Brief summary

The aim of this study is to compare the post-operative neurosensorial disturbances of Hunsuck-Epkerr and low and short medial osteotomy modifications of sagittal split ramus osteotomy. Patients at the ages of 18-35 with dentofacial deformity who applied for orthognathic surgery were included in the present study. The present study performed with split-mouth randomised controlled trial design, therefore osteotomies on one side were performed with Hunscuk-Epkerr modification and the contralateral side with low and short medial osteotomy modification. Double blinded evaluations of neuro sensorial alterations were performed at the 1st, 3rd and 6th months post-operatively. Painful stimuli, two-point discrimination, pressure and brush stroke direction tests were evaluated. Subjective neurosensorial recovery was also evaluated with VAS scores given by patients.
