How to Adjust the Thickness of the Spreader Graft in Nasal Valve Collapse

Abstract

Nasal valve collapse is one of the causes of nasal obstruction and must be considered in patients with nasal obstruction. There are several surgical procedures available to treat nasal valve collapse. Spreader grafts can be used in the treatment of nasal valve collapse by widening the internal nasal valve angle and maintaining the widened angle. However, this procedure requires sufficient amount of cartilage harvested from the nasal septum. Especially, in cases of secondary rhinoplasty or some primary nasal surgery with thin septal cartilage, it is difficult to harvest an appropriate amount of cartilage from the septum. Here, we describe an effective technique for using septal cartilage and TnR Nasal Mesh<sup>®</sup> (T&R Biofab Co., Ltd) for spreader grafts with appropriate thickness in nasal valve collapse.
