Successful Treatment of Obstructive Sleep Apnea With Use of Nasal Continuous Positive Airway Pressure in Three Patients With Mucosal Hemangiomas of the Oral Cavity

Cysts and benign tumors are uncommon causes of obstructive sleep apnea (OSA), and surgical removal is usually favored. In patients in whom an operation poses a high risk, however, nasal continuous positive airway pressure (CPAP) may prove beneficial. We describe three patients with hemangiomas of the oral cavity in whom polysomnography revealed moderate to severe OSA. In all three patients, nasal CPAP effectively decreased sleep-related disordered breathing events and dramatically improved their sleep. To our knowledge, this is the first report of OSA associated with hemangiomas involving the upper airway. Our experience suggests that nasal CPAP therapy is effective and well tolerated in such patients.

Effect of Shifting Costs to Patients on Specialty Evaluation for Sleep Disorders

OBJECTIVE To determine whether the introduction of out-of-pocket expenses to medical center employees would lead to decreased use of sleep disorder services. PATIENTS AND METHODS We retrospectively analyzed and compared the clinical and medical accounting data from visits by Mayo Clinic employees to the Sleep Disorders Center from January 1 to March 31, 2003, with that of January 1 to March 31, 2004, le, before and after a January 2004 increase in co-payments for evaluation and testing. RESULTS The total number of new patients evaluated in the first quarters of 2003 and 2004 was similar (113 vs 119; P = .37). Snoring, restless legs symptoms, hypertension, atrial fibrillation, and prior overnight oximetry testing were more prevalent in 2004 than in 2003 (P = .05, P = .01, P < .001, P = .003, P = .02, respectively). In contrast, insomnia and parasomnia complaints were less common in 2004 (P < .001). The mean apnea-hypopnea index, minimum oxygen saturation, and percentage of time with oxygen saturation less than 90% were all more severe in 2004 (P = .01, P = .001, P < .001, respectively). Sleep-related breathing disorders were more commonly diagnosed in 2004 (83.2% vs 67.2%; P = .02), whereas the diagnoses of nonbreathing disorders declined. CONCLUSION The insurance policy changes that resulted in larger employee co-payments shifted the spectrum of diagnoses seen at the Sleep Disorders Center toward more symptomatic patients, with more associated comorbidities, and patients who had more severe sleep-related breathing disorders. Total utilization did not decrease.
