Evaluation of the effect of periapical lesions and other odontogenic conditions on maxillary sinus mucosal thickness characteristics and mucosal appearance: A CBCT study

Background. This retrospective study aimed to investigate the effect of various dental and maxillary sinus variables on maxillary sinus mucosal thickness (MT). The variables included periodontal bone loss (PBL), periapical status, dental restorations of posterior maxillary teeth, and the distance from the root apices to the sinus mucosa. Methods. Cone-beam computed tomography (CBCT) images of the maxillary sinuses (n=600) in 300 patients were examined. The sinus MT and the distance of the roots from maxillary sinuses were measured. Apical lesions of the roots, PBL, and situations of adjacent teeth were recorded. The relationships between these conditions and MT and characterization of MT were evaluated. The Kruskal–Wallis H test was used to compare groups due to the non-normal distribution of the data. The relationship between categorical variables was analyzed using chi-squared test. Results. There was a significant correlation between maxillary sinus MT and periapical lesions, PBL, and restorations (P<0.05). MT increased as the apical lesions of premolar teeth enlarged (P<0.05, P=0.022). MT increased in cases of mild PBL of molar teeth (P=0.041). Conclusion. In this retrospective study, the MT significantly increased in patients with periapical lesions, inadequate endodontic treatment, increased PBL, and inadequate dental restorations.

Background: Various parameters are known to affect the amount and type of mucosal thickening. The aim of this retrospective study was to investigate these effects through a survey of cone-beam computed tomography (CBCT) images. CBCT scans of 150 patients, which included the area of the MS and maxillary teeth (canine, first premolar, second premolar, first molar, second molar, and third molar), were evaluated retrospectively for the presence of sinus mucosal thickening. The parameters evaluated as possible causes of mucosal thickening were age, sex, tooth type, proximity to the maxillary sinus, endodontic treatment, and periapical lesion. Descriptive statistics and multiple logistic regression were used to analyze the data. A total of 28% of the teeth presented with mucosal thickening, which was associated with periapical lesions in 57.1% of 77 cases. The size of the lesion was the only parameter that was found to be significantly connected to the presence of mucosal thickness. More than 50% of teeth with periapical lesions in the posterior maxilla exhibited mucosal thickening. Other parameters such as age, sex, and the position of the root tips in relation to the MS floor did not influence the probability of developing mucosal thickening.

Today, there are several diagnostic methods that allow you to determine the exact size and nature of periapical formations. In addition, there are studies that describe the thickening of the sinus mucosa in patients with periapical lesions and show a causal relationship. Objectives: This study was to study the morphological changes in the cysts of the maxillary sinus. Methods: 50 patients with maxillary sinus cysts were evaluated. A total of 50 maxillary sinuses (13 men and 12 women) were analyzed taking into account changes in density in the sinus cavity. The thickening of the sinus mucosa and periapical lesions was measured in the caudal-cephalic direction. The axial and sagittal axes were taken as a basis on the sagittal and coronal sections. The presence of opacities was not directly related to periapical lesions. Conclusions. Lesions of the maxillary sinus floor have been associated with chronic periapical lesions larger than 4 mm. Clouding or thickening of the sinus mucosa was not associated with periapical lesions.

ABSTRACT Introduction The present study was undertaken to evaluate the anatomy of the maxillary sinus in relation to its position and the height of its septa, using cone beam computed tomography (CBCT). Materials and methods In this descriptive retrospective study, 300 CBCT images of maxillary sinuses of patients with posterior maxillary edentulism were evaluated. The maxillary sinus septa were evaluated in relation to their prevalence, height, and position; t-test and Mann–Whitney tests were used for the analysis of data. Results Sinus septa were detected in 44% of the subjects, with equal frequencies in the anterior, middle, and posterior positions. The mean height of the septa was 3.6 ± 1.56 mm. Conclusion In a population of Iranian subjects, in half of the cases, the sinus septa might be present in the anterior, middle, and posterior positions. Clinical significance In order to avoid intraoperative problems during sinus lift procedures, it is necessary to accurately evaluate the sinus, preferably with the use of CBCT.

