Successful use of rib grafts for cranioplasty in children.
Numerous materials are available for use in cranioplasty including bone, plastics and metals. Rib grafts as a construct for cranial reconstruction offer several advantages: autologous bone source, a formable platform, low infection, regeneration at the donor site and high fusion rates. Criticism of rib graft cranioplasty includes scarring and pain at the donor site, irregular contour at the graft site and graft reabsorption. Since 1988, we have performed rib autograft cranioplasty on 13 patients. Seven females and 6 males combined for an average age of 6 years (11 months to 20 years) at the time of surgery. The mean follow-up from surgery is 27 months (2-48 months), with 11 subjects having at least 12 months. The commonest reasons for cranial reconstruction were: post-traumatic calvarial defect (n = 4), defect from previous craniotomy (n = 3), "growing" skull fracture (n = 2), and defect from previous encephalocele closure (n = 2). Mean defect size was 41 cm(2) (8-144 cm(2)) and average number of ribs harvested was 1.75 (1-3). Simple rib cranioplasty had a mean time in the operating room of 6 h and 30 min. No donor site complications were noted (pneumothorax, significant post-operative pain) and no post-operative infections were encountered. Excellent cranial contour was achieved in each of the 11 patients followed for a minimum of 12 months. One subject required staged reconstructive procedures owing to the size of the defect.
