OBJECTIVE: To study the correlation of obstructive sleep apnoea (OSA) and laryngopharyngeal reflux (LPR). DESIGN: A descriptive study. SETTING: Suez Canal University Hospital, Ismailia, Egypt. PATIENTS: 62 patients with polysomnography confirmed OSA. INTERVENTION: Patients were evaluated with ambulatory 24-h double channel pH monitoring. RESULTS: Mean reflux symptom index in the study group was 9 ± 5.5, and it was > 13 in all patients with severe OSA. Signs of LPR reflux were present in 34 (55%) patients. Abnormal reflux was detected in the distal oesophagus in 41 patients (66%) and in the proximal oesophagus in 21 patients (34%). Patients with severe OSA had significantly higher nocturnal LPR reflux episodes compared to patients with mild disease (P < .05). Number of reflux episodes and total duration of reflux during sleep are significantly correlated to degree of OSA (P < .05). No difference was found in relation to age or sex. Daytime reflux was not related to the degree of obstructive sleep apnoea (P > .05). CONCLUSION: LPR is common in patients with OSA. Patients with severe OSA have significantly higher nocturnal LPR. This should be considered when treating this group of patients.
