(051) Safety of Novel Hyaluronic Acid Dermal Filler Injections for Penile Girth Enhancement

Abstract Introduction Limited data exist regarding safety of penile girth enhancement treatments. Reported options for girth enhancement include injections of autologous fat, liquid silicone, hyaluronic acid (HA), or polymethyl-methacrylate, grafting with dermal fat, porcine dermal acellular matrix, or acellular collagen matrix, and surgical placement of a silicone implant. Objective The purpose of our study was to retrospectively evaluate safety in a cohort of men undergoing penile girth enhancement with HA dermal filler at a single site by reporting on post-procedure complications. Methods We performed a retrospective review of men who underwent penile girth enhancement with HA dermal filler from August 2020 through April 2023. Results 471 men underwent penile girth enhancement with HA dermal filler. Two patients experienced injection site infections related to non-compliance post treatment with infection resolution after completing a course of oral antibiotic. One patient reported urinary tract infection symptoms shortly after HA dermal filler procedure and subsequently underwent additional filler injections without recurrence of urinary symptoms. One patient underwent reversal with hyaluronidase after his initial treatment. Three patients developed granulomas which were completely resolved with a single treatment of hyaluronidase. All three of these patients underwent additional HA injections without granuloma formation. Three patients experienced priapism treated without long term sequelae when intracavernosal injection (ICI) therapy was used for tumescence at time of filler injection. Once ICI was no longer used, no patients reported priapism. No patients reported erectile dysfunction or loss of sensitivity. Conclusions Our study suggests that injection of HA dermal filler may be a safe option for men interested in penile girth enhancement. While rare complications may occur, our research suggests they are easily treatable in the outpatient setting without long term sequelae.
