摘要：Purpose: this study aimed to verify the occurrence of abnormal vectoelectronystagmography findings in patients with temporomandibular disorders (TMDs). Methods: in this cross-sectional study, patients diagnosed with TMDs underwent an otorhinolaryngological examination, audiological evaluation, and balance and vestibular function examinations, using vectoelectronystagmography. The tests performed were 1) spontaneous nystagmus, 2) saccadic movements, 3) pendular tracking, 4) optokinetic nystagmus gain and velocity, 5) rotational chair testing, and 6) post-caloric vertigo and the direction and velocity of the slow component of nystagmus. Results: thirty patients were selected (22 females and 8 males) with mean age of 30.8(14.9 years. Sensorineural hearing loss was seen in four patients (13.3%); the other patients (86.7%) had results within the normal range at all frequencies. Five patients (16.7%) showed abnormalities on the Romberg test and seven (23.3%) on the Tandem test. Abnormalities on the caloric test were seen in 40.0% of patients. More prevalence of headache (p<0.0001) and tinnitus (p<0.0001) was observed in patients with unilateral hyperreflexia, and dizziness, depression, anxiety, gait imbalance and falls in patients with bilateral hyperreflexia. Conclusion: patients with TMDs may present vectoelectronystagmography abnormalities characterized by unilateral or bilateral hyperreflexia and unilateral hyporeflexia of post-caloric nystagmus.
