PURPOSE: The structures of the larynx are exposed to view and made accessible without optical distortion using a special endoscopic tube during general ansethesia. The endoscopic tube is secured in a stable fashion to allow bimanual procedures to be performed within the larynx with and without additional optical magnification.

POTENTIAL INDICATIONS:

Precise diagnosis of organic lesions of the larynx, particularly of those parts of the larynx which difficult to examine, and removal of a biopsy specimen for histology.

Drainage of abscesses and cysts, etc.

Complete removal of benign lesions from within the larynx, possibly with the laser.

Removal of local edematous swellings.

Removal of scars, strictures, synechiae, and webs, possibly with the laser.

Procedures to improve function in vocal cord paralysis and vocal cord defects.

POSSIBLE ADVERSE EFFECTS:

Known potential adverse effects include:

  Bleeding

Infection

Hoarseness from scar tissue formation

Injury to teeth

Temporary alternate airway access with tracheotomy

There are risks involved with general anesthesia, but are uncommon. You may discuss these with the anesthesiologist before surgery.
