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.

Condition or disease Intervention/treatment Phase
Injury of Trigeminal Nerve Surgery Mandibular Prognathism Behavioral: sensory retraining protocol Not Applicable

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.

Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Outcomes Assessor)
Primary Purpose: Supportive Care
Official Title: Sensory Retraining Exercise Facilitates Sensory Recovery After Bilateral Sagittal Split Osteotomy - a Randomized Controlled Trial
Study Start Date : April 2012
Estimated Primary Completion Date : September 2014
Estimated Study Completion Date : September 2015

Arm Intervention/treatment
No Intervention: control group
No intervention will be given to this control group. Spontaneous recovery of mandibular nerve will be assessed for sensory function.
Experimental: sensory retraining group
Sensory retraining protocol will be applied this group. Any facilitation of sensory function in mandibular nerve will be assessed.
Behavioral: sensory retraining protocol
  1. within one month after the surgery: facial massage and physical stimulation over lower face and lip, four times (20 minutes each time) a day
  2. one to three months after the surgery: brush and physical stimulation over lower face and lip, four times (20 minutes each time) a day
  3. three to six months after the surgery: brush, pin and physical stimulation over lower face and lip, four times (20 minutes each time) a day
Other Name: sensory retraining

Primary Outcome Measures :
  1. sensory function test [ Time Frame: one year after surgery ]

    The sensory function evaluation include objective and subjective examinations as the followings:

    1. Questionnaire
    2. Visual analogue scale (VAS)
    3. Two-point discrimination (2PD)
    4. Pain detection threshold (PD) tests
    5. Touch sensory threshold
