    Abstract:
    PURPOSE: To investigate the efficacy and safety of preoperative internal maxillary arterial embolization with gelfoam particles in patients with nasopharyngeal angiofibroma. MATERIALS AND METHODS: We retrospectively reviewed a total of 27 consecutive patients with pathologically confirmed nasopharyngeal angiofibroma from August 2006 to September 2018. Of the 27 enrolled patients, 10 patients received surgical excision alone; 17 patients received preoperative internal maxillary arterial embolization followed by surgical excision. Embolic agents were gelfoam particles. RESULTS: The mean volume of intro-operative blood loss was 385.3 ml in patients with preoperative arterial embolization, which was significantly lower than 1215.0 ml in the patients without preoperative arterial embolization (P < 0.001). The mean surgical time was shorter in patients with preoperative arterial embolization than in the patient without preoperative arterial embolization, but the difference had no statistical significance (205.0 vs 264.5 min, P = 0.064). Neurological complications such as facial palsy or vision loss or hemiplegia were not observed in patients with preoperative arterial embolization. CONCLUSION: Internal maxillary artery embolization with gelfoam particles suffices to provide an effective and safe adjuvant procedure for surgical excision of nasopharyngeal angiofibroma.
