ABSTRACT
ABSTRACT: Among the treatment options for Obstructive Sleep Apnea (OSA) we have surgery to correct dentofacial deformities. OSA patients are routinely and predictably submitted to surgical treatment for dentofacial deformities. Frequently, orthognathic surgery and osseointegrated implants may be necessary to enable fixed rehabilitation. Patients submitted to orthognathic surgery have a transient decrease in blood supply after maxillary and mandibular osteotomy procedures, which can impair the results in these cases. This case report aimed to present and discuss the conflicting situation of an OSA patient in need of orthognathic surgery and dental implants. The treatment consisted of: (1) extraction of all teeth; (2) complete rehabilitation of the upper and lower jaw with dental implants and prosthesis without compensation; (3) bimaxillary orthognathic surgery to re-establish the maxillomandibular relationship and increase the upper airway volume. This rehabilitation sequence was a safe alternative for a case of Class II OSA, and rapidly achieved a final restoration with enhanced esthetics, functionality, biomechanics, maintenance of oral hygiene, and patient satisfaction.

RESUMO: Entre as opções de tratamento da Apneia Obstrutiva do Sono (AOS) temos a cirurgia para correção das deformidades dentofaciais. Freqüentemente, a combinação de cirurgia ortognática e implantes osseointegráveis pode ser necessária para permitir a reabilitação dental. Pacientes submetidos à cirurgia ortognática apresentam diminuição transitória do suprimento sanguíneo após procedimentos de osteotomia maxilar e mandibular, o que pode prejudicar os resultados nestes casos. Este relato de caso teve como objetivo apresentar e discutir a situação de um paciente com AOS que necessita de cirurgia ortognática e implantes dentários. O tratamento consistiu em: (1) extração de todos os dentes; (2) reabilitação completa da mandíbula superior e inferior com implantes dentários e próteses sem compensação; (3) cirurgia ortognática bimaxilar para restabelecer a relação maxilomandibular e aumentar o volume das vias aéreas superiores. Essa sequência de reabilitação foi uma alternativa segura para um caso de AOS Classe II, e rapidamente alcançou uma reabilitação com estética, funcionalidade, biomecânica aprimorada, manutenção da higiene oral e satisfação do paciente.

OBJECTIVE: To investigate the prevalence of obstructive sleep apnea in patients with ischemic stroke and to evaluate the effectiveness of nasal continuous positive airway pressure treatment. METHODS: Overnight polysomnography was performed by a computerized system in 19 subjects with ischemic stroke. Patients with an apnea-hypopnea index > 5 were considered to have obstructive sleep apnea. The appropriate level of continuous positive airway pressure for each patient was determined during an all-night continuous positive airway pressure determination study. Attended continuous positive airway pressure titration was performed with a continuous positive airway pressure auto-titrating device. RESULTS: Obstructive sleep apnea prevalence among patients with ischemic stroke was 73.7 percent. The minimum SaO2 was significantly lower, and the percent of total sleep time in the wake stage and stage 1 sleep was significantly longer in patients with obstructive sleep apnea. In two patients with severe obstructive sleep apnea, we observed a decrease in the apnea-hypopnea index, an increase in mean wake time, mean SaO2, and minimum SaO2, and alterations in sleep structures with continuous positive airway pressure treatment. CONCLUSION: As the diagnosis and treatment of obstructive sleep apnea is of particular importance in secondary stroke prevention, we suggest that the clinical assessment of obstructive sleep apnea be part of the evaluation of stroke patients in rehabilitation units, and early treatment should be started.
