coblation versus bipolar diathermy in management of refractory idiopathic recurrent anterior epistaxis in children.

Conditions: Epistaxis Nosebleed

Summary: the aim of this study is to compare the outcomes of coblation technique versus bipolar technique in management of rae in children regarding the following: 1. efficacy of each method to stop bleeding. 2. technical feasibility. 3. mucosal healing and crust formation. 4. post operative complications like: synechia formation and septal perforation. 5. nostril stenosis/ atresia.

epistaxis commonly referred to as "nosebleed" remains to be one of the most common ent emergencies presenting to the accident and emergency departments (aed) worldwide. idiopathic epistaxis is a common complaint seen in children in rhinology outpatient clinics. in most pediatric cases, idiopathic epistaxis originates from kiesselbach's plexus, which is located in the anteroinferior portion of the nasal septum; thus, this condition is also known as recurrent anterior epistaxis (rae). the ideal treatment for idiopathic rae has yet to be elucidated. in most cases only leaning forwards, pinching of the nose and washing of the face and nose with cold water is all that is needed to stop the epistaxis; in other cases, more aggressive interventions as using nasal packing or chemical cauterization are needed. although silver nitrate cautery is the most common method of chemical cautery for the treatment of rae, it has mainly been used to control bleeding associated with small vessels and ulceration of the nasal mucosa . electrosurgery appears to be more effective than silver nitrate in controlling bleeding telangiectasias. johnson et al. suggested that bipolar electrocautery may be a superior treatment in children with rae at risk of severe bleeding, in whom chemical cautery will likely fail. coblation is a minimally invasive therapeutic technique that can cover a large tissue volume, thus allowing for rapid ablation and a large area of coagulation with minimal side effects. review of the available literatures doesn't compare between these two methods "bipolar versus coblation regarding their efficacy to control rae in children". in this research we will study the outcomes of both techniques.
