Insights
This study compares transcranial and transfacial surgical approaches for frontoethmoidal encephaloceles (FEC). Combining both methods offers safer treatment and improved cosmetic outcomes for pediatric patients.
Area of Science:
- Neurosurgery
- Pediatric Surgery
- Craniofacial Surgery
Background:
- Frontoethmoidal encephaloceles (FEC) present complex challenges in pediatric neurosurgery.
- Treatment aims include safe neurosurgical correction, optimal cosmesis, and minimized surgical trauma.
Purpose of the Study:
- To compare the efficacy and outcomes of transcranial versus transfacial surgical approaches for FEC.
- To determine the optimal surgical strategy for addressing the unique anatomical challenges of FEC.
Main Methods:
- Retrospective review of 6 pediatric patients treated for FEC between 1986 and 1991.
- Comparison of surgical techniques, focusing on exposure, correction of orbital walls, nasal reconstruction, and cosmetic results.
Main Results:
- The transcranial approach provides excellent access for neurosurgical correction and reconstruction of medial orbital walls and nasal dorsum.
- Correction of nasal length remains a significant challenge, where the transfacial approach may offer advantages.
- Combined approaches were utilized to achieve safer treatment and better cosmetic results.
Conclusions:
- The transcranial approach is favored for its wide access and ability to address orbital and nasal structures.
- A combined transcranial and transfacial approach may be necessary for optimal correction of nasal length and overall cosmetic outcome in FEC treatment.
Abstract:
In the treatment of frontoethmoidal cephaloceles (FEC), three aims should be pursued: (1) to provide good exposure for a safe neurosurgical correction, (2) to obtain the best cosmetic result with minimal scarring, and (3) to inflict on the child the least surgical trauma. Between 1986 and 1991, 6 children were operated on in our unit for FEC. In this study, we compare the advantages of the transcranial surgical approach versus the transfacial surgical approach. Because most of the facial anomalies presented by these patients are represented by modifications in the position and shape of the medial orbital walls, as well as elongation of the nose, we feel more comfortable using the transcranial approach. It permits safer translocation of the medial orbital walls and recreation of the dorsum of the nose with a calvarial bone graft, and provides wide access for neurosurgical correction. In our experience, the most difficult part of the operation remains correction of the length of the nose. The transfacial approach, with planned skin resection, may thus represent an advantage in these cases. Therefore, our purpose is not to oppose these two surgical procedures, but often to combine them for safer treatment and better cosmetic results.
