ABSTRACT
STUDY OBJECTIVES:
To compare adherence and treatment effects with an oral appliance (OA) in patients with different types of obstructive sleep apnea (OSA) those with mainly respiratory arousals ("arousers"), and those with oxygen desaturations ("desaturaters") at polysomnography (PSG).METHODS:
A prospective intervention study on 72 "tired snorers" with "normal" home sleep study (HSS), but later diagnosed as OSA with PSG, who accepted OA treatment. They were offered evaluation with a follow-up PSG and questionnaires, including the Epworth Sleepiness Scale (ESS), general health (GH), satisfaction, and side effects.RESULTS:
Sixty-six patients, 33 arousers and 33 desaturaters, were adapted to OA. The 1-year adherence rate was significantly higher among arousers (85%) than desaturaters (55%) (p = 0.034). Thirty-six of 66 patients underwent follow-up PSG; the apnea-hypopnea index was significantly reduced in 22 arousers from a median of 14 to 3 (p < 0.001), and in 14 desaturaters from 18 to 7 (p = 0.002; no significant group difference). ESS and GH showed no significant improvements in either group, although sleepy "arousers" (ESS ≥ 10) significantly improved their ESS. In total, 77% reported side effects, while 63% were still satisfied with the OA treatment. Gender analysis showed a significant dominance of females classified as "arousers" (p = 0.025).CONCLUSIONS:
OSA patients with mainly arousals at PSG showed higher adherence to OA treatment, compared to patients with desaturations. Both groups responded similarly to treatment improved nocturnal respiration, but only a small reduction of symptoms. We suggest that "tired snorers" with "normal HSS" should be offered PSG, and if OSA, also OA treatment.Palavras-chave
