Sensory Retraining Facilitates Sensory Recovery After Mandibular Nerve Injury

Not Applicable

• Conditions: Injury of Trigeminal Nerve; Surgery; Mandibular Prognathism
• Interventions: Behavioral: sensory retraining protocol

• Registration Number: NCT01586598
• Lead Sponsor: Chang Gung Memorial Hospital

Brief Summary

The purpose of this study is to determine whether sensory retraining exercise could improve lip numbness caused by bilateral sagittal split of mandible.

Detailed Description

The study is a prospective randomized controlled trial. The patients receiving bilateral sagittal split osteotomy and having lip numbness or paraesthesia will be included in this study. 80 patients will be included and randomized into two groups and there are 40 patients in each group. The control group is to maintain follow up in clinic and do not receive any sensory retraining exercise. The experimental group is requested to perform sensory retraining at home by themselves.
