Efficacy of a fingertip reconstruction technique using the tongue-shaped flap and advancement flap for repairing congenital syndactyly with osseous fusion of the distal phalanges.

BACKGROUND

To explore the clinical efficacy of using tongue-shaped flaps and advancement flaps to reconstruct the fingertips in congenital syndactyly patients with osseous fusion of the distal phalanges.

METHODS

From January 2016 to January 2019, 12 patients with congenital syndactyly, involving 30 digits in total, presented to our hospital and were surgically treated with tongue-shaped flaps, as well as with advancement flaps to reconstruct the fingertips. The flap infection rate, necrosis rate and any other early complications were recorded. Fingertip aesthetics were reported according to the modified Bulic scale. A questionnaire was used to assess the satisfaction of the patients' family members.

RESULTS

All cases were thoroughly reviewed. The postoperative period for inclusion in this study ranged from 36 to 60 months, with an average follow-up time of 45 months. During this period, no complications such as infection and/or necrosis of any flap were observed. Significant improvements in finger aesthetics and functioning compared to preoperative values were observed in most cases. Based on the modified Bulic scale, of 30 fingertips, an excellent result was obtained for 3, a very good result for 13, a good result for 13 and a poor result for just 1. Family members were satisfied with the treatment outcome.

CONCLUSIONS

This technique employing tongue-shaped flaps and advancement flaps to reconstruct fingertips is effective, which enables the attainment of favourable aesthetic and functional outcomes in congenital syndactyly patients with osseous fusion of the distal phalanges.
