Congenital Horner's syndrome in otolaryngologic practice.

It is well known that Horner's syndrome is characterized by ptosis, miosis, and facial anhydrosis. However, the congenital form of Horner's syndrome is relatively uncommon, and it is scarcely known among otolaryngologists. In this report, two cases of congenital Horner's syndrome are described, both encountered recently in the recent author's practice. In the first case, the patient was seeking unnecessary medical treatment for a facial abnormality, not for his eyes. Thermography performed on this patient confirmed his complaint. Having had the first experience made diagnosis in the second case easier. Thus, although rare, this syndrome may be encountered in an otolaryngologist's daily practice and it is important to recognize its symptoms. It is suggested that some suffering from this disease may go undetected due to physicians' lack of familiarity with it.
