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.
