[Puncture of the maxillary sinus (author's transl)].

In some texts on operative technique it is recommended, when puncturing the maxillary sinus via the inferior meatus, to aim towards the outer canthus of the eye. It is demonstrated on a skull that aiming at the inner canthus avoids the danger of piercing the premaxillary tissue and in addition the diameter of the sinus is greater at this angle.
