During the past six years, we have treated 406 patients with classical silicon augmentation rhinoplasty. The types and incidence of complications after subcutaneous or subfascial implantation were examined and discussed. We proposed that most complications are related to the depth of the implant and the character of the tissues. In order to improve our operation and prove our hypothesis, we performed subperiosteal augmentation rhinoplasty in 22 cases with satisfactory results. At the same time, we investigated the biomechanical properties of human nasal periosteum and fascia, including tensile strength, stress-strain relationship and stress relaxation characters under uniaxial tension. Although less elastic, the periosteum has more tensile strength than fascia. So, in the view of biomechanics, the periosteum is thicker, tougher, and stiffer than fascia, thus more suitable for covering silicon implants.
在过去六年中，我们对406例患者进行了经典的硅胶隆鼻术。对皮下或筋膜下植入后的并发症类型及发生率进行了检查和讨论。我们提出，大多数并发症与植入物的深度和组织特性有关。为了改进我们的手术并验证我们的假设，我们对22例患者进行了骨膜下隆鼻术，效果令人满意。同时，我们研究了人鼻骨膜和筋膜的生物力学特性，包括拉伸强度、应力-应变关系以及单轴拉伸下的应力松弛特性。虽然骨膜的弹性较小，但其拉伸强度比筋膜大。因此，从生物力学角度来看，骨膜比筋膜更厚、更坚韧、更硬，因而更适合覆盖硅胶植入物。
