Radiological Study of Maxillary Sinus using CBCT: Relationship between Mucosal Thickening and Common Anatomic Variants in Chronic Rhinosinusitis

The potential clinical relevance of anatomical structures and variations of the maxillary sinus for planned sinus floor elevation procedures: A retrospective cone beam computed tomography study

“…Limited data concerning the variable position of the MSO are available in CBCT studies. 40 In terms of position, the MSO is observed in the region of the posterior half of the infundibulum or posterior to the central point of the bulla ethmoidalis. 40 To the best of our knowledge, this is the first study to assess the location of the MSO based on the sinus floor and dentition.…”

“…40 In terms of position, the MSO is observed in the region of the posterior half of the infundibulum or posterior to the central point of the bulla ethmoidalis. 40 To the best of our knowledge, this is the first study to assess the location of the MSO based on the sinus floor and dentition. The most frequent location of the MSO was the middle region, and the mean distance between the MSO and the sinus floor was 28.5 mm, which may indicate a limitation for sinus augmentation procedures.…”

Usos y limitaciones de la tomografía computarizada de haz cónico (TCHC) y la tomografía computarizada multidetector (TCMD) en cirugía de cabeza y cuello:

“…Jorge Iván Mora Mendoza comunes son el engrosamiento de la membrana sinusal (Sneider), la acumulación de líquidos, la opacificación del seno y la presencia de pólipos (12). Estos hallazgos son importantes porque su presencia se correlaciona directamente con sintomatología sinusal de tipo obstructivo y pérdida del olfato (13); pero los estudios que en mayor proporción relacionan estos hallazgos son los que presentan patología odontogénica (12)(13)(14).…”

“…Algunos autores consideran que el engrosamiento de la membrana sinusal mayor a 2 mm se considera ya un hallazgo patológico en las mediciones tomográficas (14,15); pero, cuando este llega o supera los 5 mm, se asocia a un riesgo progresivo de obstrucción de ostium (16). Asimismo, es un factor de riesgo la presencia de pólipos (pseudoquistes) (15), lo cual no contraindica procedimientos como la elevación de piso de seno maxilar, pero sí son hallazgos que indicarían la interconsulta con un otorrinolaringólogo antes de la intervención.…”

Evaluation of Relationship Between Maxillary Sinus Pathologies and Ostium Dimension: A Retrospective Cone Beam Computed Tomography Study

“…The ostium of maxillary sinus is located on the highest part of the medial wall of the sinus and improper mucociliary activity of the mucosa in the maxillary sinus which is in charge of poor free drainage and it opens into the narrow ethmoidal infundibulum instead of direct opening into the nasal mucosa, so the inflammation of its adjacencies area can further hamper drainage (1,2). Capelli After all, they introduced the relationship between thickening of the sinus mucosa and obstruction of the maxillary ostium (3). Radiographically, the healthy maxillary sinus has many loci and lobulations with clearly defined margins.…”
