As nonsurgical rejuvenation with fillers continues to grow in popularity, patients are increasingly interested in more durable results. Polymethylmethacrylate (PMMA)-collagen gel is unique among fillers in that the PMMA microspheres are not completely absorbed and phagocytosed by the body. This durability coupled with the biophysical properties of PMMA makes it a poor choice for periorbital rejuvenation, an unforgiving and highly complex anatomic area.
Between 2011 and 2018, 14 patients with PMMA granulomas in various facial areas self-referred to the senior author's practice. Of these patients, 11 were managed nonsurgically; however, all 3 patients who presented with granulomas in the infraorbital area required surgery to remove the filler and restore a natural aesthetic.
The 3 patients with significant swelling and PMMA filler nodules in the infraorbital area with unacceptable cosmetic appearance were females between the ages of 50 and 55 years. Nonsurgical protocols were unsuccessful, and surgical removal was required. All subjects have been followed for a minimum of 2 years with no immediate- or long-term postoperative complications secondary to PMMA removal. Patients remain satisfied with the outcome of the surgery.
Despite the evidence that the periorbital area is prone to adverse events when injected with particulate fillers, misguided enthusiasm for PMMA-collagen gel as a durable treatment continues to lead to unnecessary and severe complications in patients. The case studies presented here highlight that this product should not be introduced into the periorbital area. We also describe a surgical treatment approach for its removal if complications arise.
随着非手术填充剂的年轻化治疗越来越受欢迎,患者对更持久的效果越来越感兴趣。聚甲基丙烯酸甲酯(PMMA)-胶原凝胶在填充剂中是独一无二的,因为 PMMA 微球不会被身体完全吸收和吞噬。这种持久性加上 PMMA 的生物物理特性,使得它不适合眶周年轻化治疗,眶周是一个不可原谅且高度复杂的解剖区域。
在 2011 年至 2018 年间,14 名患有不同面部区域 PMMA 肉芽肿的患者自行向资深作者的诊所就诊。这些患者中,有 11 例接受了非手术治疗;然而,所有 3 例眶下区域出现肉芽肿的患者都需要手术切除填充物并恢复自然美学。
3 名女性患者年龄在 50 至 55 岁之间,眶下区域肿胀明显,有 PMMA 填充结节,外观无法接受。非手术方案均无效,需要手术切除。所有患者均随访至少 2 年,由于 PMMA 去除,无即刻或长期术后并发症。患者对手术结果仍然满意。
尽管有证据表明眶周区域注射颗粒状填充物容易发生不良事件,但将 PMMA-胶原凝胶作为一种持久的治疗方法的错误热情仍会导致患者出现不必要且严重的并发症。这里提出的病例研究强调,不应将该产品引入眶周区域。如果出现并发症,我们还描述了一种手术治疗方法来去除它。
