Background: Following successful voice restoration after laryngectomy either by a voice prosthesis, a surgical shunt or microvascular laryngoplasty, a further goal in rehabilitation is the insertion of a tracheostoma valve, which enables the patient to speak without using his fingers for closure ofthe tracheostoma. One important disadvantage of the tracheostoma valves, which are available today, is the necessity of removal of the valve in case of coughing, because the valve could be thrown from the stoma by the strongair flow during coughing. As many laryngectomees suffer from chronic bronchitis, this coughing problem is one of the reasons why only few patients could be provided with this useful aid. Method: At the department of biomedical engineering of the faculty of medicine at the university of Groningen, the Netherlands, 1994 two prototypes of a tracheostoma Valve with an integrated cough lid were developed. These devices contain two separate valve systems: the normal speaking valve and a special coughing valve, which opens ata certain air flow and closes automatically after the coughing attack. Thus no manipulations are necessary during coughing, the patient can speak undisturbed. The ADEVA company (Lubeck, Germany) undertook the industrial production of this new type of tracheostoma valve creating different modifications of the prototype #2. Patients:ln four series with 6-8 patients per group the modified tracheostoma valves were tested clinically and the occurringfaults or lack of correct function eliminated by small changes in the production. Results: Meanwhile a suitable model for routine use is available, which was tested in 30 patients so far. This suitability was achieved by improvements in the valve mechanism, the valve seal and the adjustment mechanisms for the individual pressure level of the speaking and the coughing valve. Conclusion: The newly developed tracheostoma valve with integrated coughing lid (Window((R)), ADEVA((R))-medical Company, Lubeck, Germany) providesfurther improvement in speech rehabilitation of laryngectomees. The low acceptance of tracheostoma valves, which enable the patient to speak without using his fingers for closure of the tracheostoma, possibly may be raised by this new aid.
