Teeth in maxillary sinuses

Background: Various anatomical parameters might influence the surgical approach for maxillary sinus floor elevation. The objective of the present study was to retrospectively evaluate the influence of anatomical parameters on the dimensions of the subantral space and of the sinus mucosa thickening after sinus floor elevation. Material and Methods: Seventy-eight maxillary sinuses in sixty-five patients were evaluated on cone beam computed tomographies taken before surgery and after one week (t1w) and nine months (t9m). Several parameters such as the distance XF between an axis parallel to the base of the nose (X-axes) and the sinus floor (F) were correlated with the height gain (IF) at t1w and t9m and the post-surgical edema. Results: A weak significant positive correlation was observed between height gain vs. sinus height of interest (XF), the balcony, and the sinus floor angle. The post-surgical edema was influenced by the initial mucosa thickness and the xenograft used. Conclusions: Various parameters might affect height gain and sinus mucosa thickening after sinus floor elevation. The height of interest, the balcony, and the sinus floor angle showed significant correlations with height gain. The initial thickness of the mucosa and the biomaterial used influenced the post-surgical edema.

Abstract Introduction The endoscopic access to lesions in the anterolateral wall of the maxillary sinus is a challenging issue; therefore, the evaluation of access should be performed. Objective To assess the accessibility of three endoscopic ipsilateral endonasal corridors. Methods Three corridors were created in each of the 30 maxillary sinuses from 19 head cadavers. Accessing the anterolateral wall of the maxillary sinus was documented with a straight stereotactic navigator probe at the level of the nasal floor and of the axilla of the inferior turbinate. Results At level of the nasal floor, the prelacrimal approach, the modified endoscopic Denker approach, and the endoscopic Denker approach allowed mean radial access to the anterolateral maxillary sinus wall of 42.6 ± 7.3 (95% confidence interval [CI]: 39.9–45.3), 56.0 ± 6.1 (95%CI: 53.7–58.3), and 60.1 ± 6.2 (95%CI: 57.8–62.4), respectively. Furthermore, these approaches provided more lateral access to the maxillary sinus at the level of the axilla of the inferior turbinate, with mean radial access of 45.8 ± 6.9 (95%CI: 43.3–48.4) for the prelacrimal approach, 59.8 ± 4.7 (95% CI:58.1–61.6) for the modified endoscopic Denker approach, and 63.6 ± 5.5 (95%CI: 61.6–65.7) for the endoscopic Denker approach. The mean radial access in each corridor, either at the level of the nasal floor or the axilla of the inferior turbinate, showed a statistically significant difference in all comparison approaches (p < 0.05). Conclusions The prelacrimal approach provided a narrow radial access, which allows access to anteromedial lesions of the maxillary sinus, whereas the modified endoscopic Denker and the endoscopic Denker approaches provided more lateral radial access and improved operational feasibility on far anterolateral maxillary sinus lesions.

Odontogenic infections can directly trigger maxillary sinusitis. CBCT is an excellent choice for precise examination of maxillary sinuses and hard tissues within the oral cavity. The objective of this retrospective and the cross-sectional study was to analyze the influence of odontogenic conditions on the presence and intensity of maxillary sinus mucous membrane thickening using CBCT imaging. Moreover, periodontal bone loss and anatomic relationship between adjacent teeth and maxillary sinuses were assessed to evaluate its possible impact on creating maxillary thickening. The study sample consisted of 200 maxillary sinuses of 100 patients visible on CBCT examination with a field of view of 13 × 15 cm. The presented study revealed a significant influence of periapical lesions, inappropriate endodontic treatment, severe caries, and extracted teeth on the presence of increased thickening of maxillary sinus mucous membrane. In addition, an increase in the distance between root apices and maxillary sinus floor triggered a significant reduction of maxillary sinus mucous membrane thickening. The presence of periodontal bone loss significantly increases maxillary sinus mucous membrane thickening.

Purpose: To study CT findings in general practice patients with a clinical diagnosis of acute sinusitis, and to examine the interobserver variation between 2 radiologists with regard to their CT evaluation. Material and Methods: Two hundred and one patients were examined with coronal CT images of the paranasal sinuses within 2 days of the clinical diagnosis. Patients with chronic sinusitis were excluded. Fluid level or total opacification of any sinus were used as evidence of sinusitis. Results: One hundred and twenty-seven (63%) patients had fluid level or total opacification in a sinus region, most in more than one region. One hundred and fifteen had CT signs of sinusitis in the ethmoid region, 84 in the maxillary, 18 in the frontal, and 10 in the sphenoid. Forty-nine patients had a negative CT. In the evaluation of interobserver agreement, the overall assessment of the CT yielded a kappa value of 0.70. Conclusion: The study demonstrated great variation in the CT findings in general practice patients with suspected acute sinusitis. More than one sinus region was affected in most patients in whom sinusitis was confirmed by CT imaging; the most common combination was ethmoid and maxillary sinuses. The interobserver agreement was substantial.

In order to analyze whether ultrasonography with a reasonable degree of confidence can replace radiography in the diagnosis of sinusitis, 138 patients with clinical signs of sinusitis were examined with both methods. It was found that maxillary sinus fluid was recognized ultrasonographically with a confidence that increased with the amount of fluid, judged from radiographic examinations. In a sub-group of 45 cases, fluid confirmed by maxillary sinus puncture was detected by ultrasonography in 35/45 sinuses (78%) and by radiology in 38/45 sinuses (84%). In patients with radiographically normal maxillary sinuses, the correlation to ultrasound was good. However, mucosal swelling and polyps or cysts observed at radiography were poorly demonstrated by ultrasonography. In addition, the ultrasound method was not reliable for frontal sinus diagnosis. It was concluded that ultrasonography can be recommended in maxillary sinusitis for follow-up of treatment and as a screening method before sinus radiography.
