Características tomográficas de mucocele incomum de maxila

Mucoceles are a common injury of the oral mucosa, contained in the group of pathologies of the salivary glands. Besides this type of injury, it is important that health professionals become aware of the occurrence of lesions in other areas who also receive the name of mucoceles. These pathologies are benign paranasal sinus lesions, cyst-like structures, lined with a secretory respiratory mucosa of pseudostratified columnar epithelium. Despite its benign appearance, mucoceles exhibit aggressive behavior and may expand and cause erosion in surrounding tissues, leading to severe bone destruction. Here, we report a case of a unusual mucocele in midline of the maxilla with invasion of paranasal sinuses after orthognathic surgery, mainly focused on  tomographic features.
