The correction of infraorbital volume loss with dermal fillers results in a natural, youthful, rested appearance. Defects in this facial region should be treated for optimal patient satisfaction.
This retrospective review describes large-scale use of injection of calcium hydroxylapatite (CaHA) and a technique for injection into the infraorbital region.
Using a 30-gauge, 0.5 needle, CaHA was injected into the infraorbital region of 301 patients. Neat CaHA was initially twice diluted with lidocaine 2% solution in 85 patients. Subsequently, 216 patients were treated with single-dilution CaHA and 0.15 mL of 2% lidocaine.
Injection of CaHa through a 30-gauge, 0.5 needle resulted in minimal bruising, discomfort, or pain. Infraorbital volume restoration was achieved efficiently and effectively, with natural results. Patients were satisfied with the longevity of correction. Adverse events were few and confined to ecchymosis (10%), edema (2%), and erythema (1%). Three of six patients reported edema lasting beyond 7 days. No overcorrection was observed.
Using a 30-gauge, 0.5 needle, diluted CaHA can be safely injected into the infraorbital region with minimal adverse events and high patient satisfaction.
使用真皮填充剂矫正眶下容积缺失可带来自然、年轻、容光焕发的外观。为了让患者获得最佳满意度，该面部区域的缺陷应得到治疗。
本回顾性研究描述了羟基磷灰石钙（CaHA）注射的大规模应用以及一种眶下区域注射技术。
使用30G、0.5英寸的针头，将CaHA注射到301例患者的眶下区域。最初，85例患者将纯CaHA用2%利多卡因溶液进行了两次稀释。随后，216例患者接受了单次稀释的CaHA和0.15 mL 2%利多卡因的治疗。
通过30G、0.5英寸的针头注射CaHA导致的瘀伤、不适或疼痛最小。眶下容积得到了有效恢复，效果自然。患者对矫正效果的持久性感到满意。不良事件较少，仅限于瘀斑（10%）、水肿（2%）和红斑（1%）。6例患者中有3例报告水肿持续超过7天。未观察到过度矫正。
使用30G、0.5英寸的针头，稀释后的CaHA可以安全地注射到眶下区域，不良事件最少，患者满意度高。
