Human glans penis augmentation using injectable hyaluronic acid gel

Area of Science:

• Urology
• Plastic Surgery
• Aesthetic Medicine

Background:

• Augmentation phalloplasty remains an unestablished procedure for penile enlargement.
• Current penile girth enhancement utilizes dermofat grafts, with some patients experiencing small glans size post-surgery.
• Patient dissatisfaction with glans size necessitates exploring alternative augmentation methods.

Purpose of the Study:

• To evaluate the efficacy and patient satisfaction of hyaluronic acid gel injections for glans penis augmentation.
• To assess the safety and longevity of hyaluronic acid gel for glans augmentation in two distinct patient groups.

Main Methods:

• 100 patients with subjective small penis (Group I) and 87 patients with small glans after dermofat graft (Group II) received 2 cm³ hyaluronic acid gel injections into the glans penis.
• Glandular diameter changes, visual estimation of size, patient satisfaction, and adverse reactions were assessed at 1 year post-injection.

Main Results:

• Significant increase in maximal glandular circumference observed in both groups (P<0.01) at 1 year.
• Over 50% of injected volume was maintained in 95% (Group I) and 100% (Group II) of patients.
• Postoperative satisfaction rates were 77% (Group I) and 69% (Group II), with no serious adverse reactions reported.

Conclusions:

• Injectable hyaluronic acid gel is a safe and effective material for glans penis augmentation.
• The procedure leads to significant glans enlargement and high patient satisfaction.
• Hyaluronic acid gel offers a viable alternative for addressing glans size concerns in reconstructive and aesthetic urology.
