Refractory Epistaxis: A Map is Enough!

Combined the big data from Chinese researches and our clinical experiences, we drew a concise "distributed map" of intractable epistaxis showing the concealed bleeding regions and offending vessels clearly (Figure 1). The bleeding site was located accurately according to the "distributed map," and bleeding was stopped via bipolar radiofrequency ablation under nasal endoscope without nasal packing, followed by five classic cases (Figure 2). It is our recommended precise mode of diagnosis and treatment of refractory epistaxis.
