To explore the feasibility of one-stage repair of hypospadias using the meatal-based flap overlapping with buccal mucosal graft.
From March 2002 to May 2004, 21 patients with hypospadias were treated with the meatal-based flap overlapping with buccal mucosal graft. Their ages ranged from 14 months to 8 years. The procedure were as follows: urethral plate at proximal corona was cut to correct glandular tilt and chordee; the buccal mucosa taking from inner cheek was then fixed on tunica albuginea of ventral shaft with suture; and the meatal-based flap was rotated distally and overlaid with buccal mucosal graft to repair urethra.
All patients were followed up 3-18 months (7 months on average). A cosmetic glans and a vertically oriented, normal appearing slit meatus were achieved. Two patients had fistulas on lateral corona. Fistula spontaneously healed in 1 case and the other one was repaired after 6 months.
The technique of meatal-based flap overlapping with buccal mucosal graft can completely correct glandular tilt and chordee, prove good cosmetic and functional glans and meatus.
探讨采用尿道口基底部皮瓣与颊黏膜移植片重叠术一期修复尿道下裂的可行性。
2002年3月至2004年5月，对21例尿道下裂患者采用尿道口基底部皮瓣与颊黏膜移植片重叠术进行治疗。患者年龄为14个月至8岁。手术步骤如下：在冠状沟近端切断尿道板以纠正阴茎头倾斜和阴茎下弯；然后将取自颊内侧的颊黏膜用缝线固定于阴茎腹侧白膜；将尿道口基底部皮瓣向远端旋转并与颊黏膜移植片重叠以修复尿道。
所有患者均获随访3 - 18个月（平均7个月）。阴茎头外形美观，尿道口呈纵向、外观正常的裂隙状。2例患者冠状沟外侧出现瘘管。1例瘘管自行愈合，另1例在6个月后修复。
尿道口基底部皮瓣与颊黏膜移植片重叠术可完全纠正阴茎头倾斜和阴茎下弯，使阴茎头和尿道口获得良好的外形及功能。
