The Effects of Chronic Otitis Surgery on SVV

The Effects of Chronic Otitis Surgery on Virtual Subjective Vertical

Inner ear trauma during chronic otitis surgery is one of the major concerns of Otolaryngology. Hearing thresholds or semicircular canals were investigated with this purpose. The investigator's aim is to test the utricle for surgical trauma.

All patients who will have surgery for ear will be tested before the operation and after the first day and the first week. Virtual SVV(Interacoustics) will be used for testing. The deviation angle from the vertical line will be measured when 15, 30, and 45-degree head tilt to the left and right side while they were standing.

Inclusion Criteria:

• Chronic Otitis Media
• Who had surgical treatment

Exclusion Criteria:

• A patient who had the vestibular disease before
• Neurologic disease
• Patients who had ear, brain and musculoskeletal surgery before
