The use of lingual mucosal graft in adult anterior urethroplasty: Surgical steps and short-term outcome

Objectives: Investigate the tolerability, safety, and efficacy of using the lingual mucosal graft (LMG) for anterior urethroplasty. Methods: Ten patients (average age, 41 yr) under-went substitution urethroplasty LMG. Harvesting the graft from the tongue was performed by either the oral surgeon or the urologist. In five patients with penile urethral strictures, the grafts were placed on the dorsal urethral surface as a "dorsal inlay." In five patients with bulbar urethral strictures, the grafts were used as a "dorsal inlay" (3 cases) or "ventral onlay" (2 cases). The average follow-up was 5 mo (range: 3-12 mo). Results. Nine cases (90%) were successful and one (10%) was a failure. Three patients who underwent bulbar urethroplasty showed prior failed repair using buccal mucosal grafts harvested from a single cheek (I case), from both cheeks (1 case), or from the lip (1 case). The length of the lingual grafts was 4-6 cm (mean: 4.5 cm) with a width of 2.5 cm. No patient developed early or late postoperative complications on the harvest site related to the tongue surgery. No difference was observed in patients in whom the graft harvesting was performed by the oral surgeon compared to the patients in whom the procedure was performed by the urologist. Conclusions: The surgical technique for harvesting a graft from the tongue is simple and safe. The tongue may be the best alternative donor site to the lip when a thin graft is required for urethroplasty or when the cheek harvesting is not possible. (C) 2007 European Association of Urology.
