Coblation Versus Bipolar Diathermy in Management of Refractory Idiopathic Recurrent Anterior Epistaxis in Children.

"The bipolar technique for group A:~A bipolar with straight blade will be used with a footplate-operated switch to control the coagulation time, and the length, width and depth of penetration of the thermal power.~The lesion will be coagulated in a distal-to-proximal direction to achieve a uniform gray-white coagulation zone in the lesion and surrounding tissue. Multiple ablations at the same area should be avoided to avoid septal perforation. After finishing coagulation small gauze impregnated with antibiotic ointment will be applied for 2 hours postoperatively."

"The coblation technique for group B:~An coblator with tonsillar blade will be used with a footplate-operated switch to control the coagulation time, and the length, width and depth of penetration of the thermal power.~The lesion will be coagulated in a distal-to-proximal direction to achieve a uniform gray-white coagulation zone in the lesion and surrounding tissue. Multiple ablations at the same area should be avoided to avoid septal perforation.
