[Cranioplasty using computer-designed implants (preliminary report)].

The co-operation among plastic surgeons and computer experts is presented demonstrating the reconstruction of a cranial bone defect of a patient. The adequacy of manufactured implant for reconstruction of cranial bone defect on the base of classic methods in only approximate. Computer aided design is needed for creating a more sophisticated implant. Cranial CT is digitised and a 3 dimensional model is created. The precise implant, manufactured by a computer directed milling machine, fits ino the bone defect. During the operation the cranial bone defect is explored, the bone edges are identified. The implant is fixed and the skull skin is closed. The authors demonstrate a successful operation of a cranial bone defect of 9 x 6.7 cm, the complicated shape and bone surface was reconstructed by a computer aided and manufactured implant. The co-operation of plastic surgeon and computer experts are essential during the process of implant design. The computer assisted and manufactured implants are suitable for the most sophisticated functional and aesthetic reconstruction of bone defect with complicated surface and irregular pattern.

[Plastic surgery in the context of surgery for breast cancer. Breast reconstruction using the patient's own tissue].

The breast reconstructions after mastectomies are overviewed. The criteria of a successful operation are discussed. The result of breast reconstruction with latissimus dorsi and rectus abdominis musculocutaneous flaps are presented. The spectrum of 106 breast reconstructions of from 1987 to 1993 is published. The methods of adequate reconstructions mall, middle size and large breasts are discussed. With the reconstruction of large breasts the best results have been achieved by the transfer of rectus abdominis musculocutaneous flap with micro vascular anastomoses. This flap has the best blood supply and this procedure causes the less damage to the donor area. It is stated that the breast reconstructions with living tissues are superior and preferable.

Experimental microvascular sleeve anastomoses.

Microvascular sutures are the most essential parrt of microsurgery. The three basic types of anastomosis, i.e. end to end (ETE), end to side (ETS) and end in end (EIE), differ, beside the flow parameters, also in the succession, number and depth of the sutures as well as in the technique of suturing. In clinical microsurgery ETE and ETS anastomoses are applied. Several authors have attempted to telescope the vascular ends into each other to simplify the technique of anastomosis, to reduce the time of operation as well as to eliminate intraluminar suturing [1, 3, 6, 9].
