Effective treatment can only be implemented if the bleeding site is quickly identified and the underlying disease controlled.Objective: The relationship between the bleeding site and the pathogenic factors of intractable epistaxis was analyzed to further strengthen the prevention and treatment of intractable epistaxis by outpatient doctors, family doctors and otolaryngologists. Through accurate search and minimally invasive hemostasis, it helped optimize the treatment plan for intractable epistaxis.Methods: This study retrospectively analyzed the clinical data of 90 patients with intractable epistaxis who were admitted to hospital from January 2016 to December 2017. Chi-square test was used to analyze the relationship between intractable epistaxis site with underlying disease, gender and age.Results: The distribution of intractable epistaxis was associated with hypertension (χ2=13.76, P=0.017). The incidence of hypertension was the highest in the olfactory sulcus of t
