During the past 6 years the authors have treated 406 patients with classic silicone augmentation rhinoplasty. The types and incidence of complications after subcutaneous or subfascial implantation are examined and discussed. They propose that most complications are related to the depth of the implant and the character of the tissues. To improve their operation and to prove their hypothesis, they performed subperiosteal augmentation rhinoplasty in 22 patients with satisfactory results. At the same time, they investigated the biomechanical properties of human nasal periosteum and fascia, including tensile strength, the stress-strain relationship, and stress relaxation characteristics under uniaxial tension. Although it has less failure strain, the periosteum has more tensile strength than fascia. So, in the view of biomechanics, the periosteum is thicker, tougher, and stiffer than fascia, and thus more suitable for covering silicone implants.
在过去6年里，作者们对406例患者进行了经典硅胶隆鼻术。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。他们提出，大多数并发症与植入物的深度和组织特性有关。为了改进手术方法并验证他们的假设，他们对22例患者进行了骨膜下隆鼻术，结果令人满意。同时，他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。虽然骨膜的破坏应变较小，但它比筋膜具有更大的拉伸强度。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。
