Insights
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.
Abstract:
We report our experience in the surgical treatment of sagittal synostosis using radical osteoclastic craniectomy in 60 consecutive patients. After surgery in children aged 6 months or younger (Group I), reossification usually started 2 weeks postoperatively and was complete within 6 months, resulting in an optimal skull contour. In children aged 7 to 12 months (Group II), reossification was prolonged and lasted for 12 months or longer. The skull contour normalized in its biparietal width and improved in sagittal diameter, remaining, however, slightly abnormal. In children older than 12 months (Group III), the skull contour partly improved in the biparietal diameter but did not change in the sagittal direction. Reossification was incomplete with persistent pseudosutures. Enlarged frontal subarachnoid spaces were reversible or improved in all patients independent of age at the time of surgery. We encountered no complications in our series. In our opinion, radical osteoclastic craniectomy is the simplest, most efficient, and most physiologically sound method for the treatment of sagittal synostosis in patients up to 6 months of age. This procedure allows the rapidly growing brain to form its skull vault, thus providing optimal cosmetic results. In older children, osteoplastic morcellation procedures should be the treatment of choice.
