THE INTERSPHENOID SYNCHONDROSIS

Abstract
1. The intersphenoid synchondrosis remains patent in normal children until the age of approximately 3 years. 2. The sphenoidal cleft is the roentgen manifestation of the intersphenoid synchondrosis. 3. It occurs in 64 per cent of infants less than 1 month of age, progressively decreases to 28 per cent in all children less than 3 years of age. 4. It has no pathologic significance. 5. Its roentgen detection is determined by age, roentgen technique and anatomic positioning. 6. Channels described as the craniopharyngeal canal appear to be vascular in origin and no roentgen or anatomic confirmation of such a canal as an entity is found.
