The microscopic minimally invasive approach is effective for sagittal and lambdoidal craniosynostosis. However, it shows a high complication rate in unicoronal and metopic craniosynostosis, making it unsuitable for these conditions.
Area of Science:
- Neurosurgery
- Pediatric Surgery
- Craniofacial Surgery
Background:
- Nonsyndromic craniosynostosis involves premature fusion of skull sutures.
- Minimally invasive techniques are increasingly explored for craniofacial reconstruction.
- Long-term outcome data for microscopic minimally invasive surgery (MIMVS) in craniosynostosis are limited.
Purpose of the Study:
- To evaluate the long-term outcomes of the microscopic minimally invasive approach versus the open approach for treating nonsyndromic craniosynostosis.
- To compare complication rates and reoperation needs between the two surgical techniques.
- To determine the suitability of MIMVS for different types of nonsyndromic craniosynostosis.
Main Methods:
- Retrospective study of 180 consecutive patients with nonsyndromic craniosynostosis treated over 10 years.
- Comparison between 67 patients treated with MIMVS and 113 patients treated with open surgery.
- Analysis of intraoperative and postoperative complications, including reoperation rates.
Main Results:
- Overall complication rates were not significantly different between MIMVS and open approaches (14.9% vs. 7.1%).
- MIMVS in unicoronal craniosynostosis showed a significantly higher complication rate (58.3%) compared to the open approach.
- MIMVS was associated with a higher rate of major reoperations in unicoronal and metopic cases.
Conclusions:
- The microscopic minimally invasive approach is a suitable treatment for nonsyndromic sagittal and lambdoidal craniosynostosis.
- Due to high complication rates, MIMVS is no longer recommended for unicoronal or metopic craniosynostosis.
- Surgical approach selection should be tailored to the specific type of nonsyndromic craniosynostosis.
