To investigate the procedures and effectiveness of platysma scar flap for reconstructing mentocervical appearance in patients with mentocervical cicatricial contracture deformity.
Between April 2004 and August 2011, 26 patients with mentocervical cicatricial contracture deformities were admitted. There were 15 males and 11 females, aged 12-31 years (mean, 18 years). The causes included scald injury in 19 cases and flame injury in 7 cases, including 23 cases of deep second degree burn and 3 cases of third degree burn. The time between injury and scar formation was 6-27 months (mean, 10 months). The mentocervical angle was (117.10 +/- 14.46) degrees, and the cervicomental angle was (143.38 +/- 15.68) degrees. The platysma scar flap transfer (8 cm x 7 cm to 10 cm x 8 cm in size) and skin grafting were performed to reconstruct mentocervical appearance.
The flap and skin graft all survived and the incisions healed by first intention. All the patients were followed up 6 months-3 years (mean, 16 months). The mentocervical and cervicomental angles were significantly reduced to (89.31 +/- 6.30) degrees and (117.83 +/- 10.65) degrees respectively at 2 weeks after operation (P < 0.05), showing no significant difference when compared with normal mentocervical angle (90 degrees) and cervicomental angle (120 degrees) (P > 0.05). The satisfactory results of the mentocervical appearance and cervical extension function were obtained in 21 patients whose mentocervical and cervicomental angles were restored to normal.
Platysma scar flap transfer is an effective method to reconstruct mentocervical appearance and reduce mentocervical and cervicomental angles in patients with mentocervical cicatricial contracture deformity.
探讨颈阔肌瘢痕瓣修复颏颈瘢痕挛缩畸形患者颏颈外观的手术方法及效果。
2004年4月至2011年8月收治26例颏颈瘢痕挛缩畸形患者，男15例，女11例，年龄12～31岁，平均18岁。病因包括烫伤19例，火焰烧伤7例，其中深Ⅱ度烧伤23例，Ⅲ度烧伤3例。受伤至瘢痕形成时间为6～27个月，平均10个月。颏颈角为（117.10±14.46）°，颈颏角为（143.38±15.68）°。采用颈阔肌瘢痕瓣转移（大小为8 cm×7 cm至10 cm×8 cm）及植皮修复颏颈外观。
皮瓣及植皮全部成活，切口一期愈合。所有患者随访6个月至3年，平均16个月。术后2周时颏颈角及颈颏角分别显著减小至（89.31±6.30）°和（117.83±10.65）°（P<0.05），与正常颏颈角（90°）和颈颏角（120°）比较差异无统计学意义（P>0.05）。21例患者颏颈角及颈颏角恢复正常，颏颈外观及颈部伸展功能恢复满意。
颈阔肌瘢痕瓣转移是修复颏颈瘢痕挛缩畸形患者颏颈外观、减小颏颈角及颈颏角的有效方法。
