Motor Vehicle Accident (MVA)
In audiology and hearing healthcare, motor vehicle accident (MVA) refers to a collision involving a vehicle that results in physical injury, including injuries to the head, neck, and auditory system. MVAs can cause or exacerbate a range of audiological conditions, including sensorineural or conductive hearing loss, tinnitus, vestibular disorders (dizziness and balance problems), auditory processing difficulties, and, in cases of significant head trauma, central auditory pathway dysfunction.
Head and neck trauma from an MVA can damage the cochlea, auditory nerve, vestibular organs, and related neural structures through direct impact, whiplash forces, or barotrauma from airbag deployment. The onset of symptoms may be immediate or may develop in the days to weeks following the accident. Audiological assessment after an MVA should include a comprehensive hearing evaluation, tinnitus assessment, and vestibular testing where indicated.
In Ontario, treatment for audiological conditions arising from a motor vehicle accident is covered under the Statutory Accident Benefits Schedule (SABS) through the at-fault driver's auto insurance policy. Audiologists treating MVA patients submit treatment and assessment plans through the Health Claims for Auto Insurance (HCAI) platform using standardized forms including the OCF-18.
