Not illustrated. 1901 Excerpt: ...of the posterior one is into the superior meatus, into which the cells of the orbital process of the palate bone open, it seems evident that this is an enlarged palatal sinus or cell, and not a divided maxillary sinus. Fig. 49 is from another section made through the molar teeth and the center of the orbit. Posterior to the maxillary sinus, we find another sinus of a different character, which from superficial observation might be thought to be related to it or Fig. 49. A B Antero-posterior division through the center of the orbit, maxillary sinus, and molar teeth, showing a large maxillary sinus and a large sphenoidal sinus. to be an enlarged cell belonging to the palate bone. A probe passed into it leads into the supreme or fourth meatus of the nose, indicating that it may be related to or connected with the sphenoidal sinus. In fact, it is a very large sphenoidal sinus extending out laterally in a line almost to the outer part of the maxillary bone. Fig. 50 gives a view of the external walls of the nasal fossae of the same skull as Fig. 49. The sphenoidal sinus shown in B extends laterally until it forms the cavity posterior to the maxillary sinus seen in Fig. 49. It will be observed that this large sphenoidal sinus extends well forward toward the frontal bone and backward toward the basilar process of the occipital bone. Fig. 51 is an outer and inner view of a section showing an extremely large sphenoidal sinus. In A the cut is made through the premolar teeth, and a little to the inner side of External walls of right and left nasal chambers, with large sphenoidal sinuses, B having four meati. Fig. 51. Two views of an antero-posterior section. A shows the inner wall of the orbit, maxillary sinus, and openings leading into the sphenoidal sinus. B shows th...
