ABSTRACT
Objective: The objective of this study was to validate the Japanese version of the STOP-Bang test for risk assessment of obstructive sleep apnea syndrome (OSAS).Methods: We retrospectively evaluated inpatients who underwent nocturnal pulse oximetry for OSAS screening at the internal medical wards.Results: One hundred and forty-four subjects were included the study, and 57 subjects who had a 3% oxygen desaturation index ≥10/hr underwent polysomnography. Seventeen and 29 subjects were diagnosed with moderate and severe OSAS, respectively. According to the receiver operating characteristic (ROC) curve analysis, the STOP-Bang test had a higher diagnostic value using a cutoff of 30 kg/m2 for BMI than using a cutoff of 35 kg/m2. A STOP-Bang score of 3 or greater had a sensitivity of 95.7% and specificity of 42.9% for detecting moderate-to-severe OSAS.Conclusion: The STOP-Bang test is a simple and useful tool for the risk assessment of OSAS.
ABSTRACT
1 case of OSAS was treated by valuating rapid maxillary expansion,sleep monitoring indicated that the device reduced nasal re-sistance and improved respiratory function of the patient.
ABSTRACT
@#Objective To explore the relationship between obstructive sleep apnea syndrome(OSAS)and the left ventricular diastolic dysfunction.Methods 20 consecutive newly diagnosed middle-aged OSAS patients(OSAS group)with neither controllable factors nor conditions affecting left ventricular diastolic function and 15 healthy control subjects(control group)were examined with echocardiography.Results The OSAS group exhibited left ventricular diastolic dysfunction compared with the control group,including increase of isovolumic relaxation time(P<0.05)and mitral deceleration time(P<0.05),decrease of E/A.There was no difference between tow groups in interventricular systolic thickness,posterior wall thickness,left ventricular systolic diameter,left ventricular diastolic diameter and others.Conclusion OSAS may be related with the left ventricular diastolic dysfunction.
ABSTRACT
Objective To evaluate the value of CT scan in patients with obstructive sleep apnea syndrome (OSAS) pre and post surgical operations.Methods 36 patients with OSAS and 50 normal adults were included in this study .The patients were divided into two typesaccording to the location of stricture site .The upper airway from roof of nasopharynx to glottis was evaluated using a Siemens Somatom Spiral Scanner and divided into upper pharyngeal and lower pharyngeal. The cross sectional area of two planes were measured and calculated. Meanwhile, The surgical effect of two types were compared by the pharyngeal area and AHI, SaO2 pre and post operations.Results Ⅰ type:The area of upper pharyngeal expanded (P0.05).AHI from 52.7 to 37.2 and SaO2 from 59.8% to 68%(P
ABSTRACT
Obstructive sleep apnea syndrome(OSAS) is a complex sleep disorder characterized by intermittent apnea secondary to sleep-induced obstruction of the upper airway. It occurs because of an airway obstruction anywhere between the trachea and the oronasal apparatus. The hallmark of OSAS is snoring, which is caused by vibration of the tissues of the pharynx as the airway narrows. The consequences of OSAS have focused on excessive daytime sleepiness resulting from sleep fragmentation and the cardiovascular derangements producing hypertension and arrhythmias. The primary method of controlling OSAS has been surgery. The current surgical procedures used for OSAS are tracheostomy, tonsillectomy, nasal septoplasty, uvulopalatopharyngoplasty, anterior mandibular osteotomy with hyoid myotomy and suspension, and maxillary, mandibular and hyoid advancement. We report a case of OSAS that was improved by genial advancement with infrahyoid myotomy and suspension. The patient was objectively documented by polysomnography, cephalometric analysis, and physical examination before the surgical procedure. The patient underwent genial advancement with infrahyoid myotomy and suspension. Patient had a good response from surgery.

Obstructive sleep apnea syndrome (OSAS) is characterized by repeated collapse of the upper airway, producing hypopnea, apnea, and ultimately, oxygen desaturation of hemoglobin. The major characteristics of OSAS are male predominace, obesity, hypersomnolence, and excessive snoring. Patients suffer deterioration of memory and judgement, irritability, morning headache, sexual dysfunction, and personality changes. Psychologic changes involving the cardiopulmonary system occur and may lead to life-threatening events. The presurgical evaluation includes nocturnal polysomnography, clinical examination, radiologic evaluation, and fiberoptic endoscopy. The current surgical procedures used for OSAS are tracheostomy, tonsillectomy, adenoidectomy, nasal surgery (septoplasty, partial turbinectomy), tongue reduction, uvulopalatopharyngoplasty (UPPP), anterior sagittal osteotomy of the mandible with hyoid myotomy and suspension, and maxillary, mandibular and hyoid advancement. Selection of the surgical procedure is based upon the severity of the sleep apnea, presence of a skeletal deficiency, presence of morbid obesity, and anatomic site of the obstructive process. Patient with OSAS documented by polysomnography, was evaluated by cephalometric analysis, and polysomnography before and 6 months following the surgical procedure. Patient underwent maxillary, mandibular osteotomies via Lefort I, SSRO, and genioplasty.

Objective:To explore the way of diminishing perioperative mortality of patient with obstructive sleep apnea syndrome(OSAS).Methods:The death reason of a patient with OSAS was analyzed and relevant articles were reviewed.Results:Asphyxia death mostly took place during anesthesia induction and convalescence as patients experienced general anesthesia for descending uranostaphyloplasty(uppp).Conclusion:The risk of anesthesia for the patient with OSAS must be fully recognized.Sedation amnesia and slow induction in pernasal intubation was an effective way for the operation.
