ABSTRACT
Mandibular advancing devices (MAD) are a therapeutic option for snorring, mild obstructive sleep apnoea (OSA) and some patients with moderate or severe OSA non compliant to CPAP. Aim: evaluating the efficacy of MAD in the treatment of snorring and mild OSA. Materials and method: MAD were applied in 26 patients (23 men) with a polysomnographic record (PSG) performed in the Polisomnography Lab II, Clinical Pneumophthysiology Hospital Iasi between 15 February - 15 October 2007. Nineteen patients were included (the rest were excluded for various reasons). Each patient was examined ENT. PSG used a Weinmann, Germany, device, SomnoManager 12.7 software. MAD were installed. After one month patients were checked with polygraph Weinmann SomnoCheck effort for evaluating the treatment efficacy.
Results: All included patients snorred in over 30% of total sleeping time (TST), having over 30 snorring episodes per sleep hour. The mean of snorring episodes per hour was 40.42 ± 7.15 at diagnosis and at evaluation after a month it was reduced to 20.64 ± 5.66 episodes per sleep hour. Mean value of AHI (apnoea-hypopnoea index) at diagnosis was 12.78 } 3.95 and after 1 month of MAD was 6.35 ± 2.84 events per sleep hour. Mean body mass index (BMI) was 27.7 kg/m2 } 2.89 and wasn't changed at check-up. Desaturation index was 19.15 ± 6.4 at diagnosis and improved to 7.94 ± 3.39 desaturation episodes per sleep hour after 1 month of treatment. The side effects reported were transient, consisting in discomfort of the temporo-mandibular joint and mild tooth ake. Most patients (16 subjects) use the device every night, displaying a high complienace to treatment.
Conclusions: The use of MAD proves to be efficient in snorring patients, reduce AHI and have a good associate a good compliance.
