OBJECTIVE To determine whether purified botulinum toxin might be as effective in the treatment of "crocodile tears" (gustatory epiphora) as it has been in the treatment of other hypersecretion syndromes such as Frey's syndrome (gustatory sweating). METHODS One patient with Frey's syndrome (gustatory sweating) was successfully treated with botulinum toxin. After this, two patients with chronic symptomatic crocodile tears (related to previous facial palsy) were treated with botulinum toxin injections into and around the lacrimal gland. RESULTS Both patients reported remarkable relief from symptoms and were observed to have no tearing while eating. CONCLUSIONS Purified botulinum toxin appears to be an effective treatment for crocodile tears.

D002908	Chronic Disease	Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care (Dictionary of Health Services Management, 2d ed).

D013547	Sweating, Gustatory	An autonomic disorder characterized by excessive sweating of the forehead, upper lip, perioral region, or sternum subsequent to gustatory stimuli. The auriculotemporal syndrome features facial flushing or sweating limited to the distribution of the auriculotemporal nerve and may develop after trauma to the parotid gland, in association with PAROTID NEOPLASMS, or following their surgical removal.
