MSI tests showed that 56 (49%, 56\/115) patients had a positive MSI test. By combining the results from symptom questionnaire and MSI test, 23 patients (20%, 23\/115) had a severe form of Frey syndrome. Among all clinicopathological variables, the resected specimen size was the only significant predictor of the severe Frey syndrome group (<jats:italic>P<\/jats:italic>\u2009=\u20090.04). Disease pathology, tumor size, and adjuvant radiotherapy did not correlate with the severe Frey syndrome. Using receiver operating curve analysis, the best cutoff value of the resected specimen size (in largest dimension) for predicting severe Frey syndrome was 40 mm(sensitivity: 71.7%, specificity: 42.0%; area under the curve\u2009=\u20090.6483). The odds ratio of severe Frey syndrome with every 10 mm increase in the largest diameter of resected specimen was 1.30 (95% confidence interval, 1.01\u20101.68; <jats:italic>P<\/jats:italic>\u2009=\u20090.04).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Resected specimen size is the only significant predictor of developing severe Frey syndrome after parotidectomy.
