Topical 15% Trichloroacetic Acid Versus Silver Nitrate Cauterization in the Management of Idiopathic Childhood Epistaxis: A Prospective Double-Blinded, Randomized Clinical Trial

All procedures were performed as office-based procedures under the influence of local anesthesia.Patients were treated with chemical cauterization. Prior to cauterization, 2 cotton packs soaked in 10% lignocaine spray were introduced into each nostril for 5-10 minutes. Then, a cotton-tipped applicator dipped in chemical cautrizating agents solution was applied to the bleeding point, and the sample was firmly pressed for 1 minute. In the case of bleeding, a second application of chemical cautrizating agents solution was applied to the area, after which a cotton tip applicator was applied to the area for 30 s with cauterization of all the feeding blood vessels around the bleeding point. This was followed by the prescription of an antiseptic soothing cream topically twice daily for 2 weeks.

silver nitrate is chemical cautrizing agent ,in the study ,the investigators use it in treatment of anterior epistaxis in children by dissolving silver nitrate crystals in normal saline solution before using.

trichloroacetic acid is well known peeling agent ,in the study the investigators use it as chemical cautrizing agent to treat anterior epistaxis in children .
