We aimed to investigate how the thickness of removed skin grafts affects the healing time at the donor site, with a focus on the depth of the donor wound and the normal thickness of the scalp.
We examined the outcomes of the donor sites of thick split-thickness skin grafts using hairy scalp skin in 102 Korean patients. We measured the thickness of the scalp donor skin using preoperative ultrasonography, histometric thickness of normal scalp skin in 61 patients, and histometric thickness of the thickest part of the grafted skin after surgery.
The mean normal ultrasound thickness of the scalp donors was 1.711 mm, with a mean histometric normal scalp thickness of 1.926 mm (61 cases), mean dermatome depth set of 0.569 mm (22/1000 inches, 22 mils), and mean histometric harvested skin thickness of 0.677 mm. The relationship between healing time and percentage of histometric graft thickness per ultrasonographic normal scalp skin thickness was statistically significant and correlated positively. Healing of the partial portion of the scalp was delayed in 9 donors due to infection and folliculitis. Scalp donor wounds healed during postoperative days 6 and 15, except for the ones with infected portions.
Patients in this study successfully achieved scarless regenerative healing of their scalp donor wounds. Furthermore, adequate wound dressing can prevent alopecia and scarring of infected donor wounds. The results of this study offer valuable insights into the advantages of using scalp skin in grafts, underscoring its potential as a preferred option for achieving optimal regenerative healing.
我们旨在研究移除的皮肤移植片厚度如何影响供皮区的愈合时间，重点关注供皮伤口的深度和头皮的正常厚度。
我们检查了102例韩国患者使用头皮毛发皮肤进行厚中厚皮片移植后的供皮区结果。我们使用术前超声测量头皮供皮的厚度，测量了61例患者正常头皮皮肤的组织学厚度以及术后移植皮肤最厚部分的组织学厚度。
头皮供区的平均正常超声厚度为1.711毫米，正常头皮组织学平均厚度为1.926毫米（61例），平均取皮深度设置为0.569毫米（22/1000英寸，22密耳），平均组织学取皮厚度为0.677毫米。愈合时间与超声测量的正常头皮皮肤厚度中组织学移植片厚度百分比之间的关系具有统计学意义且呈正相关。9个供区因感染和毛囊炎导致头皮部分愈合延迟。除有感染部分的供区外，头皮供皮伤口在术后第6天至第15天愈合。
本研究中的患者成功实现了头皮供皮伤口的无瘢痕再生愈合。此外，适当的伤口敷料可预防感染供皮伤口的脱发和瘢痕形成。本研究结果为在移植中使用头皮皮肤的优势提供了有价值的见解，强调了其作为实现最佳再生愈合的首选方案的潜力。
