RESUMO
The comparative study was carried out on different CAD/СÐÐ-systems of precision of reproduction of components surface, precision scanning cavities and abatments. Measured value of the regional gap of the frames was made from these systems.

The techniques of formation of esophageal anastomoses are discussed on the basis of experience with 317 operations. The authors believe the following moments to be most important in the creation of communications with the esophagus: the use of a laser scalpel and monophilic atraumatic suture material, accurate apposition of the identical coats of the anastomosed organs by means of sutures placed at some distance from one another and tied not too tightly, creation of an antireflux mechanism in formation of the anastomosis, adequate drainage of the zone of the anastomosis with compulsory isolation of the wound on the neck from the mediastinum by circular stitching of the graft to the surrounding tissues, provision of adequate blood supply to the esophageal stump, correction of tension exerted on the sutures of the anastomosis by means of adequate intraluminal decompression.

The results of total esophagoplasty in cicatricial stenoses of the esophagus and pharynx are analysed. The technical details of formation of the pharyngeal anastomosis with consideration for the anatomo-physiological peculiarities of the pharynx are explained. The method of pharyngoesophagoplasty in combined cicatricial affections of the esophagus and pharynx is described.
