Abstract
- Fifty nine year-old male patient was referred for the correction of external auditory canal impatency according to anterior bony wall fracture of canal during the otolaryngologic treatment for hearing disorder. At clinical examination there are both temporomandibular joint(TMJ)pain,tenderness and left TMJ noise. We could find that if mouth was opened,external auditory canal impatented, and if closed, patented through otoscopy.We planned exploratory TMJ open surgery under clinical diagnosis of traumatic TMJ meniscus displacement and external auditory canal bony wall fracture. of under clinical diagnosis. During arthroplasty we found that posterior displaced meniscus pressured the fractured external auditory canal so we repositioned meniscus anteriorly.After arthroplasty,TMJ noise disappeared and hearing funtion recovered. We experienced hearing disorder due to TMJ meniscus posterior displacement, so we present a case report with literature review.
