I am often consulted by patients regarding early skull repair surgery, which is highly recommended by some physicians. Personally, I think that early cranial repair surgery should not be promoted for the time being, and there is still a big difference of opinion in the international academic community on this issue. Early skull repair surgery refers to skull repair surgery within 2 months or even 1 month after craniotomy. Although some studies have shown that there is no difference in postoperative complication rates and infection rates between early and late cranioplasty. For example, a 2011 article published in NEUROSURGERY by Dr. Sanjay Yadla of Thomas Jefferson University suggests that there is no difference in infection rates between early (<3 months) and late (>3 months) cranial repair after craniotomy. However, several relevant regression studies published internationally have recently discouraged early (<2 months) cranial repair. For example, a study published in April 2012 in the journal JOURNAL OF NEUROTRAUMA by Dr. Patrick Schuss of the University of Frankfurt (Johann Wolfgang Goethe-University), Germany, showed that the complication rate for early cranial repair (<2 months) was significantly higher than that for late cranial repair (>2 months). cranial repair surgery (>2 months). For example, a study by Dr. Brian Ragel of Oregon Health & Science University, published in January 2013 in J Neurosurg, showed that cranial repair surgery performed early (<10 weeks, about 2.5 months) after a craniotomy for cerebrovascular accident had a significantly higher complication rate than cranial repair surgery performed late (<2 months). The complication rate was significantly higher in patients who underwent cranial debridement for cerebrovascular accidents early (<10 weeks, about 2.5 months) than in those who underwent cranial repair late (>10 weeks). In my personal opinion, I tend to follow the conventional practice of performing cranial repair 3-6 months after craniotomy, depending on the patient’s condition.
