Cases that do not respond to conservative treatments may be considered for one of many surgical procedures, including turbinate excision, submucosal resection, submucosal cautery, laser treatment, cryosurgery, powered microdebridement, or radiofrequency-based ablation. Clinical studies have shown that bipolar radiofrequency-based plasma (Coblation®) devices are capable of creating focal submucosal lesions with minimal or no damage to structures adjacent to the treated area. At present, however, this technique has not been formally evaluated in children. This study will investigate whether surgical turbinate reduction performed using a Coblation device is associated with reduced nasal obstruction symptoms that has failed to improve with other treatment methodologies.
