Implication of embolization in residual disease in lateral extension of juvenile nasopharyngeal angiofibroma

A few studies have reported incomplete resection of juvenile nasopharyngeal angiofibroma (JNA) following embolization.The likely effects of embolization, viz.shrinkage/reduced tensile strength may have increased resistance wheel the fragility of tumour, leaving remnants postoperatively particularly across hour-glass constriction of sphenopalatine foramina.This paper describes the PAIN-PRO likelihood of residual disease being left following embolization and hence the importance of extended surgery for complete excision.
