Retrospective study design was used. The setting included University of Uludag School of Medicine Department of Otorhinolaryngology. Eleven patients who had undergone superficial parotidectomy for benign diseases in our clinic between June 2003 and August 2006 were included in the study. SCM muscle flaps were used in four patients. The GSR of the patients were measured using a MP 30 System. The Mann-Whitney U test was used for the analysis of data. There were complaints that resembled Frey's syndrome in three patients in whom flaps had not been performed. Patients with flaps had no complaints. In patients with flaps, no significant GSR changes were observed between the control and operated sides (P>0.05). In patients without flaps, the GSR levels were significantly higher on the operated side compared to the control side (P<0.05). GSR values on the control side did not show any differences between patients with and without a flap. However, there were significantly higher GSR values for the operated side in patients without flaps compared to patients with flaps (P<0.05). Application of a SCM flap is an efficient method by which to prevent Frey's syndrome, and the GSR test is beneficial both in diagnosiing and determining the severity of the disease as well as evaluating the efficacy of surgical techniques used to prevent Frey's syndrome.eninfo:eu-repo/semantics/openAccessFrey's syndromeGalvanic skin responseSuperficial parotidectomySurgeryArticle000422255600040S242S24566Supplement 1, Special Issue SI10.1007/s12070-011-0455-8
