Insights
This study reviewed 30 anterior encephalocele cases, finding one-stage repair effective for fronto-ethmoidal defects, particularly in infants. Surgical outcomes were positive with no mortality, emphasizing the benefits of early intervention.
Area of Science:
- Neurosurgery
- Pediatric Surgery
- Craniofacial Surgery
Background:
- Anterior encephalocele is a congenital condition requiring surgical intervention.
- Early surgical management is often indicated for anterior encephalocele.
- Fronto-ethmoidal defects are a common subtype of anterior encephalocele.
Observation:
- Thirty anterior encephalocele cases were treated between 1973 and 1990.
- Over 60% of patients were under 2 years old at surgery; 40% under 1 year.
- Fronto-ethmoidal defects predominated (26 cases), with associated hypertelorism in 25 children.
Findings:
- One-stage repair of encephalocele and orbital reconstruction was performed in 26 patients.
- No postoperative mortality was observed.
- Postoperative CSF rhinorrhoea occurred in 6 patients, with 3 requiring shunts.
Implications:
- One-stage repair is a viable and effective surgical approach for anterior encephalocele.
- Early surgical intervention in infants with anterior encephalocele yields favorable outcomes.
- Management of associated hydrocephalus and CSF complications is crucial.
Abstract:
Thirty cases of anterior encephalocele treated in our centre over an 18-year period (from 1973 to 1990) are presented. At the time of surgery over 60% of the patients were under the age of 2 years, and 40% were aged under 1 year. Only one child was over 10 years of age. Twenty-six patients had the fronto-ethmoidal type of defect, while two each had frontonasal- and naso-orbital-type lesions. Twenty-five children had varying degrees of hypertelorism. Four had an enlarged head and four microcephaly. In 26 patients one-stage repair of the encephalocele and reconstruction of the orbits was undertaken. A ventriculoperitoneal shunt was performed prior to definitive surgery in three patients with gross hydrocephalus. There was no postoperative mortality. Six patients had postoperative CSF rhinorrhoea, three of them requiring a lumboperitoneal shunt. This study highlights the role of one-stage repair of this defect.
