“…In relation to sex, it was found a predominance of females, similar to what is widely described in the international literature 12 . In several studies consulted in our literature review, a decrease in ABG (GAP or air-bone space) to less than 10dB (decibels) is considered successful in stapes surgery [12][13][14] . In our evaluation, we observed that of the patients who did con-tinue with their postoperative follow-up with the Audiology service, approximately half of each group achieved this goal by having as a postoperative result an ABG less than 10dB.…”

BACKGROUND. Otosclerosis is a primary disease of the human otic capsule and stapes stage, being a frequent cause of conductive hearing loss in our country. The surgical treatment of choice is stapes surgery and prosthesis placement, performed in a conventional way, with a surgical microscope, for 30 years in our hospital. Recently, the option of performing stapes surgery endoscopically was introduced in our centre. OBJECTIVE. To evaluate the results in stapes surgery for otosclerosis between the conventional microscopic versus endoscopic procedure. MATERIAL AND METHODS. An observational, analytical and retrospective study on patients undergoing stapes surgery with microscopic and endoscopic technique was conducted. Data such as age, sex, state of origin, affected ear, as well as the technique used, duration of surgical intervention, hearing gain and postsurgical complications were taken. Data were taken from the records of patients admitted to the hospital. Descriptive statistics, Mann-Whitney U and Pearson’s Ji2, were used, considering a value of p≤ 0.05 as significant. RESULTS. No significant differences were found in surgical time or postoperative hearing between the two surgical techniques. The female sex was the most intervened. There was no significant difference between the post-surgical complications of both groups. CONCLUSION. Both procedures appear to be effective, with similar risks and postoperative results for the surgical treatment of otosclerosis.

“…The parameters of the model, derived from the epidemiological analysis, are presented in Table 2 . 2 , 4 , 7 , 8 , 12 , 26 , 36 For the hearing aid group, costs were determined on a yearly basis, with a new device every 4 years ( Table 2 ). Based on audiologists’ estimates and sales figures provided by the Syndicat National de l’Industrie des Technologies Médicale, we assumed that 20% of patients using a hearing device would choose a class I device (the minimum target set by the state for audiologists in France), 35% would choose a class II, subgroup C or D device (class II), and 45% would choose a class II, subgroup E or F device (class III).…”

IMPORTANCE Surgery and hearing aids have similar outcomes in terms of hearing acuity but differ in terms of cost, aesthetics, and patient quality of life. The cost-effectiveness and budget impact of otosclerosis treatments have never been studied in Europe.OBJECTIVES To compare the estimated mean costs per patient over 10 years of surgery vs hearing aids for the treatment of otosclerosis and to estimate the budget impact of an increase in the proportion of patients receiving surgical treatment. DESIGN, SETTING, AND PARTICIPANTS This economic evaluation analyzed French and Europeanepidemiological data on the surgical management of symptomatic otosclerosis and compared them with data from the literature to build economic models. The analysis was conducted in January 2021.EXPOSURES Two care pathways were considered in the treatment of otosclerosis, either hearing aid or surgery. MAIN OUTCOMES AND MEASURESCosts were studied over 10 years using Markov models of the 2 care pathways (hearing aid vs surgery). The budget impact analysis was performed over 5 and 10 years, assuming a 1-percentage point yearly increase in the proportion of patients receiving surgical treatment. RESULTSOver 10 years, the estimated mean cost per patient was significantly lower in the surgery group compared with the hearing aid group (€3446.

Numerical Analysis of Stapes Prosthesis Constraining in the Case of Otosclerosis

et al. 2021

In the case of otosclerosis, it has been noticed that even though there are a variety of different prostheses on the market, due to the anatomical characteristics, it is not always possible to restore excellent mobility to the ossicles and the prosthesis. On the one hand, this happens because the incus long process and the prosthesis create difficult angles. On the other hand, incus necrosis is among the most common causes of the loss of stability to the prosthesis and stapedectomy failure. The aim of this research is to suggest an improvement for stapes prosthesis stability and numerically evaluate the impact of the prosthesis constraining to its dynamical behavior. Numerical 3D models of a standard as well as a modified (adjustable angled) stapes prosthesis were created in order to achieve this aim. Consequently, the modal analysis has been performed to evaluate the mechanical behavior of the prosthesis, assuming that the piston (thick part) would be made of Teflon, and the thin part, fixated on the incus long process, would be made from titanium alloy. Finally, the numerical analysis has been conducted by changing the boundary conditions in respect of the prosthesis constraining, where the attached stapes prosthesis connects to the ossicular chain. Subsequently, there were two hypotheses raised for the prosthesis loop constraining. The first is that during the surgery, the prosthesis is perfectly crimped with certain looseness. The second is that the prosthesis is outgrown by the tissues over time and thus becomes over-constrained. Then, the analyzed standard stapes prosthesis does not fulfil its functions because of the over-constraining that develops over time. An improvement for the standard stapes prosthesis, i.e., a modified stapes prosthesis (adjustable angled), that has been proposed in this research allows avoidance of the negative effects of the over-constrained standard stapes prosthesis that appear over time. Moreover, the proposed modified prosthesis helps to regain hearing when the angle between the incus long process and prosthesis is unfavorable.
