In this retrospective review of temporal bone high-resolution CT and CISS MR imaging of 98 hearing-impaired children, the authors found that the CISS MR imaging technique commonly used for inner ear evaluation performs poorly overall at resolving the endolymphatic duct and underdiagnoses enlarged vestibular aqueduct. If the endolymphatic duct is easily seen on CISS imaging, there is a .99% probability that the vestibular aqueduct is enlarged.

This systematic review of patients with middle ear sinonasal-type tumors with a history of primary sinonasal tumors shows a tumor pattern supporting the hypothesis that the Eustachian tube may facilitate the spread of sinonasal neoplasms from the sinonasal cavity to the temporal bone.

The current diagnostic reference standard for peripheral trigeminal nerve injuries is neurosensory testing in combination with clinical findings to determine treatment. MRN provides an alternative method for the diagnosis and staging of patients with PTN because of its ability to delineate anatomy and the exact location of injury. This study correlates injury grading based on NST and MRN, demonstrating similar rates of agreement with surgical findings in lower-grade injuries but higher rates of agreement between MRN and surgical findings than NST in higher-grade injuries.
