Persistent frontal fistula.

ABSTRACT

The frontal sinus is prone to various complications--usually secondary to blockage of the fronto-nasal duct and stagnation of frontal sinus secretions. These pent-up secretions may result in pressure necrosis of the inferior or posterior sinus wall. Involvement of anterior wall is uncommon. We present a case of an anterior wall frontal sinus fistula and discuss its management.
