    Introduction: The studies that contra-indicate the use of an oral appliance (OA) for the treatment of Obstructive Sleep Apnea Syndrome (OSA) in the presence of signs and / or symptoms of temporomandibular disorders (TMD), or that report abandonment or suspension of their use due to pain caused by TMD, did not follow the same diagnosis criteria for TMD. Since the quality of life of individuals with OSA and TMD is further compromised by the presence of both syndromes, it is essential a assure diagnosis and a effective treatment for TMD. Among the treatments, the jaw exercises are considered as a supportive therapy (ST) in TMD. Objective: To assess the effectiveness of mandibular exercises, with support therapy for TMD in subjects with OSA and TMD considering the in reduction of pain, improved of the quality of life, and the compliance to treatment with the OA. Patients and Methods: All patients were evaluated prior and to 120 days after the use of the OA by means Fletcher & Lucket sleep questionnaire, the Epworth Sleepiness Scale, the SF-36 Inventory of quality of life, polysomnography, sleep and daily usage OA, clinical and radiographic evaluation of teeth and bone structure, and exam to observed sings and/or symptoms for TMD by the RDC/TMD criteria. The patients were randomized in two groups: support therapy (ST) and placebo therapy (PT). Results: Forty-five out of the 87 patients who were diagnosed with mild to moderate OSA referred to the use of the OA had their diagnosis confirmed by the RDC/TMD. Twenty-nine of those patients completed the 120 days treatment (15 patients in the ST group and 14 in the PT group). Patients in the ST group showed a significant improvement in their sleep complaints and improvement in a higher number of life quality domains when compared to the group of PT. As advances were made in OA positioning a significantly higher number of patients with persistent pain was observed in the PT group, in comparison to the ST group. There was reduction of pain intensity in the ST group compared to PT group. After advancement of the OA, higher compliance to the use of OA was observed in the ST group than in the PT group. Conclusion: Support Therapy with mandibular exercises showed significant improvement in quality of life and quality of sleep in patients with OSA and TMD who were treated with OA, being also effective in reducing pain and the increase the compliance to the OA treatment.

    A influência da via aérea superior no uso do aparelho intraoral de avanço mandibular para o tratamento da síndrome da apneia obstrutiva do sono

    Introduction: The treatment of choice for patients with obstructive sleep apnea syndrome (OSAS) has been the use of continuous positive airway pressure devices (CPAP), especially in moderate to severe cases, but in milder cases, the mandibular advancement devices (MAD), may be indicated. There are studies in the literature correlating the presence of anatomical abnormalities in upper airway (UA) with adherence to CPAP, but about the success and adherence of MAD the literature is scarce. Objectives: To compare the findings of a systematic evaluation of the UA on the success and adherence to treatment with MAD of patients with OSAS. Methods: We studied 28 adult patients with mild to moderate OSAS referred for treatment with MAD. The patients underwent sleep questionnaires and nasal symptoms, anthropometric and upper airway examination and polysomnography before and after 120 days using MAD. At the end of the protocol, patients were divided about the success (success and failure) and to the adherence (good adherence and poor adherence) and the findings were compared between groups. Was considered successful therapy the patients who reduced the apnea-hypopnea index (AHI) in 50%, being below 10/events per hour and the criterion for good compliance was the use of MAD in 90% of nights last week (Daily use of AIO). Results: The mean age was 48.8 ± 11.3 years, and there were 32.1% males and 67.9% female. Successful treatment with MAD was 64.3% and good adherence was 60.7%. About the adherence, there was no statistical significance in the parameters of UA analyzed. About the success, there was a predominance of patients with nasal alterations in patients with failure (p = 0.04), mainly at the expense of obstructive septal deviation (grades II and III) (p = 0.04). Conclusions: The sucess of treatment with AIO was significantly lower in patients with nasal alterations, which was not observed with regard to adherence.
