In the 1940s and 1950s, documented cases of purposeful penile foreign body injections began to make it into scientific literature referred to as “penile paraffinomas.” Their surgical correction is challenging due to the risk of skin necrosis and wound breakdown. Herein we present contemporary surgical outcomes of a large case series of 31 penile paraffinomas. METHODS: Retrospective review of penile paraffinomas managed at a single institution over a 15-year period (2006-2021). Patient demographics, surgical management and functional outcomes were extracted from both paper and electronic medical records. RESULTS: Median age at time of referral was 34 (IQR=10.5). Median age at time of first injection was 30 years (IQR=11.5). The substances injected were silicone (47%), paraffin (25%), mineral oils (22%), and unknown (6%). Most (97%) underwent surgical reconstruction with a median of 2 operations per man (range 1-7) and 66 operations in total. Excision with primary closure was possible in 62% of the operations with circumcision required in 18% (Table 1). Closure was by local tissue flap in 3% but split (5%) or full (5%) thickness skin grafts were sometimes required. Complications occurred in 15% (n=10) with the most common being wound breakdown (n=6) followed by skin necrosis (n=3). Erectile dysfunction and loss of penile sensation were uncommon following surgery (7%, n=2 and 3%, n=1 respectively). Only 7% (n=2) of men expressed dissatisfaction with the overall result of their treatment. CONCLUSIONS: Penile paraffinomas are rare and difficult to treat. Performing repeated staged revision surgery reduces the risk of complications by allowing time for healing between each procedure. Very few men expressed dissatisfaction with their treatment despite their limited follow-up due to the severity of their presenting problem.
