The most common postoperative complications related to BAHA prosthetic surgery are skin complications. In this study we compare and evaluate these reactions with two different surgical techniques, the BAHA dermatome and the U-graft technique.
Fifty-three patients who underwent implantation of a BAHA at our hospital between 2001 and 2008 were studied. The comparison of the skin reactions was carried out according to Holgers' classification. We also recorded the number of cures required until the skin was stabilized.
We used the dermatome in 27 patients and the U-graft in 26 patients. In the dermatome group we have reported a total of 74% of skin reactions (20 patients), in contrast with the 34% (9 patients) observed in the U-graft group. The average number of cures for patients in the dermatome group and those in the U-graft group was 4.1 and 2.7, respectively. The differences found were statistically significant and had a 95% confidence interval.
In our experience, the use of the electric dermatome in BAHA surgery offers a higher incidence of skin complications in comparison with the U-graft technique. Since both techniques have a number of advantages and disadvantages, it may be that the selection of the technique to be employed according the individual characteristics of each patient may offer better results in the future.
与骨锚式助听器（BAHA）假体手术相关的最常见术后并发症是皮肤并发症。在本研究中，我们比较并评估了两种不同手术技术（BAHA皮刀技术和U型移植技术）引发的这些反应。
对2001年至2008年间在我院接受BAHA植入手术的53例患者进行了研究。根据霍尔格斯分类法对皮肤反应进行比较。我们还记录了皮肤稳定前所需的治愈次数。
我们对27例患者使用了皮刀技术，对26例患者使用了U型移植技术。皮刀技术组共报告了74%的皮肤反应（20例患者），相比之下，U型移植技术组为34%（9例患者）。皮刀技术组患者和U型移植技术组患者的平均治愈次数分别为4.1次和2.7次。发现的差异具有统计学意义，且置信区间为95%。
根据我们的经验，与U型移植技术相比，在BAHA手术中使用电动皮刀会导致更高的皮肤并发症发生率。由于两种技术都有一些优缺点，未来根据每位患者的个体特征选择使用的技术可能会取得更好的效果。
