Effects of Low Medial Ramus Osteotomy on Neurosensorial Recovery During Post-Operative Period

Ali Törel Saygı21 enrolled

Overview

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.

Inclusion Criteria: * Patients with dentofacial deformity who needs orthognatic surgery Exclusion Criteria: * The patients with medical conditions that may affect the potential of nerve regeneration, * The patient who need additional osteotomies such as genioplasty or mandibular subapical segmental osteotomies * The patients with bad split or interrupted IAN * The patients with more than 5 mm expected buccal osseous gap between proximal and distal segments

Outcomes

Primary Outcomes

Functional Sensory Recovery

Kind of scale, calculated with different neurosensorial investigation methods. Scored between S0-S4. S0 means total sensory loss, S4 means total sensory recovery.

Time frame: 6 months
