title: Technique, indication and evidence of sinuscopy.
abstract: It is reported on experiences made with endoscopy of the maxillary sinus by means of three different angular optics according to Hopkins (0 degree, 30 degrees, 70 degrees). A sinuscopy is indicated in order to obtain an early diagnosis of malignant tumour growth; it is decisive as to an operation of the maxillary sinus to be carried out; it clarifies clinically uncertain maxillary sinus findings. In addition to the usual investigation methods, the sinuscopy allows a direct local diagnosis. Moreover, diagnostic and therapeutic operations may be carried out by means of a biopsy forceps.
