本研究的目的是比较单切口（单切口，改良单切口）和活板门手术技术从腭上皮下结缔组织移植物的伤口愈合和患者疼痛感。选择36例患者进行上皮下结缔组织移植物根面覆盖手术，并随机分配到两个单切口组或活板门组（n = 12/组）。手术后一周，记录修改后的早期伤口愈合指数（EHI）、患者疼痛和止痛药摄入量。随访至完全上皮化，单切口技术较活板门法明显改善早期愈合。具体而言，单切口技术的平均EHI为2.50 +/- 1.14，而活板门技术为3.33 +/- 1.30。单切口组的继发性愈合发生率显著较低。同时，与活板门组相比，止痛药摄入的累积剂量和持续时间显著减少。在本试验范围内，单切口技术可以改善上皮下结缔组织移植物采集后的早期愈合，并减少患者疼痛。避免活板门切口采集结缔组织移植物可能会降低患者发病率。
The aim of this study is to compare wound healing and patient pain perception of single-incision (single-incision, modified single-incision) and trap-door surgical techniques to harvest subepithelial connective tissue grafts from the palate.Thirty-six patients were selected for root coverage procedures with subepithelial connective tissue grafts and randomly assigned to two single-incision groups or a trap-door group (n = 12/group). One week after surgery, a modified early-wound healing index (EHI), patient pain and painkiller intake were recorded. Follow-up was performed until complete epithelialization was achieved.Single-incision techniques showed significantly improved early healing over trap-door approaches. Specifically, the mean EHI was 2.50 +/- 1.14 for single-incision techniques, as compared to 3.33 +/- 1.30 for trap door. The incidence of secondary healing was significantly lower in the single-incision groups. Concomitantly, the cumulative dosage and duration of painkiller intake were significantly reduced, as compared to the trap-door group.Within the limits of this trial, single-incision techniques can lead to improved early healing and reduced patient pain after subepithelial connective tissue graft harvesting than trap-door techniques.Avoiding trap-door incisions for harvesting of connective tissue grafts may reduce patient morbidity.
