Stapedectomy modified by the application of fibrin tissue adhesive.

Certain failures of the stapes operation are caused by loosening of the crimped metal loop on the long process of the incus, atrophy or necrosis of the lenticular process, erosion of the long process with the prosthesis causing injury to the labyrinth, erosion of the incudostapedial joint with upward rotation of the long process, and dislocation of the prosthesis. To reduce the occurrences of these failures following stapes removal, we close the oval window by gluing a fascia graft into place with fibrin tissue adhesive. A ceramic strut with a cup on its upper end that fits the lenticular process is glued between the fascia graft and the lenticular process. This method does not cause bone necrosis or blood circulation disturbances. The hearing results are the same or better than those reported for other stapes procedures.

[Dilatation of the glottis in bilateral vocal cord paralysis. Review of various surgical procedures and a report of personal experience using a functional lateral fixation surgical technic].

For the treatment of bilateral vocal cord paralysis, the author's technique consists of preservation of the posterior crico-arytenoid ligament as a hinge as well as turning and tilting of the arytenoid cartilage laterally. It is held in this position with three permanent retention sutures, two of them armed with heavy knots. These knots will reinforce the lateral rotation of the arytenoid cartilage. These sutures run in the submucosa horizontally along the anterior surface of the arytenoid cartilage and are fixed through burr holes on the posterior margin of the thyroid cartilage. This method developed from the original "King Procedure" leaves the laryngeal mucosa maximally undisturbed so that in 80% of the cases preliminary tracheotomy became unnecessary. During a period of 27 years, 110 patients were operated; 27 of them had a previously created tracheostoma. Out of the remaining 83, 16 had tracheotomy directly before surgery. Of the remaining 67 patients, four required postoperative tracheotomy for a few days only, while 63 did not require this additional treatment. The average hospital stay was 11 days. In the majority of cases the operation could be performed under local anaesthesia which helped to establish proper voice function.

[Some reasons for failure in tympanoplasty (author's transl)].

The reasons for failures in tympanoplasty are classified and discussed as anatomical or pathological ones and those, that rise from method and technique. A main cause insists in the pathopolymorphism of the chronic purulent otitis media and the discrepancy of clinical impression and pathological reality. The author wishes to encourage the surgeons to a more radical technique by these examples and to the use of new methods in the field of reconstructive surgery of the middle ear.
