Hoarseness in the elderly may be caused by medullary palsy, vocal cord atrophy, chronic laryngitis and other factors. 1. Medullary palsy: medullary palsy, also known as bulbar palsy, is damage to the glossopharyngeal nerve, vagus nerve, hypoglossal nerve and parasympathetic nerves emanating from the medulla oblongata. The elderly can be seen in motor neuron disease, posterior cranial fossa bottom or occipital foramen magnum area tumor, medullary cavernous disease, congenital malformations and other diseases caused by the presentation of slowly progressive dysarthria, speech slurred, nasal or hoarse voice. 2. Vocal cord atrophy: under normal circumstances, the vocal cord muscles will atrophy with age, which may result in thinning of the vocal cord or bowing of the vocal cord, resulting in low volume, hoarseness, weakness and other symptoms. 3. Chronic laryngitis: If the elderly’s throat is repeatedly affected by infections of viruses, bacteria and other pathogenic bacteria for a long time, or if they are accustomed to over-vocalizing, chronic inflammation may occur, resulting in hoarseness, dryness of the larynx, coughing, coughing up phlegm and other symptoms. If the elderly continue to hoarseness, it is recommended to consult a doctor in a timely manner, systematic examination to clarify the diagnosis, and actively standardize the treatment for the cause of the disease.
