Tympanosclerosis of the stapes hearing results for various surgical treatments
Otolaryngology-Head and Neck Surgery, 1992Co-Authors: Neil A Giddings, John W HouseAbstract:When Tympanosclerosis involves the tympanic membrane or the lateral ossicles, treatment is usually straightforward and uncomplicated. When the stapes is involved, therapy Is more controversial and may be more difficult. We report our results in 154 patients who underwent different surgical procedures for Tympanosclerosis of the stapes. Followup was up to 10 years. Pure-tone average threshold was significantly improved (P < 0.05) in patients who underwent mobilization procedures or stapedectomy for definitive treatment. The air-bone gap was less than 20 dB at 6 months postoperative in 72% of patients and less than 30 dB in 90%. At 6 months, 2 years, and 5 years there were no statistically significant differences in hearing results between stapedectomy and mobilization patients, some of whom were followed for up to 10 years. No patient had a profound hearing loss after surgery. Surgical treatment for Tympanosclerosis of the stapes is a safe procedure, with hearing results similar to those of surgery for oth...

aspirating middle ear effusions when inserting ventilation tubes does it influence post operative otorrhoea tube obstruction or the development of Tympanosclerosis
Clinical Otolaryngology, 1991Co-Authors: P J D Dawes, B J Bingham, R Rhysj, M V GriffithsAbstract:: This prospective study examined the influence of aspirating middle ear effusions, immediately prior to ventilation tube insertion, upon the subsequent development of otorrhoea and Tympanosclerosis. 50 children were studied and aspiration of effusions did not influence the incidence of purulent otorrhoea or ventilation tube obstruction within 1 month of surgery. The development of Tympanosclerosis did not correlate with effusion aspiration, but in those ears which had an effusion aspirated there was a relation between operative bleeding and the development of Tympanosclerosis.

intra tympanic membrane bleeding after grommet insertion and Tympanosclerosis
Clinical Otolaryngology, 1990Co-Authors: Andrew J Parker, Judith E PowellAbstract:: The aetiology of Tympanosclerosis following grommet insertion remains controversial. In this study tympanosclerotic changes of the tympanic membrane in 92 ears were shown to be related to the presence of intra-epithelial haemorrhage shortly after myringotomy with grommet insertion (P less than 0.01) and to the grommet being in situ on follow-up 6 months later (P less than 0.025). Ears in which haemorrhage was absent and where the grommet had extruded did not develop Tympanosclerosis. These findings would indicate that bleeding, if causally implicated is not the sole aetiological factor, but careful attention to surgical technique to reduce this may subsequently minimize the development of tympanosclerotic changes.

pathogenesis of Tympanosclerosis
Otolaryngology-Head and Neck Surgery, 1993Co-Authors: M H Bhaya, P A Schachern, T Morizono, M M PaparellaAbstract:In spite of the wealth of information on the clinical, histologic, and pathologic aspects of Tympanosclerosis, the pathogenesis of Tympanosclerosis is still unclear. In an attempt to understand the pathogenesis, 319 human temporal bones from 196 individuals with otitis media were studied. The extent and nature of Tympanosclerosis and the characteristics of the otitis media associated with it were studied. Forty-five temporal bones from 35 individuals with otitis media were found to have Tympanosclerosis, giving an incidence of 14.1%. It was seen most commonly in individuals over 40 years of age (86.7%). The male-to-female ratio was 1.6:1. The most common site of occurrence was the tympanic membrane (88.9%). Tympanosclerosis was seen more often in the anterior and posterior inferior quadrants of the tympanic membrane and that, too, in a central position. Tympanosclerosis was seen more commonly in temporal bones with irreversible inflammatory changes, and in this group, late plaques were more commonly seen ...

Pathogenesis of Tympanosclerosis.
Otolaryngology--head and neck surgery : official journal of American Academy of Otolaryngology-Head and Neck Surgery, 1993Co-Authors: M H Bhaya, P A Schachern, T Morizono, M M PaparellaAbstract:In spite of the wealth of information on the clinical, histologic, and pathologic aspects of Tympanosclerosis, the pathogenesis of Tympanosclerosis is still unclear.

Tympanosclerosis was seen more commonly in temporal bones with irreversible inflammatory changes, and in this group, late plaques were more commonly seen than early or intermediate plaques. Audiometric charts failed to show any direct relationship between extent of Tympanosclerosis and the severity of hearing loss. The only audiometric finding of any consequence was a mixed hearing loss in the presence of middle ear Tympanosclerosis.
