The aetiology of ALS is still unknown and it is extremely heterogeneous in genetics and clinical presentation, being the respiratory failure the usual cause of death. We describe a case of a 61-year-old male patient referred to the otolaryngology consultation for a 6-month history of progressive solid dysphagia and dysphonia. The patient presented several voice alterations such as a dysarthric speech with hypernasal voice which evoked the hypothesis of a neuromuscular disease. That patient was observed by a neurologist and was submitted to an electromyography that confirmed the ALS diagnosis. This case highlights the key role of otolaryngologists in the diagnosis of ALS, in a way that many patients with a bulbar ALS form are initially studied by an otolaryngologist.<\/jats:p>","DOI":"10.1136\/bcr-2020-234504","type":"journal-article","created":{"date-parts":[[2021,2,23]],"date-time":"2021-02-23T10:56:37Z","timestamp":1614077797000},"page":"e234504","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Otolaryngologist\u2019s
