Insights
Pediatric craniofacial surgery using small plating systems presents unique challenges. Surgeons must be aware of potential plate displacement, isolation, and incorrect placement due to infant skull growth.
Area of Science:
- Craniofacial surgery
- Pediatric orthopedics
- Biomedical engineering
Background:
- Smaller plating systems are increasingly used in pediatric craniofacial procedures.
- Infant and child skull anatomy presents unique challenges for surgical implants.
- Previous literature has not fully addressed complications specific to pediatric plating.
Purpose of the Study:
- To identify and classify previously undescribed problems associated with plating systems in infants and children.
- To investigate the mechanisms behind observed complications.
- To inform surgical best practices for pediatric craniofacial reconstruction.
Main Methods:
- Retrospective review of pediatric craniofacial cases utilizing plating systems.
- Classification of observed complications into distinct categories.
- Analysis of skull growth patterns and their potential impact on implant stability.
Main Results:
- Identified three primary complication categories: plate displacement, plate and screw isolation, and incorrect plate placement.
- Observed plate displacement where implants migrate inward with skull growth, potentially breaching the dura.
- Documented instances of bone resorption leading to plate and screw isolation, and challenging reoperations due to initial inner cortex placement.
Conclusions:
- Pediatric skull growth dynamics can lead to unique complications with plating systems.
- Plate displacement, isolation, and malplacement pose risks in infant craniofacial surgery.
- Understanding bony resorption and deposition models is crucial for preventing adverse outcomes.
Abstract:
With the introduction of smaller plating systems, many surgeons have adopted their use for craniofacial procedures in infants and small children. We have encountered some previously undescribed problems associated with the use of plates and screws in infants and children. These problems can be classified into three general areas: 1) Plate displacement. This occurs after placement of the metal plates on the outside of the infant calvaria. With subsequent growth, these plates and screws may be found along the inner cortex of the skull with screw points embedded through dura. 2) Plate and screw isolation. In certain locations in young children, plates placed on the outer cortex of bone may later be found to be more prominent, isolated on a peninsula of bone. 3) Plate placement. We have also encountered plates that have been placed along the inner cortex of the skull during a previous operative procedure. This makes subsequent surgery extremely difficult and may increase the risk for secondary surgery. We propose that a previously described model for growth, involving areas of bony resorption and deposition, may be responsible for the observed plate displacement.
