摘要:

The results of the use of Proplast, a new alloplastic material, in experimental middle ear surgery are described. This material was tested for cavity obliteration, closure of bony defects and as a columella between the tympanic membrane and the medial wall of the middle ear. Proplast was well tolerated in the middle ear cavity even in cases with inflammation of the middle ear. The implants were integrated within the recipient tissue by fibrous ingrowth occurring within one week. Bony ingrowth was observed in those cases where the implant contacted the bony wall within 3 weeks. Proplast which supported the tympanic membrane was infiltrated by fibrous tissues and incorporated in the lamina propria. No significant side effects were observed in a 6‐month follow‐up period although a possible influence on bone remodeling could not be fully exclu

摘要:

Successful parotid surgery depends on the careful identification and dissection of the facial nerve, and to prevent recurrence all tumours should be excised with a wide margin of normal tissue. These two requirements are facilitated by the technique of intravital staining of the parotid gland with 2.5% methylene blue solution.

摘要:

Parallel anatompathological and enzymatic research led to the discovery of the role played by histiocytes, actively engaged in the lytic process and containing numerous lysosomes, and thus to postulate a cellular and enzymatic concept of otospongiosis. The enzymatic experiments were continued by mico‐electrophoresis and allowed the authors to confirm this enzymatic action. In a third step, specific micro‐concentrations of trypsin and alpha‐1 antitrypsin correlated with cochlear progression, and showed an identical sudden reversal of activity. It was deduced that, when the balance of trypsinlantitrypsin is upset, cochlear deterioration can occur. Confirmation of this concept was done by experimental cytologic findings by scanning electron microscopy. Alteration or destruction of hair cells were the proof of the toxicity of the trypsin action on the inner ear, chiefly on the outer hair cells. The upset of the equilibrium of trypsin and antitrypsin in otospongiotic microfoci and resulting spreading of enzymes from the microfoci into different parts of the cochlea, provokes the peculiar response of the otic capsule with various clinical expressions according to the localization of the impairment: a clinical, stapedial one, resulting in conductive hearing loss; a cochlear one, leading to a sensorineural deafness; a vestibular one, provoking dizziness or even vertigo. The relationship of this enzymatic concept with the disease is explained in detail and leads the authors to express genetic prospects and possibilities of treatment by enzymatic inhib

摘要:

This study was designed to analyse recordings of vocal fold vibrations using the laryngograph, a machine which measures the change in electrical impedance acoss the laynx. Recordings were made of each patient reading a standad text. the output was analysed in two ways: by study of waveform, and by production of a frequency distribution curve, this last being perfomed by aPDP 12 computer. Analysis shows an increase in the low fequencies and irregular curve associated with hoarsenses but no pattern specific for different diseases. After operation and speech therapy an objective measure of success of failure is provided. But for practical use other than in research a less time consuming method of analysis is necessary. Production of this is being considered.

摘要:

Two hundred and eighty‐six patients were exposed to puncture and irrigation of 468 maxillary sinsuses after completion of radiological examination. The radiological interpretations were made by the same radiologist and related to the clinical rate of demonstrable antral fluid in fully and not fully developed sinsuses. Radilogically normal sinuses contained fluid in patients over the age of twelve in 15.3% and when under that age in 39%. The radilogical findings should not override one's clinical judgment, and the age of the patient should be considered when conclusions are to be drawn from the radilogical finding

摘要:

results of diagnostic pocedures are pesented on 259 successive patients with bronchial cancer at Päivärinne Chest Hospital during the period 1967‐73. The most common tumours wee epidermoid (56%), ‘small cell’ (20.5%) and adenocarcinoma (9.5%). In 106 patients (41%) chest adiography suggested a tumour, thought bronchoscopy was normal, and in 22 cases (8.5%) the adiograph was normal but bronchoscopy revealed a tumour. In 10 (4%) both the radiological and the bronchoscopic findings were normal. A definite histopathological diagnosis was reached by bronchoscopy in 144 patients (44%),by mediastinscopy in 14 (5%), by fine needle biopsy in 28 (11%) and operatively in 103 (40%). Using all methods of treatment prognosis was significantly better in the group that had been diagnosed by mass miniature radiography, or accidentally (29% alive) as compared with those who had symptoms of the disea

摘要:

A child aged 31/2 died from a cardiac condition after many and prolonged antibiotic courses: bilateral glue ear had been treated for the previous 18 months. Histopathology showed cholesterol granulomata in the masteroid air cells, with evidence of old haemorrhage, and of former inflammation of bone. The exudate was histiocytic with some giant cells. An ‘orange spot’ on the tympanic membrane was hyperaemic middle‐ear mucosa, heavily infiltated by plasma cells, lymphocytes and histocytes. There was no evidence of hypersecretion. Some of the most abnormal areas were around the stapedial niche and the round w
