A 15 year old who is otherwise a healthy girl who presented with a history of right-sided aural fullness and it’s constant, disabling dizziness that worsened with physical activity. Audiometric testing revealed conductive hyperacusis in the right ear, normal tympanometry and intact acoustic reflexes. Cervical and ocular VEMP testing demonstrated low threshold and large amplitude responses in the right ear. High resolution temporal bone CT scans (Fig.1) revealed NO evidence of a tegmen defect or a low-lying tegmen and intact arcuate eminence.
However, a prominent right-sided superior canal dehiscence is clearly seen in the posterior-medial aspect of the most cephalic portion of the superior canal of the right ear. What is the treatment plan that you would suggest? *This case is by Docplexus Editorial Team for educative purpose only.
