A buccal mucosa graft from the lower lip was used for meatal reconstruction in 3 patients. The buccal mucosa graft was combined with a bladder mucosa graft for urethral substitution in 1 adult and 1 child, and was anastomosed to a skin tube for creating a glanular urethra in 1 child. The buccal mucosa graft obtained was approximately twice as wide as the desired urethra. Postoperatively the buccal mucosa graft became shrunken at the proximal anastomosis and urethral stricture developed in 2 children. The graft did not shrink at the meatus, but the meatus became widened in 2 patients. These results suggest that a buccal mucosa graft is useful for meatal reconstruction, but further technical improvement is necessary to avoid postoperative complications.
3例患者采用下唇颊黏膜移植进行尿道口重建。1例成人和1例儿童采用颊黏膜移植联合膀胱黏膜移植进行尿道替代，1例儿童将颊黏膜移植与皮管吻合以构建龟头尿道。获取的颊黏膜移植物宽度约为预期尿道宽度的两倍。术后，2例儿童颊黏膜移植物在近端吻合处出现萎缩并发生尿道狭窄。移植物在尿道口处未萎缩，但2例患者尿道口变宽。这些结果表明，颊黏膜移植可用于尿道口重建，但为避免术后并发症，有必要进一步改进技术。
