Surgical techniques to correct scaphocephaly often rely on the implantation of foreign material and/or postoperative helmet therapy and possibly result in minimal correction of frontal bossing. Moreover, foreign material and helmet therapy are associated with extra medical care and financial costs. Frontal bossing is perceived as a prominent, disfiguring feature of scaphocephaly. Herein, authors present the results of a total cranial vault remodeling technique that corrects scaphocephaly features without relying on foreign material or postoperative helmet therapy. It includes frontal release and pterional decompression, which aim to correct frontal bossing.
All patients who had been operated on for isolated scaphocephaly at a single institution between January 2011 and December 2020 were included in this retrospective review. Operation time, transfusion volume, hospital stay, complications, cephalic index (CI), and bossing angle (BA) were analyzed.
Sixty-five patients with nonsyndromic scaphocephaly were included in this analysis. Imaging to calculate the CI and BA preoperatively, immediately postoperatively, and 1 year postoperatively was available in 22 and 20 patients, respectively. The mean CI increased from 69.2% preoperatively to 74.6% postoperatively and 75.5% 1 year postoperatively. The mean BA decreased from 114.5° preoperatively to 111.6° postoperatively and 108.9° 1 year postoperatively. The mean operating time was 2 hours 4 minutes, and the median blood transfusion volume was 100 ml. There were no major complications or reoperations.
The described total cranial vault remodeling technique is a safe procedure that mitigates total treatment burden, as no helmet therapy or implantation of foreign material is needed. It is effective in correcting CI and results in significant frontal bossing correction. The latter is attributed to a distinctive feature of the technique: frontal release and pterional decompression.
