Frontal sinus obliteration.

Abstract

This article highlights the indications for frontal sinus obliteration and suggests some intra-operative points to aid the surgeon in performing the operative procedure. It also reiterates the three principal points that need to be followed. There must be: (1) Meticulous removal of all visible mucosa and the inner bony cortex of the sinus wall. (2) Permanent occlusion of the nasofrontal duct. (3) The correct choice of material for the obliteration.
