification based on severity is presented for use when electronically storing medical data. This scale varies from adverse events (grade A) to death (grade D). A consensus on categorization of complications is a prerequisite for a valid comparison with other clinics. To instigate a discussion about consensus, this classification is presented as an example. Our proposal is presented together with an overview of sinus surgery complications in recent literature for reference.
