[A case of 9p-deletion syndrome with congenital median nasal fistula].

We report a case of 9p-syndrome with congenital median nasal fistula in a boy born to a 28-year-old mother as the second child by normal delivery. The fistula opened at the base of the bridge of the nose and ran between the nasal septum cartilage to the anterior cranial fossa. A frontal craniotomy and transcolumellar skin incision were conducted to extirpate the fistula. In the 10 months since, no fistula has recurred.
