Penile chordee, with and without hypospadias, is amenable to surgical correction. The Nesbit technique of dorsal plication of the ventral tunica albuginea is effective in correcting most cases of corporal disproportion. A hazard with this approach is the potential inclusion of the dorsal neurovascular bundle, with resultant erectile and sensory dysfunction. We developed a simple technique using the Freer elevator to isolate the neurovascular bundle prior to plication. This ensures that no injury occurs to the neurovascular bundle during plication. Since 1994, 37 boys with chordee have been repaired using this approach. Their ages at the time of operation ranged from 5 months to 28 years (mean 9 months). Following standard degloving of the penis, an incision through Buck's fascia is made lateral and parallel to the neurovascular bundle at the maximum level of the chordee. A similar incision is carried out on the contralateral side. A 4-mm-wide Freer elevator is positioned under Buck's fascia while hugging the tunica albuginea. The Freer elevator slides across the midline to the contralateral side, separating Buck's fascia and underlying layers from the tunica albuginea. Following isolation of the bundle, each corporal body is plicated by creating a longitudinal incision through the tunica albuginea, which then is closed transversely with a 5-0 polydioxanone suture. Buck's fascia subsequently is closed with an absorbable suture following confirmation of chordee correction. No complications have been encountered during a mean follow-up of 21 months (range 5-51 months). No patients have required reoperation for persistent chordee. We developed a technique that elevates the neurovascular bundle prior to plication, thereby ensuring no injury to this structure. We have successfully used this modified Nesbit technique since 1994 and have had no complications. Utilization of the Freer elevator adds an estimated 5 minutes to chordee correction compared to a standard plication lateral to the neurovascular bundles. Although long-term follow-up needs to be performed to confirm any erectile or sensory advantage, this approach should be considered whenever plication is to be performed.
阴茎下弯,无论是否合并尿道下裂,均可通过手术矫正。Nesbit技术通过对腹侧白膜进行背侧折叠,可有效矫正大多数阴茎体不对称的病例。该方法的一个风险是可能会累及背侧神经血管束,导致勃起和感觉功能障碍。我们开发了一种简单的技术,即在折叠前使用Freer剥离子分离神经血管束。这可确保在折叠过程中不会损伤神经血管束。自1994年以来,已有37例阴茎下弯的男孩采用此方法进行修复。他们手术时的年龄从5个月至28岁不等(平均9个月)。按照标准的阴茎脱套操作,在阴茎下弯的最大水平处,于Buck筋膜外侧作一个与神经血管束平行的切口。对侧也进行类似的切口。将一把4毫米宽的Freer剥离子置于Buck筋膜下方并紧贴白膜。Freer剥离子滑过中线至对侧,将Buck筋膜及其下层与白膜分离。分离神经血管束后,通过在白膜上作纵向切口对每个阴茎体进行折叠,然后用5-0聚二氧六环酮缝线横向缝合。确认阴茎下弯矫正后,用可吸收缝线关闭Buck筋膜。在平均21个月(5-51个月)的随访期间未出现并发症。没有患者因持续性阴茎下弯需要再次手术。我们开发的这项技术在折叠前提升神经血管束,从而确保不损伤该结构。自1994年以来,我们成功使用了这种改良的Nesbit技术,且未出现并发症。与在神经血管束外侧进行标准折叠相比,使用Freer剥离子进行阴茎下弯矫正估计会增加5分钟时间。尽管需要进行长期随访以确认在勃起或感觉方面是否有优势,但只要进行折叠操作,就应考虑采用此方法。
