pH monitoring in patients with benign voice disorders.

The aim of this study was to compare oesophageal pH-metry with laryngeal signs and symptoms in patients suspected of laryngeal reflux disease. A total of 60 patients with voice disorders, who were suspected of laryngeal reflux, were tested by single probe oesophageal pH monitoring. Thirty-two suffered from reflux laryngitis. A comparison of symptoms in patients with proven reflux to patients with no reflux was made. The symptoms were more frequent in the patients in the reflux group than in the non-reflux group. There was a significant difference between the groups with regard to dysphonia, sore throat, thick mucus and heartburn. Clinical signs appeared more frequently in the reflux group than in the non-reflux group. A significant difference was found between the groups regarding oedema of the vocal cords and hyperaemia and oedema of the posterior commisure, contact granuloma, posterior wall granulation and increased muscle tension. The patients in the reflux group were given medical treatment using omeprazole, and 76% logopedic voice training program. More than 50% of the laryngeal reflux patients were treated for more than 4 months before their voice problems had resolved. It is important to realize that signs of reflux laryngitis are not confined to the posterior commisure.
