Reshaping of the face with age is a result of volume change and loss of support. It is not well understood which tissues are involved in this process. Recent publications suggest that adult bone growth may have a significant role.
We report a longitudinal cephalometric analysis of midfacial growth in adults to determine the role of bone in facial aging.
The Behrents modification of the Bolton Cephalometric study in patients up to age 83 was reviewed. A trigonometric analysis targeted orbital and anterior maxillary growth.
Facial bone growth is shown to continue throughout adulthood. Anterior descent creates increased bone projection.
The appearance of facial aging is caused by attrition of soft tissue volume and loss of support. The deficiency of maxillary bone projection seen in some patients, with tear trough depression and negative vector eyelid (polar bear), preexists adulthood and is unmasked with age.
面部随年龄增长而重塑是体积变化和支撑力丧失的结果。目前尚不清楚哪些组织参与了这一过程。最近的出版物表明成人骨骼生长可能起重要作用。
我们报告一项针对成年人面中部生长的纵向头影测量分析，以确定骨骼在面部衰老中的作用。
回顾了对83岁及以下患者的博尔顿头影测量研究的贝伦特改良法。三角测量法针对眼眶和上颌前部生长。
研究表明面部骨骼生长在整个成年期持续进行。前部下降导致骨骼投影增加。
面部衰老的外观是由软组织体积的磨损和支撑力的丧失引起的。一些患者出现的上颌骨投影不足，伴有泪沟凹陷和负向量眼睑（“北极熊”征），在成年前就已存在，并随着年龄增长而显现出来。
