“…The APSS has also been demonstrated to correlate strongly with the total sinus vol-ume, thus can be used as a reliable measure of the overall prevalence of different anatomical configurations in large populations [9,10]. The prevalence of the anatomical variants of the SS cannot be generalized as incredibly significant differences have been observed among different ethnic groups [3]. These observations along with the lack of data in our population motivated the development of our study.…”

“…Hammer and Radberg first classified SS pneumatization into conchal, sellar, presellar, and postsellar [3]. This classification emphasizes posterior pneumatization in relation to the sellae and predicts the surgical corridor used for transsphenoidal surgeries [11].…”

“…Pneumatization of the ACP creates an optic-carotid recess, a small space in the superolateral portion of the SS limited superiorly by the ON and by the ICA inferiorly. Bulging and dehiscence of the ON into the aired space of the SS predispose it to iatrogenic injury and subsequent vision loss [3].…”

Introduction: Pneumatization of the sphenoid sinus (SS) varies widely among different ethnic groups. Information regarding the prevalence and significance of SS variants among Hispanic groups is limited. This study aims to describe and analyze pneumatization and septation patterns of the SS in a Hispanic population. Methods: A total of 160 paranasal sinus computed tomographies were reviewed by a head and neck-specialized radiologist and 2 otolaryngologists. Results: The postsellar and sellar types were the most frequent patterns of pneumatization observed, with a prevalence of 52.5 and 40%, respectively. Accessory septations were present in 59.4% of the patients. Septa were inserting over the internal carotid artery (ICA) in 43.8% and over the optic nerve in 17.5% of the population. No significant association (p > 0.05) was observed when comparing the different accessory septation patterns among the types of the SS. The frequency of septa inserting on the ICA was significantly higher in postsellar types (p < 0.001). Pneumatization of the anterior clinoid process, pterygoid processes, and greater wing was present in 20, 17.5, and 45.9% of the sinuses, respectively. Onodi cells were encountered in 40% of the sinuses. There were no significant differences in any of the pneumatization and septation variables when compared by gender and age (p > 0.05). Discussion/Conclusion: Differences regarding anatomical variants and septations of the SS were observed in our study when compared with findings reported in other ethnic groups. Preoperative assessment of the anatomical variants of the SS in Mexican patients is imperative to select the most optimal surgical approach and prevent iatrogenic injuries to related neurovascular structures.

The sphenoid sinus (SS) is one of the four paired paranasal sinuses (PNSs) within the sphenoid bone body. Isolated pathologies of sphenoid sinus are uncommon. The patient may have various presentations like headache, nasal discharge, post nasal drip, or non-specific symptoms. Although rare, potential complications of sphenoidal sinusitis can range from mucocele to skull base or cavernous sinus involvement, or cranial neuropathy. Primary tumors are rare and adjoining tumors secondarily invading the sphenoid sinus is seen. Multidetector computed tomography (CT) scan and magnetic resonance imaging (MRI) are the primary imaging modalities used to diagnose various forms of sphenoid sinus lesions and complications. We have compiled anatomic variants and various pathologies affecting sphenoid sinus lesions in this article.
