Effective medialization of the middle turbinate is an important aspect of ESS. Several techniques of MT medializtion were described. The basal lamella relaxing incision (BLRI) is a novel technique of middle turbinate medialization that is designed to maximize the distance between the middle turbinate and lateral nasal. BLRI and standard MT medialization show no significant difference regarding postoperative mucosal edema, mucopus, polyps, scaring and ability to visualize the sinus ostium. However, better results are noted with BLRI regarding postoperative crustations and total nasal score.
