Abstract:
An important number of patients are referred to the ENT specialist because of extraoesophageal manifestations of gastroesophageal reflux. The most alarming symptom is a paroxysmal dyspnea secondary to a laryngospasm. The patients report a laryngeal choking sensation associated to an aphonia. We report three cases of laryngospasm secondary to acid gastric reflux. The diagnosis was made with the clinical history, a laryngeal examination and a 24-hour pH-monitoring enabled us to demonstrate a clear temporal relation between the reflux episodes and the choking episodes. In conclusion, the pharyngo-laryngeal reflux is a possible cause of laryngospasm. In our three patients, a high dose antiacid treatment was efficient to bring a lasting relief of the symptoms.
