Four years after a facial injury, a 63-year-old woman complained of frontal sinus pain and recurrent cutaneous fistula. Repeated headaches and swelling of the right frontal region had started 2.5 years after the injury. The cutaneous fistula was resected but recurred. CT examination revealed a fracture of the anterior wall of the right frontal sinus. Surgical exploration showed that inflammatory granulation and rotten bone fragments obstructed the nasofrontal duct. The duct was opened widely and the fistula closed postoperatively.
