MEDIA-WITH SPECIAL REFERENCE TO CHANGES OF THE LAMINA PROPRIAShuichi Arai1991 Volume 34 Issue 6 Pages 595-623

JOURNAL FREE ACCESSElectron microscopy of tympanic membranes (TM) removed from patients of adhesive otitismedia (AOM) was undertaken in comparison with the fine structure of normal TM obtained in mobid anatomy of patients without any disease of the ear.
Observation was made with a special reference to the structure of the lamina propria and changes of the adhered TM can be classified into three histological types of i) Inflammatory granulation type, ii) Scarring tissue type, and iii) Hyalinization type. It was revealed in tannic acid-uranyl acetate stained sections that a small amount of elastic fibers is present in the lamina propria of the pars tansa of normal TM. In TM of AOM, cellular proliferation and thickening of the epidermal cell layer and a tendency to form rete pegs in the basal cell layer were common. The most remarkable changes in TM of AOM were found in the lamina propria where the normal four layered architecture of the fibrous connective tissue has disappeared almost completely. In the inflammatory granulation type, a marked thickening of TM with proliferation of fibrous granulation tissue and elastic fibres were found together with chronic inflammatory cell infiltration. In the scarring tissue type, marked and irregular proliferation of fibrous connective tissue and elastic fibers were found in thickened TM. While in the hyalinization type, fibrous layer of TM had completely been replaced by a lot of collagenous microfibrils and amorphous substance.
It is no distinct that cases of marked thickening and hyperkeratosis in the epidermal cell layer of TM of AOM will have a possibility of changing to pars tensa cholesteatoma in the future. Causes and pathogenetical relationships among these histologically different types of TM in AOM are unclear, though circulatory disturbance of the tympanic membrane may intimately related to the pathogenesis of the hyalinization type, and various factors such as local physiological conditions of patients and qualitative and quantitative differences and processing speed of inflammatory changes may be considered basically in the cause of both the inflammatory granulation type and scarring tissue typeView full abstractDownload PDF (58160K) -

JOURNAL FREE ACCESSComputed tomography (CT) is an important image processor for analysing temporal bone disease, but huge numbers of these two-dimensional images have required doctors to have a special ability of stereoscopic understanding. To solve this problem, we have tried to reconstruct temporal bone three-dimensionally from CT film using a personal computer and examining the possibilities of its clinical use.
Three cases of temporal bone CT films (otosclerosis, congenital cholesteatoma of pyramid and large mastoid cholesteatoma) were examined. Five structures of temporal bone (temporal bone contour, middle ear, mastoid, inner ear and cholesteatoma), which were chosen from enlarged black and white films originated from CT films, were inputted into the personal computer. The scale of each CT films were used as a standard point, for a decision of each image data X and Y points. Nexo, Z points were decided according to the width of each CT slices. Finally, all these date were combined into one image data using surface and shadow treatment, and expressed on the computer screen. All these processes of reconstruction were performed with commercial base software.
The results were satisfactory not only for understanding the stereoscopic positions of each structures in temporal bone, but also for analysing the degree of bone destruction by cholesteatoma. This system was especially useful for determining the best type of surgery in difficult cases, such as in pyramidal cholesteatoma. In conclusion, three-dimensional reconstruction will have a great role in diagnosis and treatment of temporal bone disease.View full abstractDownload PDF (4703K) -

JOURNAL FREE ACCESSThis report includes three cases of glottic closure with central neural diseases. The first case in fifty-five-year-old male with olivo-pont-cerebellar degeneration who had a sudden onset of dyspnea after his gastric haemorrhage. Aftertracheostomy was performed, his dysphagia deterioated and cricopharyngeal myotomy and infra-hyoid myotomy were performed. Eventually, his dyphagia improved and tracheal Tshaped tube was inserted.
The second case is a seventy-one-year-old female. She was suspected to have striatonigral degeneration. In the beginning of her admission her glottis was not closed completely and her dyspnea gradually increased because her glottic closure was deteriorated. After she was tracheostomized, she also had light dysphagia which was soon improved and tracheal T-shaped tube was inserted.
The third case is a thirty-seven-year-old male diagnosed as Arnold-Chiari malfomation. After tracheostomy, T-shaped tube was inserted. The T-tube was tried to be taken out but failed. It was mainly because he lost his willing to have rehabilitation.
The tracheal T-shaped tube is useful in the cases of the glottic closure originated in central neural diseases if they do not have severe dysphagia.View full abstractDownload PDF (8408K) -

JOURNAL FREE ACCESSIn spite of a recent tendency of chronic sinusitis to be getting milder in Japan, we still see many cases of the disease which is very resistant to variable therapies.
Diffuse panbronchiolitis that is commonly in association with chronic sinusitis has been shown to be receptive to a new therapy recently. This is the long term administration of low dose erythromycin therapy. This method is now widely recognized in Japan in case of diffuse panbronchiolitis, however efficacy of the therapy to chronic sinusitis still remains unknown.
We tried this erythromycin therapy for 33 patients with chronic sinustis which were very resistasnt to other therapies.
The result was very encouraging. The therapy has revealed to be safe for both adults and children, and fairly effective (23 in 33).
We found that the therapy is also safe and effective to otitis media with effusion.View full abstractDownload PDF (1070K) -

JOURNAL FREE ACCESSThe paper present some statistics of the existing trends in taste-disturbance encountered under 111 cases comprising 55 male-and 56 female patients between January 1985 and December 1989.
Consideration is given to a good relationship between severity with related potential response to therapeutic intervention and possible pathogeneses, e.g. oral lesion, cephalic trauma, common cold, nervous-, olfactory-, drug induced-, ideogenetic-, cerebrovascular disorders and those of unknown origin. Of these, attention is drawn to nervous disorder with the highest incidence of all (27%) which is followed by oral lesion and disorders of unknown origin, wherein the mean threshold of electrogustometry, when examined etiologically, is found higher in cephalic trauma and drug induced disorders in contrast to systemic and ideogenetic disorders, where it is found of a lower level.
Relatively high and positive correlation in threshold between electrogustometry and filter paper disc test is directly concerned, particularly with its highlighted value identified in those areas innervated by chorda tympani.
It appeared that more than 60% of the cases under test showed a deficiency trait in Zn; and 8 of 9 cases successfully improved through ZnSO4 medication.View full abstractDownload PDF (832K) -
