Floor Of Maxillary Sinus X Ray

The floor is formed by the alveolar process and if the sinus is of an average size is on a level with the floor of the nose.

Floor of maxillary sinus x ray.

Described as a pyramid the maxillary sinuses have a base on the lateral border of the nose with the apex pointing towards the zygomatic. A sinus x ray uses a small amount of radiation to create an image of your sinuses. If the sinus is large it reaches below this level. Left orbital floor fracture.

No evidence of rectus muscle entrapment retrobulbar hemorrhage or proptosis. Left orbital floor fracture is depressed by 3 5 millimeters. Superior alveolar greater palatine and infraorbital nerves. The maxillary sinus is the largest and simplest in shape among all sinuses and is usually clearly observed on a film in the waters view.

During exodontia a fracture of the floor of the sinus may occur and may result in an oro antral fistula. We attempted to obtain a quantitative index of the x ray opacity of the maxillary sinus using x ray films in the waters view. There may be a prolapse of the sinus lining into the oral cavity. Citation needed projecting into the floor of the antrum are several conical processes corresponding to the roots of the first and second maxillary molar teeth.

Small arteries from the facial maxillary infraorbital and greater palatine arteries. Hemorrhage partially fills the left maxillary sinus. Paired sinuses within the body of the maxilla. Bilateral frontal intraparenchymal hemorrhages.
