Outcomes of Preoperative Embolization of Juvenile Nasopharyngeal Angiofibroma

Abstract

Background: These are rare fibro-vascular neoplasms, out of all head and neck tumors, JNA contributing
for only less than 0.5%. JNA incidence rate almost 1/150,000 and affects men and adolescents’ males
Objectives: To study outcome and the role of Pre-operative Embolization of surgeries for Juvenile
Nasopharyngeal Angiofibroma.
Methods: A retrospective cross sectional study conducted at Al-Sader Medical City during the period 2010
through 2020 included 15 male patients who were managed for JNA, in whom embolization was performed
preoperatively.
Results: The study included 15 male patients with an average age of 16.4 ± 3.1 (standard deviation) (range:
11-22) years. The duration of the procedure is 126 minutes, on average and ranged 75 to 180 minutes;
Average intra-operative blood loss was 300 (range: 150-750) ml. The postoperative hospitalization period
was 2 days in 14 cases and a recurrence rate of 13.3% was reported.
Conclusions: The use of preoperative embolization in JNA patients has been very beneficial in shortening
surgery time, improve bloodless of the operative site, with a significant reduction in intraoperative blood
loss, reduction in postoperative hospitalization time, and reduction in recurrent rate.
