Application of the skull base technique to the repair of transsphenoidal meningoencephaloceles.

A 2-month-old boy with an anterior basal meningoencephalocele of the transsphenoidal type was successfully treated via the transbasal intra- and extradural approach. Magnetic resonance imaging was useful for obtaining a precise diagnosis, and the transbasal combined approach is suitable for this type of meningoencephalocele.
