[Tracheostoma valve with integrated cough lid for improvement of hands-free speech in laryngectomees - long term results].
Tracheostoma valves for laryngectomized patients were introduced to enable the laryngectomee after successful surgical voice restoration either by a voice prosthesis, a surgical shunt or microvascular laryngoplasty, to speak without using his fingers to close the tracheostoma. The basic principle of these aids is a mobile valve, which closes automatically at a certain air flow, directing the expired air of the lungs into the pharynx. In spite of the clear advantage of enabling a hands-free speech, the long term acceptance rate is still rather low, which is mainly caused by problems of an airtight fixation within or at the tracheostoma. Another important disadvantage of these tracheostoma valves is the necessity of removing the valve during coughing. The new tracheostoma valve "Window" (ADEVA Company, Lübeck, Germany) offers a clear improvement regarding this point. It is constructed with an additional coughing lid, which opens at a certain airflow and closes automatically after the coughing attack. After successful development and clinical testing of the new aid in 1999 and 2000, it was now the question, if the previously low acceptance rate of tracheostoma valves could be improved in the long term use by this new type of valve. ⋯ The "Window" tracheostoma valve with an integrated coughing lid provides further improvement in speech rehabilitation of laryngectomees. The actual rate of acceptance of 62 % for all "Window" patients (1 month daily use for at least 2 hours) is superior to other reports on the use of tracheostoma valves and probably caused by the additional comfort provided by the coughing lid. Another important factor for the long term use of tracheostoma valves is however the safe fixation of the device in or around the tracheostoma. In this point further improvement is necessary, as only the model with the fixation within the trachea (T-type) led to a satisfactory long term airtight fixation.

Comparative Study[Postoperative bleeding after laser surgery in head and neck tumors].
There are different reports in the literature how often postoperative hemorrhage occurs after laser resection of head-and-neck tumours. This retrospective study investigates the frequency of postoperative hemorrhage after laser surgery of head and neck tumours. Time and extent of bleeding have been considered as well as the localization of the primary tumour and possible general risk factors. ⋯ Laser-surgical resection of head and neck carcinomas does not lead to a higher incidence of bleeding complications compared to ordinary surgery.

Comparative Study[Malignomas of the nasal cavity and the paranasal sinuses: clinical characteristics, therapy and prognosis of different tumor types].
Malignomas of the nasal cavity and the paranasal sinuses count for less than 3 % of the ENT-malignancies. ⋯ Malignancies of the nasal cavity and paranasal sinuses are very often diagnosed in advanced T-stages because of unspecific symptoms. The limited prognosis mainly depends on free surgical margins at the first resection and nodal involvement at the first diagnose. For improvement in outcome of nasal and paranasal sinuses malignancies, prospective multi-center trials are necessary.

Case Reports Comparative Study[From the expert's office. Atlanto-axial subluxation with spastic torticollis after adenoid-ectomy resp. tonsillectomy in rose position - malpractice of the surgeon or the anaesthesiologist?].
An arbitration board had to decide whether or not there had been a causal connection between an adenoidectomy or resp. a tonsillectomy and an atlanto-axial dislocation and if so whether this was to be considered a case of malpractice. ⋯ : In both cases evidence for malpractice could not be found, neither concerning the intervention itself nor the handling in the postoperative period. The latency of several days between the operation and the manifestation of the torticollis is regarded as proof that intraoperatively there was no malpractice. In cases where the torticollis is present immediately after the intervention, as has been reported in the literature, a traumatic luxation during the operation or positioning of the patient may be taken into consideration. Because of the extreme rareness of the complication it does not seem compulsory to make it part of the preoperative informed consent.
