This study investigated multidimensional treatment outcomes, including prognostic factors and side effects of vocal fold steroid injection (VFSI). ⋯ This study demonstrated significant improvements after VFSI in vocal nodules, polyps, and cysts. Occupational vocal demand and subtypes of vocal nodules are closely related to the treatment outcomes after VFSI, whereas symptom duration and LPR were significant prognostic factors for VFSI treatment outcomes in vocal polyps. Side effects after receiving VFSI were mostly self-limited without sequel, whereas the incidence rates might be varied by the injection approach and the timing for postoperative follow-up.

Herpes zoster is a neurocutaneous disease resulting from the reactivation of endogenous varicella-zoster virus (VZV) in dorsal sensory or cranial nerve ganglia. Rarely, this infection manifests without the characteristic dermatomal rash, a condition termed zoster sine herpete. Viral spreading of herpes zoster in the head and neck may manifest as various signs and symptoms because of the multiple possible combinations of cranial neuropathies. With only six cases reported in the English literature up to now, isolated neuropathies of the vagus nerve in the absence of cutaneous lesions tend to be misdiagnosed as idiopathic laryngeal paralysis. ⋯ Herpes zoster of the larynx is an uncommon condition that should be included in the differential diagnosis of laryngeal paralysis of idiopathic cause. We recommend performing a thorough examination of the pharyngolaryngeal structures and ordering PCR testing as the diagnostic method of choice.
