Text в Plastic Surgery

More severe maxillo-facial injuries often cause loss of tissues with the (there may be) impairment of function and loss of appearance.

Soft Tissue Plastic surgery has now reached such a state of technical perfection that it is almost always possible to restore completely soft - tissue loss preferable to restoration by a prosthesis.

If surgical repair of the soft tissue of the face is impossible or impractical, an external prosthesis should be made. This form of restoration is often used for the restoration of the ear or the soft tissues around the eye.

The shape of the soft tissue depends to a large extent upon the underlying bony framework. This framework should be restored by surgical or prosthetic means in order to hold the soft tissue in normal position.

Bony Tissue. The loss of bony tissue does not necessarily cause loss of function. But if it does so, the patient has the impairment of normal mastication,

hearing, appearance, etc. The restoration of bony tissue is more difficult by surgical means for the upper jaw.
