Chronic sinusitis, chronic right mastoiditis, ear drainage, hearing loss, midline jaw cyst, with midline jaw pain. Neck: There is a incisive duct cyst that measures up to 26 mm. The adenoids, tonsils, and upper cervical lymph nodes are mildly prominent. The thyroid and major salivary glands are unremarkable. The osseous structures are unremarkable. There are small right maxillary sinus retention cysts. The orbits and imaged intracranial structures are unremarkable. Internal Auditory Canals: There are intrinsically T1 hyperintense secretions in the right mastoid air cells. There is also nonenhancing low T1 signal material that measures up to 10 mm in the right middle ear cavity with restricted diffusion. The bilateral cranial nerve 7 and 8 complexes are intact. There is no evidence of mass lesions. The inner ear structures, including the cochlea, vestibule, endolymphatic duct, and semicircular canals, appear unremarkable. The left mastoid air cells and middle ears also appear unremarkable.
