Purpose:
The objective of this study was to evaluate the correlation between tinnitus and petrotympanic fissure (PTF) subtypes in patients diagnosed with temporomandibular joint dysfunction (TMD).
Materials And Methods:
One hundred patients with TMD (50 with tinnitus, 50 without tinnitus) were evaluated retrospectively using cone-beam computed tomography (CBCT). CBCT images were analyzed according to PTF subtype diagnosis (types 1 to 3). PTF structure was classified as type 1 (wide tubular formation), type 2 (double conical structure), or type 3 (single conical structure).
Results:
Although there was a negative correlation between tinnitus and PTF type (P < .001), there was no correlation between age and tinnitus or between age and subtype of PTF. There was no significant association between gender and tinnitus or PTF type (P > .05).
Conclusions:
A short, wide PTF (type 1) might be associated with an increased incidence of tinnitus in patients with TMD.
