This study aimed to demonstrate the expanding versatility of keystone flap reconstruction in fingertips. Fifteen patients who underwent the modified mini-keystone flap reconstruction for tiny volar pulp defects of the fingertip between September 2020 and February 2021 were included in this study (average age: 43.4 ± 13.52 years, range: 19-61 years). Patient data were retrospectively collected from their medical records. The two-point discrimination test was used to evaluate the degree of sensory recovery. All defects were successfully covered with the modified mini-keystone flap. The defect sizes ranged from 0.5 cm × 1 cm to 1.2 cm × 2.0 cm, and the flap sizes ranged from 0.7 cm × 1.5 cm to 1.5 cm × 3.0 cm. Although one patient showed a small distal margin maceration, all flaps survived fully. The overall outcomes were favorable at the mean follow-up period of 5.73 ± 0.79 months. We suggest that the modified mini-keystone flap technique is a promising alternative modality for covering tiny volar pulp defects of the fingertip, with few complications and favorable outcomes.
本研究旨在证明关键皮瓣重建术在指尖部位应用的多功能性不断扩展。本研究纳入了2020年9月至2021年2月期间因指尖掌侧微小软组织缺损而接受改良微型关键皮瓣重建术的15例患者（平均年龄：43.4±13.52岁，范围：19 - 61岁）。从他们的病历中回顾性收集患者数据。采用两点辨别试验评估感觉恢复程度。所有缺损均成功采用改良微型关键皮瓣覆盖。缺损大小范围为0.5 cm×1 cm至1.2 cm×2.0 cm，皮瓣大小范围为0.7 cm×1.5 cm至1.5 cm×3.0 cm。尽管有1例患者出现远端边缘轻度浸渍，但所有皮瓣均完全存活。在平均5.73±0.79个月的随访期内，总体结果良好。我们认为改良微型关键皮瓣技术是覆盖指尖掌侧微小软组织缺损的一种有前景的替代方法，并发症少且效果良好。
