General Surgery/sweating after parotidectomy
Consequent to swelling below my left ear, my parotid gland was removed by way of parotidectomy during 2007. For an year or so I didn't notice any discrepancies. But after that while eating, my face becomes reddish and I got sweat in that area, more so when I am eating spicy matter or when eating involves more chewing. Doctor says that it is common for a patient who has undergone parotidectomy and there is no need to cure this. Kindly advice me for a cure.
ANSWER: Dear Balasubramanian,
The symptoms you describe is known as Frey's Syndrome. It is a benign condition associated with the parotidectomy; there is no cure for it. Changing your dietary habits may help to decrease the excessive sweating; however, it is a small price to pay for such an extensive surgery, and so many other deforming complications that you were fortunate enough not to get.

QUESTION: Thanks for ur advice. It is a solace for my disturbed mind. Please let me know what dietary habits that I have to follow which may decrease the excessive sweating.
Citric foods, such as lemons, tend to produce the greatest symptoms.
However, after performing a literature review, I came upon several studies that use botulism (Botox), with good results in decreasing the amount of sweat. The following is an abstract from one of the research studies. I have included a link to the abstract. Good luck, please let me know how you make out.

Gustatory sweating, or Frey's syndrome, usually occurs after surgery or trauma to the parotid gland as a result of inappropriate parasympathetic cholinergic innervation of cutaneous sympathetic receptors. Numerous medical and surgical treatments have been proposed to prevent or treat this condition. The results, overall, have been unsatisfactory. Botulinum toxin is a relatively new treatment modality for Frey's syndrome. We review the literature and present our experience with 7 patients successfully treated with intradermal injections of botulinum toxin (Botox). Our technique and dosing are described. In all treated patients gustatory sweating ceased in the area injected with botulinum toxin. In 6 patients, symptoms reappeared, and additional injections were needed up to 4 times, at 6- to 8-month intervals. All patients now have been free of symptoms for a long period of time (mean 12.1 months). We strongly recommend intradermal injections of botulinum toxin as a safe, efficacious treatment for gustatory sweating.
