LactoSorb fixation plates are made of a bioabsorbable polymer (82% poly-L-lactic acid and 18% polyglycolic acid), and the strength is not inferior to titanium plates. LactoSorb has been used in the fields of pediatric neurosurgery and facial plastic surgery. Cranial fixation in craniotomy is mostly performed using titanium plates and clamps, but there are issues with esthetics and artifacts on postoperative radiographic images. Absorbable plates solve these problems, but are slightly thicker and more expensive. Here, we describe a technique to solve these disadvantages by inserting absorbable plates into the diploe. The present method was employed in 46 patients, and esthetically favorable results were obtained without intraoperative and postoperative complications. Absorbable plates may replace titanium plates as the main device for cranial fixation. The present method is particularly useful for cranial fixation in adults with a thin scalp.
LactoSorb固定板由生物可吸收聚合物制成（82%聚-L-乳酸和18%聚乙醇酸），其强度不低于钛板。LactoSorb已应用于小儿神经外科和面部整形手术领域。开颅手术中的颅骨固定大多使用钛板和夹子，但存在美学问题以及术后影像学图像上的伪影。可吸收板解决了这些问题，但稍厚且更昂贵。在此，我们描述一种通过将可吸收板插入板障来解决这些缺点的技术。本方法应用于46例患者，获得了美观的效果，且无术中及术后并发症。可吸收板可能会取代钛板成为颅骨固定的主要装置。本方法对于头皮薄的成人颅骨固定特别有用。
