Comparison of hearing outcome using a Nitinol versus Teflon prosthesis in stapedotomy

Abstract

There was no significant difference between the two groups in the postoperative air-bone gap and air-bone gap closure at 1, 2, 3, and 6 months.

A systematic review of the effect of different crimping techniques in stapes surgery for otosclerosis

“…; date of last search was April 6, 2015). We included 22 articles after selection based on title and abstract and subsequent full text screening . No articles were excluded based on language, nor were any articles excluded because we could not retrieve the full‐text version.…”

“…This study also reported statistically significant results. In two studies that reported statistically significant results and in four studies without statistically significant results, it was not clear how postoperative air‐bone gaps were calculated.…”

“…Criteria that scored predominantly unsatisfactory or unclear were randomization, blinding, and standardization of treatment. At present, only one randomized trial is available that compared prostheses with different crimping methods . All of the other studies were cohort studies.…”

“…In 10 studies, the mean difference in preoperative air‐bone gap ranged between 0 and 4 dB and was not statistically significant . In two studies, mean preoperative air‐bone gap was reported, but no details on statistical significance were reported . Differences in mean preoperative hearing thresholds may confound treatment effects.…”

“…We included 22 articles after selection based on title and abstract and subsequent full text screening. [7][8][9][10][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] No articles were excluded based on language, nor were any articles excluded because we could not retrieve the full-text version. One additional article 36 was identified through cross-reference checking.…”