A retrospective study was undertaken to determine the incidence of sinusitis as a source of fever in the intensive care unit (ICU) patient, evaluate the effectiveness of radiologic studies in diagnosing sinusitis, and develop guidelines that may help predict the result of antral levage. Sixteen of 52 (30.7%) lavages in patients studied with plain films and 27 of 67 (40.3%) lavages in patients studied with computed tomography of the sinuses revealed purulence in the maxillary sinuses. Conversely, 23 of 30 (76.7%) of the cases with purulence in the middle meatus had purulence in the maxillary sinus (chi-squared = 27.1). If no purulence was seen, the results of the antral lavage were negative in 68 of 89 cases (76.4%). When physical examination was used in conjunction with computed tomography, 92.3% of lavages confirmed purulence in the maxillary sinus (chi-squared = 16.6). In conclusion, the most important factor in predicting a positive result with antral lavage is the presence of purulence in the middle meatus on physical examination in conjunction with the presence of sinus disease on computed tomography of the sinuses.

Maxillary Sinuses

This study sought to assess the internal anatomy of the maxillary sinuses and their septa using cone-beam computed tomography (CBCT) in an Iranian population. Materials and Methods: Resorption of alveolar bone decreases the height of the maxillary alveolar ridge. This height reduction may be so severe that it warrants ridge augmentation by a sinus lift. Manipulation of the maxillary sinuses, as in sinus lift surgery, requires adequate knowledge about the sinus anatomy. Results: Maxillary sinus septum, as an anatomical variation, may complicate the surgical procedures and increase the risk of complications such as sinus membrane perforation. In this retrospective study, 366 sinuses, 190 from females and 176 from males, aged between 10 and 65 years old presenting to the Oral and Maxillofacial Radiology Department of School of Dentistry at Hamadan University of Medical Sciences were evaluated by two oral radiologists. The extension of the maxillary sinuses, presence of septa, number of septa and their location were determined. Data were analyzed using the chi square test (level of significance p≤0.001). The coefficient of agreement between the two oral radiologists was calculated based on Cohen kappa. Septa were present in 40.5% of the maxillary sinuses, out of which, 31.6% had one, 7.9% had two and 1% had three or more septa; 38% of the septa were horizontal while 62% had an oblique orientation. In total, 184 septa were found in 183 patients; out of which, 91 septa were 2 to 5 mm long while 93 septa were longer than 5mm. Conclusions: Comprehensive knowledge about the three-dimensional internal anatomy of the maxillary sinuses acquired by CBCT prior to surgical procedures can greatly help to prevent postoperative complications.

Introduction: The pandemic produced by SARS-CoV-2 has obliged us to set up the tele-assistance to offer a continuity of care. This implies an innovation, being the degree of satisfaction of patients unknown. Methods: A telephonic survey was conducted with the validated in the Spanish tool Telehealth Usability Questionnaire (Telehealth Usability Questionnaire; rating from 1-7) of all candidate patients assisted consecutively in the Coloproctology Unit. We included demographic variables, education level, job status, diagnosis and consultation type. A descriptive study was done. The relationship between the willingness of consultation model in the future (telemedicine vs traditional) and the categorical variables was analysed through the chi-squared test. Results: A total of 115 patients were included. The average age was 59.9 years, being 60% women. The average score in each of the survey items was higher than 6 in all the questions but 1. 26.1% of the surveyed patients confessed being advocated to tele-assistance in the future. The only factors related to greater willingness to tele-assistance were male gender (37% vs 18.8%; P = .03) and a higher academic preparation level in favour of higher technical studies (35.9%) and university studies (32.4%) opposite to the rest ( P = .043). The rest of variables studied, job status, labour regimen, diagnostic group and consultation type did not show any relationship. Conclusions: A vast majority of patients answered favourably to almost all the items of the survey. However, only 26.1% of them would choose a model of tele-assistance without restrictions.

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.

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.
