[The indications for revision radical maxillary sinus surgery (author's transl)]

Surgery of the maxillary sinus is one of the commonest in otorhinolaryngology. The classical Caldwell-Luc procedure however is not infrequently followed by infraorbital or some other facial neuralgia or discomfort. In 1976,246 patients were assessed for revision maxillary sinus surgery, and the symptomatology, clinical, transnasal endoscopic and radiological (polytomography) findings were documented. 59 revision operations were performed and a critical analysis of the preoperative, operative and postoperative findings are presented. Polytomography together with sinus endoscopy is a very valuable assessment of the need for revision surgery. Careful sublabial periosteal wound closure is emphasized, and as an alternative to the Caldwell-Luc procedure the intranasal antrostomy under endoscopic control is recommended.
