摘要:

This study was carried out on 100 tomograms of the petrous bone using Guillen's transorbital view of the anatomy of the middle ear. It provides basic data concerning the morphology, size and surface area of the tympanum, the epitympanum and the hypotympanum. It correlates the surface area of the epi‐ and hypotympanum, and suggests certain embryological interpretation. This study contributes to the diagnostic radiology of the middle ear in the following ways: 1 It provides basic data for the interpretation of tomograms in patients with ossicular dislocation. 2 It provides essential data for the radiology of congenital malformation and of tumours. 3 It puts in perspective certain criteria used for the diagnosis of cholesteatoma. Finally, this study justifies the use of preoperative radiological investigatio

摘要:

Forty‐six children were independently assessed with respect to size of adenoids and other clinical features by 3 observers of differing experience. Similar assessment was made of adenoid area and post‐nasal‐space airway from lateral cephalometric X‐rays. The inter‐observer agreement for these findings has been calculated. Absolute agreement between observers for the assessments is poor and in some instances this is related to clinical experience. In relative terms the agreement is more satisfactory. A nasal obstruction score due to adenoid enlargement has been derived from assessment of mouth breathing and speech hyponasality and this is shown to correlate with the nasopharyngeal radiology score derived from visual assessment of the radiological adenoid area and post‐nasal‐space airway. The radiology score correlates well with measurements of the nasopharyngeal area made by planimetry. Both the radiology score and the nasal obstruction score correlate with the volume of adenoid tissue removed at adenoidectomy. This study provides the basis for a scoring system for the clinical and radiological assessment of adenoids in order to detect preoperatively those children most likely to benefit from

摘要:

Forty‐eight cases of anterior annular cholesteatoma were treated surgically. All these cholesteatomas had occurred following surgical repair of the tympanic membrane by the onlay method. To confirm the likely aetiological causes, 49 specimens of the anterior annular sulcus were studied histologically. It was found that in 31% of specimens there was a fold of epithelium penetrating deep into the subepithelial tissue. In 6 specimens there were epithelial cones present and in 9 specimens excessive subepithelial fibrous tissue was noted. The complication of ‘blunting’ caused by the onlay technique is almost impossible to avoid. A more dangerous complication is annular cholesteatoma. The surgery of blunting and annular cholesteatoma and the principles of the underlay method of grafting are desc

摘要:

In a 12‐month period, brush biopsy through a fibreoptic bronchoscope was performed on 125 consecutive patients who were clinically or radiographically suspected of lung cancer. Of the patients, 62 appeared to have lung cancer. Cytological analysis of the brush‐biopsy specimens was positive in 69%. A total of 58% had positive biopsy, and 58% had cancer cells in the bronchial secretion aspirated during the bronchoscopy. Thirty‐five per cent had positive mediastinoscopy. When the methods of examination were combined, the diagnosis could be established in 90% of the patients. The study shows that brush biopsy and cytological analysis, in combination with the other methods of examination, increase the diagnostic sensitivity in bronchoscopically visible tumours. In bronchoscopically invisible tumours, brush cytological analysis, together with the study of bronchial secretion and fine‐needle puncture, is the most effective diagnostic method. The diagnostic possibilities can presumably bronc

摘要:

The conventional methods of examination do not furnish a complete picture of deep extension of carcinoma of the larynx and piriform sinus. Often the only sign of deep invasion is vocal cord fixation. The purpose of this study was to ascertain whether further information in this respect might be provided by computed tomography. The results of examinations by this technique were assessed on the basis of the findings in whole‐organ serial sections in the transverse plane in 8 patients with laryngeal and 2 with piriform sinus carcinoma. In 2 further patients not undergoing operation, the findings yielded by CT were compared to the laryngoscopic assessment and the findings at a clinical follow‐up after a full course of radiotherapy. CT adds valuable information on the deep invasion of the tumour, especially spread lateral to the arytenoid cartilage, to the laryngeal framework and outside the lar

摘要:

A sample of 50 diabetics was compared with a control group matched for age and sex. Twenty‐two of the diabetics were insulin‐dependent. Subjects and controls were examined otologically and then tested audiometrically using pure tone audiometry, speech audiometry and tone decay after the method of Owens. No significant difference was found between the two groups on pure tone audiometry and speech testing showed all diabetics and controls to be normal. A statistically significant incidence of type‐2 tone decay was found in the overall group of diabetics at 2000 Hz. This may reflect early presby
