Complications of PMMA Injection for Penile Enlargement

Polymethylmethacrylate (PMMA) injections have been increasingly used by plastic surgeons and dermatologists for cosmetic soft tissue augmentation and facial rejuvenation. Today, PMMA products are the most widely used dermal fillers. These injections are also used to achieve penis enlargement. An injection of silicone into the penis and scrotum is used to gain girth. However, this method is associated with many complications.

PMMA Penile Augmentation Procedures Side Effects

PMMA penile augmentation procedures are associated with several complications, including pain, bleeding, swelling, infection, and hematoma.

Risks and complications associated with PMMA penile enlargement procedures are based on injecting:

  • Free gel in the pocket between the penile shaft and its skin
  • Several micro beads in the pocket

The aforementioned mechanisms are associated with a number of side effects, including:

  • Uneven penile shape after injection
  • Uneven absorption of the permanent floating gel with asymmetries
  • Detachment of the injected material
  • Disproportional spreading of the injected content
  • Unpredictable areas of absorption causing deformed and disproportionate penile shape
  • Buildup of lumps and bumps
  • Acute infection from the foreign material
  • Internal scarring
  • Severe fibrosis
  • Damage to veins and arteries
  • Inflammatory reaction to micro-beads
  • Severe damages to the penile shaft
  • Penile deformity
  • Multiple capsule formation and retraction of soft tissue
  • Severe granuloma formation
  • Chronic penile skin scarring and necrosis
  • Necrotic damage to the penile skin
  • Severe damage to penile erectile tissue, causing curvature and erectile dysfunction
  • Thickening of the penile skin

The extent of damages and complications caused by Polymethylmethacrylate penis augmentation injections are often permanent and hard to treat. It is best to review all the safety guidelines before choosing this procedure of PMMA injection for penile enhancement. Fortunately, complications are rare but if these do occur, they can be severe and impossible to treat.
