Hearing Tests: Routine and advanced hearing testing and complete diagnostic evaluation for patients of all ages (including newborns). Brainstem Evoked Response Audiometry is used to assess hearing without the need for patient participation.

Separate appointments for evaluation, custom ear molds and follow up counseling may be required. Loss of Balance: Videonystagmography (VNG) is used to assist in diagnosing balance problems, including vertigo. 1-800-897-3307 © ENT Associates 2801 Westhill Drive Wausau, WI 54401 (715) 847-2021 Caring for North Central Wisconsin for over 40 years.
