Frey Syndrome treatment with botulinum toxin
Otolaryngology-Head and Neck Surgery, 2000Co-Authors: Pavel Dulguerov, Didier François Quinodoz, Grégoire Cosendai, P. Piletta, Willy LehmannAbstract: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.

Prevention of Frey Syndrome during parotidectomy
Archives of Otolaryngology-head & Neck Surgery, 1999Co-Authors: Pavel Dulguerov, Didier François Quinodoz, Grégoire Cosendai, P. Piletta, Francis Marchal, Willy LehmannAbstract: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 P P 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.

marathon of eponyms 6 Frey Syndrome gustatory sweating
Oral Diseases, 2009Co-Authors: C Scully, John Langdon, Jane EvansAbstract:The use of eponyms has long been contentious, but many remain in common use, as discussed elsewhere (Editorial: Oral Diseases. 2009: 15; 185). The use of eponyms in diseases of the head and neck is found mainly in specialties dealing with medically compromised individuals (paediatric dentistry, special care dentistry, oral and maxillofacial medicine, oral and maxillofacial pathology, oral and maxillofacial radiology and oral and maxillofacial surgery) and particularly by hospital-centred practitioners. This series has selected some of the more recognized relevant eponymous conditions and presents them alphabetically. The information is based largely on data available from MEDLINE and a number of internet websites as noted below: the authors would welcome any corrections. This document summarizes data about Frey' Syndrome.

intraparotid location of the great auricular nerve a new anatomical basis for gustatory sweating Syndrome
Plastic and Reconstructive Surgery, 2015Co-Authors: Gaoussou ToureAbstract:Background Gustatory sweating Syndrome (also known as Frey Syndrome or auriculotemporal nerve Syndrome) is thought to result from a lesion of the auriculotemporal nerve. A lesion of this nerve can lead to aberrant regeneration of nerve fibers to the sweat glands and blood vessels. The occurrence of signs outside the region of the auriculotemporal nerve prompted the author to search for another anatomical basis for this Syndrome. Methods The author dissected 46 great auricular nerves from their origin to the parotid gland and in the infratemporal fossa. The author investigated the different connections of the great auricular nerve with the facial nerve and the auriculotemporal nerve. Results The great auricular nerve was found to essentially be a parotid nerve. There was a set of intraparotid nerve connections on 14 of the 46 half-heads that were dissected. The author was able to discern three types of parotid great auricular nerve connections, which he designates as either type 1, connection with the trunk of the facial nerve and its branches; type 2, connection with the auriculotemporal nerve; or type 3, connection with the auriculotemporal nerve and the facial nerve with the formation of an intraparotid nerve circle. Conclusions Having clearly established the nerve connections of the great auricular nerve, the author believes that it is primarily this nerve that is responsible for gustatory sweating Syndrome. This allows for a better understanding of the sympathetic nervous system features and the manifestation of the Syndrome outside the region of the auriculotemporal nerve.
