ABSTRACT
Objective: Costen’s syndrome involves otoneurological and sinonasal symptoms associated with temporomandibular disorder (TMD). The current study compared the symptoms related to Costen’s syndrome in patients with arthrogenous versus myogenous TMD.
Methods: The study involved 294 consecutive patients with TMD, prospectively examined over a period of 6 months. These were stratified into 180 patients with arthrogenous TMD and 114 patients with myogenous TMD. A questionnaire and examination protocol was applied for each patient.
Results: Sinonasal symptoms were more common in the arthrogenous group (p = .001), whereas, hearing loss and vertigo were more common in the myogenous group (p = .001).
Conclusion: The current study provides support for central nervous system neuroplastic changes in the genesis of Costen’s syndrome symptoms.
