“…This difference may be due to missed lesions in the other studies, because of the superposition of many anatomical structures in the maxillary sinus region. As a matter of fact, in the threedimensional radiographic studies, high rates of maxillary sinus opacities have been reported, similar to the results of our study (19).…”

The aim of this study is determination of the prevalence and clinical significance of random findings detected in digital panoramic images of complete edentulism patients, applied for prosthetic treatment. Material and Methods: Of the 382 images, 189 digital panoramic images (49.5%) matching the study criteria were included in the study. The positive findings were evaluated, such as impacted teeth, residual roots, radiolucent lesions, radiopaque (RO) lesions, foreign bodies, atrophic crest, soft tissue calcifications (STCs), maxillary sinus opacities, Stafne bone defects, stylohyoid ligament ossifications, and laryngeal cartilage calcifications. The findings were analyzed in different age groups and evaluated with descriptive analysis. Results: Images of 100 male (53%) and 89 female (47%) patients with a mean age of 64.2±9.6 were examined. It was found that 80% (n=151) of the patients were delivered conventional complete dentures, 20% (n=38) of them were delivered complete dentures in the upper jaw, and two implant-retained overdentures in the lower jaw. The detected positive radiographic findings were 94.7% (n=179); 48.7% (n=87) were in female and 51.3% (n=92) were in male. The most common positive findings were maxillary (50.7%) and mandibular (28.4%) crest atrophies, followed by maxillary sinus opacities (25.9%), and STCs in tonsilloliths region (18.5%). In all age groups, the most common positive finding was maxillary crest atrophy. Conclusion:The results of this study showed that the rate of positive findings detected in digital panoramic images of completely edentulous patients was high. Routine use and careful examination of panoramic images are essential for patients with complete edentulism.

“…MSCs were evaluated in sagittal and coronal slices, and diagnosis was based on the following radiographic characteristics (Fig. 1): a) A homogeneous dome-shaped opacity within the maxillary sinus, with sharp demarcation of lateral borders; b) Attachment of the bottom of the hemispherical opacity to the bone surface, and protrusion of the top into the sinus cavity; c) A continuous smooth spherical outline at the free border of the MSC; d) Absence of communication with apical lesions [15,16].…”

Purpose: This study used cone-beam computed tomography (CBCT) to assess the prevalence of and factors associated with maxillary sinus cysts (MSCs) in a Chinese population. Methods: A total of 2,571 CBCT scans of 5,000 sinuses were analyzed. MSCs were diagnosed on the basis of imaging features within the maxillary sinus. Sex, age, dental condition, and anatomic condition were assessed. Associations with these factors were evaluated with logistic regression and a generalized estimating equations model. Results:The prevalence of MSCs was 15.46% at the sinus level and 23.44% at the patient level. The prevalence of MSCs was higher for men (OR = 1.864, P < 0.001) and for patients with apical lesions (OR = 1.76, P < 0.001), severe bone loss (OR = 1.363, P < 0.05), tooth roots in contact with the sinus floor (OR = 1.68, P < 0.001), and pits or septa on the floor of the maxillary sinus (OR = 1.539, P < 0.001). Conclusion:This large sample had a high prevalence of MSCs. MSC prevalence was associated with multiple factors, including sex, dental condition, and anatomic condition. Maintenance of healthy dental and periodontal status might help prevent MSCs.

Su drenaje se realiza a través del ostium nasal, con lo que obtiene ventilación a través de esta vía y mantiene su balance biológico; por ello, su obstrucción causaría la disminución de la ventilación y el drenaje ( [6][7][8] ).…”

Introducción: Por medio de la tomografía computarizada de haz cónico pueden observarse alteraciones en los senos maxilares, como opacidades, ocupación de espacio y engrosamiento de la mucosa. Existen factores que contribuyen a dicho engrosamiento, entre los que destacan los factores dentales, la periodontitis, la patología apical y los tratamientos endodónticos. Objetivo: Evaluar la asociación entre cambios observados en los senos maxilares y lesiones apicales mediante tomografía computarizada de haz cónico. Materiales y métodos: Fue un estudio descriptivo con un diseño retrospectivo y transversal, correlacional, de campo, no experimental. La muestra estuvo conformada por 115 volúmenes tomográficos obtenidos por medio de un equipo Planmeca ProMax 3D Classic (Planmeca, Helsinki, Finlandia). Se evaluó la presencia/ausencia de tratamiento endodóntico en los dientes posteriores presentes, presencia/ausencia de lesión periapical asociada con estos dientes, tamaño de la lesión periapical, presencia/ausencia de alteración en el seno maxilar y su espesor. Resultados: Se observaron lesiones apicales que promediaron un tamaño de 3,32 ± 1,82 mm, y casi la mitad (44,35%) presentó entre 2 y 4 mm de tamaño. La principal alteración del seno maxilar que se observó fue el engrosamiento de la mucosa (58,26%). El espesor promedio del engrosamiento de la mucosa sinusal fue de 3,51 ± 1,78 mm, con un 72,17% de los casos con engrosamientos mayores a 2 mm. Conclusión: Hubo asociación entre los cambios observados en los senos maxilares y lesiones apicales. Mientras más grande y cercana estaba la lesión respecto del seno, mayor era el engrosamiento de la mucosa sinusal.
