Primary Outcome Measures:
  • Facial muscle contraction after nerve block [ Time Frame: 30 minutes after lidocaine injection ] [ Designated as safety issue: No ]
    clinical and photographical study will be performed before and after neve block and relative contractibility state will be recorded

Enrollment: 10
Study Start Date: April 2013
Study Completion Date: July 2014
Primary Completion Date: July 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Neurotized facial muscle patients
injection of 1% lidocaine, 2mL for facial nerve block
Drug: injection of 1% lidocaine, 2mL for facial nerve block
injection with a fine needle of 2mL lidocaine in close contact of the facial nerve trunk
Other Name: facial nerve block following the O'Brien modified technique

Detailed Description:
The investigators want to study the physiology of nerve healing after lengthening temporalis myoplasty done for facial nerve impairment. The investigators already observed few cases of spontaneous neurotization and the investigators want to check the nerve command of the facial muscles. Clinical and photographic evaluations will be performed before and after a facial nerve block using 1% lidocaine.
