Abstract

Pneumatization  of  the  maxillary  sinus  is  its  extension  towards  the  alveolar  process.  During  development, it is a physiological event in which this structure increases in volume and fills with air. The maxillary sinuses can extend towards the anatomical regions of the maxillary bone forming extensions, which are usually described as recesses or diverticula: orbital, excavated in the ascending process of the maxilla in f ront of the lacrimal duct, malar or zygomatic, alveolar, upper and lower palatal. Palatine extension is observed as a bony excavation at the level of the hard palate, below the nasal fossa and in relation to the medial wall of the maxillary sinus. A case of a 16-year-old female patient is described who was referred for a cone beam computed tomography study to evaluate an image observed in the right maxillary region on the panoramic radiograph, similar to a periapical lesion.  In  panoramic  reconstructions,  the  alveolar  extension  of  the  right  maxillary  sinus  and  the  presence of an intrasinusal septum were observed, giving it a lobulated appearance. The axial views showed the extension of the maxillary sinus in the thickness of the hard palate, locating inferiorly to the floor of the nasal fossa and palatal to teeth 14 and 15. The tomographic examination allowed to make the definitive diagnosis of palatine extension, ruling out the presence of a intraosseous lesion.
