An interventional study of sensory retraining protocol in Injury of Trigeminal Nerve, Surgery and Mandibular Prognathism, sponsored by Chang Gung Memorial Hospital. Status unknown at 1 site in Taiwan. Open to participants aged 18 Years to 40 Years. Per ClinicalTrials.gov, last updated 2012-04-27.
Sponsored by Chang Gung Memorial Hospital · Not applicable, Interventional, and Supportive care
The purpose of this study is to determine whether sensory retraining exercise could improve lip numbness caused by bilateral sagittal split of mandible.
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.
59 studies on the registry are indexed under Malocclusion, Angle Class III; 13 are open to participants now.
This study's planned enrollment of 80 is above the median of 32 across 54 interventional studies indexed under Malocclusion, Angle Class III.
