Objective : To compare the subjective visual vertical (SVV) in otosclerotic patients before and after total stapedectomy with
tailored-made polyethylene strut.
Material and Method: Thirty-eight otosclerotic patients who underwent total stapedectomy with tailored-made polyethylene
strut between November 1, 2013 and December 31, 2014 were recruited.
Results : Nine out of 38 patients (23.7%) had abnormal SVV at 24 hours after total stapedectomy with tailored-made
polyethylene strut. The number had decreased to 3/31 patients (9.6%) one month and 2/22 patients (9.0%) two months after
surgery.
Conclusion : Evidence of otolithic organ injury has been found after total stapedectomy with tailored-made polyethylene
strut. Nevertheless, the injuries do not cause clinical symptoms. Patients recover quickly with good result in hearing gain
after surgery.
