Abstract

Objectives: In this study, we investigated whether the use of double layer graft (DLG) in tympanoplasty would increase grafting success rates (GSR) and whether increased graft thickness would negatively affect hearing.

Methods: The study group consisted of patients with DLG and the control group consisted of patients with single layer graft (SLG). The results of 195 patients in terms of hearing achievement and 211 patients in terms of GSR were compared.

Results: Hearing and GSR were analyzed in 103 DLG and 108 SLG patients. Postoperative 6th month air conduction pure tone averages were 25.34 (±14.99) dB in DLG group and 20.50 (±8.82) dB in SLG group. These values were statistically significantly higher in the DLG group (p=0.005). Postoperative air bone gap was 11.40 (±8.61) dB in DLG and 12.95 (±10.88) dB in SLG and there was no statistically significant difference in hearing gain between the groups. GSR was 99/103 (96.1%) in the DLG group and 103/108 (95.4%) in the SLG group with no difference between the groups (p=0.679) CONCLUSION: We concluded that DLG is not superior to SLG in terms of both hearing and GSR, and may even be disadvantageous in terms of hearing, and this should be taken into consideration in patient selection.

单层和双层鼓室成形术对听力和移植成功率的影响。

目的：在本研究中，我们探讨在鼓室成形术中使用双层移植物（DLG）是否会提高移植成功率（GSR）以及增加移植物厚度是否会对听力产生负面影响。方法：研究组为DLG患者，对照组为单层移植（SLG）患者。比较195例患者的听力成绩和211例患者的GSR。结果：对103例DLG和108例SLG患者的听力和GSR进行分析。术后6个月，DLG组空气传导纯音平均值为25.34（±14.99）dB， SLG组为20.50（±8.82）dB。这些数值在DLG组有统计学意义（p=0.005）。DLG组术后气骨间隙为11.40（±8.61）dB， SLG组术后气骨间隙为12.95（±10.88）dB，两组听力增益差异无统计学意义。DLG组的GSR为99/103 (96.1%)，SLG组的GSR为103/108(95.4%)，两组间差异无统计学意义（p=0.679）。结论：DLG在听力和GSR方面均不优于SLG，甚至可能在听力方面处于劣势，在选择患者时应考虑到这一点。
