[Therapy problems in sphenoethmoidal meningoceles]
Insights
This study details a complex sphenoethmoidal meningocele case in a child, highlighting a novel transpalatinal-transnasal surgical approach for successful meningocele removal and palate defect repair.
Area of Science:
- Neurosurgery
- Pediatric Neurology
- Craniofacial Surgery
Background:
- Meningoencephaloceles are rare congenital abnormalities involving brain tissue herniation through skull defects.
- Sphenoethmoidal meningocele is a specific subtype presenting significant diagnostic and therapeutic challenges.
- Associated anomalies, such as palate clefts and agenesis of the corpus callosum, suggest a primary central developmental disturbance.
Observation:
- A five-year-old boy presented with a large sphenoethmoidal meningocele (3x3x4 cm).
- The patient also exhibited a wide median palate cleft, agenesis of the corpus callosum, and median cheiloschisis.
- Initial attempts at intracranial occlusion of the skull base defect were unsuccessful.
Findings:
- A successful surgical outcome was achieved using a transpalatinal-transnasal extradural approach.
- This involved repositioning the meningocele, removing epipharyngeal mucosa, and securing the bony defect with a tantalum plate.
- Subsequent closure of the palate cleft was performed by an oral surgeon.
Implications:
- The described transpalatinal-transnasal extradural technique offers a viable alternative for treating complex sphenoethmoidal meningoceles.
- This approach may be beneficial for managing challenging transsphenoidal meningocele cases.
- Multidisciplinary collaboration is crucial for managing these complex congenital anomalies.
Abstract:
After a brief survey of the forms of cranial meningoencephaloceles, the current opinions on their development, symptoms and surgical therapy, a report is given on the case of a five-year-old boy suffering from a sphenoethmoidal meningocele of the size 3 x 3 x 4 cm. There was at the same time a wide median palate cleft, obviously a consequence of the meningoencephalocele. A further finding presented by the boy was a neuroradiologically diagnosed agenesis of the Corpus callosum and a median cheiloschisis. This suggests a central development disturbance as a primary cause. The attempt to perform an intracranial occlusion of the defect of the base, which was repeated twice, was not successful. It was only by a transpalatinal-transnasal extradural intervention (reposition of the meningocele after removing the epipharyngeal mucosa, blocking of the bony defect with a perforated tantalum plate) that the removal of the meningocele was successful. The closure of the palate cleft was then made by the oral surgeon. This surgical intervention may also be considered for the treatment of the transsphenoidal meningoencephalocele, which also presents many problems.
