The author describes his method of surgical corrections of the hare lip nose which is based on publications in the literature. In addition he has developed his own technique of modelling the nasal top through intracartilagenous incisions and a special technique of stair-step-rim-nasal incision in order to prevent a linear contraction of the enlarged nostril.

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.
The world-wide acceptance of rhinoplastic corrections has let to the development of multiple surgical techniques in an attempt to improve the ultimate result. After short mentioning of the preoperative measurements the article contains a description of the current concepts of performing osteotomies, tip corrections and the treatment of saddle nose deformities. Surcical methods dealing with secondary deformities including free grafts are discussed. The second chapter is devoted to cosmetic corrections of the face including lid surgery and the so called face lift operation. The value of such procedures is weighed against dermabrasion and chemical face peel in the attempt to improve the appearance. In the thierd chapter the author mentions the newest development in facial nerve surgery in regard to free muscle transfer and nerve cross over operations.

The problems of reconstruction of the destructed mesial lid angle are discussed. Correct evaluation of the lesion is very important. Depending on whether primary or secondary reconstruction has to be done, different technical approaches are recommended. A personal technique of reconstruction of the lacrimal duct is described. This technique has given very satisfactory results.
In a questionnaire sent to alumnae of Swiss schools for dental assistants the choice of the profession, the schools themselves, working conditions for the pupils and the causes for changing the profession or giving it up were examined. Answers and evaluation occurred still during and under the influence of the economic boom, when assistants were able to find employment easily. Questions of salary therefore stood in the foreground, next were working conditions. It is positive to note that the formation of dental assistants in completely privately organized schools shows good results. The changed circumstances in the economy call for a reevaluation of the concept of schooling.
The enlargements of the inner valve is achieved by dividing the upper lateral cartilages from the septum and the coverage of this defect by a flap from the cranial border of the lower lateral cartilages. The usefullness of the so-called low lateral osteotomy and the implantation of a cartilagegraft into the ala is stressed.

Congenital malformations, trauma, benign or malignant tumors may call for reconstructive surgical procedures to cover the defect. In order to establish a proper diagnosis a careful examination including X-rays and biopsies is mandatory. A close contact with with the radiotherapist is most desirable in order to combine the therapy if necessary. After the excision of scars or growth, we differentiate between three phases of treatment: 1. The immediate reconstruction either by local flaps or by free grafts. 2. The delayed excision of the tumor after the establishment of the proper diagnosis. This waiting period (two to three weeks) is used to preform the missing nasal parts in the vicinity of the lesion either on the cheek or forehead. Rib cartilage with split skin grafts or composite grafts is used for this purpose. After the excision of the tumor the nasal reconstruction is carried out during the same operation. 3. Tumor excision and coverage of the raw surface with split grafts in order to inspect the area for several months for any recurrence and the delayed reconstruction with adjacent or distant flaps. The operative techniques are described.

In order to overcome the short comings of a total parotidectomy in reference to appearance and the possible Frey syndrom, the author proposes the free dermis fat transplant directly after the extirpation of the gland. This diminishes the formation of serous fluid in the operated area. Long term observations showed no signs of the Frey syndrome. Further experimental research and clinincal observations will determine if the free fat transplantation is a workable method to prevent the Frey syndrom.
