TLDR - apply an electric current to the septum, and the cartilege becomes plastic. Press it with a properly shaped mold, turn off the current, septum retains new shape. Simplicity.

Abstract: An alternative to conventional “cut-and-sew” cartilage
surgery, electromechanical reshaping (EMR) is a molecular-
based modality in which an array of needle electrodes is
inserted into cartilage held under mechanical deformation by
a jig. Brief (ca. 2 min) application of an electrochemical
potential at the water-oxidation limit results in permanent
reshaping of the specimen.
Highly sulfated glycosaminoglycans
within the cartilage matrix provide structural rigidity to
the tissue through extensive ionic-bonding networks; this
matrix is highly permselective for cations. Our studies indicate
that EMR results from electrochemical generation of localized,
low-pH gradients within the tissue: fixed negative charges in
the proteoglycan matrix are protonated, resulting in chemically
induced stress relaxation of the tissue. Re-equilibration to
physiological pH restores the fixed negative charges, and yields
remodeled cartilage that retains a new shape approximated by
the geometry of the reshaping jig.
