| Sumario: | Maxillary sinus or antrum of Highmore is a pneumatic cavity lodged inside the body of the maxilla. It is lined with sinusal mucosa or Schneiderian membrane. It is somewhat pyramidal in shape whose lower wall is also called sinus floor or alveolar wall. Sinus floor adquires importance by its morphology and size, presence of osseal septa and its relationship with the upper posterior teeth.
The aim of this study was to evaluate maxillary sinus shape and size, presence of bone septa and analyze the relationship with the maxillary posterior teeth, to avoid accidents in routine practice.
560 digital ortopnatomographies taken by Planmeca Promax 3D Classic unit were selected and analyzed. Software Romexis 4.4.0.R was used for the analysis of images.
Prevalence of the maxillary sinus medium size was founded. Large sinus was observed only in 23.88% of cases with a sex ratio 2: 1 (♂: ♀). Pronounced curve was the predominant floor shape (80%). The prosident sinus was had the lowest percentage (32%) with a sex ratio 2: 1. (♂: ♀). Maxillary sinus septa were observed in 20% of cases and in 75% in large maxillary sinuses. 1st and 2nd molar roots were always projected or touche the inferior wall of the maxillary sinus. 1st premolar root was rarely in contact with maxillary antrum when it is large.
It results from the present study that although largest and protruding maxillary sinuses have a low incidence, they have a close relationship with upper molar roots, therefore, routine radiographic examinations should be taken for a correct diagnosis in order to avoid possible complications or accidents in dental practice such as buco-sinusal communications or introduction of roots into maxillary sinus. |
