ABSTRACT When the German DRG system was implemented there was some doubt about whether patients with extensive head and neck surgery would be properly accounted for. Significant efforts have therefore been invested in analysis and case allocation of those in this group. The object of this study was to investigate whether the changes within the German DRG system have led to improved case allocation.
Cost data received from 25 ENT departments on 518 prospective documented cases of extensive head and neck surgery were compared with data from the German institute dealing with remuneration in hospitals (InEK). Statistical measures used by InEK were used to analyse the quality of the overall system and the homogeneity of the individual case groups.
The reduction of variance of inlier costs improved by about 107.3% from the 2004 version to the 2007 version of the German DRG system. The average coefficient of cost homogeneity rose by about 9.7% in the same period. Case mix index and DRG revenues were redistributed from less extensive to the more complex operations. Hospitals with large numbers of extensive operations and university hospitals will gain most benefit from this development.
Appropriate case allocation of extensive operations on the head and neck has been improved by the continued development of the German DRG system culminating in the 2007 version. Further adjustments will be needed in the future.

    ABSTRACT: The existing therapeutical options for the tracheal and pharyngeal reconstruction by use of implant materials are described. Inspite of a multitude of options and the availability of very different materials none of these methods applied for tracheal reconstruction were successfully introduced into the clinical routine. Essential problems are insufficiencies of anastomoses, stenoses, lack of mucociliary clearance and vascularisation. The advances in Tissue Engineering (TE) offer new therapeutical options also in the field of the reconstructive surgery of the trachea. In pharyngeal reconstruction far reaching developments cannot be recognized at the moment which would allow to give a prognosis of their success in clinical application. A new polymeric implant material consisting of multiblock copolymers was applied in our own work which was regarded as a promising material for the reconstruction of the upper aerodigestive tract (ADT) due to its physicochemical characteristics. In order to test this material for applications in the ADT under extreme chemical, enzymatical, bacterial and mechanical conditions we applied it for the reconstruction of a complete defect of the gastric wall in an animal model. In none of the animals tested either gastrointestinal complications or negative systemic events occurred, however, there was a multilayered regeneration of the gastric wall implying a regular structured mucosa. In future the advanced stem cell technology will allow further progress in the reconstruction of different kind of tissues also in the field of head and neck surgery following the principles of Tissue Engineering.
