[Endonasal antrostomy with endoscopical control for chronic maxillary sinusitis (author's transl)]

Abstract

A transnasal approach to the maxillary sinus as a standard operation in chronic maxillary sinusitis is described. A mucosal flap in the lower nasal meatus is electrically circumcised, and a window of appropriate size is formed by osteotomy. The removal of pedicled polyps and cysts from the cavity is controlled by endoscopy, while most parts of the thickened mucosa remain in place and may recover and also line the uncovered areas. If necessary, an opening in the facial wall of 5 mm diameter is established for endoscopical control or manipulations. The preliminary results of 56 endonasal sinutomies are reported, which are satisfactory. The avoidance of postoperative dysesthesia or neuralgia is a marked advantage of the procedure.
