ジャーナル フリーWe measured PO2 in the middle ear effusion (MEE) of patients with mucoid otitis media with effusion (M-OME), serous otitis media with effusion (S-OME) and middle ear barotrauma (MEBT). The mean value of PO2 were 23.3 mmHg in MOME,27.4 mmHg in S-OME and 38.2 mmHg in MEBT.
The PO2 value in middle ear air depends on t h e ventilatory function of Eustachian tube. When the ventilatory function of Eustachian tube is highly impaired,O2 tension in the middle ear air depends on the condition of middle ear mucosa. When the middle ear cavity has abnormal mucosa, there is no O2 exchange between the middle ear mucosa and middle ear air. The Eustachian tube function is highly impaired in OME, but slightly in MEBT, so the PO2 value is low in M-OME, but relatively high in MEBT.抄録全体を表示PDF形式でダウンロード (1072K) -

ジャーナル フリーRadioactive Xe gas insuffiated via the Eustachian tube (ET) entered the middle ear cavity, suggesting the role of middle ear ventilation. Morphological and enzymehistochemical studies revealed that there were abundant vessels and glands with autonomic nervous fibers in the pharyngeal orifice of the ET. As therapy applied to the pharyngeal orifice of the ET, CO2-laser irradiation and injection of steroid hormone were performed in a patient of tubal dysfunction and otitis media with effusion and good results were obtained. The above fundamental and clinical data indicate the participation of the pharyngeal orifice of the ET in middle ear ventilation.抄録全体を表示PDF形式でダウンロード (18190K) -

ジャーナル フリーAn experimental study on aeration in the epitympanum through the tympanic isthmus was done using human cadaver temporal bone specimens. The tegmen tympani of the temporal bone specimen was opened and covered by wrapping film to observe the attic from above. A thin metal tube was inserted into the Eustachian tube through which smoke was blown. The locus of the smoke flow was observed from above, and recorded by video tape. The epitympanum is divided into the anterior, the medial and the lateral portions by two kinds of vertical type mucosal fold. Normal specimens aeration at the lateral space of the epitympanum was the poorest and delayed. In specimens with a narrowed isthmus, this phenomenon was enhanced. In contrast, in specimens with an enlarged isthmus or aditus, aeration at the lateral space was improved as well as in the entire epitympanum. It is concluded that the lateral portion of the attic is closely related to the delayed aeration, followed by the development of the attic type cholesteatoma.抄録全体を表示PDF形式でダウンロード (10231K) -

ジャーナル フリーThe effect of chronic middle ear inflammation on the pneumatization of the tympanic bulla was investigated in pigs. The pig tympanic bulla has an air cell system that is divided by trabeculae, and closely resembles the human mastoid air cell system. The tympanic bulla and its air cell system in normal ears were well developed because of the bone formation and the bone resorption inside the cortex. On the other hand, the tympanic bulla affected by chronic otitis media in young pigs exhibited reduced pneumatization arising from impaired bone resorption, and the later otitis media developed, the more the air cell system was preserved. It was concluded that the occurrence of chronic middle ear inflammation in the early stages of life causes inhibition of pneumatization by hindering the development of the air cell system, and the degree of the inhibition was related to the time of the onset of the disease.抄録全体を表示PDF形式でダウンロード (16138K)
