An Alternative Method for Midvault Restoration: "T-Splay Graft"
Background:
The internal nasal valve is one of the highly important anatomical points in rhinoplasty procedures. As a key anatomical area, the anatomical and functional integrity of this region must be preserved or reconstructed during rhinoplasty procedures. Several techniques have been defined in the literature for midvault restoration, among which, the most common are spreader grafts and flaps. Both techniques achieve a natural and harmonic contour but may fail to provide the splay effect to the upper lateral cartilages in some cases. A new technique known as the "T-splay graft", to be used as an alternative approach in cases where there is a risk of midvault collapse, and in which the splay effect in the upper lateral cartilage is preferred to be augmented, is explained in the present study.
Methods:
In the present study, a septal tunnel is opened of sufficient size for the cartilage graft planned for placement, at the planned level of the septum, to expand the midvault region and create a splay effect. A bilateral pocket is created in the inferior mucosa of the upper lateral cartilages. The harvested cartilage graft is passed through the septum in the horizontal plane. The cartilage graft is inserted into the bilateral pockets so as way to create convexity to the dorsum.
Results:
As a result of the applied method, it was established that the internal nasal valve angle could be expanded to the desired extent and the dorsal aesthetic lines could be achieved in a normal anatomical structure.
Conclusions:
This technique enables the lateral direction of the tension between the graft and the upper lateral cartilages, and the creation of a splay effect. As such, we believe that this method is a highly effective alternative for use in appropriate cases.
