An unknown percentage of men will take every risk to develop a larger penis. Thus far, most injectables have caused serious problems. Polymethylmethacrylate (PMMA) microspheres have been injected as a wrinkle filler and volumizer with increasing safety since 1989.
To report on a safe and permanently effective method to enhance penile girth and length with an approved dermal filler (ie, PMMA).
Since 2007, the senior author has performed penile augmentation in 752 men mainly with Metacrill, a suspension of PMMA microspheres in carboxymethyl-cellulose.
The data of 729 patients and 203 completed questionnaires were evaluated statistically.
The overall satisfaction rate was 8.7 on a scale of 1 to 10. After one to three injection sessions, average girth increased by 3.5 cm, or 134% (10.2 to 13.7 cm = 134.31%). Penile length also increased by weight and stretching force of the implant from an average of 9.8 to 10.5 cm. Approximately half the patients perceived some irregularities of the implant, which caused no problems. Complications occurred in 0.4%, when PMMA nodules had to be surgically removed in three of the 24% of patients who had a non-circumcised penis.
After 5 years of development, penile augmentation with PMMA microspheres appears to be a natural, safe, and permanently effective method. The only complication of nodule formation and other irregularities can be overcome by an improved injection technique and better postimplantation care.
有未知比例的男性会不惜一切风险来增大阴茎尺寸。到目前为止，大多数注射剂都引发了严重问题。自1989年以来，聚甲基丙烯酸甲酯（PMMA）微球作为一种皱纹填充剂和容积增大剂进行注射，安全性不断提高。
报告一种使用已获批准的真皮填充剂（即PMMA）来增加阴茎周长和长度的安全且永久有效的方法。
自2007年以来，资深作者主要使用Metacrill（一种PMMA微球悬浮于羧甲基纤维素中的制剂）为752名男性实施阴茎增大手术。
对729例患者的数据和203份完整问卷进行统计学评估。
总体满意度在1至10分的量表上为8.7分。经过一至三次注射疗程后，平均周长增加了3.5厘米，即134%（从10.2厘米增至13.7厘米 = 134.31%）。阴茎长度也因植入物的重量和拉伸力从平均9.8厘米增加到了10.5厘米。约一半患者察觉到植入物存在一些不平整，但未引发问题。并发症发生率为0.4%，在24%未行包皮环切术的患者中有3例需通过手术切除PMMA结节。
经过5年的发展，使用PMMA微球进行阴茎增大似乎是一种自然、安全且永久有效的方法。通过改进注射技术和加强植入后护理，可以克服结节形成及其他不平整等唯一并发症。
