Frontal sinus irrigation: indications, results, and complications.

Management, diagnosis, and surgical treatment of the frontal sinus pathology remain a challenge for the rhinologist. Since the introduction of endoscopic instrumentation, the frontal recess may be reached easily and a variety of endonasal approaches have been rediscovered. Although the endoscopic technique allows direct visualization and manipulation, some problems remain, from localization of the frontal sinus ostium during the procedure to the management of the postoperative care to prevent stenosis. The frontal irrigation is suggested as a useful adjunct during the endonasal approach to locate the frontal drainage.
