Objective To compare the efficacy and safety characteristics of different materials used for oval window sealing during stapedotomy. Methods A systematic review was conducted according to the PRISMA guidelines. Published international English literature from January 1, 2000 to December 2021 was screened, checking for studies that compared different materials utilization in patients undergoing stapedotomy surgery for otosclerosis or congenital stapes fixation. Data related to the efficacy and safety of each material were extracted. The primary outcome measure was the air–bone gap (ABG) closure after surgical intervention. Results Six studies were included in the metanalysis. Because of the heterogeneity of the treatments adopted, we assessed the use of the fat compared to all other treatments, and the use of the gelfoam compared to all other treatments. In the former analysis (fat vs others) we did not identify differences in ABG closure between the groups (p = 0.74), with a low heteroge- neity of the results (I2 = 28.36%; Hedge’s g = 0.04, 95% CI − 0.19 0.27); similarly, we did not identify differences between the use of gelfoam and other treatments (p = 0.97), with a low heterogeneity of the results (I2 = 28.91%; Hedge’s g = 0.00, 95% CI − 0.20 0.21). Conclusions Numerous options are available for oval window sealing during stapedotomy, with acceptable safety and effec- tiveness profiles. Based on the current data, no definitive recommendation can be made regarding the choice of one material over another, and the convenience of sealing over no sealing at all.

Abstract

Objective To compare the efficacy and safety characteristics of different materials used for oval window sealing during stapedotomy. Methods A systematic review was conducted according to the PRISMA guidelines. Published international English literature from January 1, 2000 to December 2021 was screened, checking for studies that compared different materials utilization in patients undergoing stapedotomy surgery for otosclerosis or congenital stapes fixation. Data related to the efficacy and safety of each material were extracted. The primary outcome measure was the air–bone gap (ABG) closure after surgical intervention. Results Six studies were included in the metanalysis. Because of the heterogeneity of the treatments adopted, we assessed the use of the fat compared to all other treatments, and the use of the gelfoam compared to all other treatments. In the former analysis (fat vs others) we did not identify differences in ABG closure between the groups (p = 0.74), with a low heteroge- neity of the results (I2 = 28.36%; Hedge’s g = 0.04, 95% CI − 0.19 0.27); similarly, we did not identify differences between the use of gelfoam and other treatments (p = 0.97), with a low heterogeneity of the results (I2 = 28.91%; Hedge’s g = 0.00, 95% CI − 0.20 0.21). Conclusions Numerous options are available for oval window sealing during stapedotomy, with acceptable safety and effec- tiveness profiles. Based on the current data, no definitive recommendation can be made regarding the choice of one material over another, and the convenience of sealing over no sealing at all.
