Linear craniectomy for early posterior decompression in craniosynostoses: technique and results

Area of Science:

• Pediatric Neurosurgery
• Craniofacial Surgery
• Congenital Abnormalities

Background:

• Complex multisuture synostosis, particularly involving the lambdoid suture, often requires early intervention in infants.
• Literature on the surgical technique and outcomes of posterior linear craniectomy (PLC) for these conditions is limited.

Purpose of the Study:

• To detail the surgical technique for posterior linear craniectomy (PLC) in infants with complex multisuture synostosis.
• To identify potential pitfalls and strategies for complication avoidance.
• To review outcomes and long-term results of PLC in this patient population.

Main Methods:

• Retrospective review of seven infants undergoing PLC for complex multisuture synostosis over a 10-year period.
• Detailed description of the surgical technique employed, including preparation and intraoperative considerations.
• Analysis of patient demographics, surgical outcomes, complications, and need for subsequent procedures.

Main Results:

• Seven infants (5 female, 2 male) with a mean age of 3.19 months underwent PLC.
• One patient experienced mortality due to postoperative cardiac arrest; the remaining six had favorable outcomes with good development and no visual impairment.
• Three patients required secondary cranioplasty, one in conjunction with craniofacial distraction.

Conclusions:

• Posterior linear craniectomy (PLC) serves as a viable salvage procedure for young infants with complex synostosis involving the lambdoid suture.
• Meticulous surgical planning and execution are essential for achieving favorable outcomes.
• A versatile surgical approach is necessary to manage the complexities and potential need for future interventions in these often syndromic cases.
