Tympanosclerosis of the middle ear: Late results of surgical treatment

“…Zollner (1969) states: 'We cannot be too proud of our results. If 93 per cent had a hearing gain, we must confess that the gain was not always satisfactory.…”

“…Since stapediolysis was the predominant type of operation in the series by Zollner (1969), a direct comparison of the two series appears relevant. Zollner (1969) states: 'We cannot be too proud of our results. If 93 per cent had a hearing gain, we must confess that the gain was not always satisfactory.…”

“…The clinical term "tympanosclerosis of the middle ear' was first defined by Troltsch (1869) as a stiffness of the fibrous tissue in the deepest layer of the middle ear mucosa fixing the stapes in the oval niche and/or the malleus and incus in the attic. Actual clinical recognition of tympanosclerosis first began with Zollner and Beck (1955) and was followed by numerous clinical and histological reports on aetiology, pathogenesis, in relation to cholesteatoma as well as treatment methods (Zollner 1956(Zollner , 1963(Zollner , 1969House and Sheehy, 1960;Goodhill, 1960;Sheehy and House, 1962;Chang, 1969;Friedmann, 1971;Smyth, 1972).…”

“…The following surgical priniciples have been employed in middle ear tympanosclerosis in cases with stapes fixation: (a) removal of tympanosclerotic masses Accepted for publication: 30 June 1990. piece by piece and stapediolysis, (b) stapedectomy, or (c) stapedotomy. Zollner (1963Zollner ( , 1969 recommended removal of tympanosclerotic masses piece by piece with mobilization of the stapes and reported a primary hearing gain of 10 dB or more in 93 per cent of the cases. Charachon et al (1981) recommended removal of the tympanosclerotic masses from the ossicles, mobilization of the malleus and incus at the first operation, and mobilization of the stapes and interposition at the second stage.…”

Miringosclerose em pacientes com insuficiência renal crônica: análise comparativa com um grupo controle

“…1,5,11,15,16 The etiology and pathogeny, and the reasons why only some patients develop this type of process, are not fully understood. A few studies have attempted to establish an etiological and pathogenic association with certain factors; the papers published by Schiff et al, 17 and Schiff & Yoo, 18 describe a relation between tympanosclerosis and the autoimmune reaction, and by Koç & Uneri, 19 have raised the hypothesis that there might be a genetic predisposition.…”
