Minimally invasive nasal endoscopic plasma repair of intra-orbital and inferior wall fractures – a nearly bloodless procedure Advantages: repair of intra-orbital and inferior wall fractures used to require a facial skin incision around the orbit, but nasal endoscopic fracture repair can avoid a facial incision and postoperative facial scar formation, with the significant advantage of cosmetic minimally invasive surgery. Plasma radiofrequency ablation hemostasis technique can avoid heavy bleeding during open sinus surgery and maintain a good operative field. Case: The patient, a 36-year-old male, suffered a fracture of the left orbital wall and inferior wall due to trauma, causing loss of vision and double vision in the left eye, which was not satisfactorily treated by conservative treatment. The sinus cavity was ablated with plasma radiofrequency and hemostasis, the fracture was explored, repaired with dura and filled with high-tech material to restore the normal position of the orbital wall. Postoperatively, the patient’s visual acuity improved and the double vision disappeared. The clear intraoperative field and near bloodlessness should be attributed to the application of plasma radiofrequency ablation technique. The absence of a surgical incision on the patient’s face was attributed to the minimally invasive nasal endoscopic procedure.
