BACKGROUND The purpose of this study was to evaluate the effects of nasal surgery on nasal resistance, sleep apnea, and sleep quality in adult male patients with obstructive sleep apnea syndrome (OSAS). A prospective study was performed in OSAS patients who underwent isolated nasal surgery in a tertiary referral center. METHODS During the 3-year study(More)
OBJECTIVES An aim of this study was to assess the predictive power of an otorhinolaryngological examination of the upper airway to identify risk factors of obstructive sleep apnea syndrome (OSAS) in the patients. METHODS We examined 141 consecutive patients with OSAS. The morphological features were assessed by the designated otorhinolaryngologist while(More)
BACKGROUND The aim of this study was to investigate the effects of simple tonsillectomy on nasal resistance in patients with obstructive sleep apnea syndrome (OSAS). METHODS Conventional tonsillectomy was performed in 20 patients who were refractory to treatment with continuous positive airway pressure. The subjects consisted of 17 men and 3 women (mean(More)
OBJECTIVE To investigate the contributions of adenoid and tonsil sizes to obstructive sleep apnea syndrome (OSAS) in normal-weight children in two age categories: preschool and schoolchildren. METHODS Fifty-eight normal-weight (body mass index z-score<2) symptomatic children with OSAS (apnea-hypopnea index ≥ 2) were evaluated. The patients were divided(More)
OBJECTIVES/HYPOTHESIS To estimate the effectiveness of nasal surgery on the occurrence of sleep apnea, and to analyze the pharyngeal morphology of apnea patients whose sleep-disordered breathing was ameliorated postoperatively. STUDY DESIGN Prospective study. METHODS Thirty-five consecutive patients with apnea and nasal obstruction underwent(More)
BACKGROUND The role of increased nasal resistance in obstructive sleep apnea syndrome (OSAS) remains controversial. The aim of this study was to examine the pathogenetic role of nasal obstruction in obese patients with OSAS. METHODS Patients with OSAS (n = 125) at a university hospital were divided into three groups according to body mass index (BMI):(More)
OBJECTIVES The objective was to evaluate the significance of a portable sleep-monitoring device (Apnomonitor 5, Chest Co., Tokyo, Japan) to diagnose sleep apnea syndrome (SAS). METHODS The Apnomonitor 5 comprised an oronasal thermistor, a pulse oximeter, chest and abdominal belts to monitor the circumferences of the chest and abdomen, a microphone to(More)
CONCLUSION Persistent obstructive sleep apnoea syndrome (OSAS) occurs in approximately 20% of normal-weight children after adenotonsillectomy (T&A) and, in nearly 70% of them, it is caused by adenoid regrowth. Patients with severe or moderate OSAS showed a high incidence of persistent disease even after T&A. Allergic disease, severity and large adenoid size(More)
Manganese (Mn) transfer during haemodialysis and plasma Mn concentrations in haemodialysis patients were examined. Also, the correlation with plasma Mn levels and haematocrit levels and total plasma protein levels were studied. Fifteen volunteer outpatients undergoing haemodialysis showed significant increases in plasma Mn from 0.20±0.02 to 0.22±0.02 μg/dl(More)
