Abstract
An alternative technique for secondary tracheo-esophageal puncture and voice prosthesis implantation in topical anesthesia on an outpatient basis was developed. With argon laser beam passed through a glass fibre in the instrument channel of a flexible endoscope a secondary puncture of the tracheo-esophageal wall is obtained. A voice prosthesis is fitted subsequently, so that the whole operation is performed in one session in about 30 minutes. We generally administer 7.5 mg Midazolam orally for light sedation; antibiotics are not required. This method expands the possibility of voice prosthesis fitting in patients who are not considered or willing to have general anesthesia for various reasons. In 33 cases we did not see any complication. In two cases the tracheal wall was too tight due to radiation therapy, so that an operation had to be performed later on in general anesthesia. In one case technical problems led to an operation in local anesthesia in two steps. In all cases the patients did not complain of any considerable discomfort.
