Various materials can be used for nasal reconstruction. These may be harvested either from the same patient (autograft), from a donor (homograft) or manufactured from synthetic or semi-synthetic materials (alloplast).
Autograft may be harvested from
Soft tissues such as fascia, dermis, and fat are sometimes used for volume augmentation, to hide minor irregularities or also over other implant materials as an onlay graft.
These are harvested from the same patient.
Alloplasts are now being increasingly used as nasal implants. They are made up of synthetic polymers and include the following:
Silicone implants are made up of silicone rubber and have been in use for many years. However, their use is limited because they do not interact with the host tissue due to their non-porous nature. In Asians, who possibly have thicker skin, they have shown some good results.
e-PTFE is a micro-porous polymer with the pore size of about 22 micrometres. This allows for some host tissue ingrowth, sufficient to stabilise the implant while still allowing for graft removal if required. It is soft and flexible and is thus primarily used for volume enhancement.
PHDPE implants are made up of PHDPE polymer which is easy to sculpt into a desired shape. Moreover, PHDPE polymer contains pores with sizes ranging from 100-250 micrometres which allows for significant host tissue ingrowth. Thus, they are used for both nasal soft tissue augmentation and for structural support. Moreover, they are also used for implants for other areas of the face, and are available in various shapes and sizes.
