Bone cement in ossicular chain reconstruction: systematic review and meta-analysis.

ABSTRACT

OBJECTIVES: To compare the hearing outcomes of ossicular chain reconstruction using bone cement versus other materials such as prostheses and autografts. METHODS: This study included articles that compared hearing outcomes in patients with conductive hearing loss who underwent stapes revision surgery or chronic otitis media surgery. A systematic search for articles from January 2000 to February 2022 was conducted in Medline, Embase, and Cochrane Library databases. Only articles in English were included. An effective postoperative air-bone gap (ABG) was defined as ≤20 dB. A bias assessment tool was developed according to Cochrane guidelines, and the chi-square test was used to evaluate the mean age of the samples. RESULTS: Of the 418 studies that met the selection criteria, only seven were eligible for this study, consisting of 187 patients in the bone cement group and 173 in the non-bone cement group. Ossiculoplasty using bone cement yielded significantly better results, with a combined odds ratio (OR) of 2.03 (95% CI 1.16-3.55, p = 0.01). CONCLUSIONS: The results of this study suggest that the effectiveness of bone cement in ossiculoplasty was greater than that of other materials in chronic otitis media surgery or stapes revision surgery, with a higher number of patients achieving ABG ≤20 dB.
