“…To prevent such incidence gelfoam is placed over the stapes footplate and the facial nerve during the process of application. [11,12] Another advantage of bone cement that it got no interference regarding graft take rate. [13] in our cases we used gelfoam as supporting material when tympanic membrane grafting is done, this gives protection against contact between the tympanic membrane and the bone cement.…”

Objective: to evaluate the hearing outcomes of using ionomeric bone cement in re-bridging incudostapedial joint discontinuity. Methods: This study included 50 patients who had ossiculoplasty using ionomeric bone cement for re-bridging of incudostapedial joint. There pre and post-operative audiologic outcomes were evaluated and reviewed by using pure tone audiometry averages and the air bone gap values with a follow up period of one year. Results: 42 patients (84%) had a post-operative air bone gap less than 20 dB following one year of surgery. The pre and post-operative mean of pure tune averages were 50.04±7.28 and 32.74±7.07 respectively (P value<0.01). The pre and post-operative mean of air bone gap were 36.56±6.41 and 17.60±5.77 respectively which was statistically significant (P value<0.01). Conclusion: using of ionomeric bone cement is a good grafting material in incudostapedial re-bridging ossiculoplasty being cost effective, easy applicable and biocompatible and give a satisfactory hearing outcome in selected patients.

“…Due to the potential neurotoxicity of glass ionomeric cement, contact with neural structures, perilymph or dura should be avoided 4 , 10 . In the event of contamination, bone cement should be aspirated instantly and multiple attempts at aspiration and irrigation of the middle-ear cavity with serum is essential to extract the bone cement 11 .…”

“…Although bone cement has a neurotoxic effect by increasing inflammation and the formation of granulation tissue, Kum and Kulacoglu reported that it does not give rise to permanent dysfunction of facial nerves 10 . The heat produced in the preparation of bone cement is perhaps another disadvantage of bone cement.…”

ObjectiveThis study aimed to evaluate the long-term results of ossiculoplasty using bone cement.MethodForty patients (24 females and 16 males; mean age: 34.1 ± 11.8 years; range, 9–54 years) with chronic otitis media with perforation but without cholesteatoma who had undergone incudostapedial rebridging ossiculoplasty using bone cement were evaluated retrospectively. Pre-operative and post-operative audiograms were evaluated. Bone conduction, air conduction and air–bone gaps were calculated according to international guidelines.ResultsThere was a mean reduction in pre-operative and post-operative air conduction (12.30 ± 11.98 dB), and this result was significant (p = 0.0001). There was a mean reduction in pre-operative and post-operative bone conduction (4.30 ± 6.69 dB), and this result was significant (p < 0.0001). The pre-operative air–bone gap was 27.65 dB and decreased to 19.65 dB during follow-up (p = 0.0001). No adverse reactions or complications were observed.ConclusionBone cement is reliable for the repair of incudostapedial-joint defects.

“…The authors reported that GIC caused foreign body reaction, increased inflammation, and granulation tissue formation around the nerve, but it did not lead to a permanent facial nerve dysfunction. 21 In case of any contamination of GIC with neural structures, GIC should be suctioned carefully and tympanic cavity should be irrigated with sterile saline. In our study, we did not observe any serious complication associated with GIC.…”

The aim of this study was to investigate the functional results of glass ionomer cement (GIC) and incus transposition (IT) used for treatment of incus long process defects in pediatric patients. The medical records of 40 patients, aged 10 to 16 years, who underwent ossicular reconstruction due to incus long process defect between January 2010 and July 2017 were reviewed for age and gender, types of ossiculoplasty technique, types of graft used for tympanic membrane repair, preoperative-postoperative audiological examinations, and length of follow-up. The mean preoperative air-bone gap (ABG) was 29.40 (8.47) dB, the mean postoperative ABG was 15.25 (8.55) dB in the entire group, and the difference was statistically significant (P < .001). The functional outcome (ABG 20 dB) was 80% (32 patients) in the entire group. The mean hearing gain was 18.83 (9.43) dB and postoperative mean ABG was 20 dB or better in 17 (94.4%) patients in the GIC group. The mean hearing gain was 10.31 (9.44) dB, and postoperative mean ABG was 20 dB or better in 14 (63.6%) patients in the IT group. The mean hearing gain was significantly higher in the GIC group than in the IT group (P ¼ .026), and the postoperative mean ABG was significantly higher in the IT group than in the GIC group (P ¼ .045). The functional success rates were significantly higher in GIC group than in IT group (P ¼ .020). There were no statistically significant differences between groups in terms of postoperative speech reception threshold and word recognition scores (P ¼ .628, P ¼ .260, respectively). The graft success rates were 94.4% (17 patients) in the GIC group and 90.9% (20 patients) in the IT groups. There was no statistically significant difference between groups in operated side (P ¼ 1.000). Reconstruction of small incus long process defects using GIC is a valuable technique and can be safely used in pediatric patients. The hearing outcomes are significantly better in GIC rebridging technique when compared with a sculpted IT technique.

Effects of glass ionomer cement on facial nerve: a clinical and histopathologic evaluation

Abstract: Bone cement directly applied on the nerve causes foreign body reaction increased inflammation and granulation tissue. Nonetheless it does not lead to a permanent facial nerve dysfunction.
