Clinical value and cost of a respiratory sleep-related breathing disorders screening service for snorers referred to a District General Hospital ENT department.

Sleep-related breathing disorders and snoring often co-exist in the community. We hypothesized that a significant proportion of patients referred from primary care to ENT surgeons for management of snoring might have significant sleep-related breathing disorders requiring medical management. The Respiratory Medicine Department at Whipps Cross Hospital, London, U.K. screened all such referrals using sleep questionnaires, overnight oximetry and diagnostic sleep studies where necessary as recommended by the Royal College of Physicians of London. Over 38 months, 115 patients were screened, of whom 43 (38%) had clinically significant sleep-disordered breathing. One-third were established on nasal continuous positive airway pressure ventilation and the remainder were mainly offered conservative treatment. The cost of the screening service is estimated at 14,000 Pounds for the initial year. The savings to the ENT service and the possible long-term benefits to the patients identified as having sleep-disordered breathing balance this. We conclude that screening all referred snorers for sleep-disordered breathing using a simple protocol identifies a significant number requiring medical management at a relatively low cost to the service provider.

A cost-effective and rational surgical approach to patients with snoring, upper airway resistance syndrome, or obstructive sleep apnea syndrome.

The past decade has seen several innovations in the surgical techniques available for treatment of patients with sleep-disordered breathing. Outpatient techniques such as laser-assisted uvulopalatoplasty (LAUP) and more aggressive procedures designed to address hypopharyngeal and base of tongue obstruction (genioglossus advancement and hyoid myotomy) have been developed and proven successful. We describe the efficacy of LAUP for snoring (72.7%), upper airway resistance syndrome (81.8%), and mild (mean [+/-SD] respiratory disturbance index [RDI] = 12 +/- 8.1) obstructive sleep apnea (41.7%) in 56 patients who underwent 132 LAUP procedures in a 26-month period. Thirty-two patients with more significant obstructive sleep apnea (mean RDI = 41.8 +/- 23.1) underwent multilevel pharyngeal surgery consisting of genioglossus advancement and hyoid myotomy combined with uvulopalatopharyngoplasty. The surgical success rate in this group of patients was 85.7% when commonly accepted criteria were applied. We recommend a stratified surgical approach to patients with sleep-disordered breathing. Progressively worse airway obstruction marked by multilevel pharyngeal collapse and more severe sleep-disordered breathing is treated with incrementally more aggressive surgery addressing multiple areas of the upper airway.

Outpatient uvuloplasty: an inexpensive, single-staged procedure for the relief of symptomatic snoring.

Outpatient uvulopalatoplasty is an inexpensive alternative to laser-assisted uvulopalatoplasty for relief of symptomatic snoring. This single-stage procedure successfully reduced snoring in properly selected patients. Patients reported improvement in most cases, with 55% indicating great improvement or complete resolution. Spouses reported 83% of the patients were significantly improved or resolved. To date we have had no complications, including bleeding, infection, or velopharyngeal insufficiency or stenosis.
