[Congenital nasal cysts and fistulae].
Congenital nasal cysts and fistulae are relatively rare. Their localization is usually medial, sometimes lateral at sites of facial junctions during the embryonic period, either above or below the nasal bones. In a group of 16 children operated in the course of 25 years on account of a congenital nasal fistula or cyst the authors encountered in two instances junction of the fistula with the dura mater. According to the histological examination dermoids or epidermoids were involved. As the pressure of the cyst may cause usuration of bone and distension of the osseous nasal skeleton, it is recommended to operate as soon as possible.
