Mastoid ecchymosis, also known as Battle's sign, is a medical term referring to bruising that occurs behind the ear, typically indicating a fracture of the skull, particularly the temporal bone. This sign can suggest underlying trauma to the head, often associated with serious conditions such as skull base fractures or brain injury. It may appear several hours to days after the initial injury. Prompt medical evaluation is crucial for proper diagnosis and management.

The mastoid sinus, or the mastoid antrum, opens into the middle ear. It is part of the mastoid air cell system, which is located in the mastoid process of the temporal bone. The connection between the mastoid air cells and the middle ear helps to equalize pressure and drain fluid, playing a role in ear health.

No mastoid and maxillary sinus are two different bones
The mastoid sinuses are small air cells located in the mastoid process, which is a bony protrusion located behind the ear. The mastoid sinuses are connected to the middle ear and help regulate air pressure, as well as provide drainage for fluid.
