Horner’s Syndrome after Thyroidectomy: Two Cases Report

Background: Horner’s syndrome is defined as a combination of a series of symptoms following the injury of oculosympathetic pathway. This dysfunction is usually acquired during cervical surgery but rarely triggered by thyroid-surgery. Case Presentation: Here we present two cases secondary to thyroidectomy. Two young female patients, both diagnosed as tumor in left lobe of thyroid, had Horner’s syndrome after surgery. Fortunately, Horner’s syndrome was relieved after steroid treatment. Conclusions: Indirect mechanism involved in the lesion and the direct factor with mistaken section of nerve fibers may be responsible for Horner’s syndrome. Besides, Horner’s syndrome after thyroid surgery may be revisable after oral steroid treatment.
