摘要:

Biopsy specimens from the inferior turbimate of 13 permanently tracheostomized patients were examined by the electron microscope. Variations from the normal were recorded, as proliferation of capillaries, venous congestion and arteriolar contraction. The relation of shunting air away to these changes is discussed.

摘要:

The value of the radiological diagnosis in establishing the localization of a facial palsy resulting from temporal bone fractures has been investigated in 49 cases. Radiological confirmation was found in 21 out of 37 cases of longitudinal fracture and in 11 out of 12 patients (90 %) with a transverse fracture. The fracture line was seen by polytomog-raphy alone in 1 out of 21 (5 %) longitudinal fractures and in 5 out of 11 (45 %) transverse fractures. A precise radiological localization of the facial nerve lesion was only possible if the fracture line was running across the long axis of the pyramid. The surgical revision of 37 patients has shown that the labyrinthine segment of the facial nerve was injured in 93 % of the longitudinal fractures and in 70 % of the transverse fractures. Therefore, one should always be prepared to expose the labyrinthine segment of the facial nerve when revising a facial nerve palsy due to a fracture of the temporal bone.

摘要:

The electroneuronographic registration of the summating potentials of the face muscles has been used to assess the prognosis in 72 traumatic facial nerve lesions. The following guide-lines have evolved from the experience gained: (1) a conservative attitude is indicated if the degeneration of the motor fibres is less than 90 % 6 days following onset of the palsy and (2) a surgical revision of the facial nerve is indicated if the degeneration of the motor fibres reaches more than 90 % during the first 6 days following onset of the palsy. The clinical differentiation in early and delayed traumatic facial palsy cannot be used as a prognostic sign. The amount and rapidity of degeneration of the motor fibres has more prognostic value than the latency between trauma and onset of the palsy. The importance of electroneuronography for the prognosis of iatrogenic facial nerve lesions as well as the value of a careful follow-up of regeneration in facial nerve lesions with preserved continuity of the nerve are discussed.

摘要:

A case of cervical osteophytes producing the sensation of a ‘lump in the throat’ is described. This symptom was relieved by excision of the offending osteophytes. Emphasis is placed on the need for surgical correction before progression of degenerative disease makes the procedure technically impossible. Several points concerning the operative and postoperative management are m

摘要:

The recording of intra-aural muscle reflexes elicited by acoustic stimulation is a routine method in clinical audiology. The most important quantitative examinations of the reflex dynamic, i.e. Metz recruitment and reflex decay in low frequencies, allow the judgement of function of the afferent pathway in the stimulated inner ear and acoustic nerve. Quantitative determinations of the efferent branch were carried out by several authors in a few normal subjects and in several patients with multiple sclerosis or facial palsy. Absolute acoustic impedance – a method yielding wide scattering – was used in order to determine changes in reflex activity in pathological conditions. In the first part of our investigations we tried to find a parameter of reflex dynamic allowing to characterize the functional capacity in the efferent part of the reflex arch in the facial nerve. We examined particularly the steepness of the onset of recorded reflex. Statistical analysis showed an extraordinary stability of this parameter in normal and pathological conditions. Measurements in normal subjects yielded very small intra- and inter-individual variability. In the second part of our experiments we studied normal-hearing patients with unilateral Bells palsy. In the early phase of the lesion we found a significant decrease of the onset steepness in the reflex diagram recorded on the paralyzed side. The greatest reduction of this parameter was seen with a 1,000-Hz stimulus. The time course of the alteration of the onset steepness also seems to have a characteristic pattern. In a further investigation we compared the variations of this reflex parameter with findings in simultaneously recorded electroneuronogr

摘要:

Application of 5-fluorouracil (5FU) for 3 weeks considerably decreased sub maxillary gland weight but had no apparent influence on amylase and protein concentrations in gland extracts and isoamylase distribution patterns as revealed by electrophoresis. After another 3 weeks during which no 5FU was administered, an overproduction of protein synthesis (especially amylase) was observed.

摘要:

Large amounts of the tissue glue Histoacryl applied over the circumference of the epi- and perineurium of the facial nerve produced a rapid decrease of the summation potentials of the face in acute and chronic experiments performed in cats and guinea pigs. No toxic action on the motor neurons of the facial nerve was seen after application of 1 or 2 drops of the tissue glue over the epi- or perineurium of the facial nerve in association with or without a collagen tube splint.

摘要:

Cochleo-vestibular lesions may result from decompression accidents and barotrauma. The etiology of both clinical syndromes as well as their therapy is discussed on the basis of seven personal observations.

摘要:

The present investigations demonstrate in animals (rabbits) the existence of a habituation to the vestibular pendular stimulation comparable to the rotatory habituation by constant angular acceleration. There is no mutual transfer, however, between the two habituations. This confirms that the two modes of stimulation are not equivalent. All the tests have been made by ENG recording in total darkness.
