Telescopic endolaryngeal surgery.

Magnification for endolaryngeal visualization, biopsy, and removal of benign lesions and carcinoma in situ is achieved using a telescope inserted in stripping type forceps. The combined telescope and forceps are passed easily through any standard laryngoscope with a holder. Excellent visualization is achieved through the telescope, which can be provided with 0 degree, 30 degree, or 70 degree optics. In most circumstances, these instruments obviate the use of the operating microscope, being simpler and just as exact. The field of vision, however, is smaller. The instruments are also ideal for cervical tracheoscopy and mediastinoscopy.
