Summary
Radical osteoclastic craniectomy effectively treats sagittal synostosis in infants under six months, yielding optimal skull contours. For older children, alternative osteoplastic procedures are recommended for better outcomes.
Area of Science:
- Neurosurgery
- Pediatric Surgery
- Craniofacial Surgery
Background:
- Sagittal synostosis, a premature fusion of the sagittal suture, leads to abnormal skull shape.
- Surgical intervention is necessary to correct the deformity and allow for brain growth.
Purpose of the Study:
- To evaluate the efficacy of radical osteoclastic craniectomy for sagittal synostosis.
- To determine the optimal age for this surgical procedure based on outcomes.
Main Methods:
- A retrospective review of 60 consecutive patients undergoing radical osteoclastic craniectomy for sagittal synostosis.
- Patients were categorized into three age groups: ≤6 months (Group I), 7–12 months (Group II), and >12 months (Group III).
- Outcomes assessed included reossification time, skull contour, and cosmetic results.
Main Results:
- Optimal skull contour and rapid reossification (within 6 months) were achieved in Group I (≤6 months).
- Prolonged reossification (≥12 months) and partially abnormal contours were observed in Group II (7–12 months).
- Incomplete reossification and persistent pseudosutures occurred in Group III (>12 months), with limited contour improvement.
Conclusions:
- Radical osteoclastic craniectomy is the preferred method for sagittal synostosis in infants up to 6 months, offering the best cosmetic results.
- For older children, osteoplastic morcellation procedures are recommended due to suboptimal outcomes with radical osteoclastic craniectomy.
- The procedure demonstrated reversibility of enlarged frontal subarachnoid spaces across all age groups.
