title: Upper airway surgery benefits patients with obstructive sleep apnoea who cannot tolerate nasal continuous positive airway pressure.
abstract: Nasal continuous positive airway pressure (CPAP) is the mainstay of treatment for patients with moderate to severe obstructive sleep apnoea (OSA). However, tolerance and compliance are poor. An audit using the Christchurch Hospital ORL surgery database identified patients who underwent upper airway surgery for OSA. Tracheostomy and bimaxillary advancement patients were excluded. Adults with moderate to severe OSA (Desaturation Index (DI) >10 n.h(-1)), who had failed a trial of nasal CPAP, and had pre-operative and post-operative sleep study data were identified. Objective (DI) and Subjective (Epworth Sleepiness Score (ESS)) outcome measures were recorded. The database identified 69 patients who underwent surgery for snoring or OSA; of these, 25 patients formed the study group. Sixteen out of 25 improved (64 per cent) after surgery, seven out of 25 showed no change (28 per cent), two patients (eight per cent) showed deterioration in their DI. Forty-eight per cent of patients had >50 per cent post-operative improvement in DI. Fourteen out of 25 (56 per cent) had a post-operative DI <20 n.h(-1). Seven out of 25 (28 per cent) had a post-operative DI <10 n.h(-1). Upper airway surgery has a role in the management of selected patients with OSA who cannot tolerate nasal CPAP.
