[The facial nerve sensitivity test. Significance and limitation].

This Test which is a renewal of the work of Duchenne de Boulogne (1872) gives an evaluation of the prognosis of a Facial palsy 72 hours after its beginning. It is specially interesting in traumatic cases for it gives the ground for urgent operation or reoperation.

[Opaque meato-cisternography in study of atypical or incomplete syndromes of cerebellopontile angle (value for diagnosis and early treatment of neurilemmoma of the 8)].

It is well-known today that there is a cisternal "no man's land" between the petrous bone and the cerebral trunk in which a tumour can develop insidiously. The clinical signs are very variable and often in contradiction with those described for larger tumours. Tomodensimetry is indicated, but it is not conclusive if the mass is limited to the internal auditory canal or if it extends into the angle for less than 15 mm. Opaque meato-cisternography alone, gives the following information: 1. When a pseudo-tumoural syndrome is present, the auditory canal and cisterna are well opacified. 2. If there is a tumour which extends for more than 20 mm into the cisterna, the oil has a rounded, interrupted contour, and other radiological examinations are useful in this case. 3. When the tumour extends for less than 20 mm into the angle a rounded continuous contour is seen, and Hirtz's axial incidence can be used to measure the tumour diameter. 4. Finally, when temporary opacification faults have been eliminated (after retilting), opaque meato-cisternography is the only examination able to demonstrate the early stages of a tumour, in the intra-canal stage. This early diagnostic procedure has enabled one of us to excise tumours of moderate of even very small volume, under the best surgical conditions, and with functional and vital results which we would not have obtained at a later date.

[Vestibular toxicity of gentamycin: value of the galvanic test (author's transl)].

A total of 6 cases of bilateral vestibular areflexia due to Gentamycin are reported. Vestibular destruction was associated with deafness in only 3 of the patients. Two patients had no signs of renal insufficiency. Galvanic vestibular exploration showed complete and bilateral lack of excitability in 3 out of 4 cases, which could be due to the co-existence of nerve or nuclei lesions. In one case, galvanic excitability was within normal limits, and severe equilibrium problems presisted. The presence of an asymmetry on galvanic examination could be an unfavourable prognostic sign in vestibular toxicity due to Gentamycin.

[Bilateral deafness due to the local use of framycetin (author's transl)].

A case is reported of total bilateral cochleo-vestibular destruction following instillation of Framycetin into the middle ear, under pressure, through a transtympanic drain. Toxicity of Framycetin after local use is exceptional and only one case, reported by Ransome, was found in the published literature. The interest of this observation is that, by using puncture of the foot of the stapes, it was possible to find Framycetin in the perilymphatic liquid three weeks after the injection of the product.

[Surgery of the facial nerve (author's transl)].

The indication of facial nerve surgery are wider than currently believed. The incision of the fibrous sheath, the suture termino-terminal, the nervous graft even very long, the hypoglosso anastomosis give all better results than all other surgical technics. The potentiality of nervous regeneration exist in old people and after very long delay.

[A case of cryptogenetic Frey's syndrome (author's transl)].

A case is reported of gustatory sudation of the cheek without previous parotid lesions. The results of pharmacological tests confirmed the neurogenic origin, blocked by atropine and stimulated by A.C. The published literature is reviewed and a tentative explanation suggested, based on the physiopathological mechanisms involved in Freis syndrome, that the lesion was of neuritic type but had not been recognized.
