Cephaloceles: classification, pathology, and management--a review

Area of Science:

• Craniofacial Surgery
• Pediatric Neurosurgery
• Medical Genetics

Background:

• Cephaloceles encompass a spectrum of congenital conditions affecting the skull and brain.
• Meningoencephaloceles, a subset of cephaloceles, are frequently managed by craniofacial surgeons.
• Frontoethmoidal meningoencephaloceles represent a distinct entity with unique pathological characteristics.

Purpose of the Study:

• To review the spectrum of diseases causing cephaloceles, with emphasis on craniofacial conditions.
• To describe the specific pathology and natural history of frontoethmoidal meningoencephaloceles.
• To discuss the classification and treatment principles for basal and posttraumatic encephaloceles.

Main Methods:

• Review of existing literature on cephaloceles and related craniofacial anomalies.
• Analysis of case data from the Australian Craniofacial Unit (1975-1993) focusing on frontoethmoidal meningoencephaloceles.
• Examination of classification systems and treatment modalities for various encephalocele types.

Main Results:

• Frontoethmoidal meningoencephaloceles exhibit unique features that distinguish them from other cephaloceles.
• The natural history of frontoethmoidal meningoencephaloceles significantly influences management strategies.
• While associated craniofacial clefts do not alter treatment, the specific cephalocele type is paramount.

Conclusions:

• Effective management of frontoethmoidal meningoencephaloceles necessitates a thorough understanding of their distinct natural history.
• Long-term follow-up data provides valuable insights into optimal treatment approaches for cephaloceles.
• Classification and understanding of pathogenesis are key to successful surgical intervention for basal and posttraumatic encephaloceles.
