Total nasal septal reconstruction using costal cartilage in difficult cases of secondary septoplasty

Abstract

Rhinoplasty and septal reconstruction often require the use of cartilage grafts. Complete nasal septal reconstruction may be required in very specific situations like difficult secondary septoplasty or severely deformed post traumatic noses. Usually in these cases the septal cartilage or bone is insufficient for septal reconstruction. The authors hereby describe a new technique of complete septal reconstruction by using the 7th rib (costal) cartilage combined with author's ingenious technique to prevent warping.

The advanced concepts for septal l-strut re-designing in septorhinoplasty for better strength and stability by considering of center of gravity

“… The comparison of total displacement between standard and new techniques, under loading force of 20 g (a) standard technique of 10 x 10 mm (b) design A: septal support graft (invented technique in this study) (c) design B: straight C-shaped [ 17 ] (d) design C: slope C-shaped [ 17 ]. …”

“…The study explored alternative designs based on a previously developed technique in a clinical study. These designs, referred to as C-shaped septal struts (design B and C, Fig 14(C) and 14(D)) , incorporate two vertical limbs on both ends, which have been previously proposed in clinical studies without computational evidence [ 17 ]. The computational analysis showed that the C-shaped septal struts and septal support graft had better strength than the standard method.…”

“…This study focuses on investigating the effects of various septal L-strut geometries, including the dimensions of the caudal and dorsal portions, the interior corner shape, and the cutting angle. Previous techniques, such as the C-shaped septal strut, have been proposed to enhance its structural strength [ 17 ]. In this work, these techniques are computationally studied and compared to the standard approach, evaluating their structural performance.…”
