“…In compiling a database of normal MRI results, Katzman et al [9] found only four temporal bone abnormalities in 1,000 asymptomatic volunteers. Similarly, in a series of 2,700 consecutive temporomandibular joint MRIs, Orhan et al [10] found radiographic evidence of otomastoiditis in only ten patients, seven of whom (prevalence, 0.39%) were found on subsequent otolaryngologic examination to have inflammatory disease of the ear. In a series of 644 screening MRIs to rule out retrocochlear hearing loss, Mirza et al [11] reported a 5% incidence of middle ear/ mastoid disease.…”

The aim of this study was to document patients with clinical mastoiditis who were reported to have mastoiditis by radiologists due to increased fluid signal intensity in the mastoid air cells on magnetic resonance imaging (MRI). Brain and temporal bone MRI reports between January 2004 and November 2009 were obtained from the radiology units of four different hospitals of the same Health Care Group. MRI reports for keyword mastoiditis and 406 patients were reported to have radiological mastoiditis on MRI due to increased fluid signal intensity. Otoscopic examination findings of 275 of these 406 radiological mastoiditis patients were documented and compared with MRI reports for clinical infectious otological disease. Forty-eight (17, 45%) (48/275) patients were found to have clinical otological disease on examination. The remainder of the patients (227/275, 82%) did not show any evidence of clinical otologic infectious disease. Of these 48 patients, 18 patients (37, 5%) had eustachian tube dysfunction, 13 patients (27%) had serous otitis media, nine patients (9%) had chronic otitis media, five patients (10%) had tympanosclerosis, and three patients (6%) had acute otitis media. The results of this study showed that MRI is not an effective diagnostic tool for mastoiditis. 82% of the MRI mastoiditis did not show clinical mastoiditis contradicting MRI reports. Fluid signal in the mastoid on MRI should not always be interpreted as mastoiditis by radiologists. Radiological mastoiditis does not necessarily point out to clinical mastoiditis.

“…Temporal air spaces have been recognized as an important contributor and path in suppuration of various pathological processes. Tumors of the mastoid process and ear may extend into the TMJ whereas otitis media or otomastoiditis may involve the TMJ and can even result in ankylosis (19)(20)(21)(22)(23).…”

Background: Detection of air cavities, so called pneumatizations, nearby to the temporomandibular joint (TMJ) area is important, as they represent sites of minimal resistance and facilitate the spread of various pathologies into the joint as inflammation, tumor or fractures and serve as a possible complicating factor in TMJ surgery. Aims: To determine the prevalence of pneumatization of the articular eminence (PAT) and roof of the glenoid fossa (PRGF) using cone-beam computed tomography (CBCT). Study Design: Cross-sectional study. Methods: Acquired images of 111 patients (222 TMJs) were evaluated. The presence of pneumatization was recorded at the articular eminence and roof of the glenoid fossa. Age and gender were recorded for all patients and type (unilocular or multilocular) and laterality were noted for the cases of pneumatization. Results:The mean age of the study group was 48.86±18.31 years. Among all the patients, 73 (65.8%) had PAT, while 13 (11.7%) had PRGF. Forty-two (37.8%) of the patients had PAT bilaterally; whereas 3 of them (2.7%) presented PRGF bilaterally. The percentage of PAT was higher for females (73.6%) than males (51.3%) (p<0.05). Conclusion: CBCT images are an accurate and reliable means of detection of the exact size and type of pneumatization and the relationship of pneumatization to the adjacent tissues. This is especially significant before a surgical intervention is planned in this region, in order to make a sound diagnosis.

“…While evaluating a case series of MRI scans performed to exclude cerebellar pontine angle tumors, Mirza et al noted a 5% incidence of middle ear and/or mastoid opacification, a figure somewhat higher than in similar studies . Katzman et al reported a 0.4% incidence of temporal bone disease on MRI scans performed on asymptomatic volunteers, a result that closely resembles figures produced by Orhan et al in 2005 (0.39%) …”
