INTRAOPERATIVE BLOOD LOSS IN JUVENILE NASOPHARYNGEAL ANGIOFIBROMA FOLLOWING PRE-OPERATIVE EMBOLIZATION

ABSTRACT Background: Juvenile nasopharyngeal angiofibroma (JNA) is very rare and benign neoplasm of vascular system. It occurs almost in complete nasopharynx of teenage boys. The place of JNA origin is still debatable. Objective: To study the mean intraoperative blood loss in juvenile nasopharyngeal angiofibromas with pre-operative embolization. Material and methods: This descriptive cases series was conducted at Department of ENT, Lahore General Hospital, Lahore for 6 months. A total of 35 cases were included in this study. Embolization was done 23 hours before surgery and gel foam (spongeston) was used for embolization. The amount of intraoperative blood loss was recorded on proforma. Intraoperative blood loss was recorded as per operational definition. Results: All patients were male, aged between 15 and 25 years with mean age of 18.69±3.46 years. 15 patients (42.8%) were presented as stage I to II and 20 patients (57.2%) were presented as stage III. 17 patients (48.6%) were having size of tumour between 2-4 cm and 18 patients (51.4%) were having tumour size between 5-6 cm. Mean amount of intraoperative blood loss (mL) was 748.56±204.89. Mean size of tumour was 5.03±2.05 cm. Conclusion: In conclusion, mean intraoperative blood loss in juvenile nasopharyngeal angiofibromas with pre-operative embolization was 748.56±204.89 mL.
