速看!东亚鼻整形术中鼻背自体移植物的长期再吸收率

2022-02-02 MedSci原创 MedSci原创

对自体移植物的长期随访研究很少。因此,本研究的目的是评估各种自体移植物在上鼻三分之一处的长期再吸收率。

与同种异体和同种异体植入物相比,自体材料具有较高的生物相容性和较低的感染风险,因此在鼻整形术中仍是首选的移植材料。近年来,隆鼻背的发展趋势强烈倾向于使用自体组织。

可见软骨移植物在亚洲鼻整形术中被广泛使用,尽管同种异体植入物由于自体嵌体植入的吸附性仍被用于隆鼻背。在亚洲鼻整形术中,许多外科医生面临着选择正确的自体移植以达到最佳效果的困难。

对自体移植物的长期随访研究很少。因此,本研究的目的是评估各种自体移植物在上鼻三分之一处的长期再吸收率。

图1 文章来源

研究团队回顾性分析了2009年至2018年间使用自体组织行鼻中隔成形术伴隆鼻背的患者的病历。将应用于鼻背的自体移植物分为三组:乳突浅筋膜卷曲组、乳突浅筋膜包裹的软骨切片组和骶骨真皮卷曲组。术前和术后的照片用于评估吸收率和隆起高度。

图2 指标示意图

结果显示,与其他两组相比,卷皮组的术后隆鼻高度显著增加,但长期随访隆鼻高度显著下降。在这三组中,鼻内径点(p < 0.001)和½鼻内径点(p < 0.001)有统计学意义的趋势差异,但鼻内径点无统计学意义。

图3 基线、术后1个月和长期随访的预测趋势差异(F/U)。

三组中,卷皮骶真皮层组最突出,乳突浅筋膜包裹切片软骨组次之。乳突浅筋膜组的吸收率最高(p < 0.001)。至于其他两组的吸收率,卷皮组的吸收率高于软骨切块包覆乳突浅筋膜组。

表1 人体测量学分析和病人的手术结果

在几乎所有的组中,在长期观察中至少有50%的再吸收。

再吸收问题无疑是亚洲鼻整形术的最大绊脚石。正确选择自体材料,在过度矫治和再吸收预测之间做出正确的选择,可以决定手术的成功或失败。
