[Aggravating test by objective audiometry (author's transl)].

ERA is used in 87 cases of suspect aggravation of hearing loss. The late evoked potentials are important additional audiological facts which increase the security of audiological decisions in valuation of the hearing loss level. If there is no full accord of audiological facts, then should be noted beside permanent stubborn aggravation also possibility of absent central information processing.

[On the recurrence risk with partial larynx resections (author's transl)].

28 cases of recurrences after 127 vertical and horizontal partial larynx resections (22 per cent) were analysed. Unfavourable preconditions for partial resections are the affliction of the ary cartilage and arrest of vocal chord movility. The hemiresections according to Hautant have the heighest recidivation percentage (40 per cent) judging from the observations available. Radical operations after failured partial resections are uncertain as to their prognoses.

[Objective diagnosis of the auriculo-temporal syndrome (author's transl)].

After 263 operations on the parotid fourteen developed the auriculo-temporal syndrome. It occurs more often after extensive procedures with dissection of the facial nerve than after simple extracapsular shelling out. A method of establishing the diagnosis of the syndrome objectively by measuring the electrical resistance is described. The aetiology ist attributed to parasympathetic nerve fibres regenerating in the wrong direction after surgery.

[Repeated recurrences after operations of non-malignant parotid tumours (author's transl)].

Recurrences of 222 operated on parotid tumours (1961--1975) are analysed. Recurrences and repeated recurrences of benigh parotid tumours are based on not corresponded praeoperations (without nerve preparation). The half of cases of first-recurrences (mixed tumours) will become further recurrences. In repeated parotid-recurrences should be done total parotidectomy with careful treatment of facial nerve.

[The clinical use of an early evoked potential in the objective audiometry (author's transl)].

The paper gives a description of the derivation of an early evoked potential with a latent period of 6 to 8 ms in man. This 7-ms-potential is also ascertainable with stimulus intensities near the threshold. Our investigations gave evidence that this is superior to later evoked potentials (ERA) in nonsedated children younger than 10 years. The investigation time is short owing to a rapid succession of stimuli (1000 clicks in 5 ms stimulus interval). It is assumed that the potential can be assigned to colliculus inferior.

[Clinical features of papilliferous cystadenolymphoma of the parotid (Whartin's tumour) (author's transl)].

Out of 222 parotid tumours treated by surgery 22 (10%) proved to be cystadenolymphoma papilliferum. The tumour was found predominantly in men over fifty, tended to grow rapidly often causing pain. Suspicion of papilliferous cystadenolymphoma (a parotid tumour in older men) must be confirmed by early operation. The surgical procedure for cystadenolymphoma is like that for pleomorphic adenoma (exposure of the facial nerve followed by partial parotidectomy). An extracapsular dissection is not recommended.

[The alcohol effect on the latency time of acoustically evoked potentials (author's transl)].

The alcohol effect on the latency time of acoustically evoked potentials (ERA and 7 ms-Potentials) was investigated in 19 normal hearing persons. The latency time for N1 of the slow evoked potentials was significantly longer by alcohol concentrations of more than 1%. By blood levels=1.5% and by low stimulus intensity the results were more distinct. The alcohol effect was not registered by the brainstem potentials.
