Effects of chronic exposure to electromagnetic waves on the auditory system.

abstract：CONCLUSION:Surgery remains the preferred option for large vestibular schwannoma (VS). The presence of unpredictable intraoperative difficulties may convince the operator to suspend the surgery to avoid risks to patient life. Additional surgeries may be mandatory and are better performed using a transcochlear approach. ...
