Table 1 Approaches to nasal dorsum augmentation

From: In vivo evaluation of a regenerative approach to nasal dorsum augmentation with a polycaprolactone-based implant

Approach Details Advantages Disadvantages Refs.
Cartilage graft Usage of different cartilage sources (septal, auricular, costal), handcrafted Autologous material Possible long-term deformation, partial resorption [1, 36]
Turkish delight Use of autologous cartilage and fascia Partially autologous material, easily to produce and to form Partial resorption and deformation, allograft (fascia) [37, 38]
Bone graft Mostly taken from rib (also as costal cartilage with adjacent rib) or calvarial bone Stability, less warping, resembling bone–cartilage parts of the nose Donor site morbidity, partially unnatural biomechanics [39, 40]
Gore-Tex Synthetic, sponge like materials Easy to use, soft, shapeable, tissue ingrowth possible Extrusion, foreign body reaction [41, 42]
Polyethylene Biomaterial with porous structure, e.g., Medpor Low inflammatory reaction, ingrowth of surrounding tissue Extrusion, infection, stiffness [43]
Silicone implant Preformed implant Easy to use, cheap Extrusion, dislocation, unnatural feeling, capsular formation, deformation of the nose [44]
Fillers Hyaluronic acid derivatives, calcium hydroxylapatite gel Easy to use, resorbable (hyaluronic), long-term stable (hydroxylapatite), easy dosing Infection, necrosis, thinning of skin [45, 46]
Fat transplantation Autologous alternative to the use of dermal fillers, exploiting lipofilling technologies Autologous material, easy to dose, soft, repeatable procedure Large volumes need multiple procedures, larger volumes lacking stability and persistence of shape [47]
