Juvenile nasopharyngeal angiofibromas in Denmark 1981–2003: diagnosis, incidence, and treatment

Abstract

Forty-five male (no female) JNA cases were identified. In 43 cases, clinical data were recovered. Median age was 15 years. The incidence rate in Denmark was 0.4 cases per million inhabitants per year and 3.7 cases per million males (aged 10-24) per year. All patients underwent surgery, and the endoscopic approach was increasingly being used. The embolization procedure proved to be safe and decreased the intraoperative blood loss statistically to 650 ml in the embolized group from an average of 1200 ml in the non-embolized group (p<0.05). Similarly, the need for peroperative blood transfusion was reduced (p<0.005). The primary recurrence rate was 23% and no patients died.
