Abstract
Bulges of the most posterior ethmoid air cells into the maxillary sinus were termed maxillary bullæ by Onodi. With few exceptions, they have since been ignored by anatomists through time. Likewise, Sieur cells—the spheno-ethmoido-maxillary air cells—are uncommonly found in anatomical texts. We therefore aimed to perform a retrospective cone beam computed tomography study on 50 patients to document the possibilities of anatomic variation in the situs of the orbital process of palatine bone—a variation related anatomically with the pterygopalatine fossa (PPF) and the respective angle of the maxillary sinus. Commonly occurring pneumatizations in this situs were the Sieur cell (58 %/64 % right/left side), and the maxillary recess of the sphenoidal sinus (20 %/22 % right/left side). Alone or in combination, these determined, but not exclusively, the maxillary bullæ. Uncommon pneumatizations in the anterior wall of the PPF were also found, such as a sphenoidal recess of the maxillary sinus, and lateral (maxillary, or pterygopalatine) recesses of the middle and superior, respectively, nasal meatuses. In two different cases, non-Haller, and non-Sieur posterior ethmoid air cells were found extruded posterior to the maxillary sinus. Significant statistical association indicated bilateral symmetry of Sieur’s cell and of the maxillary recess of the sphenoidal sinus. It is important to identify such variant pneumatizations on a case-by-case basis in different surgical procedures and endoscopic corridors.

Fig. S8 Case study on multiplanar reconstructions (MPRs), coronal (in posterior-to-anterior series a–g), and left sagittal (in lateral-to-medial series h–j). Additional details result from Fig. 7 and Figs. S9 and S10. On coronal MPRs the posterior chamber within the left maxillary bone appears to be a huge extruded posterior ethmoid air cell, while the anterior chamber is a hypoplastic maxillary sinus. a Left greater palatine canal (7) that opens superiorly into a wide PPF determined by the left maxillary atrophy. b Right maxillary sinus (3) and the ethmoido-maxillary air cell (2), which produces a MB and drains above the middle nasal turbinate (arrowhead); on the left side the canal of the infraorbital nerve (8) courses on the lateral side of the posterior maxillary pneumatization (chamber) (5). c Opening (*) by which the ethmoido-maxillary cell communicates with a suprajacent posterior ethmoid cell; on the left side the canal of the infraorbital nerve (8) courses on the lateral side of the posterior maxillary pneumatization (5), which drains above the middle turbinate (arrowhead), thus being validated as a huge posterior ethmoid cell displaced within the maxillary bone. d Right infraorbital canal (9) in normal anatomical position; the ethmoid cell displaced within the left maxillary bone appears as the lower, maxillary part of a complex pneumatization, continued superiorly by a neck (arrowhead) that links it with a proper posterior ethmoid cell. On the left side the canal of the infraorbital nerve keeps its lateral position to the maxillary pneumatization (8). e Right infraorbital canal (9) lies in the roof of the maxillary sinus but on the left side is in a lateroantral position (8) as referred to the anterior chamber (hypoplastic left maxillary sinus) of the maxillary bone (4). The slice in f depicts the same anatomic structures as in e. g Left hypoplastic maxillary sinus (4) draining in the ethmoidal infundibulum (10). On sagittal MPRs the course of the canal of left infraorbital nerve (white arrows) is observed lateral to the maxillary bone pneumatizations: posterior/ethmoidal (5) and anterior/ hypoplastic maxillary (4) (TIFF 2625 kb)
