RATIONALE
Titanium mesh is one of the most widely used implant materials applied in cranioplasty; however, it has been reported to encounter the risk of progressive scalp thinning and implant exposure over time. Here we present 2 cases of exposed titanium mesh (TM) and unusual phenomena of full-thickness skin regeneration beneath the mesh.
PATIENT CONCERNS
Two patients, 1 with an 8-year and 1 with a 2-year history of implant exposure after cranial TM implantation.
DIAGNOSES
The patients were diagnosed with scalp ulcers and cranial TM exposure.
INTERVENTION
The exposed part of the implant was removed, and the full-thickness skin beneath the mesh was directly used as functional soft tissue coverage to repair the scalp defect.
OUTCOMES
Full recovery for both patients with cosmetic satisfaction.
LESSONS
Though the exact mechanism of this epithelisation phenomenon beneath the TM remains to be elucidated, it provided a feasible choice for clinicians to reconstruct the scalp's integrity without exerting complicated procedures when dealing with similar cases.
背景
钛网是颅骨修补术中应用最广泛的植入物材料之一；然而，据报道，随着时间的推移，它存在头皮逐渐变薄和植入物暴露的风险。在此，我们介绍了 2 例钛网（TM）暴露和网下全层皮肤再生的异常现象。
病例介绍
2 例患者，1 例颅骨 TM 植入后 8 年，1 例 2 年出现植入物暴露。
诊断
患者均被诊断为头皮溃疡和颅骨 TM 暴露。
干预措施
切除暴露的植入物部分，直接使用网下全层皮肤作为功能性软组织覆盖物修复头皮缺损。
结果
2 例患者均完全康复，美容满意度高。
结论
尽管 TM 下这种上皮化现象的确切机制仍有待阐明，但当遇到类似病例时，它为临床医生提供了一种可行的选择，可以在不进行复杂手术的情况下重建头皮的完整性。
