title: Anatomy of the pterygopalatine foramen and the fontanella in the lateral nasal wall.
abstract: A dissection study of 20 cadaver specimens gives a firm knowledge of the anatomy of the pterygopalatine foramen in the middle and upper meatus of the nose. Measurements of the proportions between the end of the middle concha, the hiatus semilunaris and the foramen are described. A new, curved needle for puncturing of the maxillary sinus through the fontanella is shown.
