Case 3.17
Published in Monica Fawzy, Plastic Surgery Vivas for the FRCS(Plast), 2023
What problem would you foresee with costal cartilage, and how would you manage that?It tends to resorb and warp, with a greater risk in those with a particularly tight soft tissue envelope.I will cross that bridge if and when I came to it, and use other donor sites, such as:diced cartilage with fascia if the defect is small, orsplit calvarial, iliac crest, or costal bone for larger defects.The disadvantage of bone is that it provides an unnaturally rigid feel, despite the advantage of a rigid structure.Lastly, I am aware of commercial costal cartilage allografts which would avoid another donor site.
Revision Rhinoplasty

Costal cartilage can be shaped based on its intended use: It can be reduced to diced or ultradiced cartilage to eliminate the risk of re-curvation during the recovery period in cases where the aim is just to provide volume.It can be cut obliquely for structural grafts with the aim of supporting the dorsal roof, nasal tip, or side walls which will reduce the risk of curving (Figure 6.28) [5].
The neck, Thoracic Inlet and Outlet, the Axilla and Chest Wall, the Ribs, Sternum and Clavicles.

The Costal Cartilages are normally symmetrical in size and shape at any one level, and commonly lie in a horizontal plane. They are thickened close to the sternum, and taper towards the costochondral junctions. For illustrations see Illus. COSTAL CARTILAGES.

The ribs are another championed donor site for cartilaginous material during rhinoplasty. The advantage of costal cartilage harvest is that it provides a significantly greater amount of material that may be necessary during the correction of extensive defects. A two-team approach allows for simultaneous execution given the anatomic proximity between donor and recipient sites. However, it also carries a higher risk of donor site morbidity with the potential for an external scar, chest wall deformity, and iatrogenic pneumothorax [12,18]. Costal cartilage is also reported to have higher rates of warping and eventual distortion [9,19]. For these reasons, some generally prefer septal and auricular cartilage for most defects, while costal cartilage should be harvested in the case of insufficient autogenous material and/or in the setting of extensive deformity. Regardless, all three forms are generally technically sound in the sublabial approach. This this study, rib was harvested in four cadavers to obtain additional cartilage for grafting purposes.

HP improved only the tenth rib excursion. Upper ribs move forward and upward, and lower ribs move sideways during inspiration (Zhang et al. 2016). These are called pump-handle and bucket-handle motions, respectively. It is probable that upper rib motion is related more to the extensibility of muscles in front of the chest including that of pectoralis major (Putt et al. 2008). Costal cartilages of lower ribs, including the tenth rib, are not directly attached to the sternum. In addition, the tips of the eleventh and twelfth ribs are not attached to the ventral bone and are attached only to the thoracic spine. Thus, compared to the axillary and xiphoid excursions, the tenth rib excursion may be related less to the extensibility of front muscles and affected more by back muscles. HP increased ST, 10 mm DT, and 20 mm DT, but HP had smaller thermal effects on 20 mm DT than did CRet. HP might have sufficient thermal effects on the superficial back muscles but not on intercostal muscles. Therefore, HP improved only the tenth rib excursion.

In the Nuss procedure, the concave part of the thorax is forcibly elevated and metal plates are placed underneath the elevated part to maintain its position. The concave part consists of ribs, costal cartilages and the sternum. Among these anatomical structures, only costal cartilages can be bent with force; the bony part of a rib does not change its shape. Hence, the proportion of cartilage in the bone-cartilage complex can influence the outcomes of the Nuss procedure. When the deformed part of the chest consists only of cartilage, the deformity can be optimally corrected with the Nuss procedure (Figure 1(A)). On the other hand, when the deformed part includes bone, complete correction cannot be achieved, since the bone parts (asterisk in Figure 1(B)) remain uncorrected.
