“…OtoMimix ® is a hydroxyl-apatite cement that is primarily used as a bone filler and depends on mechanical adhesion to the bone it is applied on. 12 The others are glass-ionomer cement that has inorganic glass crystals and a polymerizing component, such as polyacrylate or polymethacrylate. Polymerizing agent of glass-ionomer cements chemically bond to tissue as well as a mechanical adhesion.…”

The aim of this study is to retrospectively evaluate the effects of bone cement stabilization of the stapedotomy prosthesis with respect to audiological results and incidence of prosthesis dislocation. Material and Methods: A retrospective analysis of 32 cases that were operated using the same surgical technique. Surgeries were done by the same surgeon under general anesthesia. Preoperative and postoperative audiograms between Group 1 and Group 2 were compared. Demographic data, the surgical status of the contralateral ear, surgical technique, bone cement fixation status, length of the prosthesis, and intraoperative complications were analysed. Pure tone average (PTA) gains, air-bone gap (ABG) improvements, and 8 kHz hearing level changes were calculated. Results: Out of 32 stapedotomies, 13 cases had bone cement stabilization. There was no age (p=0.388) or sex (p=0.704) difference between the groups. Both groups had significantly improved PTAs (p<0.001) and decreased ABG (p<0.001) values. But there was no difference between the groups (p=0.701). Also, there was no difference of 8 kHz hearing levels (p: 0.656). Three prosthesis dislocations were seen in the "no bone cement" Group 1 versus no dislocations in the "bone cement" Group 2. This difference was not significant (p=0.253). Conclusion: Bone cement stabilization of the stapedotomy prosthesis is a safe technique. Bone cement stabilization did not affect audiological outcomes and may offer a reduction in the incidence of prosthesis dislocation. However, studies with larger patient series and longer follow-up periods are needed.

“…This method, which requires a multidisciplinary collaboration between medicine and engineering, has previously been used to compare the strengths of different types of bone cement. 8 Kalcıoğlu et al used a universal testing machine to evaluate and compare the shear bond strengths (N/mm 2 ) of different GIBCs and one type of HA cement applied on fixed incuses. Their shear bond strength values with Ketac-Cem (3M ESPE, USA).…”

ABS TRACT Objective: Our aim in this study is to determine if a pretreatment could make bone cement connection stronger and reduce the failure rate. Material and Methods: Twenty-four 6-9 months old female rats were divided into 2 groups as "day 0" and "day 90". Four different applications were made to the 2x2 cm 2 surgical area. Freshly prepared glass ionomer bone cement (GIBC) was applied by removing the periosteum with bipolar in the first application, by keeping the perichondrium intact in the second application, by removing the periosteum with trichloroacetic acid (TCA) solution in the third application, and by removing the periosteum mechanically in the last application. After these rats were sacrificed on day 0 and day 90, mechanical tests were made to the bone cements and shear strength values were calculated by dividing the maximum measured forces by the apparent contact areas. Results: Although shear forces were higher on day 90 than on day 0 (p=0.007), subgroup analyses revealed that the differences were significant in only the subperiosteum group (p=0.003). According to the pairwise comparisons, subperiosteal bone cement application yielded significantly higher shear forces on day 90 compared to the others (p<0.003) while the supraperiosteum, TCA, and electrocoagulation groups were similar to each other. Conclusion: GIBC reached its highest shear strength with time after a subperiosteal application. We do not recommend any of the pre-treatments tried in this study over a supra periosteal application before a bone cement ossiculoplasty since no increase in shear strength could be obtained.

“…Glass ionomer cements took place in otology practice, especially in ossiculoplasty operations, since the 1990s. 10 Glass ionomer cements are one of the most used allograft processes. They are used to fill the defect between the long process of the incus and the stapes.…”

“…8 Several studies have shown that there was a considerable increase in the hearing quality of patients when the ossicular chain was rebuilt with GIC. [9][10][11][12] The ideal bone cement utilized for this objective ought to be moldable, effectively applied, quickly setting, nonpoisonous, fluid-resistant, fit for osteointegration, and ready to affect insignificant inflammation. 13 The present study aims to assess the use of GIC for the reconstruction of the long process of the incus.…”

Introduction Chronic suppurative otitis media is one of the most common causes of reversible conductive hearing loss which can lead to necrosis of the ossicles. The incus, especially its long process, is the most common ossicle affected. Objectives The present study aims to assess the use of glass ionomer cement for the reconstruction of the long process of the incus. Methods The present study was conducted on 27 patients with chronic suppurative otitis media with central perforation with dry and quiescent ears with an eroded long process of the incus submitted to tympanoplasty. The audiological evaluations were done on all patients, including preoperative and postoperative evaluation of the air-bone gap; the average pure tone threshold was done 6 months postoperatively. Results The average air pure tone threshold was 42.8 dB preoperatively and 22.5 dB postoperatively. The postoperative air pure tone thresholds were significantly smaller than the preoperative values (p < 0.01). The air-bone gap was 30.5 dB at 500 Hz, 31.6 dB at 1 KHz, and 24.1 dB at 2 kHz preoperatively, and 7.7 dB at 500 Hz, 7.2 dB at 1 KHz, and 7.1 dB at 2 kHz postoperatively at the end of 6 months of follow-up. There were significant hearing gains in the air-bone gap (p < 0.001). Conclusion Glass ionomer cement is a useful and effective material for bridging the defect of the long process of the incus.
