[Neuralgia of the superior laryngeal nerve caused by phonatory malfunctions].

Clinical observations show a close relationship between neuralgia of the superior laryngeal nerve and disorders of the larynx. Neuralgia, and more minor symptoms are usually caused by hyper- and hypotonic phonatory disorders. An unphysiological compensation for glottic insufficiency causes irritation of the sensory telodendrons of the superior laryngeal nerve. As incomplete adduction of the vocal cords can often be found in patients with an autonomic laryngeal dystonia, a syndrome related to anxiety, these disturbances are often misinterpreted as "globus hystericus". However, this diagnosis does not take into account the cause and should therefore no longer be used.

[Dysphonia in childhood].

Dysphonia can be found more often in childhood than in grown-up people. Disturbances of vocal purity occur at least at certain age levels in 23% of all children. Since dysphonia is the most important laryngeal symptom, it should be clarified exactly despite the difficulties of examination in children, in order to exclude tumours, which in most cases will be papillomas. For this purpose we developed a schema which includes not only subjective but also measuring and objective methods. The examples of congenital-inherited, congenital-acquired, non-congenital-inherited and non-congenital-acquired vocal disturbances show that there is a broad spectrum between the evaluation of the first cry, the right evaluation of numerous symptoms, the right evaluation of mutative dysphonias and the assessment of rhinophonias . In cases where it is not possible to clarify sufficiently well the causes of pathological vocal disorders by means of less complicated methods, it is advisable to employ the explained specific examination methods with objective documentation. The oto-rhino-laryngologist consulted by the parents of a child carries considerable responsibility also for the child's subsequent professional career if he is called upon to treat the patient's childhood dysphonia.

Deterioration in hearing caused by hearing aids in children?

(1) There were 7 children among 55 afflicted with severe hearing impairment or with residual hearing (approximately 13%) who exhibited mostly unilateral progression which was ascertained by accurate pure tone audiometric tests during an observation period of several years. (2) Instrument-caused deterioration, however, could not be confirmed in these children. Except for 1 case, deterioration was rather attributable to intercurrent diseases and hearing-aid-independent progression. However, a higher sensitivity to additional auditory damage appears to exist. (3) According to the results of the present studies, the use to super-power hearing aids is indicated in cases of residual hearing although the hearing aid should not be used during the period of intercurrent diseases. In early childhood, intensive speech hearing training should in any case be limited to about three periods of 20 min each daily. This also applies when speech is not understood because experience demonstrates that the acquisition of speech rhythms is a major aid in the process of learning to speak.

[Automated body plethysmography of respiration and voice efficiency (author's transl)].

Efficiency of voice (EV) is understood as the ratio of gained acoustic power to respiratory power during phonation. A fully automatic computer programmed to calculate the EV and the subglottic pressures via body plethysmography is described. The EV ranges from 0.5 x 10(-5) to 120 x 10(-5). The relationship between EV and sound pressure is demonstrated. The results were reproducable.

Results of clinical olfactometric studies.

A modification of a flow olfactometer with a new application appartus, with which "quasi-free" nasal respiration allows the elimination of adaptation without a special testing room, subsequent results using this device to examine olfactory thresholds before and after septum operations, as well as reference to threshold increases in 57 post-operative cases of cheilognathopalatoschisis are reported. An esthesio-neuroblastoma as well as the deformity syndrome with cheilognathopalatoschisis and encephalodystrophy are used as examples for combined olfactory transmission and perception disorders. Studies of 55 smokers with primary neurosensory disorders demonstrated a threefold increase in the olfactory threshold and an up to 50% decrease "fatique-time". A mean acetone deviation factor of 1.93 was seen in 100 students from 20-27 years of age before and after eating. Correspondingly, after a substantial breakfast and lunch, the olfactory threshold attained its maximum daily value within 90 minutes, much more pronounced than after intake of 80 grams of glucose solution. In contrast to the literature, the olfactory threshold was seen to continuously increase, dependent on age. Studies of the perceptive and recognition threshold on 100 normal individuals and 28 patients with hyposmia exhibited with 3 sigma, a significant difference. In patients with hyposmia, the absolute values for the two threshold types vary greatly, however not their deviation factors. More importance should be attached to the sense of smell as the so-called lesser senses give us the greatest pleasures.
