Background:Several anatomical variations can lead to the inflammation of the paranasal sinuses; therefore, surgeons should be familiar with these variations and their impacts on the status of the paranasal sinuses.Objectives:The present study aimed to determine the prevalence of Haller cells and its association with patients’ sex and age. Furthermore, the relationships between the presence and size of Haller cells, deviation of the uncinate process and size of the maxillary sinus ostium with the occurrence of maxillary sinusitis were investigated.Materials/ Patients and Methods:120 coronal CBCT images were retrieved and analyzed. Statistical analysis of the data was performed by means of Mann - Whitney, χ2and T tests.Results:There were statistically significant associations between the presence and surface area of Haller cells and the occurrence of ipsilateral maxillary sinusitis. Neither the angulation of the uncinate process nor the size of the maxillary sinus ostium significantly correlates with the formation of maxillary sinusitis.Conclusion:Haller cells can interfere with the normal drainage of the maxillary sinus and result in sinusitis. In contrast, diameter of the sinus ostium and deviation of the uncinate process do not influence the inflammatory status of the maxillary sinus significantly.

Objective: We investigated the anatomical and dental factors associated with unilateral maxillary sinus fungal ball (MSFB). Also, we evaluated the effect of combinations of those factors on the incidence of MSFB. Methods: Three hundred patients were divided into MSFB, normal, and chronic rhinosinusitis (CRS) groups. We reviewed paranasal computed tomography scans for the presence of deviated nasal septum, concha bullosa (CB), Haller cells, and various dental factors. Also, we measured the ethmoid infundibulum, maxillary natural ostium, and CB. Results: Maxillary sinus fungal ball showed a more significant association with CB compared to the other 2 groups (37%, P < .05). The MSFB group had a lower rate of Haller cells than the normal group (10% vs 22%, respectively; P < .05). Also, the MSFB group had a wider maxillary sinus ostium than the normal group (7.07 ± 1.8 vs 5.48 ± 1.3 mm; P < .01). Moreover, the combination of CB and Haller cells was significantly associated with a decreased rate of the fungal ball ( P = .047, odds ratio = 0.694). The dental factors were more prevalent in the MSFB and CRS groups (73% and 75%, respectively) than in the normal group (32%, P < .001). Conclusions: Maxillary sinus fungal ball is significantly associated with CB, Haller cells, an increased maxillary sinus ostium size, and dental factors.

Increased Risk

Preoperative evaluation of maxillary sinus anatomy is very important to avoid surgical complications due to close anatomical relations between the sinus and the posterior maxillary teeth and/or edentulous alveolar ridge. Posterior superior alveolar artery is a branch of the maxillary artery and provides the vascularization of the lateral sinus wall and underlying mucosa. Maxillary artery branches should be taken into consideration during sinus lifting procedures and bone augmentation due to increased risk of bleeding by damaging the artery during the osteotomy. Computed tomography (CT) explores three-dimensional anatomic structures and provides complex and accurate information about them. Cone Beam Computed Tomography (CBCT) offers an accurate view of the teeth and surrounding structures at high resolution, despite low-dose radiation used. In this study, the incidence of anatomical variations and sinus pathology were assessed using CBCT. The aim is to evaluate the presence of sinus pathology (sinus mucosal thickening, oro-antral communications, sinus tumors, cysts, polyps), presence and position of the posterior superior alveolar artery. These issues are important because they are about the limits of the dental implants in the posterior maxillary area. The presence of sinus pathology and anatomical variations may predispose to complications and even failures of implantation therapy.

Sinus Ostium

Chronic maxillary sinusitis may present as atelectasis of the sinus with changes to surrounding structures. Several mechanisms have been proposed for this problem. Chronic obstruction of the sinus ostium, with resultant retention of secretions and osteitic bone resorption, may account for these changes. Enophthalmos is one manifestation that may require corrective treatment. Titanium micromesh reconstruction of the orbital floor, with or without onlay concha cartilage, has reliably resolved the enophthalmos. Reconstruction of the orbital floor and ventilation of the obstructed sinus ostium may be carried out relatively safely in a single operation. The standard endoscopic technique of uncinate removal and middle meatal antrostomy should be modified to prevent orbital penetration. This report reviews our series of 6 patients with this problem, as well as a comprehensive review of the literature. Recommendations for management of both the obstruction and the secondary orbital manifestations are presented.

Sinus Ostium

The effect of topical oxymetazoline hydrochloride on the blood flow of the nasal and sinus mucosa of the rabbit was measured by laser-Doppler flowmetry. Oxymetazoline, the active component in clinically used nose drops, induced a dose-dependent decrease of the nasal mucosal blood flow. This effect has previously been shown in humans and suggests the presence of α2–adrenoceptors in the nasal mucosa of the rabbit. Doses of oxymetazoline used clinically in humans induced a 50% reduction of blood flow in rabbits. Rhythmic variations in blood flow were seen in 30% of the rabbits after administration of oxymetazoline. Additionally, oxymetazoline induced a dose-dependent decrease of the mucosal blood flow in the maxillary sinus when the drug was applied in the nose. A vasoconstricting effect of oxymetazoline on the arteries penetrating the maxillary sinus ostium is a possible explanation. This can have positive as well as negative consequences on acute sinus infections.
