Functional endoscopic sinus surgery. Theory and diagnostic evaluation
D. W. Kennedy, S. J. Zinreich, A. E. Rosenbaum and M. E. Johns
The keys to functional endoscopic sinus surgery are an understanding of the
underlying mechanisms of paranasal sinus disease and the ability to
diagnose the causes accurately. Previously unrecognized causes of recurrent
acute sinusitis and of chronic sinus symptomatology can now be identified
by careful diagnostic evaluation. Systematic nasal endoscopy and
high-resolution computed tomographic imaging provide complementary
diagnostic information that can allow for the recognition of problems not
identifiable by other means. The ability to diagnose these problems and to
correct them with functional endoscopic surgery heralds new possibilities
in the field.
