We checked \u201csurgical dehiscence\u201d under microscopes, and also estimated the minimal threshold of electric current needed to change the electromyography of facial muscles using Nerve Integrity Monitor (NIM)\u20102 (Xomed, Minneapolis, MN, USA).<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>Forty\u2010three percent of cases showed \u201csurgical dehiscence\u201d and responded to electric stimulation of 0.7\u00a0mA or less. \u201cElectrical dehiscence\u201d (\u2264 0.7\u00a0mA) was presented in 73 (73.0%) cases, and 82.2% of these cases responded to 0.4\u00a0mA or less.
