title: Nasal encephalocoele. Treatment by trans-cranial operation.
abstract: Results are described of 86 intracranial operations for the repair of nasal encephalocoele children at the Lahore Neurosurgical Centre in the last 13 years. These midline lesions at the base of the anterior cranial fossa have been considered in the past to be inoperable and even when operable, unpleasantly difficult. The intracranial approach has made it possible to treat this condition satisfactorily with comparatively few complications. Attempts at extra-cranial repair have met little success as they do not take into account the basic embryology and anatomy of the condition and fail to tackle the sac at the patent foramen caecum, the neck of the sac. This paper describes the embryology, anatomy, basic pathology and clinical features of the condition with characteristic X-rays showing the patent foramen caecum and outlines the operative repair.
