The masseteric nerve is increasingly used for nerve transfers to reanimate facial movements, and imaging studies have shown a postoperative reduction in masseteric muscle bulk, but this finding has not been correlated clinically.1 Testing this nerve transfer approach with reference to a specific technique (the Borschel method), we sought to determine whether routine postoperative assessment of the masseter muscle with magnetic resonance imaging (MRI) or electromyography (EMG) is necessary in all cases or if specific indications should prompt assessment.
