BACKGROUND Hypoglossal nerve stimulation has been demonstrated to relieve upper airway obstruction acutely, but its effect on obstructive sleep apnea is not known. OBJECTIVE To determine the response in obstructive sleep apnea to electrical stimulation of the hypoglossal nerve. METHODS Eight patients with obstructive sleep apnea were implanted with a(More)
OBJECTIVE The aim of this research was to describe the postoperative respiratory complications after tonsillectomy and/or adenoidectomy (T and/or A) in children with obstructive sleep apnea syndrome (OSAS), to define which children are at risk for these complications, and to determine whether continuous positive airway pressure (CPAP) is an effective(More)
OBJECTIVES/HYPOTHESIS Electrical stimulation of the posterior cricoarytenoid muscle, when paced with inspiration, offers a physiological approach to restore ventilation in bilateral laryngeal paralysis without any of the disadvantages associated with conventional treatment. STUDY DESIGN A prospective study of six patients. METHODS The patients were(More)
Traditional measures of dysphonia vary in their reliability and in their correlations with perceptions of grade. Measurements of cepstral peak prominence (CPP) have been shown to correlate well with perceptions of breathiness. Because it is a measure of periodicity, CPP should also predict roughness. The ability of CPP and other acoustic measures to predict(More)
BACKGROUND Reduced upper airway muscle activity during sleep is fundamental to obstructive sleep apnea (OSA) pathogenesis. Hypoglossal nerve stimulation (HGNS) counteracts this problem, with potential to reduce OSA severity. STUDY OBJECTIVES To examine safety and efficacy of a novel HGNS system (HGNS, Apnex Medical, Inc.) in treating OSA. PARTICIPANTS(More)
Forty-six patients in an emergency room (ER) setting and 159 people suspected of driving while intoxicated (DWI) had their blood alcohol concentrations estimated by the angle of onset of horizontal gaze nystagmus and confirmed by blood alcohol analysis or breath-alcohol analysis (BAA) tests. In the ER group, 25/26 (96%) of legally intoxicated patients(More)
Hypoglossal nerve stimulation was investigated as a method to relieve an induced upper airway obstruction. Six dogs were implanted with a cuff electrode applied to each hypoglossal nerve and a pulse generator. After 4 weeks, the hypoglossal nerve was stimulated (50% duty cycle) for up to 8 weeks. At 12 weeks a double tracheotomy was placed, with a negative(More)
Reduced upper airway muscle activity during sleep is a key contributor to obstructive sleep apnea pathogenesis. Hypoglossal nerve stimulation activates upper airway dilator muscles, including the genioglossus, and has the potential to reduce obstructive sleep apnea severity. The objective of this study was to examine the safety, feasibility and efficacy of(More)
OBJECTIVE To compare the efficacy of endoscopic medial and lateral orbital wall surgery to 3-wall decompression in patients with thyroid eye disease. STUDY DESIGN AND SETTING A retrospective study of patients with thyroid eye disease with severe proptosis, exposure keratitis, or compressive optic neuropathy was conducted. RESULTS Mean reduction in(More)
OBJECTIVES/HYPOTHESIS To evaluate the acoustic and perceptual results of laryngeal reinnervation with ansa cervicalis to recurrent laryngeal nerve anastomosis. STUDY DESIGN Retrospective study of voice samples from 12 patients with unilateral recurrent laryngeal nerve paralysis, treated with ansa cervicalis to recurrent laryngeal nerve anastomosis.(More)
