(413) LINGUAL MUCOSAL GRAFT (LMG) FOR PENILE CURVATURES: OUR INITIAL EXPERIENCE

Penile curvatures (PC) exceeding 60 degrees typically require surgical treatment. Surgical approaches involving plaque incision/excision with grafting are preferred in these cases to avoid penile shortening. Buccal mucosa graft (BMG), particularly Lingual Mucosa Graft (LMG), is not typically emphasized in many review articles, and clinical series remain limited. Our aim was to evaluate our initial cases with LMG in the treatment of PC.

From February 2022 until November 2022, three patients, reporting normal erectile function but with PC exceeding 60 degrees that interfered with sexual function, underwent plaque incision and grafting with LMG. Postoperative erectile function, penile deformity, and postoperative complications were assessed.

Median age was 56 (SD ±14.2) years, with a median angle of deformity of 80° (SD ±15.3). One of the patients had a congenital penile curvature (CPC). Two patients reported Peyronie Disease (PD) with a median time since presentation of 3.5 years (range from 3-4). The mean follow-up was 12 months (range 11-20). No donor site complications were reported. De novo mild erectile dysfunction was reported by one patient, who responded to a low-dose phosphodiesterase type 5 inhibitor. One patient presented seven months after surgery an abnormal growth tissue at the graft site, which did not interfere with sexuality. Recurrent curvature was observed in two patients, with a median of 20 degrees (range 20-45). All patients reported satisfactory intercourse.

Although based on a small series, LMG appears to be a valuable substitute for the tunica albuginea in cases of PC. It is readily available without complications at the donor site. However, a larger number of patients is needed to draw any definitive conclusion related to the elasticity of the graft.
