Abstract :Purpose: This study assessed the influence of external carotid artery (ECA) versus combined ECA and internal carotid artery (ICA) supply on surgical outcomes of Juvenile nasopharyngeal angiofibroma (JNA). Materials and Methods: This retrospective observational study included patients with juvenile nasopharyngeal angiofibroma who underwent preoperative transarterial embolization followed by endoscopic resection between 2007 and 2025. Patients were stratified by vascular supply (ECA-only vs. ECA+ICA) and Andrews–Fisch stage. Demographic data, intraoperative blood loss, and residual tumor status were retrospectively analyzed. Results: The mean age was 17.7 years (range 9–62). Age and ECA branching patterns did not differ significantly between groups. All stage I–II tumors were supplied exclusively by the ECA, whereas stage III–IV tumors showed both ECA-only and ECA+ICA supply. Mean intraoperative blood loss did not differ significantly between vascular groups but was markedly higher in stage III–IV disease than in compared with stage I–II. Residual tumor occurred only in patients with ECA+ICA supply. Conclusion: ICA contribution is strongly associated with advanced-stage JNA and increased risk of residual tumor, although it does not significantly elevate intraoperative blood loss. These findings highlight tumor stage as the main predictor of bleeding and completeness of resection.
