Inclusion Criteria:

  1. Taiwanese adult (18-40 y/o)
  2. Developmental dentofacial disharmony (Class III)
  3. Patients received orthognathic surgery (BSSO alone or with maxillary procedure)

Exclusion Criteria:

Arms of the Study

Arm 1

Arm 2

Arm Type

No Intervention

Experimental

Arm Label

control group

sensory retraining group

Arm Description

No intervention will be given to this control group. Spontaneous recovery of mandibular nerve will be assessed for sensory function.

Sensory retraining protocol will be applied this group. Any facilitation of sensory function in mandibular nerve will be assessed.

Outcomes

Primary Outcome Measures

sensory function test
The sensory function evaluation include objective and subjective examinations as the followings: Questionnaire Visual analogue scale (VAS) Two-point discrimination (2PD) Pain detection threshold (PD) tests Touch sensory threshold

5. Study Description

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.
