After having tried nearly all known varieties of antrum puncture trocars, I came to the conclusion that the Lichtwitz needle best answers the purpose, because the use of a straight needle is correct when one bears in mind the anatomic region to be invaded.
The maxillary process of the inferior turbinate forms the thinnest osseous portion of the lateral wall.
The pars membranacea is the thinnest portion of the nasal wall of the antrum. It consists of only two layers of mucous membrane, antral and nasal. Its anatomic boundaries are: above, the lamellae of the bulla; below, the superior margin of the inferior turbinate; in front, the anterior attachment of the processus uncinatus and behind, the ramus of the palate bone.
Judging from the ease with which the puncture of the antrum is made when the needle is directed close to the attachment of the inferior turbinate, one may assume
