Use of bioabsorbable plates for cranial fixation.
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.
