Comparative audiometric evaluation of temporomandibular disorder patients with otological symptoms
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.

- "The incidence of these symptoms is in the range of about 5 to 30% for earache and about 30% for tinnitus    . The reported causes for otolaryngological symptoms include common embryonic origin of the ear and the masseter muscles and the compression of vessels, nerves, and ligaments by posteriorly translocated articular heads of the mandible in the middle and inner ear regions  . This is due to missing teeth not being replaced, particularly in the support zones, as well as to pathological teeth attrition, promoting the reduction in occlusal height and posterior translocation of articular heads in central occlusion  .

The functional disorders of the masticatory organ are the third stomatological disease to be considered a populational disease due to its chronicity and widespread prevalence. Otolaryngological symptoms are a less common group of dysfunction symptoms, including sudden hearing impairment or loss, ear plugging sensation and earache, sore and burning throat, difficulties in swallowing, tinnitus, and vertigo. The diagnostic and therapeutic problems encountered in patients with the functional disorders of the masticatory organ triggered our interest in conducting retrospective studies with the objective of assessing the incidence of otolaryngological symptoms in patients subjected to prosthetic treatment of the functional disorders of masticatory organ on the basis of the analysis of medical documentation containing data collected in medical interviews.
Material and methods:
Retrospective study was conducted by analyzing the results of medical interviews of 1208 patients, who had reported for prosthetic treatment at the Functional Disorders Clinic of the Department of Dental Prosthetics of Jagiellonian University Medical College in Cracow between 2008 and March 14, 2014.
Otolaryngological symptoms were observed in 141 patients. The most common symptoms in the study group were earache and sudden hearing impairment; no cases of sudden hearing loss were experienced.

ABSTRACT: The current study aimed to research the prevalence of temporomandibular disorders (TMD) in patients with subjective tinnitus, as compared to controls, and the association between symptoms of TMD, tinnitus, and chronic pain. Two hundred patients were divided into two groups, according to the presence (experimental) or not (control) of subjective tinnitus. The subgroups were determined according to the RDC/TMD criteria. The Pain Pressure Threshold (PPT) values of the masseter and temporalis muscles were recorded bilaterally, and a Visual Analog Scale (VAS) was used to address subjective pain. The most prevalent TMD subgroups in the tinnitus patients (p < 0.05) were myofascial pain with limited opening (39.0%), disc displacement with reduction (44.33%), and arthralgia (53.54%). The severity of tinnitus was significantly associated with the severity of chronic pain (p = .000). The PPT values were lower (p > 0.05), while the Visual Analog Scale (VAS) was statistically higher (p = .000) for the tinnitus patients. These results suggest that an association exists between TMD and subjective tinnitus.

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.
