Teflon paste injection into the paralytic vocal fold. A simple procedure to improve disturbed cough function.

Teflon paste injection into the paralytic vocal fold is a simple method for the relief of difficulties with insufficient expectoration and for the prevention of aspiration caused by laryngeal paralysis. The laryngeal valve and voice functions in three patients with unilateral laryngeal paralysis were studied before and after teflon paste injection. Aerodynamic registrations comprised subglottal and supraglottal air pressure and oral air flow during cough and phonation. The aerodynamic records, as well as the patients' own reports, all showed improved laryngeal valve function as a result of the treatment and these improvements were not accompanied by any deterioration in respiratory function as revealed by pre- and postoperative spirometry.

[Observations on the accent-method of Smith in the management of speech and voice disturbances. Part I (author's transl)].

One of the best known methods in northern Europe for the treatment of voice disorders is the "accent-method", which was devised by Svend Smith in Denmark. The method is based on the use of the stressed ("accentuated") syllable as a therapeutic tool to develop pronunciation and a natural attractive voice. Present theories of the physics and the physiology of voice function form the basis for the method, in addition to concepts from modern psychology and pedagogics. By using the technique, it is possible to develop a therapeutic field between patient and therapist within which voice and speech behavior can be treated as a whole. The method is described in detail in the present paper. In a forthcoming paper, the method will be discussed from the viewpoints of the physics and physiology of phonation as well as from pedagogical and psychological aspects,

[Observations on the accent-method of Smith in the management of voice and speech disturbances. Part II (author's transl)].

In an earlier paper [HNO 25, 102 (1977)], the accent-method for the treatment of voice disorders has been described in detail. The rhythmical pronunciation of stressed ("accentuated") syllables with a physiologically correct phonatory respiration and a loose articulation form the basis for this method, and allow treatment of voice disorders as well as problems related to abnormal speech behavior. Further discussion is based on present theories of the physics and the physiology of voice function as well as on concepts from modern psychology and pedagogics.

Arylhydrocarbonhydroxylase inducibility and smoking habits in patients with laryngeal carcinomas.

There is considerable evidence that the inducible enzyme aryl hydrocarbon hydroxylase (AHH) plays an important role in the activation of polycyclic aromatic hydrocarbons (PAH) to ultimate carcinogens. In man, a genetic heterogeneity of AHH inducibility has been demonstrated, and correlated to susceptibility to bronchogenic carcinomas following exposure to PAH. We assessed AHH inducibility in a control group of 102 healthy Swedish citizens and in 41 patients with laryngeal carcinomas. Frequencies of the three phenotypes of high, intermediate and low AHH inducibility in our control group; 8.8%, 42.2% and 49%, respectively, did not differ significantly from frequencies found in a white US population. In the laryngeal carcinoma group, there was a statistically highly significant overrepresentation of patients with high AHH inducibility, 36.6%, whereas 43.9% had an intermediate and 19.5% a low level. Most of the patients were heavy smokers. These findings add further support to the concept that susceptibility to PAH-induced carcinomas is associated with high levels of inducible AHH activity.

[The inverse filtering in the investigation of the laryngeal pathology:a quantitative study of the airflow of glottogram of various intensity].

Inverse filtering is a method of investigate the larynx function that reflects the vibratory movement of the vocal folds by approximately reconstruct the glottal excitation wave. Basically the method creates a filter which characteristics revert the influence of the supraglottal tract and the radiation component on the glottal wave. In this report different quantitative parameters of the flow glottogram (FGG) are studied by means of a computer based program named Superscope in two subjects, one without pathology and another affected of a vocal polyp, at different intensities.

[Electroglottography in the research and physiology of larynx].

Electroglottography (EGG) is a noninvasive method of monitoring the movement of the vocal folds by measuring the variation of impedance to a weak alternating current through the tissues of the neck. Basically EGG is an index of the vocal fold contact area. Despite recent controversy EGG continues being an easy to handle method in larynx basic research, with increasing use in clinical diagnosis and rehabilitation of vocal pathology. EGG technique is described and some of its applications in clinical practice and voice research are pointed out.
