Abstract

Background: To review the cases of dangling-type thumb polydactyly treated with suture ligation vs surgical excision. Methods: Cases of dangling-type thumb polydactyly treated in 2 different hospitals from 1994 to 2014 were recruited. Group 1 includes cases treated with suture ligation in hospital 1; Group 2 includes cases treated with surgical excision in hospital 2. The demographics data, early clinical outcomes and early complications were retrieved from clinical notes. All cases were contacted for a final assessment. Results: There were 23 cases recruited in group 1 and 26 cases recruited in group 2. The mean age at the time of procedure was 15.9 days (group 1) vs. 14 months (group 2). The infection rate was comparable in both groups (4.35% vs. 3.85%). 12 cases in group 1 and 14 cases in group 2 completed a final assessment. Residual tissue is common in group 1 (58.5%) and 4 cases (33.3%) required revision surgery. No case in group 2 had residual tissue and none require revision surgery. There was no painful neuroma in both groups and all patients achieved normal thumb and hand functions. The parental satisfaction score was 7.8 (group 1) and 8.8 (group 2) with no statistical difference (p = 0.061). Conclusions: Suture ligation and surgical excision are safe and effective treatment options for dangling-type thumb polydactyly. Both methods received comparable parental satisfaction. However, residual tissue is common after suture ligation while this problem is not observed after surgical excision.
