Treatment of palmar hyperhidrosis by endoscopic clipping of the upper part of the T4 sympathetic ganglion. Preliminary results.

Endoscopic thoracic sympathetic surgery is a safe and effective method of treating palmar hyperhidrosis. Although hand dryness is the positive outcome of surgery, a residual amount of moisture in the hand is believed to improve the quality of life. Reflex sweating is a well-recognized and annoying complication that surgeons endeavor to avoid. From May 1, 2002 to July 31, 2002, 52 patients suffering from palmar hyperhidrosis were operated on by means of endoscopic clipping of the upper part of the T4-sympathetic ganglion (Upper ESB4). There were 24 males and 28 females with a mean age of 25 years. The mean follow-up period was 8.3 months. The patients answered a detailed questionnaire addressing the following issues: the recurrence rate, the degree of hand dryness, the extent of and areas of reflex sweating, the occurrence of gustatory and facial sweating, and the degree of satisfaction. The surgical outcome was satisfactory. Most patients demonstrated no or only slight hand sweating. Moderate sweating without discomfort was experienced in 9% of patients. Only 25% of patients required the use of lotion for hand dryness. Reflex sweating was observed in 87.5% of the patients but extremely uncomfortable in only 3.2%. Ninety-four percent of patients were satisfied. The remaining 6% were not satisfied but did not regret the operation. Although the duration of the follow-up period in this study was relatively short, we could obtain results comparable to other data in the literature. This is a simpler procedure and less damaging to the sympathetic system.

Water vapour loss threshold and induction of cholinergic urticaria.

A patient is described with cholinergic urticaria (CU) in whom the symptoms could be provoked by gustatory stimuli. The aim of this study was to investigate whether there is a threshold of sweating (monitored by skin water vapour loss (SVL) measurements) at which CU can be provoked. Provocations with lemon and sal-ammoniac liquorice induced transient sweating differing both in degree and duration. Only 'doubly salted' liquorice, which caused the most intense sweat response, resulted in urticarial lesions. This findings suggest a threshold dependency for the induction of CU. SVL measurement may be a useful method for the evaluation of sweating tests in CU patients.

Painful sweating.

OBJECTIVE: The authors report a case of spontaneous and gustatory facial pain and sweating. METHODS: The patient had frequent episodes of pain, sweating, and flushing bilaterally in the hairless skin of the ophthalmic and maxillary distributions of the trigeminal nerve. Gustatory stimuli (e.g., orange juice, pickled onions) reliably evoked episodes, but episodes also frequently came on spontaneously. The problem had begun during adolescence, about the time of topical treatment and then electrocauteries for facial warts. The patient reported benefit from tricyclic antidepressants, guanethidine, and trospium chloride (an anti-cholinergic quaternary amine used in Europe for urinary urgency). There was no pain or excessive sweating in other body areas, nor pain with exercise. RESULTS: Administration of edrophonium IV evoked pain and sweating, and ganglion blockade by IV trimethaphan eliminated pain and sweating and markedly attenuated responses to edrophonium. Trospium chloride also prevented edrophonium-induced pain and sweating. Bicycle exercise produced the same increment in forehead humidity as in a spontaneous episode but did not evoke pain. Tyramine infusion did not bring on pain or sweating, whereas iontophoretic acetylcholine administration to one cheek evoked pain and sweating bilaterally. Topical glycopyrrolate cream eliminated spontaneous, gustatory, and edrophonium-induced episodes. CONCLUSIONS: The findings indicate that facial pain and sweating can result from occupation of muscarinic cholinergic receptors after acetylcholine release from local nerves. The authors propose that after destruction of cutaneous nerves, aberrant regenerant sprouting innervates sweat glands, producing gustatory sweating as in auriculotemporal syndrome (Frey syndrome), and innervates nociceptors, producing pain.

Frey syndrome treatment with botulinum toxin.

The goal of this work is to present our results of the intradermic infiltration with botulinum toxin in patients with Frey syndrome. Sixteen hemifaces in 15 patients were studied. Gustatory stimulation was evoked by sucking on a slice of lemon while measurements were done on both hemifaces, with the normal side being used as a control. Skin temperature and color (erythema) were measured with a digital surface thermometer and a skin chromameter, respectively. Sweat quantity and surface were measured by using the previously described blotting paper and iodine-sublimated paper histogram methods, respectively. Testing was repeated 2 weeks after skin infiltration with botulinum toxin (dilution of 50 U/mL). The interinjection distances were 1 cm, and 0.1 mL (5 U) was infiltrated at each injection site. Frey syndrome complaints disappeared in all patients. Small residual amounts of sweat were measurable. The difference in sweat quantity before and after botulinum toxin infiltration was significant in every patient (P < 0.001). Skin temperature and color measurement gave inconclusive results. In conclusion, Frey syndrome treatment with botulinum toxin is an efficient and well-tolerated technique. Further work should address the optimal injection parameters.

