Comparative audiometric evaluation of temporomandibular disorder patients with otological symptoms.
ABSTRACT The purpose of this study was to assess the audiological status of temporomandibular disorder (TMD) patients with otological symptoms and to make comparisons with that of a control group of subjects without TMD and otological symptoms.
25 TMD patients with otological symptoms and 20 age and gender matched controls, 45 subjects in total, were included in the study. All subjects underwent a series of audiological tests that included pure-tone audiometry, impedance test and reflex tympanometry. The audiological parameters recorded in the two groups were compared statistically by means of unpaired t tests and corrected according to Bonferroni in the case of repeated tests.
The pure-tone thresholds at frequencies 125, 250, 500Hz, and 6kHz showed significant differences between the TMD patients and control subjects after the Bonferroni correction (p<0.007). Compliance peaks demonstrated significant differences when the TMD and control groups were compared (p<0.05).
The findings indicate that TMD patients with otological complaints have hearing impairment at low frequencies and also perhaps, at high frequencies.

ABSTRACT: Synopsis Physical therapists have an important role on the interprofessional team to provide care for people with temporomandibular disorders (TMDs). Diagnostic classification is a challenge in this population, given the complexities inherent in presentations of headache and orofacial pain, and is critical to selecting the appropriate intervention. The objectives of this paper were (1) to characterize the epidemiology and pathophysiology of the TMDs most commonly seen in the outpatient clinic, (2) to describe a systems screen to be used in the physical therapy examination to determine the need for interprofessional referral, and (3) to propose an approach for physical therapists to examine, evaluate, and classify patients with TMDs, based on previously validated methodologies. A modification of the diagnostic framework of the International Headache Society has provided the basis for the systems screen of people presenting with orofacial pain. The physical therapy examination and evaluation is based on the Diagnostic Criteria for TMD, developed and validated by a consortium of specialists from the American Academy of Orofacial Pain.
