ObjectiveTo explore clinical features of and treatment method for epistaxis at posterior fornix of inferior meatus.MethodsClinical data of 5 patients suffering from epistaxis at posterior fornix of inferior meatus treated in our department from Jan 2017 to June 2017 were analyzed retrospectively. Frequent arterial epistaxis with hidden bleeding location occurred repeatedly after anterior and posterior nasal packing. All the patients received nasal exploration and electrocoagulation under nasal endoscope.ResultsEndoscopic exploration revealed that the bleeding site was located at the posterior fornix of the inferior meatus in all the 5 patients. Primary hemostasis was successfully achieved by endoscopic electrocoagulation and no recurrence occurred during followup ranged from one month to three months.ConclusionEpistaxis of posterior fornix of inferior meatus should be taken into account when intractable epistaxis occurs frequently and anteriorposterior nasal cavity packing is ineffective. The curative effect of endoscopic unipolar electrocoagulation is definite for hemostasis.
