Frey syndrome is a disease characterized by abnormal sweating, facial redness, and rare pain by stimulation of taste sense on the limited area dominated by the auriculotemporal nerve and great auricular nerve. Although the developmental mechanism and histopathologic cause of Frey syndrome are still being debated, the most reliable theory is based on injury of the parathympathetic nerve connected to the auriculotemporal nerve continuing to abnormal regeneration. The other theory is that the sweat glands develop an increased sensitivity after degeneration of sympathetic fibers. Therapy of Frey syndrome includes drugs, radiographic treatment, and surgical treatment; however, in most cases, treatment is not satisfactory. This is a case report on a 24-year-old male patient with Frey syndrome caused by the fracture reduction with retromandibular approach after multiple facial traumas and spontaneous healing without any special treatment.

대상포진후 신경통으로 체성신경 차단과 함께 성상신경절 차단을 반복적으로 받아오던 64세 여자환자에서 열세번째 우측 성상신경절 차단후 반대측인 좌측에 호너씨 증후군이 발생되었다. 그 원인은 명확하지 않지만 시술 도중 환자머리의 좌측회전으로 인한 해부학적 위치변화와 술자의 부정확한 지표선정 및 주사바늘의 안쪽방향등으로 약제가 중앙선을 넘어 주입된 것으로 추정할수 있다.

Objectives: Frey's syndrome is an infrequent complication after parotidectomy and its incidence varies from 23.5% to 50.8% in the literature. The objective of this study was to evaluate the actual incidence and clinical characteristics of Frey's syndrome. Methods: We analyzed 31 patients who underwent parotidectomy and serial Minor's starch-iodine test. The mean follow-up period was $66{\pm}26.1$ months (range, 24-118 months). The Frey's syndrome was analyzed using a questionnaire for the assessment of the subjective symptom and Minor's starch-iodine test for the objective measurement at 1, 3, 6, and 12 months after the surgery and then every 6 or 12 months. Minor's starch-iodine test was graded from 0 to 3 according to the area of discolorization. Results: Frey's syndrome occurred in 11 patients (35.5%) on the Minor's starch-iodine test. The mean onset of Frey's syndrome on the starch-iodine test was $13.6{\pm}10.4$ months after parotidectomy. Sixteen patients (51.6%) complained about gustatory sweating and flushing. The onset of the subjective symptom was $11.27{\pm}6.96$ months after the surgery. There was a significant correlation between the grade of the starch-iodine test and the severity of subjective symptoms (P <0.001). Various factors including size and location of tumor, incision method, and extent of parotidectomy did not correlate with the Frey's syndrome. Conclusion: The incidence of Frey's syndrome was 35.5% on the Starch-Iodine test, and the onset was about postoperative 13.6 months.
