Long terms results of Draf type III (modified endoscopic Lothrop) frontal sinus drainage procedure in 122 patients: a single centre experience

Abstract

Draf III Procedure is safe and effective for patients who have failed conventional frontal sinus procedures and a valid alternative to frontal sinus obliteration. Although the revision rate may appear to be quite significant, it can often be performed as an outpatient procedure and needs to be balanced against the reduced morbidity and the ease of follow-up.
