Ossiculoplasty for Tympanosclerosis

Development and Validation of a Clinical Score for Predicting the Risk of Tympanosclerosis Before Surgery

“…This could be caused by the middle ear mucosa being extensively involved in tympanosclerosis, resulting in suppressed mucus secretion. 1,9 The OR of dry ear was 3.45 (1.67-7.88, P ¼ .002) in our univariate regression analysis. However, it was not significant on multivariate regression analysis, possibly because of the correlation between variables.…”

“…Some of them may be just myringosclerosis, and this type of calcification does not have to be removed during surgery. 9 Although it is time consuming and somewhat difficult to clean up calcification on both sides of the malleolus, in our opinion, it is worthwhile to loosen the ossicular chain and obtain better postoperative hearing improvement. 9 In clinical practice, the mean ABG is used to assess the degree of hearing loss, but we found that patients with chronic otitis media, especially those with tympanosclerosis, have a greater ABG at low frequencies (Figure 3).…”

This finding is very similar to the study by Kikkawa et al, who observed frequency- dependent hearing loss in patients with an immobile ossicular chain, which is more significant at lower frequencies and preserved better at 2000 Hz.…”

“…7,8 However, for patients with tympanosclerosis, surgery should be performed with caution, because in many cases it is much more complicated than for patients without tympanosclerosis. 9 The calcified plaques which alter the compliance of the tympanic membrane and limit the mobility of the ossicles, need to be removed during the surgery. 10,11 Therefore, the perforation of the tympanic membrane would become larger, which increased the difficulty of healing.…”

Comparison of hearing reconstruction techniques in tympanosclerosis with stapes fixation

“…The main question in the management of tympanosclerosis is whether to force mobilization or perform a stapedotomy. The reasons for this discussion are the risk of sensorineural hearing loss and facial nerve damage [17]. Some authors favor mobilization and others favor stapedotomy [3,7,8].…”
