Case of progressive facial hemiatrophy with cervical sympathetic hyperactivity as underlying aetiology.

Objective: We report a case of progressive facial hemiatrophy with cervical sympathetic hyperactivity as a possible underlying aetiology, based on clinical findings, three-dimensional computed tomography and thermographic imaging. Methods: We present a case report in which we describe the investigation and clinical course of progressive facial hemiatrophy, and we also review the world literature on this condition. Results: To our knowledge, this is the first report in the world literature of progressive facial hemiatrophy with cervical sympathetic hyperactivity indicated as a possible underlying aetiology, based on clinical findings, three-dimensional computed tomography and thermographic imaging. Conclusion: This syndrome may lead to atrophy of the subcutaneous adipose tissue with hyperfunction of the vegetative system. Although this is a rare syndrome, otolaryngologists should be aware of its symptoms, aetiology and treatment.
