Endoscopic sinus surgery: results at 2-year followup.

Endoscopic sinus surgery is a relatively new technique for the management of sinusitis refractory to noninvasive therapy. Success depends on the use of newly developed instruments, including the endoscopes, that allow one to enlarge the natural drainage ostia of the involved sinuses. Furthermore, its use assumes that the mucosal disease is reversible and that destructive procedures, such as the Caldwell-Luc, are unnecessary. To date there have been no reports in the English literature of patients followed for more than a few months. Herein we report 100 consecutive patients followed for at least 2 years.
