用助听器掩蔽控制严重的双侧耳鸣

有些耳鸣者戴助听器效果良好。这可能是由于放大了的外界噪声掩蔽的作用。报告一例61岁女性患者,为重度双侧感觉神经性聋及左耳耐受级降低。同时有重度双侧耳鸥,且夜间更重,影响睡眠。戴NHS耳后BE 12型助听器于左耳,对语言识别率无明显帮助,但耳鸣稍减轻。右耳用一高功率助听器Amplivox Powervox 1,语言识别率明显改善,该耳耳鸣完全消失。同时在左耳戴BE 12助听器,双耳鸣均消失。一周后复查,有持续长时间的后效抑制(residual inhibition),耳鸣未再发生。又一周后,右耳仍无耳鸣,左耳戴助听器时有轻度

Movement of the ear ossicles by middle ear muscle contraction

Up to now, the function of the middle ear muscles has mainly been investigated from an acoustical point of view. However, the primary function of the middle-ear muscles, namely the induction of ossicular movements, has never been investigated systematically. For this purpose, the displacements of the ossicles, as induced by simulated muscle contractions, were measured microscopically in 13 fresh temporal bone preparations. Both muscles move all ossicles. The tensor tympani muscle pulls the umbo inwards about 100 microns. Due to the gliding motion in the malleus-incus joint, the stapes is thus pushed inwards by at the most 10 microns and, additionally, displaced anteriorly, antagonistic to the pull of the stapedius muscle. This muscle pulls the stapes backwards, lifting the anterior crus outwards and pushing the posterior crus inwards. This reduces the pressure on the cochlear fluids significantly as compared to our former concepts of the movement of the footplate, tilting outwards as a whole around an axis at the posterior pole. Furthermore, this outward displacement of the stapes is not prerequisite for the outward movement of the malleus-drumhead complex, which typically appears at the contraction of the stapedius muscle. The basic motion of the stapes is the movement backwards, which is 5 times greater and which matches the anatomic direction of the pull of the stapedius muscle. This explains the otherwise unlogical position of the stapedius muscle parallel to the footplate. Due to the gliding movement in the malleus-incus joint, this motion changes at the umbo into outward rotation, counteracting the tensor tympani muscle.(ABSTRACT TRUNCATED AT 250 WORDS)     

Malignancies of the ear

Cancer of the ear is an uncommon occurrence and rarely diagnosed early in its development. Routine biopsy of all granulomatous and neoplastic diseases of the ear is essential to early diagnosis. Polytomography is an aid in documenting the extent of the disease in bone. The surgical anatomy of the region of the ear imposes special disadvantages upon any type of surgical technique employed and supervoltage irradiation given. Temporal bone resection and its modifications, combined with irradiation, enhance the cure rate in the advanced cases and add significantly to the local control of this disease. A review of 273 cases is presented.     

Lymphoma in the ear

BACKGROUND: Malignant tumors of the ear are rare. The most common malignant tumors are squamous cell carcinomas and adenocarcinomas. Lymphoma in the ear is rare. METHODS: We report 2 cases of a primary presentation of a lymphoma of the ear. The literature since 1947 is reviewed. RESULTS: An 83-year-old woman with an anaplastic large cell lymphoma of the skin of the external auditory meatus and a 75-year-old man with a B-cell non-Hodgkin's lymphoma of the mastoid process are presented. The literature review shows that only 16 cases of lymphomas of the ear have been reported so far. CONCLUSIONS: In a case of therapy-resistant otitis and/or peripheral facial paralysis malignancy should be excluded by computer tomography of the mastoid. For histopathological diagnosis unfixed specimens are preferable. Uniform treatment of lymphomas of the ear has not been established.
