[The pharynx following tumor-surgery interventions. The variability of the clinical images in conventional fluoroscopic diagnosis].

: The present study gives a survey of radiological findings after surgical treatment of laryngeal and pharyngeal carcinomas, whereby the surgical procedures and the localisation of tumours found special consideration. One important point of view of modern surgery is the improvement of quality of life. By reason of this point the role of reconstructive surgery will become increasingly important. Representative radiographs between 1997 and 1999 are discussed to show the difficulties to distinguish between normal and pathological postoperative findings after operations of hypopharyngeal diverticula, after partial and total laryngectomy as well as after different methods of surgical reconstructions of pharynx. The examinations which are shown were realized with the conventional radioscopy. Hereby the normal radiological findings and their comparison to the particular postoperative specials rank first. Furthermore the early and late postoperative complications are mentioned. A variety of surgical procedures in treatment of laryngeal and pharyngeal carcinoma make new demands on the postoperative diagnostic possibilities especially on the postoperative pharyngography. The variability of the postoperative radiographs complicates the differentiation between normal and pathological radiological findings and only the exact knowledge of the performed surgical procedure allows their differentiation.
