| 3 | Objective tinnitus secondary to palatal tremor:Two case reports and brief literature review显示文摘Objective tinnitus is defined as a type of tinnitus perceived by both the patient and external observer.This paper presents two cases of objective tinnitus related to palatal tremor,along with a literature review.Palatal tremor is a condition characterized by soft palate involuntary contractions.Two types of palatal tremor have been described:symptomatic palatal tremor and essential palatal tremor,with different clinical manifestations.Diagnostic workup is based on medical history and physical examination,including direct oropharynx exploration and cavum visualization through nasopharyngoscopy.Brain MRI is mandatory in all cases.If a secondary origin is suspected,additional lab tests should be performed based on clinical suspicion.First-line treatment is botulinum toxin injection into the levator veli palatini and tensor veli palatini muscles,with velopharyngeal insufficiency being its main adverse effect.Other medications have not been shown to be effective. | Raúl Mellidez Acosta Miguel Saro-Buendía Lidia Torres García Maria Antonia Marcos Pena Carlos De Paula Vernetta | 2022 | Journal of Otology2022，17，2： | 0 |
