The anterior ethmoidal artery (AEA) is an important point for frontal and ethmoid sinuses surgery. CT scans can identify landmarks to help the surgeon find the AEA. Aim: To identify the landmarks of the AEA on the orbital medial wall and on the lateral wall of the olfactory fossa. and to correlate the presence of supraorbital ethmoidal cells with spotting the anterior ethmoidal artery canal. Materials and Methods: Retrospective review of 198 direct coronal paranasal sinuses computed tomography (CT) scans from August to December, 2006. Results: Supraorbital pneumatization was seen in 35% (70 scans). The AEA canal was seen in 41% (81 scans). The anterior ethmoidal sulcus was seen in 98% (194 scans) and the anterior ethmoidal foramen was seen in all the scans (100%). Conclusion: The anterior ethmoidal foramen and the anterior ethmoidal sulcus were anatomical landmarks present in almost 100% of the scans studied. There was a correlation between the presence of supraorbital pneumatization and AEA canal visualization.

“…5 Different types of anatomic variations of the middle turbinate have been described in the literature as pneumatized, lateralized, hypoplastic and hypertrophic, paradoxally curved, secondary and accessory, bifurcate and trifurcate middle turbinate. [6][7][8] CB is the most frequently encountered anatomical variations of the middle turbinate. Bolger et al classified CB as lamellar, bullous and extensive depending on the degree of pneumatization and localization.…”

The term of septated concha bullosa has been described recently and it is an uncommon pneumatization anomaly of the middle turbinate. Solitary, benign soft tissue masses originating at the maxillary sinus and extending to the nasopharynx are called antrochoanal polyps. Antrochoanal polyp may be accompanied by concha bullosa. However, combination of septated concha bullosa and antrochoanal polyp has never been reported to the best of our knowledge. This paper presents a 45-year-old male patient who has a combination of septated concha bullosa and antrochoanal polyp.

“…The frequency rates of Haller's cell have been variously reported to be between 6 and 51% [17,[19][20][21][22][24][25][26][27]. These cells are closely related with the maxillary sinus ostium, and according to its size, they may negatively affect the maxillary sinus ventilation (Figure 3).…”

“…In case of extensive pneumatization as a continuation of the ethmomaxillary plate, a thin-walled separating partition between the sphenoid and maxillary sinus is called sphenomaxillary plate (SMP) (Figure 9) [25,45,46]. It is important to identify this anatomic variation which may be mistaken for posterior ethmoid cells during transantral ethmoidectomy and increases the risk of inadvertent entry to the sphenoid sinus [45].…”

Paranasal Sinuses

View full text Add to dashboard Cite

Paranasal sinuses located in the bones surrounding the nasal cavity are called maxillary, ethmoid, frontal and sphenoid sinuses. In relation with their location, these sinuses contribute to the development of the facial structures, jaws and upper airway. During the developmental process of the paranasal sinuses, anatomic variations can occur in consequence of intra and extramural migration of the ethmoid air cells, overpneumatization or hypoplasia of the sinuses and bulging of the neurovascular structures to the sinuses. Some of these anatomic variations may affect the drainage pathways, pave the way for chronic infections and cause difficulties when performing paranasal sinuses surgery.Therefore, the aim of this chapter was to examine the paranasal sinus anatomic variations with cone beam computed tomography (CBCT).
