OBJECTIVE The identification of critical characteristics which might predict whether childhood stuttering will become chronic. Part of the study investigates the relationship between hearing and central processing of acoustic stimuli, cerebral dominance and the clinical course of the stuttering. METHODS A prospective study of 79 stuttering children aged(More)
The slow components of the potentials evoked acoustically by pure tones (1 kHz, 0 to 90 dB HL) were compared between two groups of subjects. All subjects of one group were 22 years old; the members of the other group had an average age of 63 years. The P2-latencies of the older subjects were significantly shorter for 60, 75 and 90 dB HL than those of the(More)
We report the clinical course of blunt laryngeal trauma in three young patients. All three patients underwent several phoniatric examinations as well as indirect microlaryngoscopy and microstroboscopy. The follow-up period ranged from three to eight months. In the first case, there was isolated haemorrhage of the left vocal fold; in the second, dislocation(More)
There are currently no known acoustic parameters by which stuttering children can be appraised in order to predict the further course of their speech disfluency. The present study investigates the usefulness of a computer-based speech analysis of fluent utterances. Correlations between acoustic variables, severity, and course of stuttering were sought in a(More)
Reported here is the therapeutic efficacy of Tiapride with 10 10- to 17-yr.-old patients afflicted with severe stuttering problems. During the 20-wk. open, controlled study (baseline, low dose of Tiapride, high dose of Tiapride, follow-up observation without medication) the stuttering in various speech situations decreased markedly. No substantial change in(More)
Nasal speech, which is in many cases the first and only sign of many different diseases, is frequently misinterpreted by the otolaryngologist who examines the patient first. This is demonstrated by an analysis of 23 patients having a submucous cleft palate. A simple diagnostic procedure is suggested that enables the clinician to distinguish between(More)
Early acoustically evoked potentials (brain-stem potentials, latency up to 10 ms) were compared in two groups of varying age (25 and 63 years old, respectively). Although no age-dependent change in potential amplitudes was detected, a significantly longer latency period in older subjects was established for potentials III, IV, V, and VII at all levels of(More)
