    OSAS is characterized by obstruction of the upper airway during sleep. Middle third face DDFs may be a predisposing factor for the syndrome. Cephalometric measurements have been studied to look for an association with polysomnographic changes. Goals: Define if ERMAC or AM provided improvement polysomnography and whether there is an association between polysomnography and cephalometry. Methods: 48 patients divided into 2 groups. Cephalometry and polysomnography at T1 and T2 were analyzed. Through of variance of means and categorical association, we sought identify which surgery provided the best results polysomnography. Pearson correlation was performed between both exams. Result: The variance of the means showed that SatminO2 and TTSsat02 <90% improved in ERMAC (p = 0.021 and P <0.001). At categorical association, ERMAC provided better results for IAH and SatminO 2. Pearson's correlation showed an association between AHI and BMI; awakenings and BMI. At ERMAC, there were associations between IAH and SNA, EAS and MP-H; awakenings and SNA, Co-A and MP-H. In AM there were associations between AHI and Co-A, PoOr-A and MP-H; awakenings and EAS; SatminO2 and SNA, SNB and Co-A. Conclusion: A ERMAC showed improvement of SatminO2 and TTSsatO2 <90% and improvement of categorical values ​​for AHI and SatminO2, when compared to AM. BMI correlated with AHI and awakenings. In ERMAC there was a correlation between AHI and ANS, EAS and MP-H; awakenings and SNA, Co-A and MP-H. In AM, between IAH and Co-A, PoOr-A and MP-H; awakenings and EAS; SatminO2 and SNA, SNB and Co-A.

    Titratable mandibular repositioner appliances for obstructive sleep apnea syndrome: are they an option?
    (Springer, 2007-12-01) Machado, Marco Antonio Cardoso; Juliano, Ligia; Taga, Marcel; Carvalho, Luciane Bizari Coin de; Prado, Lucila Bizari Fernandes do; Prado, Gilmar Fernandes do; Universidade Federal de São Paulo (UNIFESP)
    Mandibular repositioning appliances (tMRAs) designed with a titratable mechanism are effective to treat obstructive sleep apnea syndrome (OSAS) but are not widely used, although many studies have proven their value. the aim of the present study was to evaluate the efficacy of tMRAs in the treatment of OSAS on the criteria of the American Academy of Sleep Medicine (AASM; apnea/hypopnea index [AHI]< 5). Three hundred consecutive patients with a polysomnographic diagnosis of OSAS were referred for treatment with tMRAs between 2000 and 2003. Thirty-eight patients were excluded, and 262 concluded the titration protocol with tMRA that lasted 4 months. After titration, the patients were referred for a medical reassessment, and 83 patients (70 men) participated in the new polysomnographic exam with tMRA in place to access tMRA's efficacy. the mean pre- and post-treatment AHI were 26 +/- 17.7 and 4.8 +/- 5.3 events per hour, respectively (p < 0.00005). Fifty-three (62.6%) of the 83 patients were treated successfully (AHI < 5). Twenty-three patients had severe OSAS, and 12 of them (52.1%) were treated successfully (AHI < 5). Forty patients had moderate OSAS, and 26 of them (65%) were treated successfully. Twenty patients had mild OSAS, and 15 (75%) were successfully treated. Even when applying more rigid criteria such as those of the AASM, the expressive success rate obtained with the treatment of different degrees of OSAS indicates that tMRAs are an additional valuable option even for cases of severe apnea in which the patient does not tolerate continuous positive airway pressure or cannot afford this treatment, a fact quite common in Brazil and other developing countries.

    Tratamento dos distúrbios respiratórios do sono com retentor lingual: ensaio clínico randomizado cross-over
    (Universidade Federal de São Paulo (UNIFESP), 2018-12-20) Jung, Aline [UNIFESP]; Prado, Gilmar Fernandes do [UNIFESP]; Machado, Marco Antônio Cardoso [UNIFESP]; Prado, Lucila Bizari Fernandes do [UNIFESP]; http://lattes.cnpq.br/3844314810128616; http://lattes.cnpq.br/9922055566135433; http://lattes.cnpq.br/2617510083171521; http://lattes.cnpq.br/0793635204250482; Universidade Federal de São Paulo (UNIFESP)
    Objective. Check the efficiency of the dental appliance retainer lingual TSD (Tongue Stabilizing Device) in the treatment of Obstructive Sleep Apnea Syndrome (OSAS). Method. Randomized Clinical Trial Cross-over 64 patients with polysomnographic diagnosis of obstructive sleep apnea. Patients were randomized into two groups, one treated with TSD and another treated with acetate plate as control (CG) for 4 weeks. After 2 weeks of wash-out, the treatments were exchanged and the patients used the new device for 4 weeks. They were assessed with polysomnography, daily use and adverse events. Results: Patients who used the TSD device compared to control group had lower apneahypopnea index (AHI) (11.5±10.6 events/hour versus 14.8±11.7 events/hour, p <0.05), and more discontinuing use because of adverse events (18 patients, 28,1% versus 1 patient, 1.6%; p <0.05). Of the patients treated with TSD, 25 (39%) had a reduction in AHI and 14 (22%) patients reduced AHI to less than 5. TSD patients younger than 56 years compared to those older than 56 years had a lower AHI (8.1 ± 5.9 events/hour versus AHI 14.9 ± 13.4 events/hour, p <0.05), higher TTS (357.4 ± 64.8min versus 323.1 ± 48.8min; p <0.05) and better sleep efficiency (84.2 ± 9.7% versus 77.3 ± 7.4%, p <0.05). Conclusion: The treatment of mild and moderated OSA with TSD is an option that can benefits only a few number of patients. The reduction of respiratory events in the treated group was small, and only a fifth of the patients normalized the number of the events. The TSD connected to side effects that motivated the suspension of a high number of the patients.
