          Abstract

          Abstract Introduction: Obstructive sleep apnea is characterized by a reduced airflow through the upper airways during sleep. Two forms of obstructive sleep apnea are described: the central form and the obstructive form. The obstructive form is related to many factors, such as the craniofacial morphology. Objective: To evaluate the correlation between the morphology of the cranial base, of the mandible and the maxilla, and obstructive sleep apnea severity. Methods: Eighty-four patients, mean age of 50.4 years old; 73 males and 11 females with obstructive sleep apnea were enrolled in the present study. Patients with high body mass index and comorbidities were excluded. Lateral cephalograms and polysomnography were collected for each patient to evaluate the correlation between craniofacial morphology and obstructive sleep apnea severity. A Spearman’s rho correlation test between cephalometric measurements and obstructive sleep apnea indexes was computed. Statistical significance was set at p < 0.05. Results: Patients with a severe obstructive sleep apnea presented a reduction of sagittal growth of both effective mandibular length and cranio-basal length. The mandibular length was the only variable with a statistical correlation with apnea-hypopnea index. Vertical dimension showed a weak correlation with the severity of obstructive sleep apnea. No correlation with maxillary sagittal dimension was shown. Conclusion: Obstructive sleep apnea severity may be correlated to mandibular and cranial base growth. Facial vertical dimension had no correlation with obstructive sleep apnea severity.

          Resumo Introdução: A apneia obstrutiva do sono é caracterizada por um fluxo de ar reduzido nas vias aéreas superiores durante o sono. Duas formas de apneia são descritas: a forma central e a forma obstrutiva. A forma obstrutiva tem sido relacionada a vários fatores, como a morfologia craniofacial. Objetivo: Avaliar a correlação entre a morfologia da base do crânio, da mandíbula e da maxila e a gravidade da apneia obstrutiva do sono. Método: Foram incluídos no presente estudo 84 pacientes com apneia obstrutiva do sono, com média de 50,4 anos; 73 homens e 11 mulheres. Pacientes com alto índice de massa corpórea e comorbidades foram excluídos. Foram coletados cefalogramas laterais e polissonografia para cada paciente para avaliar a correlação entre a morfologia craniofacial e a gravidade da apneia. Foi computado o coeficiente de correlação de postos de Spearman (rho) entre medidas cefalométricas e índices de apneia obstrutiva do sono. A significância estatística foi estabelecida em p < 0,05. Resultados: Pacientes com apneia obstrutiva do sono grave apresentaram redução do crescimento sagital do comprimento mandibular efetivo e do comprimento crânio-basal. O comprimento mandibular foi a única variável que apresentou correlação estatística com o índice de apneia-hipopneia. A dimensão vertical mostrou uma fraca correlação com a gravidade da apneia. Não foi demonstrada correlação com a dimensão maxilar sagital. Conclusão: A gravidade da apneia obstrutiva do sono pode estar correlacionada ao crescimento da base mandibular e craniana. A dimensão facial vertical não apresentou correlação com a gravidade da apneia.

          A power primer.

          One possible reason for the continued neglect of statistical power analysis in research in the behavioral sciences is the inaccessibility of or difficulty with the standard material. A convenient, although not comprehensive, presentation of required sample sizes is provided here. Effect-size indexes and conventional values for these are given for operationally defined small, medium, and large effects. The sample sizes necessary for .80 power to detect effects at these levels are tabled for eight standard statistical tests: (a) the difference between independent means, (b) the significance of a product-moment correlation, (c) the difference between independent rs, (d) the sign test, (e) the difference between independent proportions, (f) chi-square tests for goodness of fit and contingency tables, (g) one-way analysis of variance, and (h) the significance of a multiple or multiple partial correlation.

            Clinical Practice Guideline for Diagnostic Testing for Adult Obstructive Sleep Apnea: An American Academy of Sleep Medicine Clinical Practice Guideline.

            This guideline establishes clinical practice recommendations for the diagnosis of obstructive sleep apnea (OSA) in adults and is intended for use in conjunction with other American Academy of Sleep Medicine (AASM) guidelines on the evaluation and treatment of sleep-disordered breathing in adults.

              Practice parameters for the indications for polysomnography and related procedures: an update for 2005.

              These practice parameters are an update of the previously-published recommendations regarding the indications for polysomnography and related procedures in the diagnosis of sleep disorders. Diagnostic categories include the following: sleep related breathing disorders, other respiratory disorders, narcolepsy, parasomnias, sleep related seizure disorders, restless legs syndrome, periodic limb movement sleep disorder, depression with insomnia, and circadian rhythm sleep disorders. Polysomnography is routinely indicated for the diagnosis of sleep related breathing disorders; for continuous positive airway pressure (CPAP) titration in patients with sleep related breathing disorders; for the assessment of treatment results in some cases; with a multiple sleep latency test in the evaluation of suspected narcolepsy; in evaluating sleep related behaviors that are violent or otherwise potentially injurious to the patient or others; and in certain atypical or unusual parasomnias. Polysomnography may be indicated in patients with neuromuscular disorders and sleep related symptoms; to assist in the diagnosis of paroxysmal arousals or other sleep disruptions thought to be seizure related; in a presumed parasomnia or sleep related seizure disorder that does not respond to conventional therapy; or when there is a strong clinical suspicion of periodic limb movement sleep disorder. Polysomnography is not routinely indicated to diagnose chronic lung disease; in cases of typical, uncomplicated, and noninjurious parasomnias when the diagnosis is clearly delineated; for patients with seizures who have no specific complaints consistent with a sleep disorder; to diagnose or treat restless legs syndrome; for the diagnosis of circadian rhythm sleep disorders; or to establish a diagnosis of depression.
