[Endoscopic needle biopsy in larynx and pharynx. A simple method for the histological diagnosis of tumours (author's transl)].

The needle-biopsy taken in the pharynx and larynx is a simple and reliable procedure for the histological diagnosis of submucosal tumours. It can be performed either in local anaesthesia using the zoom-endoscope by v. Stuckrad or during microlaryngoscopy under general anesthesia. This method however does neither replace the single biopsy of exophytic tumours nor the microlaryngoscopic excision of suspicious, precancerous lesions.
