Design outcomes

Primary

Measure	Time frame
Degree of vertical deviation in patients. Timepoint: After the operation, it will be the first, third and seventh day and the third and sixth month. Orthopedic examinations applied before surgery will be repeated in the follow-ups and the results will be recorded. All patients will be operated by one surgeon. Method of measurement: If there is, the amount of deviation through the prism cover test.	—
