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