Objective measurements derived from digitized laryngeal stroboscopic images were used to demonstrate changes in vocal fold vibration and in the size of benign lesions after 3 months of voice therapy. Forty chronically dysphonic patients were studied. By means of a rigid stroboscope, pretreatment and posttreatment recordings were made of the vocal folds at… (More)
Left vagus nerve stimulation (VNS) by means of an implanted electrode has proven to reduce seizure frequency in epileptic patients with medically refractory seizures. This technique is now widely applied over the world. Voice changes appear to be one of the major side effects. The morphodynamic changes in the larynx and the acoustic impacts have been… (More)
We examined the thyroarytenoid muscles of 23 larynges in order to assess function-related characteristics and to discover age-related changes. The neonatal thyroarytenoid muscle differed from limb muscles in the slow maturation of fibre types. In adults, we examined the medial part of the thyroarytenoid muscle. It showed a larger variation in fibre size and… (More)
OBJECTIVES The reliability of objective measurements on digital laryngeal images was investigated. METHODS The magnitude of the error of measurement of surface areas by visually tracing the outline was determined for three different areas: the area of the lesion and, during vibration, the glottal area on maximal opening of the vocal folds and the glottal… (More)
A survey is given of histological and histochemical aspects of mammalian thyroarytenoid musculature of several animal species. Purpose of the study is to find out in what respect the possibility of differentiated and prolonged sound production can be found back in the histological and histochemical properties of mammalian thyroarytenoid musculature. The… (More)
The scimitar syndrome is a congenital anomaly of the venous system of the right lung. This diagnosis is suspected when a scimitarlike shadow is found on the thoracic roentgenogram; the definitive diagnosis is made by angiography when an abnormal outflow of the venous system of the right lung is found. Dyspnea and recurrent infections are the most prominent… (More)
For the first time the hormonal activity of a glomus jugulare tumour, clinically manifest by intermitting hypertension, could be demonstrated by catecholamine level determination in blood. Endocrinological and diagnostic aspects concerned to the differential diagnosis of the hypertension in these patients are discussed.
