Long-term results of buccal replacement corporoplasty for penile curvatures in Peyronie’s disease
The objective. To evaluate the efficacy of using buccal mucosa as a graft for replacement of the penile tunica albuginea plaque in patients with Peyronie’s disease. Patients and methods. Twelve patients with penile curvature (average age 55.2 ± 6.2 years), preserved erectile function (IIEF scores 11–25), mean angle of deformity from 45 to 120° underwent operative intervention – replacement corporoplasty of the penis with the use of a buccal mucosal patch. Operative interventions were performed by two teams of surgeons. The first team performed scalping of the penile body, mobilization of the neurovascular bundle, incision of a plaque, measurement of the sizes of the tunica albuginea defect- the second team of surgeons harvested the buccal mucosa and prepared the graft. Results. The mean operative time was 108 ± 20 min (70–130 min), mean buccal mucosal harvesting time with subsequent preparation of the graft – 30.4 ± 5.2 min (25–40 min), maximal sizes of the incised patch – to 4 x 5 cm. In all patients straightening of the penile curvature was obtained without shortening its length. Also, improvement of erectile function to IIEF scores 22.9 ± 2.85 was noted. The maximal follow­-up time was to 18 months. Conclusion. The authors have proved the indisputable advantages of the buccal mucosa (extensibility, structure of the mucosal patch (muscular fibers), vast vascular network, thickness of the patch), absence of formation of patch contractures, possibility of replacing large size defects, absence of the need for additional incisions (venous patch).
