Surgical procedures for parotidectomy had been developed to gain adequate approach, prevent morbidity of nerve, and give esthetic satisfaction. We performed two cases of parotidectomy through facelift incision. One case was reconstructed with superficial musculoaponeurotic system (SMAS) flap and sternocleidomastoid (SCM) muscle rotated flap at the parotid bed. In second case, same procedures were performed, but collagen membrane was additionally implanted for prevention of Frey's syndrome. After surgery, two cases showed esthetic results without neck scar and hollow defect on parotid bed area.

Tumors of the deep lobe of parotid gland are rare. These benign tumors have usually been treated by total parotidectomy, which has functional and esthetic side effects. Recently, there has been a trend for operations of parotid gland benign tumors to be less radical and selective deep lobe parotidectomy has been introduced. This technique preserves the superficial lobe and facial nerve when tumor is located in the deep lobe. Selective deep lobe parotidectomy preserves parotid salivary function, minimizes the incidence of facial nerve damage and gustatory sweating (Frey's syndrome) and improves cosmetic outcome. We report a case of pleomorphic adenoma of the deep lobe that was successfully treated by selective deep lobe parotidectomy with satisfactory result.

OBJECTIVES: To correlate Frey's syndrome with subjective symptoms, Minor's starch iodine test results, and infrared thermography measurements, and to discuss the utility of thermography as a quantitative diagnostic method. METHODS: This study included 59 patients who underwent unilateral parotidectomy. A subjective clinical questionnaire and an objective Minor's starch iodine test were performed to evaluate the incidence of Frey's syndrome. Infrared thermography was performed, and the subjects were divided into seven groups according to the temperature differences between operated and unoperated sites. The thermal differences were correlated with the results from Minor's starch iodine test and the subjective symptoms questionnaire. RESULTS: Of the 59 patients, 20 patients (33.9%) reported subjective symptoms after eating; 30 patients (50.8%) tested positive for Minor's starch iodine test, 19 patients (63.3%) of which reported subjective symptoms. Of the 29 patients who were negative for the iodine test, 2 patients (6.9%) reported subjective symptoms. Thus, subjective symptoms were well correlated with Minor's starch iodine test (r=0.589, P<0.001). As the thermal differences with infrared thermography increased, the number of patients with subjective symptoms increased (chi2=22.5, P<0.001). Using infrared thermography, the mean temperature difference in the positive group for the iodine test was 0.82degrees C+/-0.26degrees C, and that in the negative group was 0.10degrees C+/-0.47degrees C. With increased thermal differences, more patients showed positivity in the iodine test (chi2=29.9, P<0.001). CONCLUSION: Subjective symptoms, Minor's starch iodine test, and infrared thermography are well correlated with one another. Quantitative thermography provides clues for the wide variation in the incidence of Frey's syndrome, and could be a useful method for diagnosing and studying Frey's syndrome.

BACKGROUND: This study was designed to evaluate the effectiveness of T3 sympathicotomy in treatment of palmar hyperhidrosis. MATERIAL AND METHOD: During the period of June to December 1998, 50 patients (24 females and 26 males) suffering from palmar hyperhidrosis either in isolation (n=37) or in combination with axillary hyperhidrosis (n=13) were operated. The mean age of the patients was 20 years. The bilateral sympathetic trunks were severed on the 3rd rib (2nd and 3rd ganglia) for the isolated palmar hyperhidrosis and on the 3rd and 4th ribs for the combined type using electrocoagulation scissors. A linear analogue scale was used to assess the degree of sweating on the palms, face, trunk, and feet (ranged 0 to 10:0 = anhidrosis: 10 = excessive sweating) as well as the patient's satisfaction with the surgery (ranged 0 to 10:0 = regret; 10 = completely satisfied). RESULT: All of the patients were relieved from palmar hyperhidrosis. A mean palmar sweat production score after T3 sympathicotomy was 1.5+/-0.8. Some degree of compensatory sweating had occurred in 39 patients (78%) with a mean score of 3.4+/-1.6. Gustatory sweating occurred in 2 patients (4%). The mean score of the patient's satisfaction after the surgery was 8.5+/-1.2. CONCLUSION: Palmar hyperhidrosis can be successfully relieved by the T3 sympathicotomy. When considering the advantages of T3 sympathicotomy with respects to a better preservation of facial sympathetic function, less occurrence of severe compensatory sweating, and lower incidence of gustatory sweating. We recommend T3 sympathicotomy as a treatment of choice for palmar hyperhidrosis.

BACKGROUND AND OBJECTIVES: Frey's syndrome is one of the potential sequelae of parotidectomy. Various medical and surgical treatments have been used in attempt to avoid this embarrassing condition. Recently, interposing barriers between the overlying skin flap and the parotid bed, such as the sternocleidomastoid (SCM) muscle flap, have been used to prevent this condition. The purpose of this study was to evaluate the preventive impact of using this flap on the incidence of Frey's syndrome and to identify the degree of severity in this syndrome between the use of SCM flap and no muscle flap. SUBJECTS AND METHOD: 40 patients who underwent superficial parotidectomy from June 1996 to August 2003 were divided into two groups. One group had SCM flap reconstruction (n=20), and the other did not (n=20). A subjective clinical questionnaire and the objective Minor's starch test were used to evaluate the incidence of this syndrome. A grading system was used to divide Frey's syndrome into mild or severe Frey's syndrome to determine its severity. The test of Pearson-x2 was applied. RESULTS: The association between sweating, flushing, or pain and the use of the flap was not significant. Also, there was no significant association with Minor's starch test and the use of the flap. There was a significant association with mild Frey's syndrome and the presence of the flap (p=0.014). CONCLUSION: It would seem that the sternocleidomastoid muscle flap does not reduce the incidence of Frey's syndrome, but does decrease the degree of severity in Frey's syndrome.

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.]]>

Frey syndrome is characterized by profuse facial sweating which is provoked by the taste of food. It has been described as a consequence of upper thoracic sympathicotomy. Botulinum toxin injection is a relatively new treatment modality for Frey syndrome. Botulinum toxin type A (Botox , Allergan, USA) had been successfully used to treat Frey syndrome occurring in a 38-year-old patient following thoracic sympathicotomy for palmar hyperhidrosis. A total dose of 100U of botulinum toxin (1.0U/0.1ml/cm2) injection resulted in a 6 months' resolution of sweating, burning, and flushing sensation on eating. During the follow-up period, no systemic side effects were experienced.

OBJECTIVE: Craniofacial hyperhidrosis patients have as much difficulty in personal relationships as palmar and axillary hyperhidrosis patients. Thoracoscopic sympathectomy for facial hyperhidrosis has been known to resect T1 ganglion, however, its inherent complications such as Horner's syndrome make surgeons hesitant to this method. We report the T2 sympathicotomy to treat craniofacial hyperhidrosis. METHODS: From June 2000 to July 2001, eight consecutive craniofacial hyperhidrosis patients underwent bilateral limited T2 sympathicotomy with 2mm-diameter endoscopes. Based on the follow-up from five to 23 months, the evaluation was made on the surgical outcomes, postoperative complications and patient satisfaction. RESULTS: All patients were relieved of excessive sweating in their faces and scalps. Complications related to the surgical procedures, such as Horner's syndrome and compensatory gustatory hyperhidrosis were not detected in any case. CONCLUSION: Limited T2 sympathicotomy has proven to be as effective as T1 sympathectomy and to be less complicated in treating patients with distressing craniofacial hyperhidrosis.
