摘要:
Repetitive screening tympanometry performed in 240 healthy 2-year-old children showed that tympanometric conditions are significantly better in the summer season than in the spring or winter. A very large tendency to spontaneous normalization of the tympanogram type B was demonstrated. Only 16% of the ears that had type B at the first investigation in November had the same type in August. Simultaneous with the normalization of some ears others deteriorated, thus in November type B tympanogram was found in 12%, in February 14.6%, in May 11.3%, and in August 7.2% of all ears investigated. Due to the large variability in the tympanometric conditions which are predominantly caused by catarrhalia, 28.6% of the ears have had type B tympanogram at least once during the period from November to August, while only 1.6% have had type B at all four investigations. The large spontaneous recovery of secretory otitis, demonstrated in the present study, indicates that the child should be observed for a period before implementation of surgical treatment.

摘要:
The operative findings in a homogeneous, preoperatively followed population of 46 3- to 4-year-old children with middle ear effusion treated by adenotomy and paracentesis were correlated with the results of pre- and postoperative tympanometry. Factors of prognostic value were only the immediate type of tympanogram and the quantity of the middle ear effusion, not its viscosity. The combination of the determinative factors divided the material into four groups showing a different course through a 6-month postoperative follow-up. A flat tympanogram and impacted fluid spelt the poorest prognosis, with about 60% recurrences. The influence of the results upon a differentiated treatment of secretory otitis media in the younger age groups is outlined.

摘要:
37 patients with advanced Menière’s disease were operated on by translabyrinthine 8th nerve neurectomy or middle fossa vestibular neurectomy. Cochlear and vestibular nerves, epithelia of the utricular macula and ampullar crista of horizontal canal were studied. All specimens were fairly well preserved and the microscopic studies suggested that there is no general deterioration of these structures even in long-standing, advanced Menière’s disease, but some minor deviations from normal are present in individual

摘要:
27 patients with acoustic neuroma were operated on by translabyrinthine tumor removal. At operation 8th nerve compartments were identified and removed for study. Results of the audiological test battery and vestibular tests were compared with the histological state of the nerve specimens studied. The tumor appears only seldom to invade the cochlear nerve in cases with ‘cochlear’ hearing loss, but in the majority of cases with ‘retrocochlear’ hearing loss the cochlear nerve is

摘要:
A case of olfactory neuroblastoma occurring in a 3-year-old girl is reported. The rarity of the lesion in early childhood is stressed and discussed with the clinicopathological characteristics of the tumour, which are apparently more aggressive the younger the patient. Olfactory neuroblastoma should be considered as a possible diagnosis regardless of the age of the patient.

摘要:
Nasal biopsies from 2 scleroma patients who had received previous X-ray therapy were investigated under the electron microscope. In the lamina propria, the majority of Mikulicz cells contained numerous small vacuoles. This was attributed to the effect of X-ray therapy causing temporary suppression of the inflammatory process followed by new granuloma formation. The vacuoles of the Mikulicz cells contained some fine granular and fibrillar material of unknown origin. Rounded electron-dense bodies with microprojections on their surface were present near some Mikulicz cells. These structures were considered to be Russell bodies. Occasional small lymph vessels with obstructed lumina were seen. This might indicate the rare spread of Klebsiella rhinoscleromatis bacilli to regional lymph nodes.
