摘要:
On the basis of six particular cases in which the various impairments of the middle ear were verified during the surgical intervention, the authors show how it is possible to obtain by means of the Madsen ZO 70 electroacoustic impedance meter and of the Grason-Stadler Model 1720 otoadmittance meter useful additional information about the preoperative dynamic behavior of the tympano-ossicular system. With regard to the measurement of the ‘susceptance’ and the ‘conductance’ at 220 and 660 Hz, it permits to establish a better differential dia

摘要:
We present an analysis of the otological and audio logical findings in 63 patients (113 ears) in which a myringotomy for suspected serous otitis media has been performed. In 98 ears (87 %) the impedance data correlated with otoscopy. Tympanograms did not give further information than otoscopy alone in 49 patients with reliable pure-tone audiometrical results, whereas tympanograms would have missed 6 out of 78 ears containing fluid and 6 out of 49 ears who improved in hearing following myringotomy and transtympanic tube therapy. We feel, however, that, in patients who are too young or too retarded to be tested audiometrically, tympanometry in combination with otoscopy could eventually be helpful in settling the indication for a myringotomy, since 3 out of 83 ears with middle ear fluid and hearing improvement following transtympanic tube therapy had pathological tympanograms in spite of normal-seeming ear drums.

摘要:
The residue of tectorial membrane insertion of cochlear inner sensory cell hairs was studied under a scanning electron microscope. In addition to the clear imprints resulting from outer sensory cell hair insertions, an adjacent medial row of bow-shaped imprints was noted on the base of the tectorial membrane. The relative position of these imprints corresponded to the location and the size of the inner cell hairs. These imprints were thus thought to arise from the insertion of the inner sensory hair cells. Such imprints were found only in the lower turns of the cat’s cochlea, but not on the guinea pig tectorial membrane. Thus an actual physical contact between the tectorial membrane and the inner sensory cell hairs may exist in some species but not in others, and when there is physical contact, it is thought to be less firm than that of the outer sensory hair cell

摘要:
This paper discusses the functional relationship between the position of the stapedius reflex threshold and the results of the Feldmann test. 25 hearing-impaired patients have been examined in this respect. A positive correlation on a 5 % level of significance has been confirmed between these two parameters.

摘要:
An analysis is presented of a series of 434 operations in chronic otitis media in children taking into account the extent of the lesion, the type of operation, the early and late functional and morphological results. In 18% of cases a radical operation was performed, in 21 % atticotomy or other conservative operations, and in 61 % open or closed tympanopiasty. Because of dynamic character of the cholesteatomatous process in childhood, the creation of a ‘safe ear’, i.e. free of recurrences of cholesteatoma, is difficult by means of closed tympanopiasty operati

摘要:
Nowadays noise in industry cannot be eliminated by technical means alone. Therefore, exposed workers have to wear an ear protector to prevent the occurrence of deafness caused by professional noise. Patients with chronic otitis media and permanent or intermittent otorrhea should avoid the prolonged use of ear protectors. On principle, such patients are not allowed to work in a noisy environment (inaptitude for noisy employment/ change of occupation) unless the contraindication for use of ear protectors can be eliminated by therapeutic means (such as operation).

摘要:
The Haemophilus influenzae meningitis is the most common cause of deafness following meningitis. Five of 22 children (23 %) had this complication in spite of antibiotic treatment (ampicillin). The question must be raised whether a different antibiotic treatment could avoid the inner-ear problems occurring in Haemophilus influenzae meningitis. Early decompression of the internal auditory canal has reversed deafness in one of four children.

摘要:
The present study deals with the behaviour of the erectile tissue of the nasal mucosa in the normal rat and after selective transection of the autonomic nerve supply, measured with physiological and histometrical techniques. In the normal animal cyclic changes in the patency of the nasal lumen occurs with a cyclus time of 61 min, disturbances being observed in this rhythm a few weeks after transection of the various autonomic nerves. Selective transection of the main route of the sympathetic or the parasympathetic systems results in a dominance of the antagonist (congestion or decongestion). Transection of both systems does not result in a significant change in the dilated state of the nasal cavity from normal, although the cyclic activity disappears. A tendency towards a normal nasal cycle was observed several months after transection.

摘要:
During the course of 1974, 16 tympanoplasties were performed on patients who suffered from serious congenital heart defects. 50 % of the cases had recurrence of the perforation. It was not possible to deny the evidence of other failing factors such as the poor hemodynamic condition. Indications for performing a tympanoplasty were motivated by the necessity to eliminate a focus of dangerous infection to the patient before undergoing a major cardiac intervention. These indications have been modified to the following: (a) chronic cholesteatomatous otitis remains a valid surgical indication and (b) simple chronic otitis could be controlled by local medical treatment. The tympanoplasty could be postponed after the cardiac intervention when the hemodynamic condition had been corrected.
