Temporal Bone pathologies are typically identified through CT scans and MRI's. These are machines that provide clear imaging to help us see what is going on. CT's are more common for fractures, and MRI's are more common for diseases.
Results from head trauma
Hearing loss and vertigo
Two types of fractures: Longitudinal and Transverse
Entire ear examined to ensure no other injuries
Antibiotic treatment
Surgical treatment
Healing on own
"31% of temporal bone fractures in the general population were caused by road traffic accidents followed by assaults and falls. Pedestrian injuries, bicycle accidents, gunshot wounds, all terrain vehicle accidents, sports injuries, and miscellaneous injuries accounted for 25% of cases"
(Diaz, Cervenka, and Brodie, 2016.)
Most common
Conductive and mixed hearing loss
Located in petrous area
Imaging used to identify
Mixed hearing loss with longitudinal temporal bone fracture
Right ear, mixed hearing loss, with air conduction masked and unmasked, and sloping
Sensorineural hearing loss
Vertigo
Facial paralysis (50% of time)
Transverse fracture progression of sensorineural hearing loss, high frequency configuration
Infection of the mastoid process
Can also have infection of the air cells
Most common cause is middle ear infection left untreated
Most common in children
Symptoms: pain, fever, otalgia, tenderness, swelling, typical signs of infection
One of leading causes of hearing loss if not treated
Diagnosed through typical ear examine followed by imaging
(Villines, 2019.)
Treatment: antibiotics, middle ear surgery, mastoidectomy
Simple Mastoidectomy: does not break through the posterior canal wall
Modified Radical Mastoidectomy: does not effect eardrum and ossicles
Radical Mastoidectomy: focus is saving life
Can lead to conductive hearing loss if left untreated or is a cronic condition for person
