Narrow palpebral fissures, short lower lids, and full cheeks are hallmarks of youthful periorbita. The presence of these features is predicated on a convex upper midface skeleton. Faces whose midface skeletons are flat or concave do not manifest these youthful attributes, tend to age prematurely, and are prone to lower lid malposition after blepharoplasty.
Augmentation of the infraorbital rim with alloplastic implants can provide convexity to the deficient upper midface skeleton. Suspension of the cheek soft tissues (subperiosteal midface lift) on this now supportive framework narrows the palpebral fissure, shortens the lower lid, and gives fullness to the cheek. The addition of lateral canthopexy to skeletal augmentation and subperiosteal midface lift can restore lower lid position when previous blepharoplasty has resulted in lower lid malposition in patients with deficient midface skeletons.
This concept has been utilized in 87 patients (65 female, 22 male) over the last 7 years. Of these 87 patients, four patients (5 percent) required revision surgery to correct implant malposition or prominence. Three patients (3 percent) required implant removal to treat infection. Implants were later replaced in two of these three patients.
Augmentation of the infraorbital rim with alloplastic implants provides convexity to the upper midface skeleton. Together with lower lid and midface soft-tissue suspension, it creates or restores youthful periorbital aesthetics.
狭窄的睑裂、短的下睑和丰满的脸颊是年轻眶周的特征。这些特征的存在取决于凸面的中面部骨骼。中面部骨骼平坦或凹陷的脸不会表现出这些年轻的特征,往往会过早衰老,并在眼睑成形术后容易出现下睑位置不正。
用异体植入物增强眶下嵴可以为凹陷的中面部骨骼提供凸度。将颊部软组织(骨膜下中面部提升)悬挂在这个支撑框架上,可以缩小睑裂,缩短下睑,并使脸颊丰满。在中面部骨骼增强和骨膜下中面部提升的基础上增加外侧眦固定术,可以在先前的眼睑成形术导致中面部骨骼凹陷的患者中出现下睑位置不正时,恢复下睑位置。
在过去的 7 年中,这一概念已在 87 名患者(65 名女性,22 名男性)中得到应用。在这 87 名患者中,有 4 名(5%)需要进行修复手术以纠正植入物位置不正或突出。有 3 名(3%)需要取出植入物以治疗感染。在这 3 名患者中的 2 名后来更换了植入物。
用异体植入物增强眶下嵴为中面部骨骼提供凸度。与下睑和中面部软组织悬吊术一起,它可以创造或恢复年轻的眶周美学。
