Objective:
Nonsyndromic multiple-suture synostosis (MSS) is one of the rarest types of craniosynostosis. While both endoscopic and open surgical approaches have demonstrated efficacy for MSS patients, a comprehensive comparison of perioperative outcomes between the two approaches has yet to be fully explored. The aim of this systematic review and meta-analysis was to assess the available evidence among the two surgical approaches to better inform the management of complex craniosynostosis.
Methods:
PubMed, Embase, and Scopus were searched for studies published from the first reports through February 2024 that reported surgical outcomes of either endoscopic or open surgery for nonsyndromic MSS. The main outcome was the reoperation rate, with secondary endpoints including transfusion rates, intraoperative complications, and overall complications, with a subgroup analysis conducted for patients with nonsyndromic bicoronal synostosis.
Results:
Sixteen studies involving 310 patients were analyzed. Patients undergoing open surgery were older than those treated with endoscopy (mean age 10.39 vs 3.21 months). The pooled analysis showed a reoperation rate of 11% (95% CI 4%-23%, I2 = 25%) for endoscopic surgery compared with 22% (95% CI 14%-31%, I2 = 0) for open surgery (p = 0.11). Transfusion rates were 26% (95% CI 13%-45%, I2 = 50%) for endoscopic surgery and 50% (95% CI 22%-78%, I2 = 71%) for open surgery (p = 0.18). Intraoperative complications were similar: 17% (95% CI 7%-34%, I2 = 0%) for endoscopic vs 15% (95% CI 4%-42%, I2 = 76%) for open surgery (p = 0.85). Overall complication rates were 15% (95% CI 7%-31%, I2 = 45%) for endoscopic surgery and 20% (95% CI 9%-38%, I2 = 65%) for open surgery (p = 0.59). In the subgroup analysis of bicoronal synostosis, the reoperation rate was 10% (95% CI 4%-21%, I2 = 0%) for endoscopic surgery versus 16% (95% CI 7%-32%, I2 = 0%) for open surgery (p = 0.39).
Conclusions:
While both surgical approaches are reasonable options for nonsyndromic MSS, this meta-analysis suggests that endoscopic surgery could be associated with lower morbidity when compared with open surgery. Future studies with longer follow-up periods will be needed to validate these findings and contribute to the understanding of complex craniosynostosis management.
