Contrary to the advocated linear approximation of the muscles in closure of the soft palate we have developed a different method which finds its anatomical confirmation in a publication by Kriens. Since we normally have intermingling vertical and horizontal muscle fibres within the soft palate it seemed logical to copy nature by the surgical technique. We believe that we are better able to reestablish normal anatomical findings by two opposing Z-plastics compared with the methods previously described. With this procedure we are also able to shift the centre of muscle function further dorsally, thus achieving a lengthening of the palate as well. Since the procedure is quite atraumatic on account of the oblique cuts, we seldom see tissue dehiscenses and have been able to observe a well functioning palate.
Cleft lips, jaws and palates numerically represent the major part of facial clefts. These abnormalities are evolutionary and they are characterized by a continually recurring anatomic pattern. The necessity of reconditioning form and function implies the application of surgical therapy. Regarding the one-sided closure or suturing of cleft lips, priority is nowadays given to the angular-type incisions, whereas the linear-type incision is still reserved for the double-sided cheiloschisis. In the following, there will be indicated the approved techniques and methods of suturing the cleft palate and a new method will be discussed related to the reciprocal Z-type plastic operation. In the case of speech-improving operations, excellent results can be achieved by implanting autologous costal cartilages into the posterior wall of the pharynx. Apart from a brief mutioning of transverse and diagonal facial clefts, the provision of nasal clefts with composite grafts is finally recommented.

"Proplast" is the propriety name for a recently developed artificial substance developed from Teflon. This porous material is said to be firmly incorporated within 6-8 weeks through tissue ingrowth. It is still under clinical assessment. We report our experiences with 30 Proplast implants in the region of the jaws and face.

The majority of malignant tumors of the skin on the head are found in the upper two thirds of the face. The oral surgeon who is active in the plastic surgery field is therefore frequently confronted with surgical problems exceeding the limited area of the jaws. In this respect nose and ear are regions presenting special problems with regard to esthetics and function.
