ROLE OF PREOPERATIVE EMBOLIZATION IN SURGERY FOR NASOPHARYNGEAL ANGIOFIBROMA: A FIVE YEARS EXPERIENCE
Background: Nasopharyngeal angiofibroma is extremely vascular, locally invasive and aggressive tumor. Among all neck and head tumors, NA prevalence is 0.05 percent to 0.5 percent but its most frequent tumor of the nasopharynx and virtually affects the male adolescents only. Nasopharyngeal angiofibroma shows a strong propensity to bleed in the surgical procedure. Currently, preoperative embolization is frequently utilized to reduce such intraoperative blood loss.
Objective: The objective of the study was to assess the role of preoperative embolization in surgery for nasopharyngeal angiofibroma among patients.
Method: It was cross-sectional descriptive study in which 60 patients with nasopharyngeal angiofibroma admitted in ENT Department of Lahore General Hospital Lahore were included. Data was collected through proforma which was entered into computer software SPSS version 22.0.
Results: Among 60 patients, 63.3% were 12-14 years old. All (100.0%) patients had nasal bleeding and nasal obstruction, 10.0% had proptosis and 18.3% patients had broadening of nose. Among patients, 65.0% had 100-200 ml peroperative bleeding and 76.7% had 4-5 days hospital stay.
Conclusion: Study concluded that preoperative embolization reduces the peroperative bleeding and hospital stay among patients.