Gustatory otalgia and wet ear syndrome: a possible cross-innervation after ear surgery.

HYPOTHESIS: The chorda tympani and Arnold's nerves have close approximation to each other and their cross-innervation is possible after ear surgery. STUDY DESIGN: A retrospective study was performed with a temporal bone pathology case and two clinical cases as representatives of such a possibility. Patients had severe otalgia and wet ear during gustatory stimulation. METHODS: A temporal bone pathology case was studied under a light microscope. Earache and/or wet ear were provoked during gustatory stimulation. Wet ear was tested with iodine-starch reaction after the subject tasted lemon juice. RESULTS: The temporal bone specimen has clusters of regenerated fibers in the tympanic cavity in the area of the chorda tympani and Arnold's nerves, suggesting a possibility of mixing. There are regenerated fibers in the iter chordae anterius, showing successful bridging of the chorda tympani nerves across a long gap. Detachment of the skin over the operated mastoid bowl obscured signs in one clinical case. Another clinical case of gustatory wet ear showed objective evidence of cross-innervation with iodine-starch reaction. CONCLUSION: The detachment procedure and iodine-starch reaction were the proofs that the signs were related to regenerated fibers. This is the first report of gustatory otalgia and wet ear after ear surgery.

Bilateral gustatory rhinorrhea following bilateral parotidectomy: a case report.

To the authors' knowledge, no cases of gustatory rhinorrhea following parotidectomy have been reported. A case is presented of a 28-year-old woman who underwent bilateral parotidectomies within a four-year period for congenital sialectasia and secondary infection. Both operations were complicated by Frey's syndrome and she also developed bilateral gustatory rhinorrhea. The successful management of this problem with bilateral vidian neurectomies and the refractory nature of her Frey's syndrome, finally controlled with tympanic neurectomies, are discussed.

[A case of cryptogenetic Frey's syndrome (author's transl)].

A case is reported of gustatory sudation of the cheek without previous parotid lesions. The results of pharmacological tests confirmed the neurogenic origin, blocked by atropine and stimulated by A.C. The published literature is reviewed and a tentative explanation suggested, based on the physiopathological mechanisms involved in Freis syndrome, that the lesion was of neuritic type but had not been recognized.

Frey's syndrome.

Frey's syndrome is a form of gustatory hyperhidrosis that develops following surgery, trauma, or disease of the parotid gland area. Several theories have been proposed to explain the resulting symptomatology. Treatment often is difficult or ineffective. An unusual case is presented involving a patient with delayed onset of symptoms who responded well to topical application of 20% aluminum chloride in anhydrous ethyl alcohol.

Prevention of Frey syndrome during parotidectomy.

OBJECTIVE: To evaluate the incidence of Frey syndrome (auriculotemporal nerve syndrome) after parotidectomy with and without placement of a subcutaneous implant and to examine the relationship between different implants and postoperative wound complications (hematoma, seroma, salivary fistula). DESIGN: A prospective nonrandomized controlled trial. SETTING: A primary care and referral university hospital center. PATIENTS: All patients scheduled for parotidectomy from April 1994 through August 1998 were eligible. Seventy patients were enrolled (2 refused). All 70 patients were evaluated for wound complications. Sixty patients with a follow-up of more than 1 year were evaluated for Frey syndrome. INTERVENTION: The choice of implant was left to the individual surgeon: 24 patients had no implant; 7, lyophilized dura implant; 7, polyglactin 910-polydioxanone (Ethisorb) implant; and 32, expanded polytetrafluoroethylene (e-PTFE) implant. OUTCOME MEASURES: The incidence of Frey syndrome was evaluated (1) subjectively by history (clinical Frey syndrome) and (2) objectively by using 2 newly developed tests. Both hemifaces were tested, with the normal side being used as a control. RESULTS: Clinical Frey syndrome was present in 12 patients: 11 without implants (11/24 [53%]) and 1 with an implant (1/46 [2%]) (P<.001). Objective tests were positive in 24 patients: 16 (76%) of 21 without implants and 8 (20%) of 39 with implants (P<.001). In the implanted patients, the objective tests were positive in 71% (5/7) of those with lyophilized dura, 14% (1/7) of those with Ethisorb, and 8% (2/29) of those with e-PTFE implants (P<.001). Wound complications included hematoma in 5 patients (7%), seroma in 4 patients (6%), and salivary fistula in 15 (21%). Salivary fistula occurred more frequently with Ethisorb (57%) and e-PTFE (25%) implants (P = .04). CONCLUSIONS: In patients without an implant, the incidence of Frey syndrome is 50% for subjective and 80% for objective evaluation. In patients with an implant, these incidences are 3% and 10%, respectively. Some implants are associated with a higher incidence of salivary fistula.
