Endoscopic low-temperature plasma radiofrequency ablation for laryngeal plexiform neurobromatosis-1 in an infant: Case report and review of the literature.

To evaluate the feasibility and effectiveness of using endoscopic low-temperature plasma radiofrequency ablation (RFA) for treatment of laryngeal plexiform neurofibromatosis-1 (NF-1). An infant diagnosed as laryngeal plexiform NF-1 based on a detailed medical history, as well as physical, laboratory, and pathological examinations, was treated under general anesthesia with low-temperature plasma RFA in combination with a self-retaining laryngoscope and high definition camera system.The laryngeal plexiform NF-1 tumor was successfully excised using endoscopic low-temperature plasma RFA without complications. Following surgery, the infant displayed an uneventful recovery and no disease recurrence during a 2-year follow-up period. low-temperature plasma RFA is a feasible and effective method for treating laryngeal plexiform NF-1, and has advantages of producing minimal bleeding, providing complete removal of the tumor, and causing only slight degrees of trauma and postoperative tissue reaction.
