[Postoperative complications after Caldwell-Luc radical surgery and possibilities of surgical therapy].

The causes for and the avoidance of postoperative complaints following operations on the maxillary sinus were discussed. Additional surgery following the Caldwell-Luc operation is meaningful only in connection with the secondary coverage of defects of the facial wall of the maxillary sinus. Dura is used for coverage. Mucosa from the palate, which is positioned with a new balloon tamponade, is used for larger defects.
