evaluating management and outcomes of juvenile nasopharyngeal angiofibroma using public health information system

Background: we aimed to investigate the length of hospital stay for resection of juvenile nasopharyngeal angiofibroma (jna) as it relates to preoperative embolization status. methods: pediatric males (0-18 years old) with the diagnosis of a benign neoplasm of the nasopharynx who underwent surgical resection between 2004 and 2022 were included in this retrospective cohort study. patients were then separated into two groups based on their preoperative embolization status. length of stay between the two groups and intercenter variation in length stay was investigated. results: 706 patients, with a mean age of 14 years, were analyzed. 114 patients received embolization prior to surgical resection while 592 patients did not receive preoperative embolization. the age of admission, gestational age, and ethnicity were consistent between the two groups. the length of stay for the group that received preoperative embolization was 3 days, while the length of stay for the no embolization group was 2 days. in addition, nine centers were identified as having significantly higher inter-center variation in los. conclusions: embolization prior to removal of jna increases the length of stay, despite having similar rates of transfusion. while the difference in length of stay can likely be explained by the fact that patients get admitted a day prior to surgery for embolization, it is unclear why there is significant inter-center variation.
