REFLEX SWEATING can be classified broadly into three clearly recognizable categories: emotional, thermal, and gustatory. In this last category are several subgroupings ranging from postencephalitic and syringomyelia gustatory sweating, mentioned in most texts on neurology,1 to the morefamiliar auriculotemporal syndrome2-5 and other less-common entities, such as the crocodile tear syndrome,6,7 submental sweating,8 and postsympathectomy sweating.3,9

The auriculotemporal syndrome and most of the less-common entities mentioned above can be explained by the "aberrant regeneration theory" proposed by Ford6 and reexamined by Glaister et al.5 In these cases there is always a history of surgery, trauma, or suppurative infection which in some manner damages the nerve axons responsible for salivation and sweating. Subsequently, the regeneration of these axons is aberrant; in other words, the nerve supply to the salivary gland in part grows out to innervate the sweat gland, and vice versa. With this nerve
